About us

So production pays off again.

We make sure manufacturing companies always know what their work actually costs and whether they're on target — because no one can run a business well on a number that's only approximate.

Where we come from

2021

The question

At the Institute of Production Engineering and Machine Tools (IFW) at Leibniz University Hannover, researchers studied how reliable operational data actually is in mid-sized contract manufacturers. Sixteen companies, one sobering result.

2019–2022

The answer

A research project develops a method that derives what's actually happening in production from machine and localization data — without anyone entering anything by hand.

2022

The founding

The method became a product, and the product became a company.

Today

In active use

Three contract manufacturers, more than 50 machines, more than 1 million events processed — including in aerospace and machinery/plant engineering.

Market & Sales

Studied mechanical engineering and industrial engineering at TU Braunschweig, then worked in PLC programming and project management in renewable energy. Went on to research capacity-oriented production planning and fine-scheduling of machining processes based on machine data at IFW Hannover. Later led operations in the aerospace sector.

During my time as plant manager, reliable data was scarce. A lot was captured, almost none of it connected. Searching and waiting were part of daily work. I still made decisions — just from gut instinct. That works, often — and you never notice when it didn't. That's exactly what I wanted to stop doing.

Technology & Software

Studied mechatronics and mechanical engineering at Leibniz University Hannover, then worked as a research associate at the Industry 4.0 Competence Center, followed by the project "Localization and Communication System for Concurrent Manufacturing Planning and Control" at IFW Hannover.

I worked with machine data early on. Getting access was never the problem. The problem was that a signal alone means nothing: it says a spindle was running, not for which order or at what cost. That link was always made after the fact — from reports and memory, exactly when it's worth the least. The question never let go of me: why not connect the data right where it's generated?

How we think

Most vendors come from one direction: from software, from consulting, or from mechanical engineering. We know all three. The problem we solve sits exactly in between.

The shop floor

We've worked in production companies, not just read about them. We know why bookings get batched at the end of a shift, and why nobody fills out a form that gives them nothing back.

The IT

Grown system landscapes, aging controllers, an ERP with fifteen years of customizations. We build for reality, not the ideal case.

The research

Two dissertations and a study across sixteen companies, before the first line of code existed. We measured the problem before we solved it.

First, we get more out of what's already there. Digitalization isn't an end in itself. We don't digitalize everything — only what makes a decision better. So the first step is almost always the same: getting more out of the data your business is already generating. Only after that do we talk about anything new.

And everything depends on one condition: the data has to be correct. That's our actual job.

We're at home anywhere from the shop floor to the balance sheet. Honestly, though — if we had to choose, we'd choose the shop floor.

Knowledge transfer isn't a bonus. It's the requirement.

Software alone doesn't change a business. Deciding based on data and running paperless production is a way of working, not an installation. It only takes hold once the people in your business understand where a number comes from and why it's correct. That's why we pass on what we know. What's in our dissertations and research projects doesn't stay in the publications — it reaches your people: on the shop floor, in the office, in production planning. We want to enable businesses.
