NEW YORK, April 28, 2026 — Manifest OS has raised a $60 million Series A at a $750 million valuation to expand a model of AI-native law firms that charge fixed or outcomes-based fees. The company combines a common service brand, legal-workflow software and a central back office while licensed attorneys retain authority over advice and case decisions.

Menlo Ventures, Kleiner Perkins, First Round Capital and Quiet Capital participated in the financing. Manifest OS said the capital would support expansion beyond its initial business-immigration practice and develop the operating infrastructure used by affiliated firms.

The investment backs a service model, not just software seats

The company announcement argues that selling another productivity tool to conventional firms leaves the billable-hour incentive intact. Manifest OS instead builds technology and shared operations for firms trading under the Manifest Law brand, where pricing is tied to a defined service or outcome rather than time recorded.

That distinction separates the company from many legal-AI vendors. Manifest OS is not itself a law firm and does not provide legal advice. Legal services come from powered firms, and licensed lawyers preserve independent professional judgment.

Three components support each practice

  • a unified brand sets expectations for pricing, service quality and client experience;
  • AI-native software covers communication, collaboration, research, drafting, billing and reporting;
  • a centralized back office handles intake, staffing, training, business development, quality assurance and collections.

The first practice uses Arizona's ownership framework

Manifest OS incubated its first business-immigration firm through Arizona's Alternative Business Structure programme. The framework permits non-lawyers to hold economic interests in licensed firms under oversight by the Arizona Supreme Court and its ABS Committee.

The arrangement creates room for outside capital and technology investment without transferring legal strategy to the technology provider. Professional-conduct rules still apply, and attorneys retain exclusive control of case decisions and client advice.

Human review remains part of document production

The platform embeds human-supervised AI agents in tasks such as gathering documents, processing questionnaires, filling forms and preparing drafts. Manifest OS says every AI-generated legal document receives multiple rounds of attorney review and final sign-off before use.

That safeguard is central in immigration work, where a plausible but incorrect statement can affect a person's status or an employer's hiring plan. Automation can organise repeatable steps, but responsibility for accuracy and legal judgment remains with qualified professionals.

Eighteen months provide early operating evidence

The company reported more than 3,000 client engagements and 100+ immigration attorneys, including co-counsel, after 18 months. It also said the participating lawyers averaged more than ten years of prior experience and that fewer than 1% of more than 5,000 applicants had been accepted.

Manifest reported visa approval rates 15% above a national comparison and client response times three times faster than traditional firms. The approval comparison covered selected EB-1 and O-1 decisions during the third quarter of 2025, and the company explicitly notes that prior results do not guarantee similar outcomes.

Fixed fees change what efficiency is worth

Under hourly billing, reducing the time needed for a matter can reduce the invoice. Under fixed-fee or outcomes-based terms, the provider keeps more of the benefit when automation removes administrative work, while the client receives price certainty. Manifest OS wants that alignment to fund continuing investment in technology and operations.

The commercial risk also moves. If a matter consumes more work than expected, the firm cannot simply pass every additional hour to the client. Pricing therefore depends on good case selection, reliable workflows and early identification of exceptions.

The funding must support expansion without diluting oversight

The initial focus on business immigration offers structured forms and repeatable processes, but cases still vary in evidence and legal complexity. Moving into new jurisdictions or practice areas will require different licensing arrangements, professional rules, data controls and specialist judgment.

Investors are financing the proposition that a shared operating system can give smaller practices some scale advantages of a large firm. Success should be measured in client outcomes, transparent pricing, correction rates, attorney workload and compliance—not merely in documents processed by AI.
