Semantic Solutions.

Our skills. Relying on technologies.

Cognizone is a company founded in 2015 by a team of IT engineers of many disciplines who work on Computer Science and Information Technology for the last 15 to 25 years.

We help organizations and businesses maximize their unique set of data by providing IT and Data Management services with a focus on Semantic Technologies, Linked (and Open) Data, Metadata, Thesauri and Controlled Vocabulary Management.

Since 2015, we engaged in 15+ projects on Legislative open data, open data in the Labour Market and Semantic Interoperability. We successfully implemented deliverables in big government and industrial projects like CELLAR, EUROVOC, ESCO, EUROPASS2, Legi4LUX and Legi4CH. [more info about our projects in this article]

We want to stay driven by innovation.

The world moves on, technology follows closely and we want to “taste” AI, especially on the implementation level. To this end, we want to further foster its adoption within the company.

We want to grow, in a careful and structured manner and focus even more on strengthening our corporate culture, which we believe is one of the strongest keys to success.

We are so far financially independent and we want to continue being that, not neglecting though potential investors.

How we work

We use all leading technologies with a particular focus across typescript, angular, spring boot, semantic web and much more to develop the best software.

Every day we stand to build better tools to help your data making meaning and sharing its knowledge while focusing on your return on investment (not your expenses).

And we are proud to assert our reliability, craftsmanship, and good humour.

Over the years, we successfully implemented industrial-strength solutions for a wide range of clients – from private companies to public stakeholders.
