Crypto trading app Fomo has raised $75 million in a Series B funding round led by Index Ventures, valuing the company at $550 million.

Union Square Ventures and investors like Mark Pincus and Humam Sakhnini participated. This round brings Fomo's total funding to approximately $94 million, following a $17 million Series A in 2025.

Fomo plans to expand its engineering team and pursue acquisitions. Currently, it adds around 3,500 users daily and aims to introduce features for stocks and derivatives. The app includes trader leaderboards and social sharing tools, and 68,000 users made their first crypto purchases through its Apple Pay integration, totaling $25 million.

Founded by former dYdX employees in 2025, Fomo operates noncustodially, offering greater flexibility as it seeks to be a comprehensive trading platform for blockchain assets.
