Warbler Labs is the San Francisco-based software company founded in 2020 by former Coinbase engineers Blake West and Mike Sall that builds and maintains Goldfinch, a decentralized credit protocol on Ethereum for stablecoin lending to real-world borrowers without crypto collateral, and UID (Unique Identity), a KYC/KYB-compliant on-chain identity credential. Warbler Labs is the core development team behind the Goldfinch protocol, its smart contracts, oracles, and subgraph data layer, and publishes developer documentation for building on and integrating with the protocol. The company is backed by Andreessen Horowitz (a16z), Coinbase Ventures, IDEO CoLab, Kindred Ventures, and others, and was surfaced through the a16z portfolio. Its developer surface is primarily on-chain (Solidity smart contracts, The Graph subgraph for querying protocol data, and the UID credential) rather than a hosted REST API.
