A gym software built by people who ran a gym.
Kasratbook started as a hack in a single-branch gym. Today it runs the day-to-day of hundreds of them.
In 2023, we opened a small gym in Pune. Within three months, we were drowning — not in members (there weren't many yet) but in the admin. Three spreadsheets, two WhatsApp groups, a payment link for each member, and a biometric device that exported to a CSV nobody could parse.
We tried the existing software. It was slow, ugly, and clearly designed by people who had never stood behind a front desk. So we built our own — nights and weekends at first, then full-time when other gym owners started asking if they could use it too.
Three years later, Kasratbook runs 500+ gyms across India. It's still built by people who spend time on the gym floor. It still prioritises the owner and their team over any fancy feature. And we still hate slow software.
Four principles. Every decision passes through them.
Built on a gym floor.
We started Kasratbook because we ran a gym and hated the software we had to use. Every decision is still made with owners in the room.
Fast, or don't ship it.
Every screen in Kasratbook is engineered for speed. If a page feels slow in beta, it doesn't ship. Full stop.
Owners first, always.
Members matter. But it's owners who bet on us. We prioritise their workflows, their margins, their peace of mind.
Boring, not buzzword.
No crypto, no AI gimmicks, no metaverse. Kasratbook does the unsexy work of running a gym — well.
