Test the idea before you fund the build
Clickable prototypes, working proofs of concept and AI demos built in days by senior designers and engineers. Put something real in front of users, investors or the board, learn fast and decide with evidence.

What we build
What Prototyping includes
Senior-owned, AI-accelerated and integrated into your stack. Everything below sits inside your monthly capacity.
Clickable prototypes
High-fidelity Figma or Framer prototypes that feel like the real product in user testing.
Working proofs of concept
Thin, real software that proves the hard part works: an integration, an algorithm, a data flow.
AI demos
Prototypes using real models on real data to show what AI can and cannot do for your use case.
User testing
Moderated and unmoderated sessions with target users, synthesised into clear recommendations.
Investor and board demos
Polished, narrative prototypes that make the vision tangible.
Path to production
Prototypes built with the production stack where sensible, so the work is not thrown away.
Process
How we run Prototyping
Capacity starts in days. Here is what the first weeks look like.
- 1
Day 1
Frame the question
Agree exactly what the prototype must prove and who needs to see it.
- 2
Days 2 to 7
Build
Design or engineering build, iterated daily with your feedback.
- 3
Week 2
Test
Sessions with real users or stakeholders, findings synthesised in writing.
- 4
End of week 2
Decide
Proceed, pivot or stop, with the evidence to justify it. Capacity rolls into the next step.
Fit
When Prototyping is the right call
You need to raise or get sign-off
A tangible demo closes the gap between a pitch and a product.
Two options, no data
Prototype both, test both, choose with evidence.
AI feasibility is unclear
A real-model prototype on your data answers the question in days.
A big build is proposed
De-risk it with a thin proof of the hardest part before committing.

Tools we use for Prototyping
We use what fits your business and your existing systems, and we say so when the answer is 'not this one'.
