Custom software, integrations between systems, internal tools and apps — exactly what your business needs. Built with AI, that usually costs far less time and money than you'd expect: 2 days to work out what's worth building, 5 to build it. Bigger work is just as possible. Something is already running by the time I leave — not a report in a drawer.

€1,300
Two days to map your processes and systems and work out what’s worth building — using AI as a tool, not as the pitch. You get a ranked list, one small working piece on your own data, and the honest verdict if custom software isn’t the right step yet.
on site
€3,250
Five days on site: from analysis to working software — an internal tool, an integration or an app your team can use and maintain from day one.
Day rate
€650/day
For teams who want to keep building after the five days, or whose earlier software needs adjusting: individual days at a fixed day rate, with no new engagement to set up.
Introductory rate for the first 10 engagementsPrices excl. VAT.
Two days on site: watching over your shoulder to see what happens today, what data exists, and where time gets lost.
A ranked list of what's worth building — using AI where it's the fastest route and plain software where that's enough — and, if that's the honest conclusion, the advice not to build yet.
If it continues, the build phase follows: five days from analysis to working software, faster than usual because AI speeds up the build — with permissions and the data model deliberately designed from day one, not patched in afterwards.
At departure your team gets the working knowledge, running on infrastructure you own — with individual days available for anyone who wants to keep building afterwards.
A personal note
Kufu is young. I don't have a long list of clients to point you to, and I'm not going to invent one. What I do have: years spent building things and keeping them running. Seventeen years ago I started out in web hosting. That grew into Lemon Companies, building web applications and developing software — founded, grown and sold. Then I moved to the other side of the table with something entirely new: Veton, a manufacturer of EV charging stations, where I am still active today. The cloud platform and the app there are still built and maintained by me. I'd rather spend two days looking at what's actually going on in your business than try to convince you of anything upfront. If it's not a match, you just say so, and it hasn't cost you anything.

Systems that are still running today.
fig. 01 — Purchasing and stock signals
Reorder points, safety stock and an ABC breakdown calculated from my own order history — no crystal ball, just a timely signal when something is about to run out.
Needed a foundation to build on: roughly a year of order history and known lead times.
fig. 02 — Devices in the field, updated remotely
Software running unattended on remote hardware, updated on demand, with a fail-safe so a bad update can't brick the device.
fig. 03 — Automatic lead and email follow-up
Follow-up flows built in n8n, running in a self-hosted container — editable later without commissioning new custom work.
Most people who build fast with AI can't run the result in production. Most people who can run production don't build fast. Seventeen years running companies — founder of every one of them, CTO in most — and today still building and operating Veton's firmware, cloud platform, app and ERP integration. That's the other half of what Kufu delivers: permissions and a data model deliberately designed from day one, no silent failures, and software that keeps running after handover, on infrastructure that's yours.
Not every problem is a good candidate for custom software — or for AI as part of how it gets built. Too little history, a process that's about to change anyway, or simply no worthwhile result within budget — it happens. If that's the honest conclusion, you hear it in the first days, not after the engagement, and at no extra cost or separate advisory step.
