What Zalozba Rokus Klett, D.o.o. does

Založba Rokus Klett, d.o.o. is Slovenia's largest textbook and supplementary educational materials publisher, founded in 1991 and headquartered in Ljubljana. The company produces validated printed textbooks and a portfolio of digital educational platforms organized around its flagship Radovednih pet series for primary school students, the Lilibi portal for first-triennium students (grades 1-3), and iRokus/iRokus+ interactive digital textbooks covering biology, chemistry, physics, and natural sciences. Additional offerings include IzziRokus and Znam za več supplementary materials, the Modra akademija online teacher training platform, the Jezikovni center Klett language center, the Knjigarna.com e-commerce bookstore, and licensed publications such as National Geographic Slovenia. A unified SSO user account system (uporabnik.rokus-klett.si) connects the digital ecosystem across subject areas.

The company operates a multi-channel distribution model: dedicated regional school representatives sell directly to educational institutions, a nationwide bookstore partner network handles retail distribution (with trade discounts of 10-27%), and digital platforms are deployed via school-wide access codes. Revenue is generated through one-time textbook sales, annual digital subscriptions tied to the school year, professional development programs such as the Rokus Academy and 'Učitelj v svetu sprememb' (Teacher in a World of Change), and language center services. Pricing is B2B-oriented with teachers able to purchase additional subject access for €10 per school year.

Customer base extends to 375 primary schools (using Rokus for Slovenian language instruction), 67,854 students (mathematics), 59,900 students (history), and 4,357 teachers in the first triennium. The company is privately held by Maruša Dejak (Managing Director) with no external funding rounds, operates exclusively in Slovenia, and maintains a strategic co-publishing partnership with Modrijan Izobraževanje, d.o.o. at the same Ljubljana address.

Broad incumbents

• Scholastic: Large US-headquartered children's book and educational publisher with K-12 classroom magazines, book clubs, and digital learning. Comparable in K-12 content portfolio and teacher-channel distribution, though at vastly greater scale.
• Pearson: Global education publisher with K-12 and higher-education textbooks plus digital learning platforms. Comparable on the integrated print + digital curriculum model, though operating across many markets rather than focusing on a single small-language market.
• Oxford University Press: Global educational publisher with primary and secondary course materials and English-language-teaching resources. Comparable in the ELT and validated-textbook segments of Rokus Klett's portfolio, particularly the Klett language-learning editions.
• McGraw Hill: Major US K-12 and higher-education publisher with validated textbook series and adaptive digital learning tools. Comparable on curriculum-validated textbook + digital platform model, though at significantly larger scale.
• Houghton Mifflin Harcourt: US K-12 publisher offering validated core curriculum textbooks and digital platforms across ELA, math, and science. Comparable subject coverage and blended print/digital delivery model.
