[Alex Atallah Founded OpenRouter, Valued at $500 Million] Alex Atallah's AI model aggregation platform, OpenRouter, has recently gained attention. OpenRouter integrates APIs from over 500 AI models to provide developers with a unified interface, charging a 5% fee per call. The company has secured $40 million in funding led by a16z, with a valuation of $500 million. Atallah previously co-founded OpenSea, the world's largest NFT marketplace, and chose to step away during the peak of the NFT market. OpenRouter's business model is similar to OpenSea's, earning fees by aggregating decentralized supply. When Atallah registered OpenRouter in early 2023, there were almost no similar products in the market. Currently, its monthly transaction volume has grown from $800,000 to $8 million.
