Team
Great Sales Force Partner Network
Hrvoje studied economics and international business at the University of Zagreb and earned his doctorate at WU Vienna. Over a period of almost 30 years, he has gained extensive experience and knowledge through various international leadership and management positions at Procter & Gamble. After retiring from his six-year stint as Vice President Sales in Central Europe, he now wants to share his knowledge with passionate businesses as a consultant. In his private life, Hrvoje produces excellent olive oil, travels the world with his daughters, and shoots a few (basketball) hoops every now and then.
Klaus has a very sporty approach to most topics. This probably comes from the fact that he played handball in his youth and this was his first great passion, which he also pursued professionally. For this reason, he loves challenges and especially facing them as part of a team and overcoming them successfully. Professionally, he was employed for several years in the insurance industry in Austria and Switzerland. He held different management positions in marketing, sales, business development and customer service.
Although he worked for an IT company for almost 20 years, Norbert is the opposite of an IT person. He has had “sales genes” from birth, so to speak, and is at home in the world of (digital) marketing and CRM. Before working as a management consultant and IT service provider, he held various positions as project manager, account manager, sales manager, managing director and business unit manager in an international CRM software company.

ALEXANDER MAYRHOFER
Partner
Loving his work, Alex indulges in strategic and product challenges where out of the box thinking is crucial. The more this is related to sales issues, the better. In the last 20 years he has gained extensive experience in numerous fields and industries: regional development, hospitality, the financial industry with a focus on insurance sales, public transport, the energy sector, health care, AI and many more. Apart from that? Well… all kinds of outdoor activities and movies, the latter preferably pertaining to science fiction or martial arts (= an all-time hobby). ;-).
More than 25 years of experience in leadership and management positions – including as CEO of Coca-Cola® Slovenia – within different industries such as hospitality, FMCG and consulting, make Hermann a great fit for our GSF® team. In his working life, his heart beats not exclusively, but especially, for the topic of strategic business & brand development. Since 2017, he has been building and supporting startups as co-founder, coach, and mentor. Outside of work, Hermann prefers to spend his time with his family or on ski tours.
