Prototype in five days

1,800 EUR, fixed

In five working days you get something that runs, not a picture of it.

One flow of your product, built, deployed on a domain and handed over. You use it, you send the link to other people, and then you decide whether the real thing is worth building.

Five working days, 1,800 EUR, half on start

You usually get here after one of these

03

The question is never whether it can be built.

01

There is a design and no answer

A Figma, maybe a deck. What there is not is one person outside the building who has used the thing and said whether they want it.

02

The quote was three months and twenty thousand

Both numbers may well be right. Neither of them can be justified before you know whether anyone wants it.

03

Someone wants to see it next month

An investor, a partner, your first ten customers. A recording of a prototype is not the same thing as a link they can open on their own phone.

What arrives on Friday

Four things, and a link that works.

01

One flow, working end to end

Not a set of screens that look right and do nothing. One path through the product, with real data that gets saved and comes back.

02

On a domain, behind a link

You send a link. People use it on their own phone, without you on a call explaining what they are looking at.

03

It looks like a product

I came into this through design. A prototype that looks provisional gets judged as provisional, and that is the wrong thing to find out from the people you are testing on.

04

A written answer about what comes after

What holds, what would have to be rewritten, and roughly what the real version costs. One page, at the end, whether or not you continue with me.

How five days is possible

I build it with AI.

This page ships 5 KB of JavaScript

Five days is not a sales number, it is what the work takes now. I decide what gets built, in what order, and what it looks like. The implementation is written with AI. I test it, and I am the one who answers for it.

That is the whole reason the price is 1,800 and not twelve thousand, and the reason one person can hand you a working product in a week. Writing the code stopped being the expensive part. Knowing what to build, in what order, and what breaks later is still the expensive part, and that is the part you are paying for.

This site was built the same way: fourteen pages in two languages, five kilobytes of JavaScript, and a script that checks every page for unreadable text and sideways overflow before anything goes out. You are reading the method, not a description of it.

Before you order it

Not production

A prototype is not a product.

  • No real money. Payments, if the idea has them, run in test mode.
  • No load. It holds you and the people you show it to, not a launch.
  • No edge cases. The path through works. Most of the ways around it do not.
  • If you continue, parts of it get rewritten. That is normal, and it is a great deal cheaper than finding out in month three.

If what you need is the real thing, with real payments and real users, that is a project with phases and a different price. Say so in the first message and we skip this page.

The week

You see a working link at the end of every day.

The week

  1. MonScope, then buildLink
  2. TueBuildLink
  3. WedBuildLink
  4. ThuBuildLink
  5. FriYour changes, handoverLink
A link that works at the end of every day, not only on Friday.
  1. 01

    Morning of day one

    Half a day, on a call and then in writing, cutting the idea down to what fits in the days that are left. You decide what stays in. I tell you what will not fit.

  2. 02

    Days one to four

    It gets built. At the end of each day there is a link that works, so you are never waiting until Friday to find out what you are getting.

  3. 03

    Day five

    You use it and tell me what is wrong. I change what fits in the day. Then it is handed over: domain, accounts and code in your name.

The whole price

1,800 EUR

Five working days

Ask for a week

Half on start, half on handover.

  • The domain, the accounts and the code are in your name from the first day.
  • The 1,800 is not deducted from a later project. You are not buying a document, you are keeping something that runs.
  • If I cannot cut your idea down to five days, I tell you that before you pay, and I say what it would take instead.

Write me one paragraph about what you want to see working, and I will tell you whether it fits in five days.

Write to me

Answered the same working day, in writing. If it does not fit, I say what does.
