Yasin Berk Yesilyurt
Community leader, EMEA
Berlin and Istanbul
I build communities across EMEA, market by market.
Since 2016 I have been finding the people who use a tool hardest, earning their trust, and turning what they do into programs, insights and stories. I hired and directly managed community managers in 8 countries and ran meetups and hackathons from Lisbon to Istanbul.

What I do
-
Regional teams
Set market priorities, then hired and directly managed 8 regional community managers across France, Turkiye, Germany, India, China, Korea, Japan and the United States.
-
Students and campuses
Built a scouting playbook and a 3-person team across ETH Zurich, TUM, EPFL, Imperial, Oxford, Boğaziçi and METU. The team screened 10,000+ GitHub profiles and selected 50 students for starter grants.
-
Signals into decisions
Fortnightly community health reports built on social listening, surveys and power-user interviews, with recommendations presented at company all-hands. The feedback helped shift product work toward consumer-facing applications.
-
Programs that scale
Led three $1M zkIgnite grant cohorts: 72 projects funded, 87% milestone delivery, with standardised workflows across cohorts and time zones.
Now: building Kria.
An AI video editing app for iPhone, in TestFlight beta. Creators upload their footage and describe the edit they want. I build, test and ship it with AI coding agents.
