The approach
How it works
You bring the knowledge of your field, we bring the process and the building.
- 01
Together at the table
Half a day with your decision maker and the people who know the field. Together we choose who it is for, where they get stuck and which flow we make.
- 02
We build
Then we build a working prototype of that one flow, in your brand, with a note on every screen and the opportunities we saw along the way.
- 03
The follow-up
Half an hour together through the prototype, and what the logical next step is. No quote: you tell us whether you want to go on.
The approach
The workshop, block by block
Four hours, with a break. Everything we create stays online.

What you get
What you get
Within three working days.
A working prototype
Of one flow, in your brand, on a link of its own. Clickable on a phone or a laptop, to show around and to test.
Your core in one sentence
Who it is for, which problem it solves, what it brings in and why they choose you over the competition.
Notes and opportunities
On every screen why it is the way it is, and the opportunities we came across along the way, in a list.
A follow-up call
Half an hour to walk through the prototype and talk about what would bring the most now.
What you get
It costs you nothing but half a day
No quote up front and no obligation after. The prototype is yours, even if you do not go on with us.
What we do
- A facilitator who also builds the prototype
- All the materials, or an online board if you join remotely
- The prototype, the notes and the opportunities
- The follow-up call
What we ask of you
- A decider: the owner, a product manager, someone who can say yes
- The people who know the field, up to five or six in all
- Access to the current product, or screenshots
- Logo, colours and font
- Your top three challenges
Why free?
Honestly, we'd just really like to work on your product, and this gives us the chance. And one day shows you how we work better than any presentation.
Examples
An example: valuing cars at JP.cars
An app for car dealers to see in a few taps what a car is worth and what they can offer for it.
What's in it
- A valuation in four steps, starting from the license plate
- The current app beside it, at the flip of a switch
- A note on every screen about the choices made

Examples
Another example: the energy app
An energy manager for homes with solar panels, a battery and a charger. The app showed numbers; the household wants to know what to do.
What's in it
- What you saved this month and the best time to use power, at the top
- The power between the panels, the grid, the house, the charger and the battery in one picture
- The charger and the battery, each one tap away
