What Master Internet does

Master Internet, doing business as MasterDC, is a Czech Republic-based hosting and managed infrastructure provider headquartered in Brno with nearly 30 years of operating history (founded 1996). The company operates two owned data centers in Prague and Brno and is constructing a third, AI-focused facility in Kanice u Brna scheduled for Fall 2026. Its core offerings span VPS, dedicated servers, VMware-based cloud hosting, colocation, managed services, security operations (including an in-house CSIRT), backup and storage, custom software development, and AI infrastructure (GPU-accelerated servers and AI model deployment environments). Pricing is modular and consumption-based at the unit level (VPS from approximately $11/month, dedicated servers from $135/month, managed services from $60+/month), with larger contracts negotiated for enterprise customers.

MasterDC serves a diversified customer base across large enterprises and mid-market firms in the Czech Republic and broader Central Europe, with named customers spanning banking (Komerční banka), telecom (T-Mobile), media (Prima), electronics (Sony), insurance (Direct pojišťovna), healthcare (EUC), e-commerce (Rohlik, Siko), logistics (Cargotic), fintech (Roger), cybersecurity (Flowmon), and consumer/weather apps (Annie Baby Monitor, In-počasí/Ventusky). Several relationships are long-tenured (9-17 years), indicating strong retention on managed workloads. The company holds eGovernment Cloud Level 3 certification alongside ISO 9001 and ISO/IEC 27001/27017/27018, positioning it for regulated public-sector and enterprise workloads.

The business model combines recurring infrastructure subscriptions (hosting, cloud, colocation) with higher-margin managed services and custom development. MasterDC is privately held (s.r.o.), has not raised disclosed external venture or private equity funding, and reinvests operating cash flow into capacity expansion and certifications. Strategic ecosystem partnerships with Dell (first CSP partner in Czech Republic), AWS (Direct Connect), VMware, Microsoft, Fortinet, Arelion, and participation in the FENIX security project and RIPE NCC reflect a deliberate multi-cloud, security-anchored go-to-market approach.

• WEDOS: WEDOS is one of the largest Czech hosting providers offering shared hosting, VPS, dedicated servers, and domains. Overlaps with MasterDC on VPS/dedicated server offerings and Czech SMB customer base, though more weighted toward smaller customers.
• Active24: Active24 (now part of IGNUM/NIC.cz group) is a long-standing Czech hosting and domain provider delivering VPS, web hosting, and managed services. Competes with MasterDC across core hosting SKUs to Czech SMB and mid-market customers.

Broad incumbents

• OVHcloud: OVHcloud is a major European cloud and bare-metal infrastructure provider with global data centers. Competes with MasterDC on dedicated servers, public cloud, and VPS but at much greater scale and across geographies; relevant as the broader European incumbent MasterDC positions against.
• Hetzner: Hetzner is a large German hosting provider known for dedicated servers, VPS, and cloud services across European markets. Overlaps with MasterDC on dedicated server and VPS offerings; broader geographic reach but less local Czech sovereign-cloud positioning.
• Leaseweb: Leaseweb is a global hosting and infrastructure provider offering dedicated servers, cloud, and colocation across 20+ data centers. Competes with MasterDC in the dedicated server and colocation space, particularly for enterprise customers with multi-region requirements.

Others

• Dell Technologies: Dell Technologies is MasterDC's primary hardware partner (Dell PowerEdge servers, EMC storage). As the first Dell CSP partner in Czech Republic, the relationship is strategic; included as an ecosystem enabler rather than direct competitor, but Dell's own APEX and infrastructure offerings create indirect competitive overlap.
