Using Ideas to Solve Challenges with the Strengths of Both Systems and Creativity

D-POPS GROUP has 23 group companies that we call partners (at the time of publication).

For this article, we interviewed Hidefumi Miyahara, the CEO of idealump Co., Ltd, which joined D-POPS GROUP in December 2023. (This interview was conducted in December 2024.)

◆The Founding of Idealump

Sugihara:
Today, we’re interviewing President Miyahara, CEO of Idealump. Thank you for your time. First of all, congratulations on receiving a special award this month at D-POPS GROUP’s annual all-hands event.

Miyahara:
Thank you very much!

Sugihara:
Of course Idealump’s performance was part of it, but I believe it was also an acknowledgement of your activities in the past year since you joined. For example, your company renovated the websites of D-POPS GROUP and other group companies, and you collaborated in various ways as well. Now, let’s get straight to it. Can you tell us about the journey that led you to found Idealump?

Miyahara:
I founded Idealump in 2008. I had been self-employed since around 2006…actually, at first, I was a starving artist. I composed music for idols and jingles for the radio. For about three years, I was living on only three or four hours of sleep a night, and I started to feel a bit depressed.

This is awful, I thought to myself, but let’s keep trying to work in the music business anyway! However, because I didn’t have much life experience, my jobs started to disappear one by one, and before I knew it, I was making only 30,000 yen a month. I knew I couldn’t make a living like that, so I decided to try something else, and that something was being a professional planner.

I knew I had to start by coming up with ideas, proposing them, and winning projects. I was very vague about what sort of planning I did, so I was involved in all sorts of things, like event planning, interior design for stores, and creating signs, pamphlets, flyers, and websites. It was then that I felt the most potential in website creation.

2008 was the year of the Lehman Shock, and while Yahoo was already around, flip phones still reigned supreme here. At that time in Japan, IT startups were barely beginning to emerge, but for some reason, that’s when I decided to start. To get projects, I just read one book on web direction and then relentlessly knocked on doors, ha ha. I read that book from cover to cover until it was practically falling apart, and drilled its contents into my head.

It’s a bit embarrassing to admit, but sometimes the clients still knew more than I did. They would ask me things like, “How will you handle SEO?”, and I honestly had no idea. But I would simply say “I’ll do my best!”, and pick it up on the spot.

Sugihara:
That’s totally the venture spirit!

Miyahara:
It’s true, a lot of people who start a company in the IT field these days work at a major IT company first and then go independent. On the other hand, I had absolutely no precedent like that to work from.

So, I had no friends or acquaintances in the IT industry back then; rather, most of my friends worked at construction companies, landscaping companies, and restaurants.

◆The Journey to Joining D-POPS GROUP

Sugihara:
You really started from the ground up. After about 16 years, your staff and sales were growing, and then about a year ago, you joined D-POPS GROUP. Could you tell us about that journey and the reasons behind your decision?

Miyahara:
The biggest reason was that I felt I had hit a wall with what I could do as a self-taught business leader. Just before COVID, our company had started to get a lot of work from government agencies. Many of those projects were set for delivery at the end of March, and we were expecting to see our sales grow. Then, around February, the pandemic hit. Suddenly, almost all of our projects, worth tens of millions of yen, had to be cancelled, and our sales plummeted.

So, when April and May came and there was nothing to do, I decided it was time to pivot the business. Until then, most of our work had come from advertising agencies and media companies, focusing on digital campaigns and promotions. It was about making things as attractive as possible. But in the end, in terms of revenue, that kind of work was extremely volatile. So, I started thinking about returning to what I originally wanted to do: making things. That’s when the company’s foundation began to more closely resemble its current form, creating services and business solutions using systems and technology.

That experience during the pandemic gave me a strong desire to learn more about management and focus on fundamental business principles. In the midst of all that, I felt I had reached the limit of what I could accomplish on my own, doing things my own way. When I thought about getting through the current era and about the remainder of my life, I wanted to do something more interesting, more fundamental, and bigger. I thought it would be a good idea for me to hang around people who could help me do that, so I started to meet with many different individuals, but out of all those encounters, the one with President Goto was the most memorable.

I met with the CEOs of many companies, and most of them would start the conversation by talking about numbers, scale, and business plans. But President Goto was the only one who opened up by talking about mindset and philosophy. Only about 1 in 10 people would talk with me that way. That left a very strong impression on me, and I was drawn to him. I thought, “I want to work with this company! I want to learn about business management from him!”

◆Business Overview

Sugihara:
So that’s how it happened. Now, D-POPS GROUP has many types of companies, but can you tell us about Idealump’s business?

