YC alumni investment platform backing tomorrow’s winners
We aim to invest in the top 10% of each YC batch
Built by YC founders, 

for YC founders
Founder Factor is an investment platform led by Y Combinator alumni investing in - and supporting - the top startups from Y Combinator, the world’s leading accelerator.

Our investing partners are accomplished YC alumni and operators. Collectively, our team has invested in more than 1,200 companies and co-founded over 100.
Human-machine selection approach
We pair a proprietary AI prediction engine with alumni diligence to validate and screen opportunities, building a diversified YC portfolio designed to outperform.

Our approach means we can move very fast.
European capital with operating reach
A large share of our capital comes from European YC alumni and leading European HNWs/founders. We open doors to EU/UK customers, hires, and partners - when you’re ready to scale beyond the U.S. We also provide warm intros to top European growth funds when it’s time to widen your cap table.
