Serial entrepreneur David Shaikh — co-founder of Sherwood Sciences — joins the show to talk about building "impact startups," the €5.7M EU-funded app he's developing to diagnose skin neglected tropical diseases (NTDs) like leprosy and Buruli ulcer across Africa, and two decades of lessons learned from ticketing marketplaces to healthcare tech.
