I have known Sascha Harmuth for many years – first during my time as Managing Director of Mitel Deutschland GmbH, and later as CEO of Ostertag DeTeWe Holding GmbH. Our paths crossed in different roles and contexts – Sascha at the time as Sales Director of Ostertag Solutions GmbH, me as Managing Director of one of our most important technology partners. What has never changed over the years is my unreservedly positive impression of Sascha as a strong salesperson, strategic thinker, and leader of integrity.
Even during our collaboration in the partnership between Ostertag and Mitel, Sascha demonstrated a keen understanding of customer needs, technical solutions, and economic relationships. He was not only a strong salesman, but also an excellent networker who brought together internal and external stakeholders with foresight and tact. His negotiating skills, goal orientation, and ability to build sustainable business relationships contributed significantly to our joint success.
Later, within the Ostertag DeTeWe Group, I also got to know Sascha in his role as a manager. He impressed with his clarity, reliability, and ability to motivate and lead teams, even during periods of transformation. Sascha brings a rare combination of analytical strength, operational implementation skills, and genuine human touch. He sees people, recognizes potential, and creates structures in which performance can flourish.
What sets Sascha apart is his loyalty and his clear set of values. He is someone who takes responsibility, addresses uncomfortable truths, and not only plans change but implements it. I have always found him to be an honest, highly professional sparring partner who could be relied on at all times – both professionally and personally.
I recommend Sascha Harmuth without reservation – as a manager, a doer, and a person – and am available at any time for a personal reference call.
