Right for you if
Need a working prototype for investor pitches or demo days
Want to user-test with real people, not mockups
Internal innovator who needs to show leadership a working demo
Technical founder without time to build the prototype personally
Want real code with real logic, not a clickable mockup
Not the right fit if
Just need to prove a concept exists
→ Build Concept ($599)Need the full app with auth, APIs, and polish
→ Build Pilot ($3,499)Need a website, not an app
→ Launch packages from $349Scope boundaries
Build Demo is focused on the working prototype. It does not cover:
User authentication (see Pilot $3,499)
API integrations beyond basic (see Pilot)
Production-grade architecture or scaling
Ongoing development or maintenance
Design system or brand guidelines
