About
Khan Academy is a nonprofit educational platform providing free, world-class K-12 and college-prep education to anyone, anywhere — offering video lessons, interactive practice exercises, and personalized learning tools across mathematics, science, computing, history, economics, and test preparation (SAT, LSAT, GMAT). Founded in 2008 by Sal Khan in Mountain View, California, Khan Academy has grown to 180 million+ registered users globally and generated $107.3 million in revenue in 2023, funded primarily by institutional philanthropy including the Bill and Melinda Gates Foundation and Beneficus Foundation.\n\nKhan Academy's learning model combines short instructional videos with adaptive practice exercises that adjust difficulty based on student performance — the platform identifies knowledge gaps and creates personalized practice paths for each student. Khanmigo, launched in 2023, is an AI tutoring assistant powered by GPT-4 that provides Socratic guidance (asking questions to lead students to answers rather than giving answers directly) for math tutoring and writing feedback. Khan Academy for Schools gives teachers classroom assignment and progress monitoring tools at no cost.\n\nIn 2025, Khan Academy operates as a mission-driven nonprofit competing for educational attention with Duolingo (language learning), IXL (K-12 practice), and edtech platforms like Coursera and Chegg in the broader digital learning space. The Khanmigo AI tutor represents a significant strategic bet — providing personalized tutoring at scale that was previously only available to students who could afford private tutors. Khan Academy's 2025 strategy focuses on expanding Khanmigo adoption, growing its teacher and school partnerships, increasing revenue from donors and Khanmigo subscriptions to fund the mission, and expanding localized content for international learners.
