Concrete work, not promises

Every service — a fixed price, clear deadlines and code that stays with you.

Services

What Xo0 does

Not presentations. Systems that are already working on Monday morning.

Web applications

CRM, internal systems, client portals, mobile versions. The software adapts to your process — not the other way around.

Process automation

Invoices, orders, reports, reminders. Work that used to take hours happens by itself — and people do what actually needs a human.

Chatbots from your documents

Conversational bots trained on your policies, manuals, price lists and FAQs. They answer employees and customers 24/7 — and always cite the source.

Document handling

Invoice scanning, contract deadline tracking, search across your whole archive. Documents file themselves and remind you about deadlines.

AI where it's useful

Knowledge bases built from your documents, assistants for employee questions — run locally, your data never leaves. And if you don't need AI, I'll say so.

Integrations

I connect the systems that don't talk to each other: accounting, ERP, e-mail, warehouse, e-shop. Data gets entered once.

Device data

Sensors, dosing units, meters — signals from production equipment become reports and alerts on your phone.

Home automation

Bosch, NIBE, LG and other modern equipment — every manufacturer's app connected into one. Automate any home process from a single place.

Ownership & privacy

Sensitive data stays on your server — the AI runs locally, nothing leaves the building. You get the code: no lock-in, no third-party cloud. As it should be with patient or client data.

Two real builds

What it looks like in practice

Your whole home — in one app

A modern home is full of technology, and every manufacturer ships its own app: Bosch has one, NIBE another, LG a third. I connect everything into a single control centre — and the home starts working by itself.

Ten apps become one: heating, ventilation, lights, appliances
Automation scenes: you leave — the house switches to saving mode; you return — it's warm and waiting
Runs locally in your home — no third-party clouds, keeps working even if the internet drops

A CRM that adapts to your company

All client data in one place — and every employee sees exactly what their role needs.

Client purchases, debts, payments and latest invoices — live, on one screen
All company contacts — not just the director: managers, drivers, process people you actually work with daily

How I work

Simply. Step by step.

01

A conversation

An hour about your process: what repeats, what gets stuck, where time disappears. Free, no strings attached.
02

A proposal

Within days — a concrete plan: what I'll build, what it costs, when it works. Fixed price, no hourly surprises.
03

A working version

First version in 2–3 weeks — with your real data, not a demo. Then I improve in short iterations.
04

Upkeep

The system is monitored and updated, and grows with you. Want to take over yourself? The code and docs are yours.

Pricing

Two ways to start

Either way — a fixed price, agreed before I start. The amount depends on your company and the scope of your processes.

Fastest start

On my servers

You rent a working system — like electricity from the grid.
