We Keep Your Apps Running Smoothly
Since 2018, we've been helping businesses across Japan maintain their mobile applications without the headaches. No flashy promises — just solid technical support when you need it.
How We Got Here
Started in a small office in Maebashi back in 2018. The founder, Haruki Tamura, spent years watching businesses struggle with app maintenance — developers disappearing, updates breaking features, nobody answering support calls at 9 PM when something went wrong.
It wasn't supposed to be complicated. Apps need regular updates, occasional fixes, and someone who actually picks up the phone. So that's what we built. A team that treats your app like it matters because, well, it does matter to your business.
We grew slowly. Took on clients one at a time, learned what actually worked versus what sounded good in theory. By 2020, we had fifteen regular clients. Now we're at forty-three, and honestly, that feels about right. Small enough to know everyone's name, big enough to have weekend coverage.
Our average client has been with us for 3.2 years. Not because they're locked in contracts — they're not. They stay because things work.
What Drives Our Work
These aren't mission statements from a boardroom. They're the things we actually talk about during team meetings when deciding how to handle tricky situations.
Response Time Matters
We aim for under two hours during business hours. Not because it's in a contract, but because waiting around when something's broken is awful. Had a client's payment system go down on a Saturday morning in March 2025 — fixed within ninety minutes. That's just how it should be.
Honest Assessments
Sometimes the issue isn't technical. Sometimes you need a redesign, not another patch. We'll tell you. Lost a potential client last month because we said their app needed a rebuild, not maintenance. They appreciated the honesty — might come back when they're ready.
Long-Term Thinking
Quick fixes create bigger problems later. We've turned down rush jobs that would compromise quality. Had someone want a feature added in two days that needed proper testing. Said no. They found someone else, feature broke in production. Sometimes slow is faster.
Meet Someone From The Team
We're twelve people total. Here's Riku Nakajima, who handles most of the iOS work and somehow stays calm when everything's on fire.
Riku Nakajima
Senior iOS Developer
Been with us since 2019. Previously worked at a larger firm where he spent most of his time in meetings about meetings. Joined us because he wanted to actually write code again.
Specializes in Swift optimization and has this weird ability to spot memory leaks just by looking at activity logs. Clients specifically ask for him when dealing with performance issues. Also makes terrible coffee, but we've learned to live with it.
"Best part of working here? When a client's app crashes at 7 PM and you fix it by 7:45, they send you a thank you email. At my old job, you'd get a meeting scheduled to discuss why it happened. I prefer the thank you email."
Let's Talk About Your App
No sales pitch, no pressure. Just a conversation about what's working, what isn't, and whether we might be a good fit. We turn down about thirty percent of inquiries because we're not the right solution — might as well figure that out early.
