Manifest OS Raises $60M at $750M Valuation — AI-Native Law Firm OS Replaces Billable Hours with Fixed Fees Under Arizona ABS

PYMNTS·medium signal

Manifest OS closed a $60M Series A (Menlo, Kleiner Perkins, First Round) at $750M valuation for what it calls the world's first AI-native law firm model. Instead of selling software TO law firms, Manifest operates its own network of affiliated attorneys using AI to deliver legal services at fixed fees — directly attacking the billable hour model. Starting with immigration law under Arizona's Alternative Business Structure program, expanding to tax. This is vertical SaaS disruption taken to its logical extreme: don't sell tools to the industry, BECOME the industry with AI at the core.
