Fomo has acquired the proprietary software and intellectual property of on-chain data firm Mobula for $17 million, bringing founder Sacha Marcus, CTO Sacha Delhoux, and Head of Infrastructure Cyril Conan into its engineering organization. CEO Paul Erlanger confirmed the transaction to Axios Pro on August 31, and Fomo said the deal will help it build more on-chain data and global infrastructure capabilities internally rather than depend on multiple external providers. Mobula’s technology already powered key parts of Fomo’s stack, including real-time APIs and security-enriched data endpoints used for scam detection and social discovery, supporting trending token feeds, cross-chain search, and WebSocket discovery with filters that blocked tokens showing bundler holdings above 15%, sniper concentration above 10%, developer wallet retention above 20%, or liquidity below $20,000. Mobula will continue operating independently while Fomo takes control of the core intellectual property and engineering leadership. The purchase follows sharp growth that has strained infrastructure, including an August 30 outage that disrupted cross-chain trading. Fomo now has more than 1.9 million users—more than double its early-July total—adds over 30,000 users daily, and saw 1.2 million users trade or interact in August, climbing as high as No. 3 in the U.S. iPhone App Store Finance category ahead of Cash App and reaching a record 107,000 daily traders on August 25 per Dune data. Monthly volume rose from $500 million in June to $1.5 billion in July and was on pace for $2.8 billion in August, while last week Fomo recorded an all-time high of $1.06 billion in weekly trading volume, including $356.56 million from Solana. Monthly revenue is running at roughly $17 million, implying an annualized run rate above $200 million. Fomo Web now generates about 25% of platform volume, Fomo Perpetuals continues to grow, and the Clans feature launched in August as competition with Pump.fun intensified around SocialFi and memecoin trading. Backers include Index Ventures, which led a $75 million Series B in June 2026 at a $550 million valuation, alongside Union Square Ventures and Benchmark, with Fomo holding a 46% share of Solana trading platform spot volume.
