Hi, I'm Jonas — building a sports SaaS solo, in the open

Hi 👋 I'm Jonas.

CS bachelor, Entrepreneurship master. By day I'm at nono. On the side I'm building SportsFlow solo — and I'm going to write about every hard part of it out in the open. This is the intro.

What I'm building

SportsFlow replaces the thing every amateur handball coach still uses: a clipboard and a pen.

The idea is simple. Live-track every shot, assist and save during the game on a phone or tablet, and get real season analytics out the other end — shooting percentages, heatmaps, goalkeeper saves, momentum, lineup impact. Handball first, then volleyball, basketball, ice hockey.