Miyahara:
Our base is “digital manufacturing”. Within that, it’s important to us that we don’t just create things according to our own satisfaction, but rather focus on creating what customers request, providing services and solutions, and increasing their corporate value. President Goto often talks about the land, sea, air, and space strategy of D-POPS GROUP. In that military analogy, I see Idealump as a kind of weapons factory, in that we create the necessary tools to help the other group companies advance their strategies and work together with them to create new businesses.

Sugihara:
Over the past year, even within the group, you’ve been asked to do digital planning and website creation, amid other requests. Do you have your business broken down into specific categories?

Miyahara:
Honestly, we handle a fairly wide range of digital domains. We’ve expanded our diversity within the digital space rather than narrowing down our business, and there’s merit to that. However, not specializing in a single area also poses a challenge when it comes to management.

Sugihara:
In other words, instead of pinning yourselves down by saying “This is all we can do”, you listen to the client’s problems and then do your best to propose a solution that can be solved digitally.

Miyahara:
That’s right. The IT industry, in particular, changes very quickly, doesn’t it? For example, when flip phones gave way to smartphones, everyone focused on smartphone apps, and many app companies popped up. The next trend was social media, and a lot of social media companies were born, and then it was gaming. The speed of these changes is incredibly fast, so rather than trying to chase every trend, our approach is to propose the necessary solutions to solve our clients’ problems as they arise.

◆Company’s Situation During COVID-19

Sugihara:
That’s a great approach. Did the pandemic that began in 2020 have a big impact on your company’s operations?

Miyahara:
Putting it simply, as I mentioned earlier, the work we were getting from advertising agencies at the time tended to be heavily focused on the creative side. Within that, we found that our ability to handle the system side of things, as well, came in handy. On the other hand, large system integrator companies are usually strong in developing systems but not so good at creative work. So, our skills in UI/UX were in high demand. That’s how Idealump survived the pandemic: with a two-sided approach of having strengths in both creativity and systems.

Sugihara:
So, even during COVID, business was still active for large system integrator companies?

Miyahara:
Yes, that’s right. Companies that handle large-scale core system development operate on three- to five-year plans, so apparently their long-term projects kept moving forward even throughout the pandemic.

◆Market Situation

Sugihara:
Could you tell us about the current market now that the pandemic has ended? Is the overall economy on an upswing, has momentum returned, or is it pretty much the same? Is there any kind of tailwind now that COVID is over?

Miyahara:
It’s bounced back a bit, but in the IT sector, I feel like the market might dip again slightly in 2025. I think the areas of SES (system engineering service) and time-and-materials contracts will increase even more than they are now. So, if you miscalculate how to obtain projects and contracts, it could be a tough situation. At the same time, I believe there will be opportunities for those who can provide high-quality services.

◆Strong Points

Sugihara:
I see. So, what would you say are Idealump’s key strengths?

Miyahara:
One of our key strengths is our history of over 10 years of providing one-stop digital manufacturing. We’ve built a wide range of digital solutions across various industries, from entertainment to finance, and we now have a track record of over 1,000 projects. I feel that this experience and expertise is another one of our strengths.

Also, there aren’t many companies of our size that can effectively blend both systems and creativity to create high-quality, one-stop web services, so I think that’s also a key strength.

Furthermore, we have quite a few global team members, so we are strong in Japanese, English, French, Arabic, and other languages. I believe that having many successful cases with global projects is another unique aspect of our company.

Sugihara:
That’s very global! Was that by chance, or did you intentionally pursue it?

Miyahara:
Actually, our globalization started as a way to solve the problem of who would join a small startup like ours, which began with only two or three people. Over 10 years ago, it was difficult to recruit talented Japanese people, so we decided to try and hire talented foreigners—talented global talent. That was the trigger.

Sugihara:
How many employees do you have now?

Miyahara:
We have about 50 people in our Japan office right now. Of those 50, about 20% to 30% are international.

Sugihara:
I always had the impression that you were a very logical and analytical person because of how meticulously you seem to work, but now that I’ve had the chance to hold a conversation with you, I feel that you’re surprisingly warm and personable. What sort of leader do you consider yourself to be?

Miyahara:
Hmm, that’s a good question…but I don’t really like to be in the spotlight, so I guess I could say I’m the kind of leader who focuses on supporting everyone else. I’m also the kind of person who hopes everyone can have fun.

Continued in the next part.

