Alex Atallah· Co-Founder· New York, New York, United Statesin 𝕏

Alex Atallah has founded two unicorns: OpenSea, the NFT marketplace he started with Devin Finzer in Y Combinator's W18 batch that reached a $13.3 billion valuation, and OpenRouter, the AI model-routing marketplace Stripe agreed to acquire in August 2026 for a reported $7.5 billion — Stripe's largest acquisition ever. Born in Colorado to a Colombian-immigrant father, he studied computer science at Stanford and worked at Palantir before Forbes named him one of the first NFT billionaires in January 2022. He founded OpenRouter in 2023 after his Window AI browser extension convinced him AI would stay multi-model; the company grew from 4 models at launch to 400+ models and 10 million developers in three years.
