Partnering with All 3 Major Carriers within 3 Years of Founding:
The Trajectory of the Parental Control App Kodomamo
In Part 1 of this three-part interview series, we hear from Naoto Tomita, President and CEO of Adora Inc. (which develops and operates the child-focused SNS monitoring app “Kodomamo”) about the company’s path from founding to the present day. He also shares what has changed over the approximately two years since receiving investment from D-POPS GROUP Co., Ltd., in July 2024, and how Adora achieved the unprecedented feat of being integrated into au’s new mobile rate plan, the “U12 Value Plan”. This is the authentic journey of a startup that has pushed forward with relentless determination. (Note: This interview was conducted in June 2026.)
◆Reflecting on 2 Years Since Investment and 3 Years Since Founding
Sugihara:
Today, I am speaking with Naoto Tomita, President and CEO of Adora Inc., who became a member of our Venture Ecosystem following our investment in July 2024. President Tomita already gave us the pleasure of an interview in September 2024, but today we want to hear more about the continued rapid growth of Kodomamo and Adora.
(Read the previous interview here.)
President Tomita, we first met in May 2024, and two years have passed since then. It has also been about three years since your founding in July 2023. Looking back over the past two years since our investment and collaboration began, as well as the three years since founding, how do you feel? Please share your thoughts.
Tomita:
Well, receiving your investment reaffirmed and strengthened our mindset that this business and company belong not only to our employees, but to everyone, including stakeholders outside our team. It inspired a stronger sense of responsibility to do our best. Although there were tough times, I feel we worked tirelessly and stayed grounded. Looking back, it all went by in the blink of an eye.
Sugihara:
Does three years feel long or short to you?
Tomita:
Short. It just makes me feel like I need to work even harder.
Of course, I take pride in knowing we consistently did our best in everything we could. But looking back, of course there are also a lot of things I feel we could have done better. Still, the fact remains that we gave our absolute best at every moment, so my candid reaction is that these few years really flew by.
Sugihara:
Let’s look back at how your business has progressed over the past two years. Around the time we invested, you had just started fundraising from Keisuke Honda’s fund, right? Does it seem like things accelerated from that point?
Tomita:
It really does. Around that time, our projects with Docomo Shops were also just getting underway, and we had almost no revenue. We were pitching our vision, but traction hadn’t really kicked in yet, leaving us wondering if we could truly pull it off. We were so grateful to have you believe in us and commit at that stage.
From there, the sales from our partnership with Docomo Shops and our paid subscriptions started coming in, and traction gradually picked up. At the time of your investment, our revenue was nearly zero, so during the first year, we focused heavily on refining the service and building partner relationships with mobile phone shops. Thanks to that foundational year, our revenue surged dramatically from summer to autumn of 2025, growing by far more than tenfold all of a sudden.
Looking back over the three years, there was a clear flow between the preparation, fundraising, and acceleration phases, and I feel our efforts truly paid off with solid results between 2025 and 2026.

◆The Remarkable Feat of Integration into au’s New “U12 Value Plan”
Sugihara:
The biggest milestone during this period must be the integration of your flagship service, Kodomamo, into KDDI’s new monthly plan for au* smartphones in the summer of 2025, called the “U12 Value Plan.”
Note: au is the main consumer mobile network brand operated by KDDI Corporation, one of Japan’s major telecommunications carriers.
Tomita:
Indeed. We already had some distribution through D-POPS Corp.’s retail stores, but having our app officially built into a mobile carrier’s monthly plan was a first for us and an exceptionally major event.
Sugihara:
For au to incorporate a service from a company only about two and a half years old into a monthly plan was quite unprecedented. For a major corporation, adopting a brand that isn’t yet widely recognized carries risks. How did you manage to secure this major partnership?
Tomita:
It started when KDDI was searching for services to protect children’s safety and discovered ours. Within KDDI, there was an internal discussion that went beyond conventional filtering, recognizing the need to approach the subject from the basis of protecting children while still letting them use smartphones, rather than outright banning them. That was when our service caught their attention.

Sugihara:
What do you think was the deciding factor for KDDI to choose Adora after researching other services?
Tomita:
While there are other services for managing usage time, I believe we are still the only company in the market dedicated to comprehensive monitoring of SNS chat platforms like LINE. The ability to provide security measures for Japan’s most popular social network was a major selling point.
I also think our collaboration with the Aichi Prefectural Police and our track record with domestic partners added to our high evaluation. Naturally, because KDDI’s brand image was on the line, they carefully considered whether we were truly worthy of their trust before finalizing the partnership.
Sugihara:
Along with introducing your service to au customers, there was also some development required, right?
Tomita:
That’s right. We implemented features to integrate our services, such as a system allowing KDDI users to log in seamlessly with their au IDs.

◆Technical Superiority Competitors Can’t Replicate
Sugihara:
“Kodomamo” deeply intertwines AI and security technologies, and I would guess that high level of technical capability was another key factor in their evaluation. What specific technical advantages do you believe make you stand out? Where did you focus or struggle with during development?
Tomita:
Monitoring chats sounds simple, but executing it in practice requires various complex underlying technologies. Our core innovation lies in making it possible to analyze social media chat content, which was previously difficult to analyze.
We’ve been developing natural language processing models to determine potential dangers, image recognition models to detect inappropriate content, and ways to make those models lighter so they run smoothly on mobile devices. Being the first to accomplish what no one else had done—making chat analysis possible—is our greatest technical advantage.
At the same time, an intuitive UI/UX is equally crucial. I personally committed to working within the development team, and through everyone’s efforts, we were able to finalize and polish our product. No matter how superior a technology is, if it isn’t easy to use, it won’t achieve widespread adoption. Therefore, we have always been conscious of making the app clear and user-friendly.
Sugihara:
So, reading, analyzing, and detecting hazardous chats across platforms like LINE…are you confident that other startups will not be able to easily replicate this system?
Tomita:
Yes. Nowadays, AI allows people to quickly replicate existing apps, but this is different from creating something that doesn’t yet exist. It’s still quite difficult to simply ask AI to deliver something entirely new. We are proud to have an engineering team with a strong ability to do just that.
Furthermore, by meticulously building up and analyzing user feedback and data, our retention rate is continuing to improve month after month.
Sugihara:
That rate has recently started to stabilize for you, hasn’t it?
Tomita:
Typically, B2C services suffer from continuously declining retention rates, but in our case, the decline firmly stops after about six months. Proving that we are reaching the right target audience indicates that we are approaching product-market fit. But beyond the technical standpoint, I believe we’ve created an app that parents find genuinely useful through high-quality UX and overall branding.
Sugihara:
I can see how balancing serious technological skill with a user-centric design reflects your role as an overall producer, President Tomita.
