The AI model marketplace OpenRouter serves 8 million developers by providing a single API to access more than 400 different artificial intelligence providers. Stripe has finalized a deal to acquire the startup for more than $7 billion, a price that represents at least a fivefold increase over the company's $1.3 billion valuation in May. This exit occurs just 82 days after OpenRouter's last funding round and integrates a routing layer that optimizes AI spending based on model performance and availability.
Andreessen Horowitz holds a stake of more than 17% in OpenRouter and will net nearly $1.5B from the sale, while Menlo Ventures will make over $500M. The deal, which some estimates place above $8 billion, consists of a mix of cash and equity with a primary focus on stock. OpenRouter was co-founded by Alex Atallah, a former executive at NFT marketplace OpenSea.
