Yasin Berk Yesilyurt
Community leader, EMEA
Berlin and Istanbul
I build communities across EMEA, market by market.
Since 2017 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 built and managed community managers in 8 countries and ran meetups and hackathons from Lisbon to Istanbul.
Where I have built communities.
Tap a city.
Austin, Mexico City, Lisbon, Marrakech, Oxford, London, Paris, Geneva, Lausanne, Berlin, Budapest, Krakow, Belgrade, Istanbul, Ankara, Bangkok, Singapore.

Signals into decisions
A biweekly community health report built on social listening, surveys and power-user interviews, presented at company all-hands.

Programs that scale
Led zkIgnite, a $1M grants program: 72 projects funded across three cohorts, 87% milestone delivery.
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.
