Darsel
Darsel is an education-technology nonprofit that teaches K-12 math over the messaging apps students already have. Instead of an app or a laptop, students practice curriculum-aligned questions through SMS, WhatsApp, and Facebook Messenger, and an AI-powered chatbot delivers hints, explanations, and personalized practice while auto-grading homework and reporting progress to teachers. Founded by Stanford MBA and MIT alum Abdulhamid Haidar during the COVID-19 lockdowns, Darsel has grown from a spring-break prototype to a platform used across Jordan, India, and Nigeria, reaching hundreds of thousands of students who have answered hundreds of millions of math questions.
