Together AI raised $800 million in a Series C funding round on July 1, 2026. Aramco Ventures led the round, which valued the company at $8.3 billion. Vista Equity Partners, General Catalyst, Emergence Capital, Nvidia, Salesforce Ventures, March Capital, Pegatron, and SentinelOne's S Ventures also participated.

Together AI plans to use the funding to expand its offerings as a provider of inference. The company expects its computing capacity and infrastructure to expand approximately 50-fold over the next five years. Together AI reported annual bookings exceeding $1.15 billion in the last quarter.

Vipul Ved Prakash, CEO of Together AI, said in an interview, "The future of AI won't be owned by a few companies. It will be built by millions of developers and businesses, and open-source models are making that possible."

Together AI was founded in 2022 by Prakash, Percy Liang, and Ce Zhang. Prakash previously sold the social media search platform Topsy to Apple in 2013. The company's platform allows companies to train and run AI workloads on open models, including DeepSeek, MiniMax, and Kimi. Together AI counts Cursor, Cognition, and Decagon among its customers.

In 2023, it raised a $102.5 million Series A round led by Kleiner Perkins with participation from Nvidia and Emergence Capital.
