What Cesky Internet does

ČESKÝ INTERNET s.r.o. (operating publicly as Cesky Internet) is a privately held Czech digital media company founded in 1999 and headquartered in České Budějovice. It operates a network of more than 300 internet portals organized into four vertical clusters: real estate (ČESKÉREALITY.cz and the RealitníServery.cz network of 300 domains), construction and housing (ČESKÉSTAVBY.cz), accommodation (HotelyPenziony.cz and the ČESKÉUBYTOVÁNÍ.cz network of 78 servers), and travel (e-Dovolená.cz, acquired in 2010), with a newer culinary property (ČESKÝKULINÁŘ.cz). The portfolio collectively serves more than 1 million monthly visitors and roughly 25 million annual visits, and is built on a conventional LAMP-style web stack (PHP, MySQL, jQuery).

The company monetizes this audience primarily through B2B online advertising (display banners and branding), subscription and listing fees paid by Czech real estate agencies and accommodation providers, and remarketing services. It serves more than 4,000 clients, including 1,000+ real estate agencies that use its listing/CRM export tools, alongside enterprise advertisers such as CENTURY 21, RE/MAX, HELUZ, FAKRO, LAUFEN, and KÄRCHER. Go-to-market combines a České Budějovice headquarters with regional sales offices established in 2012, plus mobile applications launched in 2020 and a hybrid application introduced in 2026. The business is founder-owned (Ivo and Jan Stejskal), employs approximately 50 staff plus collaborators, and operates without external funding, reinvesting cash flow into product development and selective acquisitions such as the 2019 purchase of marketing agency Lewest s.r.o.

Broad incumbents

• Booking.com: Booking.com is the global leader in accommodation bookings. While primarily transactional rather than directory-focused like HotelyPenziony.cz and ČESKÉUBYTOVÁNÍ.cz, it competes for the same Czech accommodation provider marketing budgets and end-user accommodation search demand.
• MAFRA (Mladá fronta DNES / iDNES.cz): MAFRA is a leading Czech media group owning iDNES.cz news portal (including Reality.iDNES.cz) and other media properties. As a broad incumbent, it competes for Czech advertising budgets and offers integrated advertising solutions across news, real estate, and classified verticals.
• Seznam.cz: Seznam.cz is the dominant Czech search engine and portal operator, owning Sreality.cz and Firmy.cz. As a broad incumbent, it competes indirectly by controlling organic search traffic distribution and operating competing vertical marketplaces across real estate, accommodation, and business directories.

Others

• Trivago: Trivago is a hotel metasearch engine that competes indirectly for Czech accommodation search demand. While it does not offer listing services to accommodation providers like HotelyPenziony.cz, it diverts end-user traffic away from Czech accommodation portals through price comparison features.

Direct peers

• Sreality.cz: Sreality.cz is the leading Czech real estate portal owned by Seznam.cz, the dominant Czech search engine. It directly competes with ČESKÉREALITY.cz and RealitníServery.cz in property listings, B2B advertising, and SEO-driven traffic acquisition for Czech property seekers.
• Bezrealitky.cz: Bezrealitky.cz is a direct Czech real estate portal focusing on direct listings (no agents), serving a similar buyer/seller audience as ČESKÉREALITY.cz. It competes in the same property listing marketplace with a differentiated agent-free positioning.
• Reality.iDNES.cz: Reality.iDNES.cz is the real estate vertical of iDNES.cz, the largest Czech news portal owned by MAFRA. It directly competes for Czech property listings and real estate advertising spend, leveraging cross-traffic from iDNES news content.
• RealityMIX.cz: RealityMIX.cz is a Czech regional real estate aggregator and portal competing in the same vertical as RealitníServery.cz, aggregating listings from multiple regional sources across the Czech Republic.
• Eurobydlení.cz: Eurobydlení.cz is a Czech real estate portal offering residential and commercial property listings, comparable to ČESKÉREALITY.cz in serving Czech buyers, sellers, and real estate agencies with subscription-based listing services.

Emerging players

• Firmy.cz: Firmy.cz is a major Czech business directory owned by Seznam.cz, serving a similar SME listing and advertising function as the company's business directory on ČESKÉSTAVBY.cz. It competes for Czech business listings and B2B advertising in overlapping verticals like construction and home services.
