Venture studio · Rotterdam

We build AI companies and back the Turkish founders already making theirs work.

The venture studio of Esad Kılıç and Burhan Kocabıyık. We build our own products first, then stand beside founders who have proven monthly revenue.

01 · Approach

We build first, then we partner.

We work from our Rotterdam base on three pillars. The third is the network on the map.

i.

We are operators.

We built ARspar and sold it to Floorplanner. Today we build and run our own AI products. Every piece of advice we give founders comes from something we tested in our own companies.

ii.

We select on revenue.

We look at customers, not decks. We work with founders generating €10,000 or more in monthly revenue.

iii.
1,700+Paid founder community

We have our own network.

DOA, our community of 1,700+ paying Turkish founders across Turkey, Germany and Europe, lets us see founders early.

Path A · Studio

Companies we take from idea to product to revenue with our own team. GOAT, PrototipAL and our Mac apps were born this way.

Two founders, one team.

Esad Kılıç and Burhan Kocabıyık founded ARspar together in 2020. In May 2024 it was acquired by Rotterdam-based Floorplanner.

Since then they have built every company together, including PrototipAL, DOA and GOAT. Both were named to MT/Sprout's "25 under 25" in 2022.
