How it works
From kickoff
to store
Four phases, fixed scope per sprint, and a build you can open on your own device from week one.
Scope
Week 1One week to pressure-test the idea. We map the user flows, cut the fat, and agree on what version one actually is.
Design
Week 2–3Clickable prototypes before a line of production code. You feel the product early, so surprises stay cheap.
Build
Week 4–10Two-week sprints with a live staging build from day one. You watch it come together, not a status report.
Ship & Scale
OngoingStore submission, analytics, monitoring and a roadmap. We stay on to grow it, or hand over clean.
