Custom software, built for one company: yours

Software should fit your company. Not the other way around.

Let's look at what slows your company down. You'll usually see a working model of the fix before you commit.

The first meeting is free.

Same orders. Two ways of working.

Today 0 finished re-typed by hand in batches Receive Prepare Send With custom software 0 finished connected automated optimized Receive Prepare Send

Connected, automated, optimized:
custom software for every slow step.
An example, not client data.

No software should have to serve thousands of companies. Not in this age.

AI agents now do the building, so software made only for you is within reach.

Problems

Sound familiar?

"Our experts spend an hour on what should take minutes."

Done in minutes. Your expert still decides.

"We send out parts that turn out not to be needed."

Send only what is needed.

"Someone reads these reports by hand every morning."

Read automatically, changes flagged.

"We can't send our documents to a cloud AI."

AI that runs on your own servers.

"We don't know if our schedule is the best one."

Compare plans before changing anything.

"We only see what happened after it's over."

See it live, and act in time.

How we start

You see it before you decide.

  1. 1

    Talk

    We meet about your specific problem.

  2. 2

    Model

    A quick simulation of how it runs today.

  3. 3

    Prototype

    A small working version on a sample of your data.

  4. 4

    Decide

    We agree how to proceed. Start small, then grow.

A small, anonymized sample of your data is enough to start.

Book the first meeting

How it's built

An expert leads. AI agents build.

Your problem How things run today
  1. I decide what is worth building
  2. My AI agents write the code and the tests
  3. I review every change until it meets my standard
Your software Built for your company alone

Nothing ships unreviewed

Every change is tested, and it ships only when I am satisfied with it.

The simple answer wins

If a simple solution does the job, I will say so.

You own it

The code and documentation are yours. I maintain it, or teach your team to.

Work

Problems I have worked on

Product, live

InterFact

It began as one city's problem: trains blocking crossings, and nobody could say how often or for how long. Solar-powered cameras and AI now detect every blockage and show it live.

Delivered

A car manufacturer

Supplier shipment data is checked automatically, so errors are caught before they reach the production line.

Delivered

A jewelry manufacturer

The production steps for thousands of ring models are planned automatically, each with the right machine and setting.

In pilot

A food ingredient manufacturer

Blend recipes took up to an hour each by hand. Now a whole order takes minutes.

Analysis and prototype

A field service company

A quarter of shipped devices came back unused. I prototyped a daily planning tool to cut that.

Prototype

A purchasing team

Price files and bulletins were read by hand. Now they are read automatically, into one view.

Simulation

A facility management company

Twelve today-versus-optimized scenarios across staffing, kitchens and laundry.

Feasibility study

A manufacturer with strict data rules

No cloud AI allowed. I measured how well AI on their own hardware reads their documents.

Questions

Common questions

What is custom software?

Software built for one company: yours. No software should have to serve thousands of companies. Not in this age. So it is built for you, the way a tailored suit is made to your measurements, and it is yours. Some call it bespoke or tailor-made software.

How much does custom software cost?

It depends on the problem, so I don't quote before I understand it. The first meeting is free, and you'll usually see a working model before you commit. We start with one small piece and grow from what works.

How long does it take?

A first prototype can be ready in just a few days, sometimes in a few hours. The full tool depends on its size, but it usually takes a few weeks.

Do I have to share my company's data?

A small, anonymized sample is enough to start. Nothing sensitive has to leave your company for us to find out whether this is worth doing.

Is software built by AI agents reliable?

The agents write the code and the tests. I review every change, and nothing reaches you until it meets my standard. Behind that review are more than 15 years of building software in industry, and teaching and researching software engineering as a professor. I answer for the result.

Who owns the software, and who maintains it?

You own the code and the documentation. Afterwards I can maintain it for you, or teach your team to.

Can the AI run on our own servers?

Yes. For companies that can't send documents to a cloud service, I measure how well AI running on your own hardware does the job before recommending it.

Will it work with the systems we already have?

Yes. Connecting to what you already use is usually part of the job, whether that is an ERP, spreadsheets or files that arrive by email. I start by reading from those systems, so nothing you rely on changes until you are ready.

What if off-the-shelf software would do the job?

Then I will tell you. I check whether something simpler already solves the problem before building anything, and the first meeting costs you nothing either way.

What's slowing your company down?

The first meeting is free.
