Manifest OS

Manifest OS is a New York-based startup building the operating system for AI-native law firms, combining a unified brand (Manifest Law), an AI platform that automates client communications, document drafting and legal workflows, and a centralized back office for paralegals and admin staff. The company partners with attorneys to launch firms that use fixed-fee and outcomes-based pricing instead of the billable hour, starting with U.S. business immigration under Arizona's Alternative Business Structure programme. It plans to expand the model into global immigration and additional legal practice areas.
