Our vision · building software in 2026

From rough idea to working software. In days.

You used to have to plan everything up front: a thick specification, weeks of analysis, months of building. Today you simply tell us your idea. With the latest AI tools and our experience, a first version you can actually click through is ready within hours or days. Then we build on it together.

Tell us your idea   How it works
Hours. to a first prototype
Days. to something you really use
0 specs. a good conversation is enough
Change course? any time, no drama
Then and now

Building software has changed. For good.

The old way

  • First a specification of dozens of pages
  • Weeks of analysis and meetings
  • Months of waiting for a first demo
  • Changed your mind? Extra work, extra cost, delays
  • Only at the end do you see what you actually get

Now, at j-consulting

  • A few sentences, a sketch or an example is enough
  • One good conversation instead of weeks of analysis
  • A first version in hours or days
  • Changed your mind? That's just the next round
  • From day one you click through your own software
How it works

Four steps. No spec.

01

Tell us your idea

Rough is fine. What should it do, for whom, and why? A few sentences, a doodle on a napkin or an app you saw elsewhere: that's enough to start.

02

We build, fast

With the latest AI tools and our experience, we turn your idea into a first working version. Not a sketch on paper: real software.

03

You click and steer

You try it yourself. What's good stays. What could be better, we adjust. Changed your mind? No problem: that's exactly the point.

04

Live, and beyond

Once it's right, it goes live: as a website, web app or installable app. And if your idea grows? Then we simply keep building.

Precise or vague

Whatever idea you have, it works.

🎯

You know exactly what you want

All the better. The more detailed your idea, the faster the result: sometimes the first version is almost the final one.

💡

You only have a vague idea

Perfect. We build something to look at, and discover together what you really need. Seeing beats reading.

🔄

You change your mind along the way

That's allowed. Because building is so fast, changing course is no longer a disaster, just the next step.

Why big software packages don't work

Pay for 100%. Use 10%.

Big software packages have to work for everyone: the accountant and the warehouse worker, the multinational and the one-person business. So they contain everything. Hundreds of menus, buttons and settings, for needs that aren't yours. The result: most users need only a fraction, and get lost in the rest.

💸

Expensive

You pay licences for the whole package, per user, year after year. Including everything you never touch.

🧭

Confusing

Screens full of options for other profiles. Hunting for that one button, taking training courses, and still making mistakes.

🧩

You adapt to it

You work the way the software wants, not the way your business works. With spreadsheets and workarounds on the side.

Keep it simple.

Now that building software has become so fast and affordable, we argue for the opposite: step away from the big package, and get software made that is 100% tailored to your needs. Only the screens you need, in your words, in the order you work. Nothing extra. And when your business grows? Your software simply grows with it.

  • Only what you use — no hundreds of features you never touch
  • Instantly clear — whoever opens it gets it, no training needed
  • Your way of working — the software follows your business, not the other way round
Tell us what you really need
Fast, not sloppy

AI writes fast. We make sure it's right.

AI is a powerful tool, but tools alone don't build a good house. Behind every project are years of experience with enterprise software for government and industry. We decide what's good enough, and what isn't.

  • An experienced developer at the wheel — AI does the typing, we make the decisions
  • Proven technology — fast, secure and maintainable, not an experiment
  • Privacy sorted — built with the GDPR in mind
  • Works everywhere — phone, tablet and computer, offline too where needed
  • A clear price — after a free introductory chat you know where you stand
Proof, not promises

This is how we already build.

Nieuw jasje Fresh look From a dated website to a fresh, fast site: usually within one week. Pie Tracker Pie Tracker A custom app for partners: log hours, cash and deals in two taps, and see live how the pie is split.
FAQ

Too good to be true?

Do I need to be technical or know everything already?

No. You tell us what you want to achieve, in your own words. We translate that into software and quickly show you something to react to.

How fast is "fast"?

A first clickable version is often ready within a few hours to days. How long the finished version takes depends on the scope and on how much you still want to change along the way: usually days or weeks, not months.

What if I change my mind?

Then we adjust. Because building is so fast, a new direction no longer costs months. Changing your mind is part of the process.

What kind of software can you build?

Websites, web apps, installable apps for phone and tablet, internal tools and dashboards for your business, and educational apps. Not sure? Tell us your idea and we'll honestly tell you whether it's possible.

What does it cost?

That depends on your idea. For an app you can start with App-start at € 250 (excl. VAT): a first working version of the core of your idea within a few days. After that we work agile: you get a separate quote up front for every revision round, and we only invoice it once you approve. That way you only pay for what you really need.

Your idea

Tell us your idea. Rough is fine.

A few sentences are enough: what should it do, and for whom? Within two working days you'll hear from us, with an honest answer and a first proposal.
