Alex Atallah co-founded OpenSea with Devin Finzer in December 2017. He was the chief technology officer while the NFT marketplace grew into one of the largest in crypto.
In July 2022 he said he would leave the company at the end of the month. NFT trading volume had fallen sharply that summer. Reports differ slightly on the exact exit date. He remained a board member.
He then started OpenRouter, a unified interface to AI models from many providers. Reports place its founding in early to mid 2023. His co-founder is Louis Vichy.
In June 2025 OpenRouter raised $40 million in combined seed and Series A funding.
