About us

All about ESTeam

Who we are, where we come from, where we are heading, and who will lead us there.


The Company

ESTeam AB is a European software company founded in 1995 to develop and market language technology software. The company is registered in Sweden, headquartered in Berlin, and has its core development team in Athens.

ESTeam has provided software and services for LangOps and cross-border interoperability. We are a long-standing software provider to EU organizations and blue-chip companies. ESTeam is actively involved in ground-breaking innovation projects in the fields of NLP and AI.

Our vision is to enable communication between companies and customers, and organizations and citizens, no matter which language they use.

Our mission is to make the processing of textual data language-agnostic. We achieve this by data interoperability through semantic information infrastructures and multilingual search.

Our Origin

ESTeam was founded to solve a translation problem for Thomson Reuters. All their foreign IP data resources had to be understandable in English. Tens of millions of words should be translated on the fly in their document publishing process with less than a two minute delay. In 1997, the first five languages went live and multiple new languages were added in the coming years.

At the same time our CEO was busy building TRADOS to become a global champion. His first large contract with the EU Commission was signed and Microsoft invested in the company. He sold TRADOS in 2005 and joined ESTeam with all his knowledge in 2010. TRADOS is human user interaction, and ESTeam textual data processing for the purpose of automation. With these two backgrounds the invention of the way we do LangOps was inevitable.

Our Future

LangOps is still a novel concept. It uses new ways of organizing tasks and data, and requires a smart combination of AI, NLP, workflow, and humans-in-the-loop. We like the picture of a language factory. Like an industrial factory it consists of many standard but also some custom-made components, a content pipeline, and humans for tasks which cannot yet be automated. Firstly, everything needs to be smartly put together and then constantly be optimized by collecting and analyzing production data.

ESTeam designs, builds, and operates such language factories in a SaaS model. Sometimes we only provide consulting or deliver single machines. We deliver complete solutions in consortium with partners, who provide the humans-in-the loop.

Language factories are not yet a ready-to-deploy product. They are custom engineered to meet the content owner’s needs. Factories require a certain throughput to run efficiently. Currently ESTeam supports global companies and organizations to move to a LangOps model. Our goal is to productize the learnings and tech of every language factory deployed, thus lowering entry barriers.

ESTeam’s future is to become the preferred partner for everything LangOps.
