Founders

Built by engineers who worked at a mining company.

Severin and Quirin Kraus founded Sachtleben Technology while working at the Sachtleben Minerals mining group. They didn't set out to build a software company — they set out to solve a measurement problem they saw every day on the job.

After running early OWL EYE® prototypes through three years of dust, vibration, shift change-overs and industrial-network reality at the mine, they decided to share what worked. Today the same system runs at 40+ industrial sites across Europe.

Every spec on this site is field-tested before it's sold — because we were the first customer.

Severin Kraus

Managing Director · Co-founder · Operations & Sales South Europe

Mathematician by training (M.Sc.) — the analytical core of the team. Runs day-to-day operations and customer projects across Southern Europe, and keeps the bridge between the mining floor and the software team. The "what does this actually have to do in a real mine?" voice in every product decision.

Quirin Kraus

Managing Director · Co-founder · Technology & Sales North Europe

Mechatronics engineer (M.Sc., university of applied sciences). Owns the software stack from sensor firmware to cloud dashboard, REST/OPC UA integrations and the SAP/ERP coupling that puts our LiDAR data into our customers' workflow. Drives technical strategy and customer projects across Northern Europe.

Our story

Digitalising bulk material — from the mine out.

OWL EYE® was born out of a simple problem: nobody knew exactly how much material moved through our own mining operations every shift — and the handful of systems on the market were fragile, inaccurate, or bound to a single sensor manufacturer.

So we built our own. Sensor-agnostic. Field-hardened. IT-driven. The result is a platform that measures volume, mass and flow across six scenarios — conveyor belts, stockpiles, trucks, bunkers, wheel-loaders and info terminals — all sharing the same dashboard and the same APIs.

Today OWL EYE® runs 24/7 at 40+ industrial sites across Europe, from sugar harvests in Germany to copper smelting in Germany, from quarries in Portugal to power plants in Croatia.

„We didn't set out to build a product. We set out to solve our own measurement problem — and decided to share the solution."

Today the platform serves mining, metallurgy, agriculture, power, cement, recycling and logistics — all from one software stack.

Our values

Honesty. Reliability. Handshake quality.

Three words that might sound old-fashioned — and that we refuse to let go. Everything we build and every project we ship is measured against them.

Honesty

We tell you what works — and just as importantly, what doesn't. If your site isn't right for LiDAR volume measurement we will say so and walk away. Every spec on this site is field-measured, not marketing-rounded.

Reliability

Our systems run in an active mining operation 24/7 — including nights, winter, rain and dust. If OWL EYE® can't take it there, we don't ship it. Predictable performance, documented interfaces, SLAs you can sign off on.

Handshake quality

Contracts matter, but a handshake matters more. From first quote to service contract we stand behind our word — as a general contractor, a technology partner, or an on-call engineering team for your IT staff.

Parent group

Part of the Sachtleben Minerals Group.

Sachtleben Technology is a technology subsidiary of the Sachtleben Minerals Group — a multi-generation mining and processing enterprise operating barite and fluorspar mines across central Europe.

That origin is our biggest asset: every sensor, every algorithm and every dashboard was first deployed inside a real mine — surrounded by dust, vibration, shift change-overs and industrial networking reality — long before it reached the first external customer.

„We eat our own dog food. Literally. Our flagship customer is our own mining operation — which is why every specification in OWL EYE® is field-tested before it's sold."

Built in a mine. Proven worldwide.
