01
Building to find out
Teams spend months developing a feature only to discover users don't understand it. A prototype would have shown that in a week.
02 · UI/UX Design05 of 07
Clickable prototypes realistic enough to test with users, show investors and brief developers.
A prototype answers questions that documents can't: does this flow feel right, will users understand it, is this the product we want? We build interactive prototypes, from quick clickable flows to high-fidelity ones with real interactions, so you learn before you spend on development.

Sound familiar?
The problems we hear most often before someone asks us about interactive prototypes.
02
Stakeholders can't picture it
Static screens and long documents leave decision-makers guessing, so approvals stall or change late.
03
Developers fill the gaps
Without seeing how things should move and respond, developers make their own guesses, and the product feels inconsistent.
What's included
01
Prototype plan
What the prototype needs to prove, who will use it and how real it needs to feel.
02
Clickable flows
Linked screens for the key journeys, quick to change as we learn.
03
Realistic interactions
Transitions, gestures, form behaviour and states that feel like the finished product.
04
Test-ready setup
Scenarios and tasks ready for user testing, on desktop or real phones.
05
Demo version
A polished path for investor or stakeholder presentations, with talking points.
06
Developer reference
The prototype doubles as a living spec for how things should behave.
How we do it
You follow every step live in Mission Control, your project dashboard: tasks, files, approvals and a launch forecast.
- 1
Define the question
We agree what the prototype must answer, such as whether users can complete onboarding unaided.
- 2
Build
We prototype the flows at the right fidelity, from quick clickable to fully interactive.
- 3
Test
Sessions with real users, observed and recorded, to see where they hesitate or get stuck.
- 4
Iterate
We fix what testing revealed and test again, until the flow works without help.

A prototype simulates the product so you can test and demonstrate it, without real data or code behind it. An MVP is a working product with real users. Prototypes come first to make sure the MVP is right.
