The Hellenic Corporation of Assets and Participations (HCAP/Growthfund) announce the new management of TIF – HELEXPO
HCAP/Growthfund announces the appointment of a new Chair, Chief Executive Officer and new members of the Board of Directors of TIF–HELEXPO, as well as the establishment of an Advisory Committee that will represent Thessaloniki’s key stakeholders and support the work of the Board. In this way, effectiveness is enhanced, corporate governance is strengthened, and support for the company’s strategy is broadened. A genuine commitment to serving the city, extensive experience and expertise, and a successful professional and social track record are common characteristics shared by all members of the Board of Directors. For them, TIF – HELEXPO is not only associated with Thessaloniki as one of its most important landmarks but also reflects a broader national identity and historical continuity as an institution.
The new Board of Directors will be supported by a seven-member Advisory Committee which, by representing the voice of the city, will contribute its know-how and experience to shaping directions and supporting critical initiatives, such as the launch of the forthcoming redevelopment project – an historic objective for TIF–HELEXPO and for the city itself.
The Board of Directors of HCAP/Growthfund appoints Mr. Christos Tsentemeidis as the new Non-Executive Chair of TIF- HELEXPO. Mr. Tsentemeidis combines many years of senior management experience in international companies such as Johnson & Johnson and P&G and has served several important organizations with integrity and success, including ECR Hellas, a key institutional forum for the industry and retail sectors. For many years he was a member of its Board of Directors and served as Co-Chair, working alongside distinguished entrepreneurs and senior executives of the Greek market. He has extensive experience with a strong focus on customer experience management and has led business operations in several Balkan countries as well as in Greece. His origin from Northern Greece and the fact that he has lived with his family in Thessaloniki for the past 20 years further enhance his ability to understand the needs and prospects of the city.
HCAP’s management extends its sincere thanks to Mr. Tasos Tzikas for his long-standing contribution to TIF–HELEXPO. Since 2011 he served the organization, initially as CEO and, from 2013, as Chair. Through his steady presence, as the longest-serving Chair of the company, he made a decisive contribution to its continuity and extroversion, leaving a significant imprint and a legacy both on the institution and on the city of Thessaloniki. His tenure was characterized by stability and consistency and played a key role in setting the redevelopment project in motion.
The Board of Directors of HCAP appoints Mr. Andreas Mavrommatis as the new Chief Executive Officer of TIF–HELEXPO. The new CEO has many years of international experience at the core of the global exhibitions industry and a deep understanding of the sector’s commercial strategy. Since 2013 he has held senior roles at Informa PLC, the world’s largest exhibitions organizer, with full P&L responsibility for high-value international businesses. This experience provides him with a strong competitive advantage in attracting, developing and creating large, internationally recognized exhibition brands and will support the expansion of activities and the dynamic utilization of infrastructure in Greece and abroad. With experience in the Olympic and Paralympic Games, he manages complex environments and international partnerships. As part of assuming his duties, he will reside permanently in Thessaloniki, ensuring a strong connection with the city and the TIF–HELEXPO ecosystem.
HCAP’s management also expresses its sincere thanks to Dr. Kyriakos Pozrikidis for his long and substantial contribution to TIF–HELEXPO. Through his work and vision, he added value to exhibition events and established TIF–HELEXPO as a key pillar of Greek and European exhibition activity. His long-standing participation on the Board of Directors of the Global Association of the Exhibition Industry (UFI), as well as his re-election for a third term as President of the Central European Fairs Alliance (CEFA), confirm the broad recognition and trust of the European exhibition community in him. It is noted that Dr. Pozrikidis will remain as an Advisor to TIF–HELEXPO to support the new management in its complex mission.
