A trading app called Fomo just raised $75 million at a $550 million valuation, and the investor list reads like a who’s-who of people who normally wouldn’t touch a memecoin with a ten-foot pole.

Index Ventures led the Series B round, with Union Square Ventures also participating. The angel investor roster includes Zynga co-founder Mark Pincus, Discord CEO Humam Sakhnini, and Eventbrite co-founder Kevin Hartz.

From $19M to $75M in months

Fomo launched its app in May 2025, then raised a $17 million Series A led by Benchmark in November 2025. Total funding before this round sat at roughly $19 million, including a small pre-seed investment.

Fomo reports approximately 3,500 daily new users and claims rapid revenue and trading volume growth.
