Sentr started as a side project with two friends: a way to track our amateur team’s stats, and turn them into fantasy points.

We couldn’t find an app that did it, so we built one.

Starting lean

Three of us, in our spare time, building only what our users really needed. Our MVP found around 150 teams logging matches every week.

The beta

In 2024 we raised £30k to build a beta that works the same on web, iOS and Android. I designed it, and managed the build with our CTO and an external team.

Growth

We launched in September 2024 with no marketing budget. Network effects did the rest: every team that logs a match brings in its players.
