A small studio that takes an idea all the way to the app store. Strategy, design, engineering and launch, handled by the same people from the first sketch to the first download.
Most ideas die between the deck and the download. We close that gap. One team owns the whole journey, builds with modern AI tooling to move fast, and holds the line on quality so the thing that ships is the thing you'd be proud to put your name on.
Both are live today. Both were designed around one real audience and the thing they actually need, not a feature list.
Live
The family community app. Meet parents down the street, plan playdates your kids will beg to repeat, and discover local activities. It's built from day one so no one can identify your child.
Live
A dating app for people who'd rather meet doing something they love. Say something before you match, find people nearby who like the same things, then go do it together, at whatever pace is yours.
Launch site for the family app: features, child-safety standards, and plans for local businesses.
Visit →A photo-led site for the dating app. How it works, where it's open, and the safety promises in plain words.
Visit →The studio's home on the web. You're on it now, and we built it in-house like everything else.

I started Tosemum because the apps I wanted for my own life didn't exist yet. I wanted a safe way to meet the family two streets over, and a kinder way to meet someone than swiping. So we build small, ship real, and keep every promise that's on the page.Tosemum Holdings · a small independent studio, founded 2026
Four stages, the same small team all the way through. Nothing gets lost in a handoff because there isn't one.
Who is this for, and what do they actually need done? We answer that on paper before anyone writes code.
Every screen is sketched, argued over and approved before it's built. It's cheaper to change a drawing.
AI-accelerated development with production discipline. Every change is reviewed, tested on a real phone, then committed.
Store submission, release, and then the part most people skip: listening to the first users and fixing what they find.
Product thinking, UX, engineering and release managed as one pipeline, from wireframe to launch, so nothing falls through a handoff.
We build with modern AI tooling, turning months of development into focused weeks without trading away production quality.
Architecture, technical direction and delivery guidance for teams turning an idea into shipped software, grounded in a decade of big-tech delivery.
Native apps live on Google Play, built to production standards and store-compliant from day one, with iOS on the way.
Partnerships, consulting, or just hello. We read everything and reply to all of it.
