What Top 21 Systemhaus does
Top 21 Systemhaus GmbH is a Stuttgart-based, full-service IT managed services provider (Systemhaus) founded in 2002 and operating as a privately held GmbH under Managing Director Frank Laich. The company serves approximately 152 small and medium-sized enterprises primarily in Baden-Württemberg, Germany, delivering IT outsourcing, managed hosting, cloud solutions, IT security, consulting, and 24/7 support. Its customer base spans a horizontal mix of verticals — fashion/retail, food service, legal, eyewear, social services, publishing, hospitality, and automotive training — with several clients retained since their own founding, indicating deep operational lock-in.
The technology backbone is an in-house, redundant, virtualized data center in Stuttgart that has been operational for over 10 years, supporting Windows Server, Remote Desktop Services, Linux servers, Windows, macOS/iOS/iPadOS, and Android endpoints. Service lines include managed hosting with automated patch and system monitoring, Securepoint Unified Security Cert+-certified firewall/antivirus/backup management, cloud workstations and cloud backup billed on a usage basis, plus helpdesk and ticket-based support delivered remotely via TeamViewer or on-site. The company is ISO 9001:2015 certified since 2013 and ISO 27001:2022 certified, and it operates an extensive vendor ecosystem including Microsoft, Adobe, AWS, Cisco, Sophos, Veeam, Securepoint, Jamf, Acronis, Dell, HP/HPE, Lenovo, and Apple.
The business model is a direct, consultative sales motion targeting SMEs with no publicly disclosed pricing; revenue is generated through a mix of hardware and software resale with consulting-led procurement, recurring managed services contracts, usage-based cloud billing, and project-based consulting work. GTM is single-country and sales-led, leveraging the company website, LinkedIn, XING, and partner co-selling motions rather than paid digital channels. Headcount of 11-50, founder/management-controlled ownership, and no disclosed funding or M&A activity characterize a mature, capital-light Mittelstand MSP whose growth depends on customer retention, service-line cross-sell (especially cloud and security), and partner ecosystem leverage.
