Four years ago, my co-founders and I started Together AI because we saw generative AI as a turning point for human progress. We believed this generational technology should be open and abundantly available, not controlled by a handful of companies.

Since then, we have built a full-stack AI platform for open-source AI, grounded in frontier research and delivering the fastest and most efficient inference for AI applications and agents. Today, Together AI is trusted by thousands of customers, including many of the world's fastest-growing AI companies like Cognition, Decagon, Eleven Labs, Cursor, and Suno. What began as a conviction about the future of AI has grown faster than even our most optimistic projections.

Today, I am excited to announce the next milestone in our journey with Series C funding of $800 million from an incredible group of investors including Aramco Ventures, NVIDIA, Vista Equity, General Catalyst, Emergence Capital, SE Ventures, Pegatron, Salesforce Ventures, March Capital, DTCP Growth, Lux Capital, Geodesic, PSP Partners, and others. In addition to the equity capital, we have secured commitments for over 500 MW of compute capacity to be capitalized independently by our new investors to support our expected compute growth in the coming years.

As AI systems begin to perform real intellectual labor, they are moving from occasional tools to core production infrastructure. Companies are no longer generating a handful of responses for a demo; they are deploying agents that write code, resolve customer issues, analyze documents, and automate entire workflows. As that work scales, so does the demand for inference.