[Entrepreneur Interview #18] Fuminori Akamatsu (opzt) – Part 1
Building Trust with Major Corporations and Creating a Staffing Business that Develops Human Resources In this first installment of a two-part interview, we asked Fuminori Akamatsu, opzt, Inc.’s founder and CEO, about their business operations, how they build trust with major corporations, their expansion into the technology sector, human resource development, and their approach to the generative AI era. (This interview was conducted in August 2026.) ◆Introducing a Nationwide Business with 5 Locations, Centered on HR and Technology Sugihara: Currently, 26 group companies belong to D-POPS GROUP. Today, we are interviewing Mr. Fuminori Akamatsu, president of opzt, Inc., which joined the group in 2018. Thank you for your time! First of all, although it is posted on your website (available in Japanese only), could you give us an overview of your business in your own words? Akamatsu: Our core operations are centered around two main pillars: our HR business, which includes staffing, recruitment, and outsourcing; and our tech business, which handles the IT technology sector. Since our founding, we have provided HR services primarily for the telecommunications industry, focusing on administrative roles, call centers, and sales and promotional support. We currently operate out of five locations—Osaka, Tokyo, Nagoya, Shikoku, and Fukuoka—with many team members working throughout Japan. Recently, we have been focusing not only on conventional HR services but also on the IT technology sector, rolling out highly specialized HR services for roles such as AI specialists, data scientists, and infrastructure engineers. Currently, we mainly provide System Engineering Services (SES) and operate on an outsourcing and contracting basis, but in the future, we hope to develop and release our own in-house products. Sugihara: By the way, could you tell us the origin of your company name? Akamatsu: It originally came from the desire for our company to be our clients’ first choice. However, the word “choice” itself implies picking from a variety of options, whereas “opt” carries the nuance of proactively selecting something, so we embedded our desire to become that kind of company into the name. Since there was already a famous company called Opt, we wanted to avoid using the same spelling. We added ‘z’, the last letter of the alphabet, to make a new word which we gave the meaning of “the ultimate, best company”. Sugihara: So you drew inspiration from English and coined a new word to make your company’s name. About how many employees do you have in terms of the scale of your staffing? Akamatsu: Including both our headquarters staff as well as all of our dispatch employees, there are currently about 550 people registered with our company. ◆Building Trust from Year Two: Forging Bonds with NTT Sugihara: You have a very large pool of talent. How do you go about connecting with the clients where you dispatch your employees? I’ve heard before that you have many clients related to NTT. How did you manage to get your company involved with such a massive corporation? Akamatsu: A major factor is that when I was working as a corporate employee, I was given a lot of responsibility within NTT Group. Even though I was really just a young kid at the time, various key figures took me under their wing, allowing me to build not only business relationships but also deep interpersonal trust. Later, when I decided to start my own business, an NTT executive who had been a great mentor to me said, “If you’re going independent, I want to support you,” and offered to help me as an advisor. While that’s not the only reason, when I launched my business, former colleagues and other excellent individuals within NTT helped me out in various capacities. Because many of these individuals had long-standing trust, networks, and lots of personal connections with major companies like NTT, leveraging those connections to establish business deals became our starting point. And then, truly miraculously, we were able to sign a contract with NTT at the very early stage of our second year in business. Given that we didn’t have a Teikoku Databank rating at the time and weren’t yet the kind of company that they would typically even look at, I think our dealing with NTT was quite the exception. Sugihara: I believe your clients include other major corporations besides NTT. Many startups struggle to establish working relationships, so how did you and your management team pave the way for that? Akamatsu: We were truly fortunate to do business with a massive company like NTT in our second year, as it allowed us to learn through trial and error the difficulties of working with large corporations (things like information management, compliance, and talent quality). Because we were able to build a certain level of trust with NTT and establish an organizational framework for engaging with major companies, we were able to apply that to other large corporations, which helped us to get up and running relatively quickly. As has been the case for a while, rather than sales strategies that simply win contracts, we value strategies that focus on how long we can sustain those