HALLMANN HOLDING International Investment GmbH

What HALLMANN HOLDING International Investment GmbH does

HALLMANN HOLDING International Investment GmbH is a privately held, family-controlled Austrian diversified investment holding founded in 1995 by entrepreneur Klemens Hallmann and headquartered in Vienna. Operating under the HALLMANN CORPORATE GROUP brand and legal entity HHII Beteiligungen GmbH, the group holds assets exclusively in sole ownership without external investor participation and consolidates wholly-owned operating subsidiaries across multiple sectors.

The core operating engine is real estate: Safe Real Estate Vienna acquires and optimizes Gründerzeit apartments in Vienna's Jugendstil districts, while SÜBA AG (acquired) provides vertically integrated construction capability, together covering the full development-to-construction value chain. The entertainment vertical includes Film House Germany AG and its subsidiaries Summerstorm Entertainment and Egoli Tossell Film (acquired 2011), Hallmann Entertainment Company (founded 2018), and the Hallmann Dome multi-functional event arena (home court of BC Hallmann Vienna). Technology and life-science exposure is delivered through cyan Digital Security (network-integrated and endpoint security, 23 patents, 200+ data centers), Cybersec Invest GmbH (cybersecurity acquisition vehicle), Rejuveron Life Sciences AG (longevity biotech), and Katalysen Ventures (venture capital).

The business model is relationship-driven and B2B, with no public pricing; revenue is generated through real estate development margins and rental income, film distribution and licensing, security solution contracts with telecom and insurance customers, biotech R&D partnerships, and event-venue operations (100+ events per year). All investments are self-funded and the parent entity operates with a lean 1-10 person central team, supported by specialized contacts in corporate communications (Franz Ramerstorfer) and asset management (Anna Freundlinger).
