What Kattis does
Kattis is a Stockholm-headquartered, privately-held code evaluation and technical assessment platform operating across three integrated go-to-market motions: enterprise technical recruitment, university computer science education, and a competitive programming developer community. Its core technology is a cloud-based automated grading engine that compiles, executes, and scores code submissions across more than 70 programming languages, augmented by a built-in plagiarism cross-checker that flags suspicious similarity in seconds, and a proprietary variant of the Elo rating system that estimates problem difficulty and user proficiency from solve rates and submission patterns. The company serves enterprise hiring teams via dedicated subdomains and a demo-led sales motion (customers include Klarna, Capgemini, Paradox Interactive, Academic Work, and Dynabyte), universities via per-seat tiered licensing (Standard at €25 and Premium at €39 per student per course, with OAuth 2 SSO and fixed-price options), and individual programmers through the open.kattis.com community platform integrated with the ICPC and IOI competitions. Kattis operates with a small team (1–10 employees) from Stockholm and a US office in Waco, Texas, with no disclosed external funding, suggesting a capital-efficient, organic-growth business model anchored by subscription per-seat revenue from education and quote-based recurring contracts from enterprise hiring.
