About us

Do you know any athletes who are among the best in the world in all sports? It’s not likely. And what is true for athletes also applies to recruitment consultants. After all, nobody can have detailed knowledge in many industries simultaneously, be on the cutting edge of developments and also be able to draw on an extensive and in-depth candidate network. That is why we deliberately focus exclusively on the energy sector. And in all modesty, we really know what we’re doing here. We have successfully completed more than 300 projects over the past seven years. The experience we have gained from this and our network greatly accelerates the search for candidates: While others are still trying to understand the task, we are already delivering the first results.

 

As helpful as knowledge of the industry and a great candidate network are however, they do not replace the need for the curious listener. After all, the decisive factor is often hidden behind what is obvious. This applies to the task presented by our clients as well as to the selection of candidates. We are well aware of our responsibility to our clients in this regard. Our pursuit of excellence extends to all the process steps in our consulting projects and serves only one purpose: finding the best candidates and rather than the second best. Maximum discretion and confidentiality as well as great sensitivity in dealing with candidates and companies are a matter of course for us.
