School24

What School24 does

School24 is a Netherlands-based online learning platform for Dutch secondary education, operating under the holding entity OnlineSlagen B.V. (legal name: OnlineSlagen B.V., jurisdiction: Netherlands, founded 2021, headquartered in Amsterdam). It targets students across all Dutch secondary school tracks (VWO, HAVO, VMBO GL/TL, VMBO KB, VMBO BB) from the first year (brugklas) through the examination year, as well as the teachers and schools that serve them. Its product surface comprises animated explanatory videos (Uitlegvideo's), step-by-step practice exercises (Oefenopgaven), topic summaries (Samenvattingen), vocabulary and terminology flashcards (Begrippen & Woordjes), and an unlimited practice-testing environment (Toetsomgeving), supplemented for schools by a Teacher Dashboard (Docentendashboard) with real-time performance monitoring, assignment tools, and feedback capabilities. The underlying technology is a standard web platform hosted on DigitalOcean EU B.V. with server management via Versio B.V. and customer chat provided by Freshworks; no proprietary AI/ML engine, no patents, and no public API or SDK are documented in the available data.

The business model operates two parallel monetization streams. On the consumer side, students self-serve through portal.school24.nl on a freemium basis: a free "Basis" tier exposes summaries, while a "Premium" subscription is priced at €9.50 per month with a 7-day free trial and unlocks all subjects, levels, and features. On the institutional side, School24 sells multi-year per-student licenses to Dutch secondary schools at €15/student/year for a single subject or €35/student/year for all subjects, inclusive of the Teacher Dashboard and unlimited support. Go-to-market is correspondingly dual: product-led growth (self-serve sign-up, TikTok- and Instagram-led organic social acquisition, content marketing through study-tip blogs) for individual students, and a sales-led motion with online demonstrations and quotes for school accounts. As of the available data, the platform claims 70,000+ student users, 86% reporting faster learning, and 92% reporting higher grades, although these figures are self-reported. Revenue, funding, headcount growth, and ownership beyond the OnlineSlagen B.V. parent entity are not publicly disclosed.
