GJM was born in 1985 as a family business in La Roca del Vallés.

During our years of expanding we have been through many different changing phases making sure that we have always followed the evolution and needs of the national market.

We first started in the Telecom Sector working for clients like Alcatel or Amper amongst others..

Later on, we concentrated in the IT Sector following the entrance in the Spanish market of HP (Spain). Fujitsu, Olivetti and IBM being our main clients. Theses companies moved their production to the Asian Market creating a migration towards local business who offered a more competitive market price.

As today, with a 90% of the total production, the automative sector is the most important market that we are still working with exporting to more of 22 worldwide countries.

During the year 2000 onwards whilst looking for reduction in costs and when many of our main clients moved to countries were they could keep their produciton at low cost. It was in 2004 that we were motivated to gain competitiveness in prices that we created a joint venture with a Romanian company which after gaining knowledge in taxing and employment law we created GJM Components SRL.

This was followed by GJM Mexico later on in 2012 searching our entrance in the American market.
