Whitney Wolfe Herd — Bumble ($1.6 Billion IPO)

Wolfe Herd co-founded Tinder, then sued the company for sexual harassment at 24. She took the settlement and built Bumble — a dating app where women message first. It launched in 2014 and had 100 million users by 2020. She took Bumble public in 2021, becoming the youngest woman to take a company public on the NYSE at 31. The IPO valued Bumble at $7.7 billion. Her personal stake was worth $1.6 billion on day one. She turned being sexually harassed out of one dating app into building a better one worth billions. That's not revenge — that's a masterclass.
