# Together AI raises $800M Series C at $8.3B valuation, dominates open-source AI infrastructure

> Together AI has raised an $800 million Series C at an $8.3 billion valuation, led by Aramco Ventures with participation from Vista Equity Partners, General Catalyst, Nvidia and others. The company operates as a neocloud, renting out Nvidia GPU clusters and hosting open-source AI models at scale, and it says annual bookings topped $1.15 billion last quarter. The raise is a bet on the open-source side of the market. While the biggest labs guard their weights, Together's customers, which include Cursor and Cognition, want infrastructure to run and fine-tune open models themselves. Co-founded by Vipul Ved Prakash and Stanford's Percy Liang, the company has positioned itself as the default place to do that. The valuation nearly doubling reflects how much demand there is for compute that is not locked to a single lab's API. As more companies build on open models, the picks-and-shovels layer underneath them is turning into one of the more durable businesses in AI.
