History of Derema AB

Derema AB was first founded in 2012 by Lennart Brunnberg and is still run by the founder. Already from the start, we engaged in the Berotec consultant network company to facilitate the best of work tasks and for marketing and sales of our services.


The name Derema is an abbreviation of DEsign REalisation MAnagement. It mirrors well the areas we focus our work in, without unnecessary limitations.


From the beginning, we have had a few key clients but also supported several other companies with solving problems in areas we enjoy highly working in. Many of these have been start-up companies.


Being a Partner to Berotec means following a set of rules of conduct. We are happy to comply with these and to contribute to the development of the consultancy in various ways.

From May 2020, we are the representative for Roctool in the Nordic countries.
