s multi-billion-dollar pursuit of AI model marketplace startup OpenRouter isn re seeing a gigantic surge in demand. The company says it has over 10 million users. OpenRouter Andreessen Horowitz and Menlo Ventures are poised to turn investments made less than two years ago into payouts worth nearly $2 billion combined if Stripe acquires the AI model marketplace for more than $8 billion, according to people familiar with the matter. A16z, whose investment was led by former general partner Anjney Midha, owns more than 17% of OpenRouter, according to people familiar with the matter. The firm spent around just $20 million to get this stake, having first invested in the seed round last year.
