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.
