The Guest-One Board of Management

Oliver Maitre
Oliver Maitre

As Sales Director, this Hamburg native is always out and about seeing his customers. He develops innovative process solutions and drives sales of innovative G1 solutions.

Alongside the commercial management of the agency, organisation of fee-based customer projects is also part of his remit. Oliver Maître lives in Halle, Westphalia, and Wuppertal, and is married with two children. The BahnCard 100 railcard has been helping him to balance work and family life for quite some time.

Marcel Schettler

Marcel Schettler is also often out and about for sales purposes on behalf of Guest-One. Where there is a bigger or more complex project, he is happy to supervise this operationally from consulting, development through to implementation "on event". Where he has time on top of all that, he takes care of marketing and PR matters within the company.

The 48-year-old is married and lives with his wife, two children and now three rabbits in Wuppertal. One of his favourite quotes: "Hecticness is a sign of mental dead calm."

Thomas Kuefner
Thomas Kuefner

First and foremost Thomas Küfner is responsible for the areas of development, technology and innovation at Guest-One.

You could rightly call him the Chief Technology Officer (CTO), but he believes titles are less important than results.

With his calm and meticulous approach, when working personally on site Thomas Küfner likes to satisfy himself time and again that the process runs precisely as he planned it.
