Alex Atallah is Co-Founder and CEO of OpenRouter, the first and largest LLM router and marketplace, enabling developers and enterprises to access hundreds of AI models through a single unified API.

Alex studied Computer Science at Stanford University, worked as an engineer at Palantir, and co-founded OpenSea in 2018, serving as CTO and scaling it into the world's largest NFT marketplace before departing in July 2022.

A serial frontier-technology builder, Alex has a proven pattern of identifying fragmented ecosystems early and unifying them, applying the same aggregation playbook from NFTs to AI infrastructure.

After leaving OpenSea, Alex co-founded OpenRouter in 2023 alongside Louis Vichy, backed by Andreessen Horowitz, Menlo Ventures, Sequoia, and CapitalG across seed, Series A, and Series B rounds totaling over $173M.

OpenRouter has scaled to routing over 25 trillion tokens per week, surpassed $100M in annualized inference spend, serves over one million developers, and reached a valuation of $1.3B, becoming a unicorn within three years of founding.
