What Trelson does
Trelson AB is a Swedish education-technology company founded around 2014 and headquartered in Stockholm, building a digital assessment and classroom management platform for K-12 schools. The product combines a lockdown browser (available as a Chromebook kiosk app, a Chrome extension, and integration with Safe Exam Browser on Windows/Mac) with real-time student screen monitoring, automatic grading, exam-template reuse, anonymous submission handling, and an extensive assistive-technology suite (reading guides, text-to-speech, speech-to-text, math/equation editor) certified for WCAG 2.1 AA. The platform was originally designed for Google Workspace for Education and deepened that integration through add-ons such as Trelson Class Manager (Google Classroom roster synchronization) and Trelson Mail Switch (Chrome extension redirecting Gmail to Outlook); Microsoft 365 Education support — including SharePoint, OneDrive, Teams, and Entra-based deployment — was added in November 2025, materially expanding the addressable ecosystem to roughly the full population of Google- and Microsoft-based schools. The product is offered in 14 languages and is available in 4 on the website (English, Swedish, Spanish, Norwegian bokmål).
The business model is a per-student, annual SaaS subscription (Class Manager publishes at 10 SEK per student per year; main-platform pricing is quote-based and not publicly disclosed), supplemented by paid professional training delivered by practicing-teacher product specialists and a free tier of Class Manager used as a freemium funnel. Distribution is sales-led — a direct sales team ([email protected]), demo booking, free advisory consultations, and self-service free trials — augmented by education-sector event participation (notably the SETT Nordic EdTech fair), webinars, content marketing, and distribution via the Chrome Web Store and Microsoft marketplace channels. The company states it has served 'hundreds of thousands' of educators and students primarily in Sweden and the UK, with named customers including Swedish municipalities, international schools in Malaysia, and individual schools in the UK and Sweden.
Since 2024, Trelson has executed a series of strategic moves: a rebrand from 'Trelson Assessment' to 'Trelson' (November 2024) to reposition the product beyond exam-only use; the launch of Focus Room (2025) extending lockdown functionality to daily classroom instruction; CEO transition from founder Jonatan Brown to Mimmi Berg; partnerships with educational publisher Gleerups (2024-04) and writing tool SkrivaText (2025-03); and Microsoft 365 Education support (2025-11). The company is privately held with no publicly disclosed funding rounds, suggesting organic, self-funded growth.

Trelson competitors and assessment
Company assessmentDirect peers
- Proctorio: AI-driven remote proctoring and lockdown solution integrated with LMS platforms. Overlaps with Trelson's real-time monitoring and lockdown functionality for digital exams, with a heavier focus on proctoring analytics.
- Haldor: Swedish-Nordic assessment and digital exam platform for K-12 schools, with a similar focus on secure digital exams and integration with school ecosystems. Direct regional competitor to Trelson in its home Nordic market.
- Respondus: Respondus LockDown Browser and Monitor are leading commercial lockdown and proctoring tools integrated with major LMS platforms. Targets the same K-12 and higher-ed digital assessment use cases as Trelson, with broader LMS coverage.
- Safe Exam Browser: Open-source device lockdown browser widely used in K-12 and higher education for secure exams. Trelson explicitly supports SEB integration for Windows/Mac lockdowns, making it a direct functional peer in the secure exam browser category.
- ExamSoft: Enterprise assessment platform for high-stakes exams with offline and lockdown capabilities. Competes with Trelson in the secure digital assessment category, particularly for national/professional exams and large institutions.
Broad incumbents
- Turnitin: Broad academic integrity and assessment platform used across K-12 and higher education. Owns Gradescope and competes with Trelson in academic integrity workflows, but offers a much wider portfolio (plagiarism detection, feedback, grading).
- Microsoft Teams for Education: Microsoft's education collaboration and assignment platform, integrated with Trelson via Entra/SharePoint. Functions as both a distribution channel and a long-term competitive threat if Microsoft expands native assessment lockdown features.
- Google Classroom: Free core LMS/assignment tool from Google for Education, into which Trelson integrates. Represents both a key distribution channel and a potential competitive substitute for assessment workflows at the low end of the market.
Emerging players
- Satchel One (Show My Homework): UK-focused homework, behavior, and classroom management platform widely used in British secondary schools. Overlaps with Trelson's UK presence and Focus Room classroom management use case.
- ManageBac: Platform for international schools covering curriculum, assessment, and reporting (used by IB schools). Competes with Trelson for international-school segment customers such as Spectrum International School Malaysia, with broader curriculum management functionality.
