Manifest OS raises $60 million Series A at $750 million valuation to replace billable hours with AI-driven law firms

Manifest OS has successfully closed a $60 million Series A funding round, marking the largest investment ever for a legal tech company and bringing its valuation to $750 million. Unlike traditional legal tech companies that sell software to existing firms, Manifest OS builds its own AI-powered law firms. These firms utilize AI agents to manage client communications, legal research, document drafting, and billing, all under human supervision.

A key differentiator for Manifest OS is its business model: it replaces the traditional billable hour system with outcomes-based pricing. To support this technology, the company also recruits and trains human staff, including paralegals and legal writers, to work alongside the AI. This allows firms operating under the Manifest brand to maintain standardized pricing and service levels.

This funding round comes amidst a significant surge in legal AI investment, following massive rounds for companies like Legora and Harvey. The industry is currently shifting from experimental AI pilots toward deeply embedded infrastructure that handles core legal workflows, including contract review, compliance, and research.
