Anthropic Forms New Enterprise AI Services Company with Blackstone, Hellman & Friedman, and Goldman Sachs
Anthropic has announced the formation of a new AI services company co-founded with Blackstone, Hellman & Friedman, and Goldman Sachs, backed by a consortium including General Atlantic, Apollo Global Management, GIC, and Sequoia Capital. The firm will deploy Claude into core operations of mid-sized enterprises—community banks, manufacturers, regional health systems—using embedded Applied AI engineers from Anthropic alongside the new company's own engineering staff. The venture extends Anthropic's existing Claude Partner Network (which includes Accenture, Deloitte, and PwC) by targeting a market segment that lacks in-house resources for frontier AI deployments. This represents a significant structural move by Anthropic to capture enterprise deployment revenue through a dedicated services vehicle rather than purely through API licensing.
