“Success can be planned”
Born in Salzburg, he is one of the best sailors in Austria (6 times Austrian state champion). The sporting highlight was his participation in the 2008 Olympic Games in Beijing.
In 2009, Christian Nehammer ended his Olympic career and concentrated on his professional career in Telekom Austria Group. He used his experience in controlling and top-level sports to build the controlling department of a telecommunications provider in Belarus.
He significantly influenced the professionalisation of Telekom Austria Group’s purchasing until 2014 and led the largest and most successful cost savings project of A1 Telekom Austria (2014), for which the company received the “Procurement Excellence Award” in 2016.
As CFO of Brantner Group, he was responsible for the “modernisation” of the financial processes and also headed the IT, HR, Purchasing and Project Management departments in addition to exercising the management function and power of attorney of several Brantner Group companies. At the same time as professionalising the finance functions, Hans-Christian Nehammer implemented the legal restructuring of Brantner Group with 67 subsidiaries.
Since 2019, Hans-Christian Nehammer has been advising companies as an independent consultant on increasing efficiency and profitability.
Privately, he spends his free time with his two sons and his wife on the mountains and is still passionate about sailing.
“In management consulting, we understand the situation of each client and offer situation-specific and practical solutions. Before each order is accepted, expectations are clearly defined to avoid misunderstandings from the outset. That is the only way to establish a trusting customer relationship”.
Joachim Zimmel has more than 25 years of experience in financial and operational tasks up to management and supervisory board functions. As an expert from various functions such as Head of Controlling, CFO and General Manager, he has a proven track record in the plastics production, raw materials, telecommunications and environmental services sectors. His professional experience extends to internationally implemented projects, such as the support of companies in the start-up phase or the necessary financial restructuring management. He also acts as an investor in the fields of PR, IT, FMCG and personnel services and familiar with the different perspectives of both sides of the negotiating table, from small businesses to large corporations. Since 2009, Joachim Zimmel has also been teaching at the Lauder Business School (Vienna) in the field of “project financing” and was awarded the professional title of Prof. (FH) in 2016.
Robert Kohl contributes to Christian Nehammer’s expertise by providing the technical infrastructure, operational controlling and investment calculations for the clients served.
“Controlling needs good financial systems. I set them up, operate them and then implement them at and with the client. Good financial systems and plausible investment calculations may not be sexy, but with them, I pave the way to success for companies,” Robert Kohl is convinced. The data provided is the basis for smart decisions.”
His path led the Styrian and business graduate from Forum Stadtpark to the controlling department of A1, where he met Christian Nehammer and Petra Wolkenstein, the founder of the boutique management consultancy Konsultori. Years later, Kohl and Nehammer deepened their cooperation at Brantner Walter GmbH, where they ensured the professionalisation of the finance functions. In his last position, Robert Kohl led the Treasury, Group Controlling and Controlling Systems departments at Brantner Umweltgruppe GmbH.
