250,000 items of equipment, 30 inspectors, three in documentation
Recording eats up the margin. You want to sell, just not to a group that turns your people into numbers.
Every year a client asks why the kettle is being tested again, and books again anyway.
We buy testing service companies for portable equipment, fixed installations and machines with 10 or more inspectors. The documentation share is high, and facility management groups push prices down. Both make automation valuable.

Recording eats up the margin. You want to sell, just not to a group that turns your people into numbers.
Your clients come back every year, but without a framework contract. You need someone who turns that into contracts.
At the repeat appointment, a third of the equipment cannot be found or is new. The test list is out of date.
Protective conductor resistance, insulation resistance and leakage current are measured quickly. Assigning them cleanly in the database takes time.
The client gets the defect list and does not respond. At the next test, the same equipment is on it again.
Many clients have no risk assessment. They expect you to set the interval, even though the employer must define it.

We look at the numbers you use to run your business yourself. The right column shows our acquisition criterion.
| Metric | What it tells us | Our benchmark |
|---|---|---|
| Number of qualified persons in the testing service | Whether your capacity holds without the owner. | We look for at least ten inspectors. |
| Repeat rate of testing clients | How loyally your clients return for the next test date. | The higher, the better. |
| Items tested per inspector day | How well routes and preparation work. | We look at the development over three years. |
| Share of clients with a digital test database | Whether the history of each device is available without paper. | We expect a fully digital test database. |
| Revenue mix portable, fixed, machines | How broad your qualifications are. | Good with shares in more than one area. |
We automate the desk work. Professional decisions and customer contact stay with your people.
This is GTP's assessment. We show it upfront so you can see what we will work with after the acquisition.
Measuring devices send values to the test lists via an interface, and a language model writes the defect descriptions.
A model plans repeat tests by site type and bundles locations into full test days.
The system calculates test days, price and framework contract automatically from the client's inventory list.
The measurement remains manual work by the qualified person, and after an accident only the signed report counts.
Your inspectors stay in the field, and the documentation roles get relief.

The multiple gives the enterprise value. What reaches your account depends on four items:
If one of these points applies, the value drops:
We calculate your value in the first call using your numbers. We go through the four items openly with you, even if the result is below your expectations.
All market data and the regulatory timeline for testing and experts
The ticket per test is small, the volume is large. Value comes from the repeat rate and documentation costs. We measure both.
We compete through lower documentation costs and a client portal. The system writes the report, the inspector checks it.
No. A qualified electrician is enough. That is why the segment depends less on individuals than certified inspection experts do.
Response usually within 72 h, indicative offer in 2 to 4 weeks, closing usually in 6 to 9 months.
Bridges, tunnels, retaining walls or noise barriers for the federal government, states, municipalities or Deutsche Bahn.
Sell a certified inspection expert firmFire protection, ventilation, smoke extraction, safety power supply or fire extinguishing systems.
Sell a hazardous substance survey firmBuilding pollutants, asbestos surveys, contaminated sites and soil protection with recurring clients.
Additional testing servicesDrinking water and legionella testing, playground and sports facility inspection.

Your clients trust inspectors with a name and recognition. That is why we only buy if the team stays and the next generation already works in the business.
We first look at who will sign in five years. If that is only the owner, we tell you before any price discussion.
Acquisition profile, teaser metrics and our commitments for all 24 segments are on a separate page. We only approach your client through you.
A 30-minute call is enough to know whether we fit. Afterwards you get a written assessment with reasons.
