Outrove is a San Francisco AI company from Y Combinator's Summer 2025 batch, founded by Egyptian entrepreneurs Saif Elhager and Ahmed ElShireef. It launched as an AI recruiter that sourced candidates and ran lifelike video and voice interviews, then pivoted to Sapien (asksapien.ai) - a platform that builds simulated populations of real people so companies, investors, and governments can test a pricing, product, campaign, or policy decision against how audiences will actually behave before committing to it.
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.
