👤
Senior🎓
Top SchoolRyan Stellar is a healthcare technology executive and founder with 12 years of experience building and scaling startups that blend clinical insight, product-led growth, and AI-driven automation. As CEO of Standard Care/Retkan and former VP at Enzyme, he has driven consistent 10% monthly ARR growth, expanded enterprise footprints with customers like Genentech and Pfizer, and helped multiple companies reach strategic exits. He pairs hands-on engineering chops—from building HIPAA-compliant platforms and HL7 ETL pipelines to founding an FDA-cleared medical device—with operator experience that produced a 98.7% student placement rate at Hack Reactor. An active investor and M&A advisor in digital medicine, Ryan has guided five healthcare deals and writes small checks to mission-driven founders each year. West Coast–based with East Coast roots, he combines clinician-level empathy (years in cardiac cath labs) with product and go-to-market rigor to move clinical AI from prototype to regulated, revenue-generating deployments.
