Software
for Industry
Because in the end, it is never just about machines.
It is always about people.
Every line of code can become part of a machine people rely on every day.
Whether medicines are manufactured, medical products are packaged or industrial processes are controlled safely — our software often runs where reliability is not optional, but essential.
That is why we do not just develop software precisely. We develop it with responsibility.
Industries
Software for industries where responsibility matters.
What we do
From machine control to data platforms. Designed end to end.
PLC / SPS / Motion
Tailored control solutions with Beckhoff TwinCAT, Siemens TIA/S7 and Schneider Electric — from new development to optimization.
HMI & Visualization
Intuitive user interfaces in vendor systems or .NET with WPF and Blazor — performant, robust and maintainable.
MES, ERP & Databases
End-to-end data flows through ERP/MES interfaces, SQL, REST, OPC UA, MQTT and Industrial IoT.
Validated Systems
Structured software development for regulated environments with traceable documentation and clean engineering.
Connectivity
Connecting machines, lines, supervisory systems, databases and enterprise systems — secure, stable and scalable.
Support & Commissioning
Pragmatic support for commissioning, extensions, troubleshooting and long-term development.
Retrofit & Migration
Modernization of legacy Siemens S5 and S7 Classic control systems – from system assessment and migration to safe commissioning with minimal production downtime.
Selected focus
Complex projects need software that connects technology and process.
Pharma & validated production
Software for machines and systems where quality, traceability and documented processes are critical.
Packaging & line integration
Control software, HMI, interfaces and data flows for packaging machines and connected production lines.
Industrial IT & Connectivity
Bridges between controls, databases, MES, ERP and modern IT systems — robust and reliable in operation.
Trusted technology partners

Company
Engineering industrial software for machines, people and the future.
lighttree GmbH was founded in 2021. Our purpose: to make mechanical engineering simpler, more efficient and more reliable through modern software.
We combine deep know-how in automation technology, PLC programming and motion control with experience in IT and high-level software development. This enables us to bridge control systems, HMI and enterprise IT.
Our strength is not only technology, but also collaboration: we listen, think along and deliver pragmatic results — from short-term support to complete automation projects.
Career
Do you want to develop software that runs in real machines?
We are looking for people who understand machines, take responsibility and enjoy working in small, strong teams.
Software changes machines.
Responsibility changes outcomes.
Let's build both
Contact
Good software starts with a conversation.
If responsibility, precision and long-term collaboration matter to you as much as they matter to us, we should get to know each other.
