S3, E2: The Biotech Bromance: Serial CEO and Investor’s 20‑Year Journey of Building Biotechs with Steve Butts, Arrivo Bio and Dave Adair, Solas BioVentures

This episode of Raising Biotech takes a different turn — not just the story of a biotech, but of a partnership. Steve Butts, CEO of Arrivo BioVentures, and Dr. Dave Adair, Co‑Founder and Managing Partner of Solas BioVentures, have built ten companies together over nearly two decades. From Steve's first shaky startup pitch to Dave in San Francisco to major exits and a novel company‑building model, Surani explores their individual paths, their serendipitous meeting that kicked it all off, and the lessons they’ve learned along the way right up to their current venture, Arrivo BioVentures, which has raised over $100 million to be the first to tackle female depression.
