Prime Intellect

Prime Intellect is an AI infrastructure company, founded in 2024, that builds a full-stack platform for training and running custom AI agents — compute access, a reinforcement-learning framework, and evaluation tools offered as modular building blocks rather than an all-or-nothing product. Its core pitch is data control: organizations can train agentic systems in-house instead of routing proprietary data through frontier labs like OpenAI or Anthropic. Customers including Ramp and Zapier use a hosted version of the tools, while teams that want deeper control can assemble the components themselves.

In July 2026, Prime Intellect raised a $130 million Series A at a $1 billion valuation, led by Radical Ventures with participation from the venture arms of Nvidia, Intel, and Dell, alongside operator-angels including Aravind Srinivas of Perplexity, Aaron Levie of Box, and Winston Weinberg of Harvey. The company positions itself around building what it calls an open superintelligence stack.
