Prime Intellect raises $130M Series A at $1B valuation for enterprise AI agents

Prime Intellect, founded in 2024, has raised a $130 million Series A at a $1 billion valuation to help enterprises build AI agents without relying on frontier labs like OpenAI or Anthropic. The round was led by Radical Ventures, with participation from Nvidia Ventures, Intel Capital, Dell Technologies Capital, Iconiq, and notable angel investors including Aravind Srinivas (Perplexity), Aaron Levie (Box), Winston Weinberg (Harvey), Jeff Wang (Cognition), and Brendan Foody (Mercor). The startup provides a full stack for agentic AI development: compute access, a reinforcement learning framework, and evaluation tools, all offered modularly via a marketplace model. This lets companies pick only what they need while avoiding vendor lock-in. CEO Vincent Weisser argues that it should not be just a few labs in San Francisco who can train frontier models—every enterprise should have that capability.

The approach has already attracted major customers, including Ramp, Zapier, and Flapping Airplanes, propelling Prime Intellect to an annualized revenue run rate of $100 million. Ramp used the platform to build an agent that could find answers inside spreadsheets; according to Ramp's co-founder Karim Atiyeh, the result beat frontier models on accuracy while running faster and at a fraction of the cost. The company's growth is also fueled by enterprises' growing wariness of sharing proprietary data with closed labs like OpenAI and Anthropic, and of depending on models that could be suddenly discontinued (e.g., Anthropic's Fable). Radical Ventures partner David Katz noted that Prime Intellect uniquely stitches together the capabilities of a top-tier AI lab as a one-stop shop, making it affordable for companies to own their own enterprise intelligence. Prime Intellect's platform essentially allows organizations to become their own AI lab, iteratively refining models for specific business tasks using reinforcement learning techniques.
