03 | 2024 GTL is colourful

Together for more diversity

Our team consists of a great mix of people with different characteristics and backgrounds, so that exciting personalities come together in our office every day to work together, learn from each other, cultivate friendships among colleagues and celebrate the occasional party together.

GTL is characterised by a colourful team that is both young and experienced. That unites different nations. That speaks more than seven languages. We treat each other with respect and enjoy working creatively as a team. We value and nurture this. We don't want to do without it.

Competitionline Ranking 2023

We were speechless when we received this great news! We won bronze in this year's Competitionline Ranking! GTL won a total of 23 competitions last year, an incredible success for the whole team!

We believe that the expansion of our management team has played a key role in this success. "We can discuss things more intensively and delve deeper into the competitions. At the same time, our interdisciplinary design team is a great asset. "The mix of experienced professionals and young talent is also the secret of our success. This is how we promote innovation and secure our young talent at the same time."

We would like to take this opportunity to say a big thank you to everyone involved! Without the outstanding work, creativity and passion of the competition team, this achievement would not be possible!
