About

Karl Hechema is a 16-year-old founder and entrepreneur based in Dubai. He built PrépaDNB, a suite of AI-powered revision tools for the French Brevet (France's national end-of-middle-school exam), now used by more than 25,000 students across nearly 60 countries. He launched PrépaDNB on the web in October 2025 and brought it to iOS and Android by January 2026 — growing it from a single idea to tens of thousands of users in under a year. His work has drawn regional media attention: Gulf News profiled how he built the platform from his bedroom in Dubai, with further coverage in The CEO Register and The Dubai Standard.
