Companies with a Polish founder rarely look Polish on paper. YC files each startup under its US address, so its own directory shows almost no Poles. Count by founders and family roots instead and this directory finds 40 YC companies, with 2026 the record year at 8. Airbnb and ShipBob are included for their founders' Polish heritage. Beyond YC, Polish-born co-founders stand behind OpenAI, Snowflake, ICEYE and ElevenLabs, and people with Polish family roots helped build Apple and ran YouTube
