What happens here

Strategy. Sales. Accountability.

With 150 colleagues on site, Berlin is both the group's headquarters and a fully operational location. Day-to-day operations, account management and customer support run here just as in Wolfen, Prishtina or Asunción — each location handles the engagements it leads.

What sets Berlin apart are the group-wide topics. This is where we answer questions that need more than day-to-day work: What does your service model look like in five years? Which processes are worth rebuilding with AI? How do you size your locations so quality and cost align?

As at all our locations
