Manifest OS Secures $60M in Series A Funding to Build AI-Native Legal Infrastructure

$60M just walked into legal tech and didn’t ask for permission. It asked for change. Manifest OS raised a Series A at a $750M valuation, with Menlo Ventures leading and Kleiner Perkins, First Round Capital, and Quiet Capital in the mix. Legal tech has seen plenty of “innovation theater.” This feels more like the building inspector finally showed up with a sledgehammer.

Dan Mishin, Founder & CEO of Manifest OS, isn’t politely decorating the billable hour with AI confetti. He is going after the meter itself. Outcomes-based fixed pricing. Predictable costs. Less invoice fog. More actual legal work. Funny thing happens when time stops being the product: efficiency stops being a threat.

The company powers AI-native law firms under the Manifest Law brand, combining software, brand standardization, and centralized back-office infrastructure. Translation: the boring plumbing matters. Client comms, legal research, document drafting, billing, reporting, HR and recruiting integrations, all moving through an AI-native operating system with human-supervised AI agents. Lawyers still make the legal calls. The machine just stops making them hunt for the ball in the parking lot.

In 18 months, its 1st Manifest OS-powered immigration firm has handled 3,000+ client engagements, supported 150+ corporate immigration programs, and built a network of 100+ immigration attorneys and co-counsel averaging 10+ years of experience. It reviewed 5,000+ attorney applicants and accepted <1%. That is not staffing. That is selection pressure with a law degree.

The early metrics carry weight: 3x faster client response times than traditional firms and a visa approval rate 15% above national benchmarks for certain categories, based on cases decided in Q3 2025 compared with USCIS EB-1 and O-1 approval rates. No fireworks needed. Just receipts.

The sharper move is strategic. Manifest OS didn’t sell AI tools to firms built around hourly drag. It partnered with lawyers to build AI-native firms from the ground up, using Arizona’s Alternative Business Structure model to align ownership, operations, technology, and legal delivery without pretending ethics are optional garnish.

Behind the capital, the bench matters. Shawn Carolan, Partner at Menlo Ventures, stepped in to lead. Ilya Fushman, Managing Partner at Kleiner Perkins, brought that pattern-recognition energy. First Round Capital and Quiet Capital don’t show up for experiments, they show up for companies that know exactly what they’re building and why now.

If this model holds, the ripple effect is not subtle. When pricing aligns with outcomes and infrastructure replaces improvisation, the billable hour starts to look less like a standard and more like a relic that overstayed its welcome.
