Manifest Raises $60 Million in Largest Legal AI Funding Round

Manifest OS closed a $60 million Series A, the largest funding round ever for a legal tech company, valuing the startup at $750 million. The company builds AI-powered law firms that operate on outcomes-based pricing instead of billable hours.

The platform handles client communications, attorney collaboration, legal research, document drafting, reporting and billing through AI agents supervised by humans. Manifest also recruits and trains paralegals, administrative staff and legal writers to work alongside the technology.

Firms using Manifest operate under a unified brand with standardized pricing and service levels. The approach differs from competitors who sell software to existing law firms-Manifest partners directly with lawyers to build new practices around AI from the start.

"We made the hard choice to not sell our AI software to existing law firms who are often beholden to billing customers more hours as a means to better compensation," said Dan Mishin, Manifest's founder and CEO.

Competitive Funding Surge in Legal AI

Manifest's round reflects a broader wave of investment in legal technology. Legora raised $550 million at a $5.6 billion valuation last month, while Harvey secured $200 million at an $11 billion valuation in March for its contract analysis and compliance tools.

Legal AI is moving from experimental pilots to embedded infrastructure in law firms, handling research, contract review, compliance and billing tasks. The sector is consolidating around companies that become essential to how lawyers actually work.
