Neocloud Together AI raises $800M, leaps to $8.3B valuation Julie Bort 11:29 AM PDT · July 1, 2026 Together AI — an AI neocloud that rents out Nvidia GPU clusters and other AI-specific infrastructure — has raised an $800 million Series C at an $8.3 billion valuation, the company announced on Wednesday . The company was founded in 2022.
The round was led by Aramco Ventures, with participation from Vista Equity Partners, General Catalyst, Emergence Capital, Nvidia, March Capital, Pegatron, SentinelOne’s S Ventures, and others.
Together AI last raised a $305 million Series B at a $3.3 billion valua tion about 16 months ago. It actually came out of the gate well-funded, with a $102.5 million Series A funding round led by Kleiner Perkins with participation from Nvidia and Emergence Capital back in 2023.
There were whispers of this round back in March, when The Information reported that the company was seeking $1 billion in funding, but at a $7.5 billion valuation. If the numbers in that report were accurate, it means that Together AI took less money but perhaps got a better deal from VCs than it had been pursuing in the spring.
The hefty infusion of capital comes as Together AI claims annual bookings of over $1.15 billion as of its last quarter, as companies increasingly adopt competent yet far less expensive open source models via neocloud providers like Together AI. They are increasingly turning to this option rather than pay the premiums on tokens for closed frontier models for all their AI usage.
This has tripled usage of open source models across the industry in the past year, Together AI says, pointing to research from another company cashing in on the trend, AI gateway OpenRouter. Together AI says it has thousands of paying customers, naming Cursor, Cognition, and Decagon among them.
Neoclouds have been hot commodities for VC investment more broadly, not just Together AI. Upscale AI raised a Series A plus in an extension totaling $500 million at a $2 billion valuation last month; TensorWave — which focuses on GPU clusters from AMD — raised a $350 million Series B at $1.55 billion valuation last month as well, to name just two recent examples.
Together AI was co-founded by Vipul Ved Prakash (pictured above, middle) after he sold his previous startup, social media search platform Topsy, to Apple in 2013 for a reported $200+ million . His Together AI co-founders are Stanford professor Percy Liang (above, left) and ETH Zürich/University of Chicago associate professor Ce Zhang (above, right).
