• Forget Kylie Jenner’s disputed claim, Forbes crowned the Bumble CEO the world’s youngest self-made female billionaire after she took her Tinder rival public
• Wolfe Herd was already an entrepreneur even as a university student, when she raised funds to help victims of the 2010 Gulf of Mexico BP oil spill crisis
