Manifest OS raised a $60 million Series A at a $750 million valuation to create AI-native law firms under the Manifest Law brand, beginning with business immigration.
The company is not offering another copilot for lawyers. Instead, it intends to own the legal service layer itself: fixed-fee, outcome-based, AI-powered law firms designed for customers who want results rather than software.
How the model works
Manifest OS targets the billable-hour model. It combines an in-house AI platform, centralized back-office operations, and licensed lawyer review to automate routine legal workflows while retaining human lawyers for judgment, compliance, and edge cases.
The economic argument is straightforward: legal rates rose 7.4% in 2025, and legal help remains unaffordable for many businesses and consumers. Manifest OS’s pitch is blunt — make law firms cheaper by rebuilding them around AI from day one.
Why this could matter
Different AI strategies are emerging in the legal market. Some companies, such as Harvey, focus on making existing lawyers faster with AI tools. Manifest OS asks a tougher question: what if clients never needed to engage with a lawyer-shaped workflow at all?
If the approach succeeds, the future law firm may look less like a room filled with billable hours and more like an AI operating system with lawyers attached where the law still requires human involvement.
