Target customer

Early-adopter teams already pulling this workflow into production and willing to pay for a hosted, team-ready version

Problem-solution fit

The repo already shows strong pull around android, ffi, flutter. Packaging that pull into a hosted product reduces setup time, operational risk, and the gap between experimentation and team adoption.