contracts. I believe our ongoing transactions with major companies like NTT and Docomo are the result of gradually building things up, one step at a time. Sugihara: What do you specifically pay attention to in order to maintain business with major corporations, or what do you think is the reason you enjoy such favor with your mentors? Akamatsu: I truly believe it’s the accumulation of consistently keeping small promises. It’s about trust—ensuring that the quality of our talent, compliance, and information management are solid, as I mentioned earlier. When a problem occurs on-site, we don’t hide it; we report it immediately and communicate how we will improve as a company. The larger the company, the more they scrutinize these aspects. So, we immediately and thoroughly address each issue. Our employees also strictly adhere to this principle, and I think the accumulation of all these efforts is what makes us stand out. We started from nothing, and while our initial entry point may have been personal connections, I don’t believe business relationships last this long purely on personal ties. It’s all about the cumulative effort. ◆From Routine Tasks to Highly Specialized Fields: Differentiating Their Business in the Era of AI Sugihara: I have the impression that your services have pivoted over these past 13 years. In particular, you recently started a tech-related staffing business. How are you differentiating yourselves in that area? Akamatsu: We didn’t originally set out with a conscious decision to pivot. Rather, as we kept our eyes on the HR market, we realized that routine and standardized tasks would inevitably become automated by AI. At the same time, we saw market movement showing an increased demand for talent capable of utilizing AI, such as data scientists and professionals in the AI and data fields. Our company realized about three or four years ago that if we just continued our traditional HR services, we would definitely be weeded out, so we knew we had to focus on high-growth sectors. However, we felt there was no point in doing the same thing as conventional SES companies. Therefore, we are specifically focusing on areas that directly tie into a company’s competitiveness moving forward, such as AI and data engineers, data scientists, and talent within the infrastructure field who can support data centers. Additionally, rather than only hiring individuals who already possess high skills, we are running a parallel initiative where we hire high-potential individuals with no prior experience, educate them, and develop them into specialized professionals while they gain practical experience. I believe combining the know-how we’ve cultivated in the staffing industry with specialized expertise in the technology sector is our unique point of differentiation that other companies don’t have. Sugihara: Your focus on the data center field, as you just mentioned, is definitely the right move. I’ve seen news from the US where, despite an increase in IT engineer layoffs, the demand for electricians is surging, to the point where even certified public accountants are quitting to become electricians or plumbers. I simply thought it was about having a tangible trade, but it turns out these jobs are related to data center construction. I hear there is a severe labor shortage, and while Japanese manufacturers are profiting from semiconductors and servers, there's also an ultimate demand for the people who actually install them. Akamatsu: That’s exactly right. In Osaka, in particular, data centers are rapidly increasing as backups for ones running in Tokyo. They are currently being built at a rapid pace with the idea that even if Tokyo falls, data can be protected in Osaka. Because these facilities require 24-hour monitoring and are often located in remote areas, telecommunications carriers are constantly struggling with labor shortages. We decided we wanted to tackle this head-on and are putting significant effort into it. I may use AI quite a bit myself, but people really are starting to use AI more and more. ◆Hiring Strategies and Educational Programs to Become Clients’ First Choice Sugihara: Now, I’d like to ask about acquiring the talent you actually dispatch to the clients receiving these services. I’ve heard of companies even within our own group that are struggling with recruitment. With costs rising and a shrinking talent pool to begin with, how is opzt tackling this? Akamatsu: Not to say it’s going perfectly well for us either, but we make a point not to rely on just one recruitment method. Our defining characteristic is that we use a mix of multiple recruitment channels—job boards, recruitment agencies, referrals, social media, and hiring events—depending on the job role and region. More important than that is becoming a company that applicants actively choose. Today’s job seekers look closely not only at the salary and job description, but also at what kind of experiences they will gain after joining, how it will lead to their future career, and how the company will treat them. Because of this, we make sure not to just say the good things, but to honestly explain everything: the job content, workplace environment, and expected roles. We place more