Whitney Wolfe Herd — Bumble ($1.6 Billion IPO)

Whitney Wolfe Herd co-founded Tinder at 24, then sued the company for sexual harassment. She used the settlement to build Bumble, a dating app where women message first, reaching 100 million users by 2020. She went public in 2021 at age 31, the youngest woman to lead an NYSE IPO, with a valuation of $7.7 billion—giving her a $1.6 billion stake on day one. This personal wealth is 75% cheaper than the typical $7.7 billion IPO value, outpacing #3 Rihanna's $1.4 billion fortune. She turned harassment into a masterclass, building a better app worth billions.
