Tele3 S.r.o.

What Tele3 S.r.o. does

Tele3 S.r.o. is a privately held Czech internet-infrastructure provider founded in 2005 (originally as HOSTING4U s.r.o., renamed in 2008) and headquartered in Prague. The company operates as an accredited .CZ domain registrar — a status it has held since 2008 in partnership with CZ.NIC — and has ranked among the Top-10 Czech registrars continuously since 2010. Its core offering is a vertically integrated catalog covering the full internet-service lifecycle: domain registration and transfer (with API and bulk operations up to 100 domains per batch), DNS hosting across four geographically distributed authoritative servers (two in the Czech Republic, one in Germany, one in the USA) with DNSSEC enabled by default, paid and free web hosting with PHP 5.6–8.x and Let's Encrypt SSL, multiple VPS configurations (web server, MailCow-based mail server, DNS server, media server), physical server hosting and rental in climate-controlled Telehouse facilities, server management and monitoring, commercial SSL certificates, and SMS gateway services via GSM terminal rental. The technology stack is conventional open-source infrastructure — Proxmox Virtual Environment, Nginx, Apache, MailCow, DNSSEC, Ubuntu/Debian servers — supplemented by proprietary tooling such as an internal domain-backorder system for expired .CZ domains (operational since ~2010) and a prepaid credit system with automatic payment matching within five minutes via Fio banka and Raiffeisenbank integrations.

Tele3 operates with 1–10 employees and runs its infrastructure across multiple partner data centers including Casablanca INT (primary since 2005), Coolhousing (since 2006), Master DC (Prague and Brno), and others. Its customer base mixes a long tail of self-served domainers, SEO professionals, web developers, SMEs, and individual website owners with a smaller set of named enterprise customers (e.g., DHL Express, Linde Gas, Nakladatelství C.H. Beck, Auto ESA, Malaysia Embassy) and non-profit organizations served under a sponsorship program offering up to 100% discounts. Pricing follows a subscription/recurring model with usage-based add-ons: paid hosting starts at CZK 10/month, VPS from CZK 490/month, colocation from CZK 1,490/month, and server management from CZK 1,200/hour. The go-to-market is API-first for power users and self-service for the long tail, with direct phone/email sales for enterprise and a referral channel through design studios and ISPs. Geographic focus is overwhelmingly domestic Czech Republic, with technical reach into Germany and the United States via DNS infrastructure. No external funding rounds, no parent company, and no subsidiaries have been disclosed.
