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.

Abdulhamid Haidar is the founder and CEO of Darsel, a nonprofit that teaches K-12 math over text messages. Instead of apps and video that assume reliable Wi-Fi, Darsel runs entirely on WhatsApp, Facebook Messenger and SMS, using AI-powered adaptive algorithms to tutor students in Jordan, India and Nigeria. Built during the 2020 COVID lockdown by a Syrian-American who grew up in a family of teachers, Darsel has had more than 120,000 students answer over 170 million math questions. Haidar holds degrees from MIT, Harvard Kennedy School and Stanford's Graduate School of Business, and previously spent three years at McKinsey. His goal: meaningfully reach 100 million students by 2030.
