Serena Williams reveals how her tennis mindset drives her venture investing success, backing 16 unicorns through StarFire Ventures while prioritizing underrepresented founders. The tennis legend discusses rebranding from Serena Ventures, her strategic approach to health-tech investments like Ro, and how she balances entrepreneurship, motherhood, and a sporadic return to professional tennis. Serena's portfolio is 70% women and underrepresented founders not through philanthropy but because her team opens doors others overlook, and these companies are outperforming expectations.
