The story
Arnaud
Even after a few triathlons, I still wake up at night wondering what I forgot — especially early in the season.

So we built this app that removes that stress, once and for all.

And honestly… seeing this little capybara tell me it's all good cracks me up 😂

Several triathlons under my belt, a club around me — and I still forget something on race day.

Beyond the training, racing a triathlon takes serious organisation!

Especially with all the travel that comes with racing.
