our people

the management team and the people we work with

We are a very lean team because of our philosophy to work with our clients' people rather than bringing in lots of external people. The core team consists of Ursula Silling (Founder and CEO), Rolf Kuster (Managing Partner), Dominik Ross (Research, Event Manager, Project Manager).

Our hand picked associates are based in the UK, Spain and Italy for Europe, HongKong, Melbourne and Auckland for Asia Pacific, US & Canada for North America, Chile and Brazil for South America. 

For technology implementation we also work with developers in Ukraine and Belarus, and we do crowdsourcing projects to add extra innovation. We have included below details about a small selection of our team.
