This is a 0→1 opportunity with direct commercial stakes and real user impact.

Bachelor’s degree or equivalent practical work experience.
You've helped scale a B2B product from Series A to Series C and want to do it again. You thrive taking ambiguous problems from zero to a working product in users' hands. You want direct ownership over a commercial product with real revenue implications.
You prefer a defined roadmap over building one from scratch. You're not comfortable working closely with AI tools and systems as core product components. You need clear separation between PM work and commercial strategy
AI-driven legal platform with fixed fees
Manifest OS builds AI-powered legal technology that acts as an operating system for modern law firms, delivering fixed-fee, outcome-driven services through its Manifest Law brand for individuals and American businesses, starting with high-volume immigration and expanding to corporate law. It works by embedding AI-native tools into the legal workflow to automate repetitive tasks and assist with complex document creation, while giving clients real-time case status and timelines. It differentiates itself by using Arizona ABS to allow non-lawyer ownership and heavy tech investment, plus a platform-first approach that scales across practice areas with transparent pricing. Its goal is to make high-quality legal representation more accessible by reducing operational overhead, offering predictable pricing, and delivering consistent outcomes.
