Manifest OS, a New York-based startup building AI-native law firms, has closed a $60 million Series A at a $750 million valuation, the company announced on April 28. Backers include Menlo Ventures, Kleiner Perkins, First Round Capital, and Quiet Capital. Manifest is pitching the round as the largest Series A in legal technology history and the clearest sign yet that investors believe AI will rewire how legal services are delivered, not just how lawyers draft documents.
A Different Bet on Legal AI
Most well-funded legal AI startups, from Harvey to Eudia, sell software into existing law firms. Manifest is doing something different: it builds and operates its own law firms under a unified "Manifest Law" brand, with AI baked into every workflow. The first firm launched roughly 18 months ago under Arizona's alternative business structure (ABS) program, which allows non-lawyers to own legal practices. It currently specializes in business immigration, and the new capital will fund expansion into global immigration services.
Founder and CEO Dan Mishin, an immigrant entrepreneur who has spoken about spending tens of thousands of dollars on his own US citizenship paperwork, frames the company's mission as ending the billable hour. Manifest's platform combines AI agents for client communications, attorney-client collaboration, research, document drafting, reporting, and billing with centralized back-office operations and fixed-fee pricing.
Why The Billable Hour Is The Target
Mishin argues the hourly billing model is structurally misaligned with both clients and lawyers. He cites figures suggesting roughly 80% of American businesses and consumers cannot afford legal services when they need them, even as billing rates rose an average of 7.4% in 2025. "To truly shift the market to outcomes-based pricing and to democratize access to high-quality legal services for clients, we needed to rethink the entire business model of a law firm from the ground up," Mishin said.
Quiet Capital's Michael Bloch echoed the thesis from the investor side, framing the bigger opportunity as "using AI to provide and power better legal services directly" rather than just selling productivity tools to incumbent firms.
The Series A Size Debate
Manifest is positioning the raise as the biggest Series A ever in legal tech. Reporting from Legal IT Insider notes that Eudia raised a $105 million Series A last year, but argues much of that was contingent on Eudia closing acquisitions, with $30 million committed upfront and the remaining $75 million tied to M&A. By that measure, Manifest's $60 million in upfront capital is the largest fully committed Series A the sector has seen.
Implications
The deal lands in a quarter where legal AI valuations have already pushed into the multi-billion-dollar range and where ABS regulatory experiments in Arizona and Utah are increasingly being used as testbeds for AI-native firm models. If Manifest's outcomes-based pricing works at scale, it would put pressure on traditional firms whose economics still depend on billing time rather than delivering results — and would validate a path where AI funding flows not to software vendors selling into law firms, but to operators replacing them.
