What Web4U does

Web4U s.r.o. is a privately held Czech web hosting and internet infrastructure provider founded in 2000 and headquartered in Prague. The company operates shared web hosting across six pricing tiers (VIZITKA through KOMPLET, from free to CZK 260/month excluding VAT), domain registration across 350+ TLDs (67,996 domains managed, with 42,688 .CZ, 9,444 .EU, and 7,817 .COM), and server hosting spanning Linux virtual servers (from CZK 388/month), Windows virtual servers on Hyper-V (CZK 450-1,370/month), dedicated servers, managed servers, and server housing. Supplementary products include VPN (63 locations, AES-256, from CZK 102/month), BaseKit website builder, one-click CMS installations (WordPress, Joomla, Drupal, PrestaShop), and DNSSEC for .CZ domains. Infrastructure is built on Supermicro servers with SSD storage, Juniper networking, proprietary wCluster storage, and own autonomous system AS39790, hosted across two geographically separated Prague data centers (DC Tower as primary critical-infrastructure facility with 99.999% uptime, T-Mobile THP as backup).

The go-to-market model is predominantly self-serve online (PLG) with a direct-to-consumer website supporting Czech, English, and Slovak, complemented by an affiliate referral program (10% recurring commission plus CZK 100-500 signup bonuses) and a SOAP-based Domain API serving resellers and bulk domain operators. Customer concentration is low and spread across SMBs, individual developers, privacy-conscious VPN users, and named enterprise accounts spanning gaming (Kindred Group), logistics (Zásilkovna), nonprofit (Czech Red Cross), publishing (Kosmas), and education (Metropolitní univerzita Praha). Revenue streams are recurring subscription (hosting, domains, servers, VPN) plus hourly professional services for server administration (CZK 1,500-2,000/hour) and affiliate referral payouts. The company is an accredited .CZ registrar (CZ.NIC member) and FENIX project participant, holding a registered trademark (OZ/180331). No external investment, acquisitions, or restructuring events are documented; ownership remains private and undisclosed.
