Manifest OS, an artificial intelligence-powered legal technology company building infrastructure for AI-native law firms, has raised $60 million in Series A funding to accelerate the expansion of its platform and support its mission of transforming how legal services are delivered. The financing values the company at $750 million and represents one of the largest Series A rounds announced in the legal technology sector.

The Series A round was led by Menlo Ventures, with participation from Kleiner Perkins, First Round Capital, and Quiet Capital. The investment will support Manifest OS as it develops its AI-powered legal operating system, expands its network of lawyers, and builds technology designed to improve access to legal services for businesses and consumers.

Founded by Dan Mishin, Manifest OS is developing a platform designed to power AI-native law firms through a combination of artificial intelligence software, centralized operations, and technology-enabled legal workflows. The company aims to create a new model for legal service delivery by moving away from traditional hourly billing structures and toward outcomes-based pricing and predictable service quality.

Manifest OS operates by providing lawyers with AI-powered software tools intended to improve efficiency, increase productivity, and help legal professionals serve more clients. The company’s platform supports lawyers through technology designed to automate operational tasks, streamline workflows, and provide infrastructure for a modern legal practice.

The company’s latest funding comes as artificial intelligence continues to reshape professional services industries. Legal technology has become one of the fastest-growing areas for AI adoption as law firms and legal professionals seek tools that can reduce administrative work, improve research capabilities, and make legal services more accessible.

Manifest OS has positioned itself as more than a software provider by building a model that combines technology with a network of legal professionals. The company works with lawyers who use its software platform to operate under the Manifest brand, providing access to AI tools and operational support intended to improve the economics of legal practice.

The participation of Menlo Ventures highlights growing investor interest in AI applications that address large professional markets. Menlo Ventures has invested in technology companies across enterprise software, consumer technology, and artificial intelligence, and its leadership of Manifest OS’s Series A reflects confidence in the company’s approach to modernizing legal services.

Kleiner Perkins joined the round as a key investor, bringing additional venture capital support from a firm known for backing technology companies across software, consumer platforms, and emerging technology categories. Its investment adds further momentum to Manifest OS’s efforts to develop AI infrastructure for the legal sector.

The involvement of First Round Capital and Quiet Capital further strengthens the company’s investor base as Manifest OS works to scale its platform. Both firms have supported early-stage technology companies and participated in the company’s Series A financing alongside Menlo Ventures and Kleiner Perkins.

Manifest OS’s funding arrives at a time when businesses and individuals are increasingly looking for alternatives to traditional legal service models. High legal costs, limited access to attorneys, and time-consuming administrative processes have created demand for technology solutions that can improve efficiency while maintaining legal expertise.

The company is initially focused on immigration law and has plans to expand into additional legal practice areas. By combining AI software with a network of attorneys, Manifest OS aims to create a scalable legal services model capable of serving a broader range of customers.

The startup’s founder, Dan Mishin, has said that his personal experience navigating the U.S. immigration system influenced the company’s mission to make legal services more accessible. Manifest OS seeks to address inefficiencies in the legal industry by using artificial intelligence to support attorneys and improve the client experience.

With its $60 million Series A investment from Menlo Ventures, Kleiner Perkins, First Round Capital, and Quiet Capital, Manifest OS plans to continue expanding its AI-native legal platform and advancing its vision for a technology-driven legal services ecosystem. The company is positioning itself at the intersection of artificial intelligence and law, aiming to redefine how legal professionals operate and how clients access legal support.
