The venture studio of Esad Kılıç and Burhan Kocabıyık. We build our own products first, then stand beside founders who have proven monthly revenue.
We work from our Rotterdam base on three pillars. The third is the network on the map.
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.
We look at customers, not decks. We work with founders generating €10,000 or more in monthly revenue.
DOA, our community of 1,700+ paying Turkish founders across Turkey, Germany and Europe, lets us see founders early.
Companies we take from idea to product to revenue with our own team. GOAT, PrototipAL and our Mac apps were born this way.
Studio portfolio ↓We work with founders at €10,000+ monthly revenue on scaling, distribution and capital. Applications go straight to the founders, and we reply within 48 hours.
