Sahin Boydas is a serial entrepreneur and one of the world’s most active angel investors. Named the #1 Most Active Angel Investor of 2024 by Lenny Rachitsky’s annual report, he has backed 234+ startups across 37 markets.

Before becoming a full-time investor, Sahin founded and exited two companies. His entrepreneurial background gives him a unique perspective when evaluating founders and their businesses.

His portfolio includes household names like SpaceX, Anthropic, Scale AI, Cerebras Systems, and Kalshi, alongside early-stage bets that have grown into billion-dollar companies. With about 24% of the public portfolio now at a company value of $1B or more, his track record demonstrates the power of diversified angel investing with strong thesis-driven selection.
