Celos Computer

What Celos Computer does

Celos Computer is a privately held German IT managed services provider headquartered in Ulm, with regional offices in Ingolstadt (operated through the wholly owned subsidiary Celos Computer Ingolstadt GmbH) and Augsburg. Founded in 1990/1991 and now in its 35th year of operation, the company serves small, mid-sized, and enterprise customers across southern Germany (Baden-Württemberg and Bavaria), primarily within roughly 100 km of its three offices. Its core offering is a nine-pillar service portfolio spanning cybersecurity (EDR/XDR/MDR, SIEM, penetration testing, immutable backups, zero trust), managed services (service desk, monitoring, patching, 24-hour on-call), a company-operated DSGVO-compliant managed data center in Ingolstadt, IT support, IT project management, hardware and software procurement, unified communications (3CX, Microsoft Teams telephony), and DATEV-certified services for tax advisors, auditors, and lawyers.

The underlying technology stack is built on best-of-breed vendor partnerships rather than proprietary IP: ESET for endpoint and MDR (Platinum tier), Fortinet for network security, Microsoft for cloud and productivity, Veeam and Veritas for backup, IGEL for endpoints, VMware and Citrix for virtualization, and DATEV for accounting workflows. The company runs its own data center in Ingolstadt, billing on RAM and storage consumption rather than CPU or bandwidth, and uses the Ingram Micro CloudBlue Commerce platform as a Cloud Solution Provider for Microsoft and cloud licensing. Supporting assets include the Celos Academy (academy.celos.de), a remote-maintenance capability via Supremo and TeamViewer, and a 'Simply the Best' apprenticeship program.

The business model is a mix of recurring managed services contracts (typically monthly subscriptions for service desk, monitoring, MDR, managed firewall, and backup), project-based professional services quoted on time-and-materials or fixed-price terms, hardware and software resale (Dell, HP, Lenovo, Fujitsu, Microsoft, etc.), and Microsoft CSP licensing margins. Go-to-market is primarily direct enterprise field sales at each of the three offices, supplemented by the CSP channel portal. The company is founder/management-owned (managing directors Thomas Hoffmann, Valon Dermaku, Oliver Sperl, and Armin Krieglmeier), with no institutional or external shareholders identified.