emphasis on ensuring that the people who join us can thrive and work with us for a long time, rather than just focusing on the sheer number of hires. Sugihara: That’s wonderful. You mentioned that when people join opzt, you don’t necessarily just hire those who already possess high skills, but you also have programs to educate your employees. Could you elaborate on that? Can someone with no background in technology really become the kind of talent dispatched to that sector? Akamatsu: As part of our fundamental training, in addition to basic education on business etiquette, information security, and compliance, we conduct training tailored to each assignment. Especially in the tech sector, we don’t just have them learn online; we prioritize getting them to a point where they can use what they’ve learned in actual practice. We do this by creating assignments for them to present, supporting their acquisition of certifications, and pairing this with follow-up support from senior engineers. Furthermore, we believe that the ability to report, communicate, ask for help, and to understand a client’s intent is just as crucial as technical skill. So, we adjust our programs for each individual to cover these areas as well. Our goal is to develop talent that makes clients say, “I want to request this person for the job again.” ◆The Era of AI Agents: Stormy Seas or Smooth Sailing? Sugihara: Now, for this kind of staffing business—especially within the tech talent sector you’re focusing on—generative AI, and more recently, agentic AI, is a point of concern. Do you view this trend as a tough situation, or an opportunity? What countermeasures or approaches are you taking? Akamatsu: I think it’s definitely a storm and a critical situation, but more than that, I consider it a massive opportunity. As I mentioned earlier, standardized and routine tasks are increasingly being replaced by AI, and I can already feel that replacement happening in reality. However, if we just continue with the same kind of HR services we’ve offered up to now, I believe our company will undoubtedly disappear. On the other hand, I can feel a steady, upward trend in the demand for talent who can utilize data, talent who can implement AI into businesses, and talent with the level of communication and interpersonal skills that AI cannot replace. In that sense, if opzt itself can change and ride this wave, I believe we could be catching a very massive wave indeed. At our company, we are trying to develop talent capable of using AI even in non-engineering roles like administration, management, and recruitment, beyond just AI specialists and data scientists. By educating people to be on the side that uses AI rather than being used by it, I hope to create a differentiation strategy not found elsewhere. ◆Three New Initiatives for Further Growth Sugihara: Thank you. Are there any specific new initiatives you are currently working on for the further growth of your business? Akamatsu: There are three main things. First, as we discussed earlier, we are prioritizing the growth of our AI and data business, as well as the infrastructure sector surrounding data centers. Second, instead of dispatching individuals one by one, we are steadily increasing contracts with higher added value through outsourcing, where we provide support as a team. Third, even within our existing HR services, we are utilizing AI to enhance productivity in tasks such as recruitment, interviews, and staff follow-ups. Sugihara: Are there clients who need an entire team to be dispatched? Akamatsu: There actually are. Right now, engineers with those specific skills are either no longer available, or their rates have become expensive. So, we are seeing an increase in cases where we form and dispatch a team combining experienced professionals with the young talent we are training. As they grow, we add the next wave of new staff to the team, creating a cycle of continuous on-site training. Sugihara: I see, the younger members gain experience working alongside their mentors on the same job and in the same field with the same client, building their skills to eventually become leaders themselves. Akamatsu: Right. Our clients are also unable to train such talent themselves, so there is a strong demand to outsource the whole process to us. While this system can make things difficult sometimes, it allows our company to bring in inexperienced individuals, so we have recently been proposing to send whole teams to client companies quite often. Sugihara: Indeed, while sending someone individually helps that specific person build skills and experience, it raises the question of whether know-how is accumulating within the company itself. Usually, that person would have to come back and act as an instructor for internal training. But that training time doesn’t translate to revenue right away. Instead of making them just play the role of a teacher, they are essentially providing on-the-job training for younger members while both are getting paid by the client, and they themselves learn something through that, as well. Akamatsu: Exactly. So we are rapidly expanding this method right now. Interview conducted by D-POPS GROUP’s advisor Genta Sugihara. opzt, Inc.

