Don't wait weeks. Try it in days.

The team that builds the prototype can also ship the product.
Process
Short and clear.
Goals and constraints (1 day).
Intense production sprint.
Demo and feedback.
Scale / pivot / stop.
Who it's for
Founders, innovation teams and PMs who need concrete proof for leadership buy-in.
Frequently asked questions
How is this different from a Figma mock?
A mock looks right; our prototype proves the flow works — clickable with real or mock APIs.
How long?
Typically 5–15 business days; scope is intentionally narrow.
Can it become the product?
Yes. Code and design decisions are left portable to production.
One page or many screens?
Critical path (happy path) + 1–2 edge cases — learn, don't build everything.
How do we share it?
Password link, investor demo or moderated user test — format to fit.
