Will Villanueva
Will Villanueva is the co-founder and CEO of DELV (formerly Element Finance), a San Francisco-based decentralized finance company building fixed and variable yield markets on Ethereum. A physicist by training and former Ethereum researcher at ConsenSys, he co-founded Element Finance with Jonny Rhea in 2020 to bring fixed-rate income to DeFi. The company raised a $32M Series A in 2021 at a $320M valuation and later rebranded to DELV, whose flagship product Hyperdrive reimagines fixed and variable rate markets with an everlasting-liquidity AMM design.
DELV
DELV, formerly Element Finance, was a research-driven DeFi company that called itself 'the factory for DeFi.' Founded in 2020 by Will Villanueva and Jonny Rhea, it built open-source infrastructure for fixed- and variable-rate yield - most notably the Element Protocol, the Hyperdrive AMM, and the Council on-chain governance framework. Backed by a16z, Placeholder, and Polychain Capital with about $36.4M raised, the team pursued the idea that reliable fixed rates were essential to mainstream DeFi adoption. After a March 2025 Hyperdrive vulnerability and a conclusion that the product had not found market fit, DELV wound down operations in June 2025 with no reported loss of user funds.