[Venture Ecosystem Case Study] The Power of Three Arrows
“One Tech World”, a Development Alliance Formed by Three IT Companies “We lack engineers.” “One company alone can’t handle enterprise-scale projects.” These are the recurring problems in an IT industry facing severe labor shortages and increasingly complex project requirements. To address these challenges, three IT companies within D-POPS GROUP joined forces in May 2024 to form “One Tech World”, a strategic development alliance designed to leverage their collective strengths. The alliance consists of techbeans inc., an AI-leading company specializing in system development and AI solutions; @SOLUTION, the founding architect of this alliance, and a powerhouse in system development, infrastructure, mobile apps, and consulting; and idealump Co., Ltd, experts in web service development, UI/UX design, and other creative productions. This article explores how these three companies generate group synergy to secure large-scale enterprise contracts that would be unfeasible for any of them to obtain individually. 1. The “Wall” for Small to Mid-Sized IT Firms Certain areas of business are inaccessible for individual IT companies except for larger ones due to three main factors. ①Chronic Talent Shortages Large-scale projects require a massive headcount. Many firms must decline lucrative opportunities simply because they lack the internal resources. ②The Jack-of-All-Trades Trap Modern projects require a diverse elite skill set—PMs, designers, frontend/backend specialists, and infrastructure engineers. High-level mastery of every field within one company is rare. ③Ceiling on Internal Education Relying solely on internal projects limits a junior engineer’s growth. There are not many opportunities to learn from veteran engineers at other companies, so from an educational standpoint, they cannot overcome the limitations of in-house-only training. 2. The “Three Arrows” Concept: Unbreakable When Bundled There is a Japanese parable about “Three Arrows”, where a single arrow is easily broken but three held together are not. ①Exceeding the Limits of One To solve the challenges mentioned above, we arrived at a clear conclusion. By forming an alliance between the three IT companies within our group, we could flexibly handle large-scale projects that would be impossible for a single company to manage alone. Just like the Three Arrows—where a project that might snap a single firm’s resources can be successfully supported when three firms are bundled together—this vision was set into motion by a call to action from our organizer, @SOLUTION. ②The Right Talent, at the Right Time By forming this alliance, we can assign engineers across company lines, making it possible to take on project scales that a single firm simply could not accept. In an era where the shortage of IT talent is a major social issue, our ability to mobilize a large workforce all at once whenever necessary is a significant competitive advantage. ③Bringing Together Our Strong Points We are able to demonstrate our synergistic strength by combining the specific expertises of each company, including project management and direction, design, creative, frontend, backend, AI implementation, etc. Furthermore, skill sets that are difficult to assemble within a single organization can be fully covered when our three companies collaborate, vastly expanding the technical domains we can handle. ④Cultivating Talent Across Company Borders When veterans from one company work together with junior engineers from another on the same project, it creates growth opportunities that cannot be found within a single firm. Exposure to the different corporate cultures and technical approaches of other companies provides engineers with invaluable professional experience that accelerates their development. 3. The Three Coming Together: The Birth of “One Tech World” ①Why We Chose the Alliance Model We chose this system over a simple outsourcing relationship to ensure speed and quality by collaborating on a daily basis, rather than searching for new partners for every individual project. We believed that by teaming up with trusted colleagues who understand each other’s strengths and weaknesses, we could provide significantly higher value to our clients. ②Agility Through a Horizontal Structure By accepting projects as a horizontal alliance of three equals, we are able to keep the commercial flow simple and costs low while maintaining a flexible team structure. We have established a system where the primary contractor serves as the single point of contact while the alliance as a whole manages the project. ③Speed and Simplicity of Communication We utilize tools such as Slack to ensure smooth communication between our three companies. We also place a heavy emphasis on creating systems for information sharing and problem-solving through regular meetings. This commitment to open communication has been the key to increasing our collaborative speed. ④Development Rules as a Common Language We are actively developing standardized development rules for the alliance, clarifying the boundaries of responsibility and standardizing project management protocols. When different companies work together, keeping a set of rules that we have in common is essential for guaranteeing high-quality output. ⑤Keeping Everyone Up-to-date with AI Led by techbeans, we hold AI-related study sessions to create an environment where employees from all three companies can acquire AI utilization skills. As an AI-leading company, techbeans also actively publishes blogs and interviews, helping to drive AI adoption across the entire alliance. 