HEYM

What HEYM does

HEYM (Heym GmbH) is a family-owned German building services company headquartered in Limburg and operating continuously since 1978 under second-generation ownership, with Oliver Heym as Geschäftsführer and Christian Bapst as Prokurist. The company delivers three integrated service lines: security personnel and guard services, electronic security system installation, and building cleaning, serving industrial, commercial, trade, public-sector (banks, authorities), association/club, and private residential customers primarily in Germany.

The firm's technical backbone is an in-house NSL/AES (Notruf-Service-Leitstelle / Alarmempfangsstelle) monitoring center that handles event-driven video activation, remote video transmission, guard patrol control, and alarm transmission. HEYM's capability portfolio is anchored by a dense certification stack — ISO 9001 (held since 1997), DIN 77200, DIN EN 50518, VdS 3138, VdS 2172, DIN EN 16763, DIN 14675, and TÜV Rheinland attestation — covering quality management, alarm-receiving-center operations, and fire-alarm system standards.

HEYM distributes its offering through five German branch locations (Limburg HQ plus Lüneburg, Ronneburg, Dierdorf, and Gießen) using a direct-sales model with custom per-contract pricing. The recurring monitoring subscription layer provides a stable revenue base layered on top of project-based security-systems installation and contract cleaning work. There is no disclosed evidence of external funding, M&A activity, partnerships, or AI/ML-driven product differentiation.

Broad incumbents

• Sodexo Germany: German arm of global facility-services group Sodexo, providing integrated facility management including security and cleaning; a broader incumbent that competes with HEYM for large outsourced facility-services contracts.
• Securitas Holding GmbH: German subsidiary of the global Securitas group, providing manned guarding and security services across Germany; a scaled incumbent competing for the same enterprise and public-sector customers as HEYM, with broader international backing.

Direct peers

• Piepenbrock Unternehmensgruppe: German family-run facility-services group offering cleaning, security, and building services nationwide; directly comparable to HEYM as a multi-division, family-owned German provider with similar customer segments.
• Kötter Services: One of Germany's largest family-run security and facility-services groups, offering manned guarding, alarm monitoring, and cleaning across multiple branches — directly comparable to HEYM in service portfolio, German geographic focus, and family-owned structure.
• Stölting Service Group: German security and cleaning services provider operating across multiple regions; directly comparable service mix (guarding, alarm, cleaning) and customer segments to HEYM, with a similar mid-sized German footprint.
• Dussmann Group: German facility-services group with a security division (Dussmann Sicherheit) plus cleaning and technical services; competes with HEYM for enterprise, public-sector, and industrial clients in Germany.
• Gegenbauer Sicherheitsdienste: Berlin-based German security and facility-services company offering manned guarding, alarm response, and cleaning; comparable in scope and German regional orientation, and a competitor in the same enterprise and public-sector RFP pool.
• Wisag: Major German facility-services provider combining security, cleaning, and technical building services; overlaps directly with HEYM's three-division offering and competes for the same enterprise and mid-market contracts in Germany.

Regional players

• Sicherheit Nord GmbH & Co. KG: Northern German security services provider focused on manned guarding, alarm monitoring, and intervention — overlapping with HEYM's Lüneburg region and northern Germany service territory.

Others

• Dekra Security Solutions: German testing, inspection, and certification company with a security solutions division; adjacent to HEYM via security services and certified alarm-monitoring offerings, though broader in scope and not a pure facility-services competitor.
