Manifest OS has announced a $60 million Series A funding round at a reported $750 million valuation, positioning the company as one of the most closely watched new entrants in legal technology. The New York-based company says the round is the largest Series A in legal tech history and was backed by Menlo Ventures, Kleiner Perkins, First Round Capital, and Quiet Capital. The funding will support Manifest OS’s effort to scale what it describes as an AI-native law firm model built around fixed pricing, predictable quality, and a move away from the billable hour.
Challenging the Billable Hour
The company’s central argument is that traditional legal pricing has made legal services too expensive and uncertain for many businesses and individuals. Manifest OS says the billable hour rewards time spent rather than outcomes achieved, creating cost opacity for clients and administrative burdens for lawyers. Founder and CEO Dan Mishin has linked the company’s mission to his own experience navigating the U.S. immigration system as an immigrant entrepreneur, where he encountered high costs, unclear timelines, and communication gaps.
An AI-Native Law Firm Platform
Rather than selling software to existing law firms, Manifest OS is building and supporting firms that operate under the Manifest Law brand from the start. Its model combines a unified legal brand, an AI-powered operating system, and a centralized back-office structure covering functions such as intake, billing, collections, recruiting, and quality assurance. The company says this structure allows attorneys to spend more time on legal strategy and client advocacy while AI-supported workflows handle repetitive administrative and document-heavy tasks under attorney supervision.
Early Focus on Immigration
Manifest OS first applied the model in business immigration through Manifest Law, operating within Arizona’s alternative business structure program. According to the company, the first Manifest OS-powered firm has handled more than 3,000 client engagements and supported over 150 corporate immigration programs, ranging from startups to large technology companies. The firm reports working with more than 100 immigration attorneys, including co-counsel, and says its visa approval rate is 15% higher than the national average.
Investor Backing and Market Ambition
Investors are backing Manifest OS on the belief that legal services remain a large market with significant room for technology-driven restructuring. Kleiner Perkins and Menlo Ventures emphasized the company’s attempt to combine legal expertise, AI infrastructure, operational discipline, and a services model rather than simply adding AI tools to conventional firms. Manifest OS argues that many legal technology investments have focused on making traditional firms more efficient, while leaving the underlying pricing model and client experience largely unchanged.
With the new capital, Manifest OS plans to expand beyond its early immigration focus and build a broader network of AI-native legal practices. The company’s pitch is ambitious: reduce legal costs, improve transparency, maintain attorney oversight, and create a model where efficiency benefits both lawyers and clients. Its success will depend on whether it can scale that promise across practice areas while preserving legal quality, regulatory compliance, and the trust required in high-stakes professional services.
