Same mission. A new chapter.
For over 10 years, we’ve put young athletes at the centre of what we build. Now we’re taking that experience into a new generation of apps to support their progress, season after season.
Where we've been
Tonsser began in football, giving young players a place to record their performances, share their progress and get noticed. With Tonsser United, we took that ambition onto the pitch: bringing unsigned players together to compete against leading academies and showcase their talent in front of clubs and scouts. It gave players outside the academy system another route to opportunity and brought us closer to the athletes we build for.

What changed
We saw an opportunity to help young athletes take greater ownership of their development. As more of their sporting lives could be captured in data, AI offered a way to turn those experiences into useful reflections and next steps. That led us to build a new product, grounded in 10 years of learning, designed for the next 10. Grinta is the first step.

What we're building
We’re building companions that help young athletes make sense of each game and training session, set their own goals and see their progress across a season. Grinta brings that approach to football, with a new basketball product on the way. We're also building something new for basketball.
