Together AI’s latest funding round has brought in $800 million, pushing the company’s valuation to $8.3 billion. This surge reflects investor confidence in the firm’s focus on providing open-source AI hosting and inference solutions, seen as crucial bottlenecks in the AI industry’s expansion.
Founded in 2022, Together AI specializes in enabling businesses to train and deploy AI models using open-source frameworks such as DeepSeek, MiniMax, Kimi, and Nemotron. Its recent round was led by Aramco Ventures and included major investors like Vista Equity Partners, General Catalyst, Emergence Capital, NVIDIA, March Capital, Pegatron, and S Ventures.
The company has shifted its emphasis toward AI inference — the runtime operation of trained models — recognizing a growing market for more affordable, flexible alternatives to closed proprietary systems. This approach has propelled Together AI's annual bookings beyond $1.15 billion, with the use of open-source AI models tripling industry-wide over the past year.
Together AI highlighted that clients experience significant cost reductions, reporting savings between six- and sixty-fold compared to proprietary AI solutions, often with comparable or improved performance. In just over two years, the company’s valuation has skyrocketed from $1.25 billion in early 2024 to more than six times higher today.
Looking ahead, Together AI plans to expand its computing power and infrastructure about 50-fold within five years to support growing demand. This investment underscores a broader shift in the AI sector toward building cheaper, scalable open-source infrastructure, a trend echoed by investors who identify AI infrastructure as a major area for future development.
