An unnamed enterprise services firm backed by Anthropic, Blackstone, and Hellman & Friedman acquired San Francisco-based Fractional AI. This transaction marks the first acquisition for the new venture.

The firm helps midsize companies adopt generative AI with a focus on Anthropic’s Claude models. The parties did not disclose the financial terms of the deal.

Fractional AI will function as the central operational hub for the joint venture. The deal requires Fractional AI to terminate its 11-month partnership with OpenAI.

The firm intends to leverage its investors' networks to scale within the enterprise AI market.
