About us.
Meet our team
We build tools that make ATM maintenance easier.
At diagATM, we bring together deep experience in the ATM industry and in-house software development to create practical tools for service technicians. Our compact team includes developers, testers and product experts who know what it’s like to be out in the field and what it takes to get a machine up and running quickly.
Founder Guido Walther has worked in the ATM business for over 30 years and knows the operational and technical challenges of service from the inside out. With diagPRO, we aim to simplify diagnostics, reduce repeat service calls and give technicians the tools they need to work efficiently and independently.
Your time matters to us. Your service matters to us. Our software helps you make the most of both.
A practical solution to a real problem.
When an ATM goes down, every second counts. You want quick answers, accurate diagnostics, and tools that don’t require hours of training. That’s exactly what we’re building.
At diagATM, we know the pressure that comes with ATM servicing, because we’ve lived it. We design our software to make diagnostics simpler, faster, and more accessible, so your machines can be back online with minimal delay. And because ATM availability drives your business, our job is to make sure nothing stands in the way.
What we believe
Simple, effective software
Great software doesn’t need to be complex. It just needs to work. We build tools that are intuitive and reliable, even under pressure.
Real
Collaboration
We work closely with our customers because better results come from shared experience, clear communication and mutual respect.
Continious improvement
We don’t stop at launch. We’re always learning from feedback, adding new features, and improving usability.
We listen first, then build
Every product update starts with one simple question: what do our customers need most?
