Better every day.

We build, acquire, and grow performance sports apps. From cycling to running to golf. We own them. We run them. That's the difference.

Arkipel is a portfolio of apps for people who take their sport seriously. Cycling. Running. Golf. Different disciplines, same belief: consistency beats intensity, and good tools help people stick with it.

Same playbook.
Different sports.

Central team. Shared infrastructure. Ten years of lessons that compound.

We know what works: the coaching models, the retention loops, the growth experiments that actually move the needle.

It's why we built Ren in five months. A complete running app.

Earned,
not bought.

Podcasts, content, and communities. We reach athletes where they already are.

We create our own media and partner with the voices athletes trust. That's how JOIN became the go-to cycling app in the Netherlands.
