Schauenburg International GmbH

What Schauenburg International GmbH does

Schauenburg International GmbH is a private, family-owned strategic investment holding company headquartered in Mülheim an der Ruhr, Germany, with a secondary office in Düsseldorf. The firm operates as a strategic family equity investor, acquiring majority stakes in established industrial companies and promising technology ventures, with disclosed transaction sizes in the €5–50 million range for core portfolio investments. Through SCHAUENBURG Ventures, the company also deploys approximately €150k per deal at the early/seed stage into disruptive technologies strategically linked to the core portfolio.

The portfolio comprises twelve companies organized across six verticals: Safety (Sensidyne, OHD, Schauenburg Systems, Jannatec Technologies, Deconta), Industrial (SCHAUENBURG Industrietechnik, SCHAUENBURG Maschinen- und Anlagenbau, B&D Process Equipment, Astech), Space (mtex antenna technology gmbh, Stratosat Datacom), plus Environmental, Analytics, and Automation categories. Combined headcount is approximately 1,800 employees across three continents including Germany, the UK, the USA, China, South Africa, and Canada. Underlying technologies span gas detection and occupational safety systems, machine and plant engineering, satellite communications and antenna systems, gas chromatography and mass spectrometry instrumentation, and environmental decontamination equipment.

The business model centers on long-duration ownership of niche industrial leaders, returning capital to the family via cash flow, dividends, and selective realizations (such as the January 2026 divestiture of Markes International Group to Velaris/Battery Ventures after 12+ years of ownership). Portfolio companies sell primarily through direct enterprise sales motions into B2B industrial, safety, space, and laboratory-analytics end markets; geographic distribution is handled at the portfolio-company level. Leadership comprises CEO Florian G. Schauenburg, Co-CEO Velina Allerkamp, and CFO Aline Antweiler, supported by an M&A/portfolio management team. Active M&A is evident (deconta 2020, ENGMATEC 2019), and SCHAUENBURG Ventures provides strategic optionality into adjacent disruptive technologies.
