Zach Rosen
Zach Rosen is the co-founder and CEO of Brellium, a New York healthcare startup whose AI reads every patient chart a provider group produces, checking it against more than a thousand clinical and payor standards before a claim ever goes out. He started the company after a personal misdiagnosis cost him two years that, he learned, a few unchecked boxes in a chart could have prevented. A Berkeley Haas grad who passed through Paycom engineering, Moelis investment banking, and a first healthcare venture called Sapien, Rosen raised a $16.7M Series A in April 2025 from First Round Capital and Left Lane Capital and counts Grow Therapy, Talkiatry, Headspace, and Rula among Brellium's customers.
