Age: 28 • Cofounder and CEO, H1
Katz’s New York–based startup has online profiles of more than 10 million doctors, which are updated daily with information about the physicians’ publications, patient demographics and social media mentions. H1’s biggest business is helping more than 100 pharma, biotech and medical device companies find the perfect doc. “You’re funding billions of dollars in research every single year,” Katz says. “What if I could tell you the right doctor to run your clinical trial?” H1’s revenues were up 250% year-over-year as pharma companies scrambled to scale up large trials of Covid-19 vaccines and treatments. H1 has raised $170 million after graduating from Y Combinator in March 2020.
