Fomo, the New York-based social-first onchain trading app, has acquired the proprietary software and intellectual property of Mobula, an onchain data aggregation and infrastructure provider, in a deal announced on August 31. The acquisition brings Mobula's core technology and key personnel directly into Fomo's engineering ranks.

Among those joining Fomo are Mobula founder Sacha Marcus and CTO Sacha Delhoux.

What Fomo Is Buying and Why It Matters

Mobula was already powering critical parts of Fomo's infrastructure before the acquisition. Its real-time APIs and security-enriched data endpoints served as the plumbing behind Fomo's scam detection tools and social discovery features. Bringing that layer in-house rather than relying on a third-party supplier gives Fomo direct control over a dependency that sits underneath features its users depend on, such as flagging malicious tokens and surfacing trending onchain activity. For a social-first trading app where trust and speed of data are core to the product experience, owning the underlying data pipeline is a meaningful structural shift.

Mobula itself will reportedly continue to operate as an independent entity following the deal, though Fomo has absorbed its core IP and engineering leadership.

Fomo's Growth Trajectory in Context

Fomo closed a $17 million Series A led by Benchmark in November 2025, then followed up with a $75 million Series B led by Index Ventures in June 2026, landing a $550 million valuation in the process.

Fomo surpassed 1.9 million total users ahead of the acquisition, with over 1.2 million of those classified as active in August alone. The trading volume trajectory is also notable: Fomo's monthly volume jumped from $500 million in June to a projected $2.8 billion in August. The company's revenue run-rate sits at approximately $17 million, and the platform is adding more than 30,000 new users every day.

That rapid scaling helps explain the timing of the acquisition: the volume of onchain data Fomo must process, screen for scams, and serve in real time grows with each new cohort of users. How the Mobula team and technology are integrated into Fomo's product roadmap — and whether Mobula's independent operations continue unchanged — will be worth watching as the deal closes into the fall.
