Prime Intellect raises $130M to help enterprises build custom AI agents without relying on OpenAI or Anthropic

Prime Intellect, a startup that provides computing power and specialized software tools for building AI agents, has raised $130 million in Series A funding at a $1 billion valuation. The round was led by Radical Ventures, with participation from Nvidia Ventures, Intel Capital, Dell Technologies Capital, Iconiq, and a roster of high-profile angel investors including Aravind Srinivas (Perplexity), Aaron Levie (Box), Winston Weinberg (Harvey), Jeff Wang (Cognition), and Brendan Foody (Mercor).

Why enterprises are building their own AI labs

Founded in 2024, Prime Intellect aims to give organizations the capability to train their own agentic systems without depending on frontier AI labs like OpenAI or Anthropic. While this mission would have been difficult just a few years ago, the rise of reinforcement learning techniques — which iteratively reward successful task completion and penalize errors — now allows companies to refine models for specific business tasks effectively. However, the underlying infrastructure remains so complex that most companies lack the expertise to assemble these pieces into a production-ready system.

Prime Intellect has developed what it calls a “full-stack” for AI agent development, which includes compute access, a reinforcement learning framework, and evaluation tools. The platform functions like a marketplace, providing modular access so customers can choose the specific tools they need without being locked into an all-or-nothing system.

One-stop shop for enterprise AI development

“They’ve stitched this together and built it in such a way that they’re operating at the frontier in a way that’s affordable,” said David Katz, a partner at Radical Ventures. He added that while others offer bits and pieces, Prime Intellect is unique in providing the capabilities of a top-tier AI lab as a one-stop shop for development.

The startup’s approach has attracted customers like Ramp, Zapier, and Flapping Airplanes, who pay for a hosted version of its tools. This rapid adoption has propelled the company to an annualized revenue run rate of $100 million. For example, Ramp used Prime Intellect to build an agent that helps the fintech find answers inside spreadsheets. “The result beat the frontier models on accuracy while running at faster speeds and a fraction of the cost,” Ramp’s co-founder and co-CEO Karim Atiyeh said in a statement.

Growing distrust of closed-source AI models

Another key factor driving Prime Intellect’s growth is the recent realization by companies that building on top of frontier labs carries significant risks. Companies increasingly don’t want to provide their proprietary information to OpenAI and Anthropic due to the risk of losing control over their data. They are also wary of depending on models that can be suddenly turned off, as happened with Anthropic’s Fable last month.

“How do I know that I’m not working with a company that is going to try to replace me and generalize to what I’m doing,” Katz said. “All of these things are causing people to think, ‘How do I own my own enterprise intelligence and not have these risks’.”

Prime Intellect co-founder and CEO Vincent Weisser believes enterprises are looking to move away from closed-source frontier models, and his company provides the infrastructure to make that transition possible. “It shouldn’t just be a few nerds in a glass tower in San Francisco that have the capability to train AI models,” he told Bitcoin World. “It should be every enterprise, every nation state.”

Conclusion

Prime Intellect’s $130 million Series A and $1 billion valuation reflect a broader shift in the enterprise AI landscape: companies are increasingly seeking sovereignty over their AI systems, driven by concerns about data privacy, model reliability, and long-term control. By providing a modular, full-stack platform for building custom AI agents, Prime Intellect is positioning itself as a critical infrastructure layer for the next wave of enterprise AI adoption.

FAQs

Q1: What does Prime Intellect actually do?
Prime Intellect provides a full-stack platform that includes computing power, a reinforcement learning framework, and evaluation tools, enabling enterprises to build and train their own custom AI agents without relying on closed-source frontier models from companies like OpenAI or Anthropic.

Q2: Who led the Series A round and who else participated?
The round was led by Radical Ventures, with participation from Nvidia Ventures, Intel Capital, Dell Technologies Capital, Iconiq, and notable angel investors including founders of Perplexity, Box, Harvey, Cognition, and Mercor.

Q3: Why are enterprises moving away from frontier AI labs?
Companies are increasingly concerned about data privacy risks when sharing proprietary information with closed-source providers, and about depending on models that can be suddenly discontinued. They want to own their enterprise intelligence and avoid vendor lock-in.
