April Koh

April Koh is the co-founder and CEO of Spring Health, a New York-based mental health company that uses machine learning to match people to the right care instead of leaving them to trial and error. She started it as a Yale senior in 2016 after reading a research paper that suggested algorithms could outperform the average psychiatrist at picking treatments. By 2021, at 29, she became the youngest woman to lead a unicorn; by 2024 the company raised a $100M Series E at a $3.3 billion valuation, serving employers and health plans across more than 200 countries. She was a 2025 TIME100 Next cover star.
