Prototype development: from idea to clickable in days
A fixed-price sprint that turns a concept into a working prototype you can test on real people.
The fastest way to find out whether an idea holds is to put it in front of someone. A prototype is far cheaper than a build and answers most of the questions a build would have answered expensively.
Founders raising against a demo, and product teams deciding between two directions.
What Prototype Lab does.
Fixed price and fixed length
You know the cost and the date before it starts.
Clickable, not a slide deck
Something a user can be handed without explanation.
Real data where it matters
Enough to make the test honest rather than a demo of happy paths.
User testing included
Sessions run and written up, so the result is evidence.
A go or no-go
Ending with a recommendation, including when that is “don’t build it”.
What you get that you didn’t last time.
UK-based senior team
You deal directly with the people building your product — same time zone, no quality lottery from anonymous offshore subcontractors.
Transparent pricing
Indicative ranges up front and a fixed-scope proposal after discovery. You always know what you are paying for.
One team, idea to scale
Strategy, design, build and infrastructure under one roof — one accountable team from first sketch to launch and beyond.
You own the code
All source, designs and IP transfer to you, in clean documented repositories. You are never locked in.
Things we shipped.
Every project below ran through the same four steps.
Other products and tools.
Can we see it before committing?
Yes. Ask for a walkthrough and we will show you the actual product rather than a slide deck, including the parts that are still rough.
Is it hosted, or do we run it?
Either. We host it for you on our managed infrastructure, or deploy it into your own cloud if that suits your compliance position better.
Can it be changed to fit how we work?
That is usually the point. These start as a working core and get shaped to the business — which is faster and cheaper than building from nothing, and fits better than something boxed.
Who owns the data?
You do, and you can export all of it at any time. UK-hosted by default.
What does it cost?
It depends on how much configuration you need, so we scope it first and give you a fixed number. The conversation and the scoping are free.
What is a software prototype?
A prototype is a clickable, realistic version of a product idea that people can try before any real code is written. It lets you test demand, show investors and spot problems cheaply. Devute's Prototype Lab builds one in a fixed-price sprint.
