Well, I'd say they are also 1st tier in France, Austria, Switzerland, Spain, Japan, China, the Netherlands, and Eastern Europe (incl. Russia). Certainly not in the UK and in the US. Also not in Latin America where they only have one office in Sao Paulo. Furthermore, they are not represented in South East Asia / Australia.
However, they are growing strongly in China and Japan, also in the Middle East (Bahrein)..
