What Nux does

Nux s.r.o. is a privately held Czech web development and managed services firm founded in 2005 and headquartered at Durychova 101/66, Prague 4. The company designs, builds, hosts, and operates custom web applications for enterprise and mid-market clients, operating on its own hardware infrastructure across Czech data centers (DC7, OPND). Its service catalog spans six core product lines — investment portals, developer (real estate) project sites, custom web applications, e-learning platforms, authenticated client sections, and e-commerce sites — augmented by an "Online Office" offering that implements open-source collaboration tools (Mattermost, Jitsi, Nextcloud) with pricing decoupled from active user counts. A 15+ year-old proprietary development platform underpins delivery for medium and smaller projects, and the firm operates a TF-CSIRT-member security team with a paid responsible disclosure program.

Revenue is generated primarily through project-based custom development contracts bundled with managed hosting, infrastructure, and SLA-bound ongoing support; pricing is bespoke and not publicly disclosed, and contracts typically run on multi-year cycles. The go-to-market is direct, sales-led, and domestically focused on the Czech market, supported by named enterprise references including Škoda Auto, Penta, Trigema, Intersport, INVESTIKA, Oaks Prague, and Městská divadla pražská. The company employs approximately 20-50 staff across frontend, backend, and administration functions under a leadership team of two managing directors (CTO Radek Růžička, CFO Josef Řeháček), a CSO, and two department heads, and is currently hiring additional PHP and full-stack engineers. Nux holds a registered Czech trademark (No. 291932) and operates without disclosed external funding, parent company, or subsidiaries.