4.The Journey to Launching: Inevitability, Rather than Coincidence Pre-2020 (Laying the Groundwork for Collaboration) The birth of One Tech World was preceded by a history of collaboration within the group. Around 2020, techbeans and @SOLUTION participated in the development of “DAMO”, the proprietary CRM system for D-POPS. This period allowed us to accumulate a track record of successful joint projects, cultivating the fertile ground necessary for a deep-seated partnership. December 2023 (Adding the Power of Creativity) idealump, a firm with significant strengths in design and creative production, joined D-POPS GROUP. This expanded the group’s IT capabilities into a three-company system, completing a lineup that could cover everything from technical development to high-end design. May 2024 (The Alliance Starts Moving) Following a call to action by @SOLUTION, the One Tech World development alliance was formally established between the three companies. Group synergy was demonstrated immediately, with idealump taking charge of renewing D-POPS GROUP’s corporate website during the same period. 2024–2025 (Expanding to Over 20 Collaborative Projects in 18 Months) In the year and a half or so since the alliance’s inception, the number of collaborative projects within the group reached approximately 20. By establishing a solid communication infrastructure, we have realized a higher speed of collaboration than we ever had before. Honestly, the sense of momentum we are experiencing is unlike anything any of us felt in the past. November 2025 (Stepping Outward: DXPO Exhibition) One Tech World made its debut as a unified entity by co-exhibiting at a major IT seminar event series in Japan called DXPO. By highlighting our strengths as an alliance—such as our AI-integrated products and our deep pool of talented engineers—we are working to increase our appeal among external clients. 5. Future Challenges: Racing Through the AI Era as a Unified Trio ①Overcoming the “Turning Point” in Development Since the launch of the alliance, we have successfully driven more than 20 collaborative projects within the group. Through continuous efforts to streamline communication, we have achieved a level of collaborative speed that we’ve never experienced before. This has made it possible for us to handle projects of a scale and scope that would have been impossible for a single company to manage alone. ②Accelerating Development with AI The development landscape is currently at a major crossroads. As the industry shifts toward accelerating development speeds through AI, techbeans—as an AI-leading company—is spearheading this movement by publishing AI-related blogs and interviews and hosting internal study sessions for the alliance. By supporting the employees of all three companies in mastering AI, we are significantly strengthening the collective development power of the entire alliance. ③Becoming the “Preferred Choice” through Creative Excellence Among the three companies, idealump possesses particularly strong design and creative capabilities, serving as a powerful asset when approaching external clients. While it comes a bit later than our initial launch a year and a half ago, we plan to significantly strengthen our inbound marketing strategy in 2026. We aim to capture new markets by fully utilizing the unique strengths of our three-member partnership. ④Opening the Door to Enterprise-Level Projects The alliance was brought together by the vision of the originator, @SOLUTION. Much like the bundling of three arrows, this partnership has turned the dream of approaching major corporations—once impossible for a single firm—into a reality. In an era of chronic IT talent shortages, the ability to mobilize a large, skilled workforce the moment it is needed serves as a massive competitive advantage. ⑤Expanding Collaboration with External Partners Moving forward, we plan to invite partner companies from outside D-POPS GROUP to participate in our projects. However, this will not be open to everyone. We will only admit partners who meet the specific high standards set by One Tech World. Our goal is not simply to become a large IT organization, but to be a collective of highly skilled IT talent and, above all, a group of companies that clients can trust implicitly. We will continue to increase the value of this alliance by balancing the expansion of our scale with strict quality assurance. 6. Summary: Choosing to “Bundle Together” In this article, we have summarized the initiatives of One Tech World, the development alliance formed by three IT companies within D-POPS GROUP. In this era when IT is accelerating faster and faster, issues that a single company cannot solve alone are increasing. Just as in the Three Arrows parable, by leveraging group synergy and mutually complementing each other’s resources, expertise, and talent cultivation, One Tech World represents a new collaborative model that IT companies in the future will be pursuing desperately. D-POPS GROUP will continue to harness the potential of our Venture Ecosystem, striving to make new, valuable contributions to society through the sharing and nurturing of exceptional IT talent. techbeans inc.

