About

From the Westerwald. For Europe.

GTensor GmbH is an IT and AI consultancy for companies in Germany and Europe. One team that advises, builds and runs.

Who we are

GTensor GmbH was founded in 2022 in Hilgert in the Westerwald and is based in Dernbach today. We are an IT and AI consultancy: we advise companies on software, cloud and AI, and we build and run what we recommend.

Our clients get one team for the whole path, from the first assessment to a system in production. No handover between a strategy firm and a separate supplier.

Our AI tools are our own: GTensor develops and owns the GT AI Platform and GT Code AI, so we can fix, extend and support them directly. In consulting we stay vendor-neutral and recommend what fits your situation.

About the name: GTensor is short for GreenTensor. A tensor is the data structure at the heart of modern AI.

Our story

AI is not new to us.

We did not start with chatbots. Our work began with classic machine learning, long before large language models made headlines.

  1. The beginning

    Machine learning and deep learning

    We started with convolutional neural networks (CNNs) for image and visual data, and recurrent networks (RNNs, LSTMs) for time-series data. That is where we learned the hard parts early: clean data, reliable training pipelines and models that hold up in production.

  2. Early 2022

    Our own language model

    Months before ChatGPT made language models a household name, we began working with natural language models and built our own fine-tuned version.

  3. Today

    LLMs, agents and our own tools

    Today we build with large language models, AI agents and retrieval over company data. This experience goes into our own tools, the GT AI Platform, GT Code AI and our voice call agents, and into every client project.

Every generation of AI brings its own pitfalls. We have worked through several of them. That is what clients and partners get from us: judgment about what really works in production.

Principles

How we work

  • Working software over slides

    We show progress as something you can click, not as a report.

  • Plain language

    We explain technical decisions so that everyone at the table can follow them.

  • Own technology

    We develop and own our AI tools, so we can fix and improve them ourselves.
