Co-founded OpenSea in 2018 and was its CTO through the NFT boom, leaving in 2022. Started OpenRouter in 2023 as a single API in front of every model provider, with routing, fallbacks and usage-based billing — the layer that lets a product switch models without switching code, and one of the clearest public windows onto which models developers actually run. Raised $40M led by a16z and Menlo at a $500M valuation in 2025, then $113M at roughly $1.3B in March 2026; Stripe agreed to acquire the company in August 2026 in a deal reported above $7B.