[Venture Ecosystem Case Study] Breaking Through the Online Wall! The Challenge of Three Companies to Expand Kodomamo Across Japan’s Mobile Phone Shops
“Is my child being bullied at school?” The parents and guardians of children everywhere share this same anxiety, and the parental control app Kodomamo seeks to resolve it using the power of AI. Today, this innovative service is gaining significant presence in mobile phone shops across Japan. This success is the result of a strategic partnership built on the strengths of three companies: the provider of the app itself, Adora Inc.; the company with extensive know-how in mobile phone shop operations, D-POPS Corp. (website in Japanese only); and the partner with a robust network across mobile phone shops nationwide, Advancer.inc (website in Japanese only). This article outlines how these three partners in our Venture Ecosystem tackled the challenge of distributing the Kodomamo app across Japan and led the project to a successful resolution. [The Challenge] Increasing Awareness of Kodomamo ① What is Kodomamo? Kodomamo*, provided by Adora, is an original parental control application designed to safeguard children. Specifically, when installed on both the child’s and parent’s smartphones, it can detect when a child is involved in dangerous online chats, enforce screen time limits to prevent overuse, and help prevent use of a smartphone while walking. *The name is a portmanteau of the Japanese words ‘kodomo’ (children) and ‘mamoru’ (to protect). The above graphic shows off some of Kodomamo’s key app features and accolades. However, when the service was first launched, it faced a major obstacle: the wall of awareness: how to get the people who need Kodomamo to know it exists. ② Points of Contact Between Kodomamo and Customers Kodomamo’s customer touchpoints were primarily limited to online channels and within the app itself. While efforts were made to direct users to the official website through social media and web advertisements, it was difficult to reach potential customers through passive advertising alone. Furthermore, the in-app chat function served only to support existing users and could not act as a contact point for new customers. While countless parents were worrying about their children being bullied, there was a stark lack of opportunity for them to learn about the potential solution of Kodomamo. Without overcoming this situation, the service could not truly contribute to society. [The Hypothesis] Reach Customers through Mobile Phone Shops To solve the challenges mentioned above, we hypothesized that a network of mobile phone shops throughout Japan could be the best way to connect Kodomamo with its customers. The realization of this hypothesis would not have been possible without support from D-POPS (with its expertise in managing mobile phone shops) and Advancer (with its strong network across shops nationwide). There are many benefits to introducing Kodomamo through mobile phone shops: ① Direct Customer Contact Staff can propose Kodomamo directly to parents who visit the store, especially when their children are getting their first smartphone. ② Support from Specialized Staff Just as carrier payment plans can be complicated, there is significant demand for support in selecting and setting up the most suitable app from a large selection. Knowledgeable staff can also assist both parents and children in getting the application installed and functioning on their devices. ③ Continuous Service Customers gain the peace of mind that they can ask questions at a physical store if any issues arise after they begin using the service. The concept of maximizing the value of a “face-to-face” experience in a physical store to solve problems that cannot be solved online perfectly embodies D-POPS GROUP’s core business model of Real Business × Technology × Group Synergy. [The Strategy] A Three-Pillar Approach for Expansion in Japan To turn our hypothesis into reality, we constructed a strategy based on three key pillars: ① Sales Channel Expansion Even among the approximately 7,000 mobile carrier shops around Japan, the major telecommunication company NTT docomo boasts an overwhelming number of “docomo Shops”, so we set our sights on working with them. To do this, we had to go through their proprietary product application system, an approval process necessary for retailers to handle their own unique products and services. Part of our strategy involved submitting our application through D-POPS, which manages a number of docomo Shops. After it was approved, Advancer leveraged their network of dispatched personnel to pitch our services at docomo Shops nationwide. ② System Integration Initially, Kodomamo only supported in-app purchases, which was unsuitable for sales in mobile phone shops. The in-app purchase model made it impossible to accurately track sales performance at each individual shop and provided insufficient incentives to those businesses due to high payment processing fees. To resolve this, we sought system integration that aligned with the shop owners’ business models, creating a mechanism that could visualize sales results and provide appropriate incentives. ③ Sales Scheme Construction Through consultation with D-POPS’ top sales members, who have extensive know-how of sales in mobile phone shops, we established the most effective sales scheme. Specifically, this involved combining the proposal with the mandatory guidance provided to customers under 18 regarding filtering services. This scheme allows Kodomamo to be naturally proposed as an option precisely at the moment parents are considering safety measures for their children’s smartphones. This multifaceted strategy, driven by the close cooperation of these three companies, transformed a mere concept into a plan ready to be executed across Japan. [The Execution] Growth Trajectory Accelerated by the Venture Ecosystem Here is a timeline of the execution based on the challenges, hypothesis, and strategies we explained so far. July 2024: D-POPS GROUP invested in Adora (Press Release on Investment in Adora Inc.) August 2024: The project was launched by a team from Adora, D-POPS, and Advancer. October 1, 2024: Sales were initiated at Smartphone Consultation Desk TOP1, D-POPS’ chain of mobile phone shops. At this beginning stage, they accumulated sales know-how, and promotional materials were produced by fellow group company graphD. Late October 2024: The proprietary product application for docomo Shops managed by D-POPS was approved. Armed with this approval and their newly-acquired sales experience, campaigns began at docomo Shops nationwide. Kodomamo received favorable reactions at many shops as “a socially meaningful and profitable product that is easy to sell together with a smartphone”. February 2025: The proprietary product application for Rakuten Mobile Shops managed by D-POPS was approved. This secured a new sales channel for future store expansion. The above graphic advertizes Kodomamo’s relevance for minors who use smartphones, its collaboration with the Aichi Prefectural Police, and a pricing guide with a list of available features. In this way, D-POPS GROUP’s Venture Ecosystem became a powerful engine accelerating Adora’s growth. [Results and Next Challenge] Rapid Expansion and Future Issues The sales channel expansion targeting docomo Shops, which began in earnest in November 2024, achieved adoption in approximately 300 stores in less than a year. The breakneck speed at which it spread is a significant achievement brought about by the collaboration of the three companies. However, the next challenge is now clear: improving the rate of acquisitions per shop. While the number of shops adopting Kodomamo has increased, there is some variation in the number of acquisitions at each location. To address this, Advancer, which has offices all over Japan, established a new support team composed of members with mobile phone shop sales experience. They are working to raise the overall performance by providing tailored support to shops struggling with acquisition rates. Additionally, D-POPS and Advancer are jointly supporting Adora in securing adoption with their partners, such as MVNOs (Mobile Virtual Network Operators) and device manufacturers. [Conclusion] Potential for Unlimited Growth through the Venture Ecosystem This article summarizes the case where three partners in our Venture Ecosystem collaborated to successfully tackle the difficult objective of boosting Kodomamo awareness—a task that would have been impossible for a single small company—and achieved substantial results. These efforts go beyond the simple provision of funds. Pooling the expertise and resources of various companies within the group in this way shows a strong case for the successful model of supporting the growth of a startup company. D-POPS GROUP will continue to leverage the unlimited potential of the Venture Ecosystem to create new value to benefit society. Written by: Shoichi Sakamaki (D-POPS Corp.)
