Product engineering for sport & fitness
Own the platform your fitness business runs on.
We build the apps and back offices behind fitness brands that have outgrown rented software. We moved UN1T’s 10+ location franchise onto a platform they own, and we co-founded Jimmy Coach. Two founders in every engagement. Your code from the first commit.

01
Real fitness products, not promises.
Who we build for
Built for founders who take their product seriously.
You are not looking for cheap hands. You want a team that understands what you are building and can be trusted with the part of your business your members actually touch.
Multi-location operators
Studios, gyms, and franchises where memberships, bookings, and payments simply have to work.
Founders shipping the real thing
Sport and fitness founders building a product members depend on, not a prototype to demo.
Coaching apps that scale
Coaching and creator-led products going from a handful of clients to thousands.
02
One team for the whole product, not just the easy parts.
01
Member & booking platforms
Subscriptions, payments, scheduling, and the back office that runs every location.
02
Sport & fitness apps
iOS and Android products your members open every day. Fast, and built to last.
03
Community & social features
Chat, groups, and the engagement layer that keeps athletes coming back.
04
AI inside your product
Personalized coaching, smart recommendations, and assistants built into real workflows, not bolted on.
Delivered by a senior team that works alongside yours, or as a fixed-scope build with a clear timeline and price.
03
You work with the people who built it.
Most agencies put a senior on the sales call and juniors on your project. With Gimmir, the founders are in the room from the first call to delivery.
Two founders who have already built what you are trying to build, plus the team behind them.
04
Why founders trust us with the real thing.
01
Senior from first call to delivery
The founders are in every engagement. No bait and switch.
02
You own everything, day one
Code, IP, and accounts. Always yours.
03
A senior team, already formed
People we have shipped with before, led by the founders. You don’t lose a quarter hiring.
04
We push back
If a decision will hurt your product later, we say so. You pay for judgment, not just hands.
05
Start with a conversation, not a contract.
One path, three steps. You decide how far you go, and nothing is locked in.
