Fomo has raised $75 million in a Series B round led by Index Ventures, with backing from Union Square Ventures, Zynga co-founder Mark Pincus, Discord CEO Humam Sakhnini and Eventbrite co-founder Kevin Hartz, giving the crypto trading startup a $550 million valuation. The company was founded in 2025 by former dYdX team members Paul Erlanger, Se Yong Park and Prashan Dharmasena. The funding highlights investor interest in non-custodial trading apps, where users retain control of their assets rather than placing them with a platform.
