The problem
Seattle-based company that needs a mobile application built to production quality at a fixed price

Seattle's tech culture sets a high bar. Amazon's app quality, Microsoft's enterprise apps — Seattle users know what good mobile software feels like.

What Seattle mobile apps require:

  • Performance that doesn't compromise — Flashlist for long lists, Reanimated for smooth animations, Expo Image for optimized loading
  • Architecture that scales — state management that doesn't become spaghetti at 50 screens
  • Native integrations done correctly — GPS, camera, push notifications implemented properly, not hacked

Process

Three steps, every time.

The same repeatable engagement on every project. No surprises, no mystery, no billable ambiguity.

01Week 0

Brief & discovery.

We send you questions, then get on a call. Output: a written scope with every step, feature, and integration listed.

02Weeks 1–N

Build & ship.

Fixed schedule, weekly reviews. No scope creep unless you change the scope — and if you do, we reprice it transparently.

03Post-launch

Warranty & retainer.

30-day warranty on every launch. Most clients stay on a monthly retainer for ongoing features and maintenance.

Why fixed-price

Why Fixed-Price Matters Here

Seattle founders know that scope creep is a cost management problem. Fixed-price prevents it.
