Stripe is reportedly preparing to acquire OpenRouter, an AI model marketplace that helps developers access and manage multiple AI systems, in a deal valued at more than $8 billion.
If the acquisition goes through, two of OpenRouter’s early investors — Andreessen Horowitz and Menlo Ventures — could turn relatively recent investments into nearly $2 billion in combined returns.
OpenRouter has grown rapidly as demand for AI models continues to increase. The platform allows developers to route requests between different AI models, monitor spending, and manage problems such as outages. The company says it now serves more than 10 million users.
The startup is led by cofounder and CEO Alex Atallah, who previously co-founded NFT marketplace OpenSea. OpenRouter announced a $113 million funding round in May that valued the company at $1.3 billion, meaning an $8 billion acquisition would represent a dramatic increase in value within only a few months.
Andreessen Horowitz, also known as A16z, reportedly owns more than 17% of OpenRouter. The venture capital firm is said to have spent roughly $20 million building that position after first investing during the company’s seed round last year.
At an $8 billion sale price, A16z’s stake could be worth close to $1.5 billion.
Menlo Ventures could also receive a substantial payout. The firm reportedly invested less than $50 million and accumulated a stake of more than 6%, which could now be worth over $500 million.
Other investors in OpenRouter include CapitalG, Sequoia Capital, ServiceNow, and Snowflake.
The potential acquisition shows how quickly the AI boom is creating enormous returns for startups and their investors. Companies that make it easier for businesses and developers to work across multiple AI models have become increasingly valuable, allowing relatively young companies to reach multibillion-dollar valuations and potential exits in just a few years.
