Early-stage capital for ambitious founders from Slovakia & CEE.

Backed by Slido founder
Peter Komorník.

Our Story

We built Slido in Bratislava and scaled it to millions of users worldwide, leading to its successful acquisition by Cisco in 2021.

Along the way, we grew side by side with other ambitious companies and saw what happens when startups cluster in one place.
Talent stays.
Standards rise.
More founders step in.

Traun exists to spark what comes next.

Our Approach

We've been there.

Building from zero is chaotic.
That's why we don't just invest.
Expect hands-on support across product, go-to-market and hiring.

We stay involved.

Our evergreen structure means we stay for as long as it makes sense for the company.
No pressure to rush exits.
