About

Devin Finzer is the co-founder and CEO of OpenSea, the NFT marketplace that reached a $13.3 billion valuation in January 2022 and made him and co-founder Alex Atallah the first NFT billionaires. A Brown computer science graduate who worked at Pinterest and sold his first startup, Claimdog, to Credit Karma, he pivoted a Y Combinator wifi-sharing idea into OpenSea after CryptoKitties appeared in late 2017 — then steered the company through the crypto winter, a closed SEC investigation, and the 2025 OS2 relaunch that expanded it from NFTs into all on-chain trading. He is also an angel investor in Figma, Cognition, and OpenRouter, the AI startup his old co-founder sold to Stripe for a reported $7.5 billion in August 2026.
