What Serotonin does
Serotonin is a privately held marketing firm and product studio founded in 2020 that operates as a go-to-market platform for web3, AI, and biotech companies. The firm serves blockchain protocols, DeFi projects, crypto exchanges, NFT platforms, and traditional brands entering web3, with a customer roster that includes Chainlink, Polygon, Arbitrum, Optimism, Circle, Sotheby's, Mercedes-Benz, and Pernod Ricard, among more than 75 named clients. It is headquartered remotely in the United States and was acquired by UK-based digital marketing agency Embryo in March 2026 after earlier acquiring Manchester-based agency Unparalleled in August 2025.
The company operates three proprietary web3 products: Spindl, a wallet-aware marketing analytics platform built by the team behind Facebook's original ad product; Mojito, a web3 commerce platform used for onchain digital product sales and customer retention; and Franklin, a hybrid crypto and fiat payroll platform leveraging stablecoins. These are layered on top of professional services spanning web3 marketing, strategy, research, recruiting, and legal/compliance advisory. Distribution combines direct enterprise sales with the se.ro membership NFT platform, which provides recurring subscription access to the firm's service ecosystem.
Serotonin monetizes through subscription membership fees, professional services engagements, product platform fees for Spindl/Mojito/Franklin, and promotional/rewards programs; pricing is quote-based for enterprise work and not publicly disclosed. As of August 2025, the combined Serotonin–Unparalleled entity was reported to generate over £1m in EBITDA annually, with management indicating plans to raise institutional funding. The company holds no disclosed patents, and no proprietary AI/ML capabilities are documented.
