Stani Kulechov is the founder of Aave, one of the largest and most influential decentralized lending and borrowing protocols in DeFi.
Aave
Kulechov founded the project in 2017 as ETHLend, a peer-to-peer lending platform. It rebranded to Aave (Finnish for “ghost”) in 2018 and relaunched as a liquidity pool-based lending protocol in January 2020. Aave allows users to lend and borrow a wide range of crypto assets without intermediaries, with interest rates determined algorithmically by supply and demand.
Aave pioneered flash loans — uncollateralized loans that must be borrowed and repaid within a single blockchain transaction — which became a foundational primitive in DeFi. The protocol has been deployed across multiple chains including Ethereum, Polygon, Avalanche, Arbitrum, Optimism, and Base.
By 2025, Aave was one of the largest DeFi protocols by total value locked (TVL), securing tens of billions of dollars in deposits.
Avara
Kulechov leads Avara (formerly Aave Companies), the development company behind Aave and related products including Lens Protocol, a decentralized social media infrastructure built on Polygon.
Background
Kulechov began studying law at the University of Helsinki before pivoting to blockchain development. He taught himself to code and built ETHLend while still a student, making him one of the youngest founders of a major DeFi protocol.
