Sal Khan is the founder and CEO of Khan Academy, a nonprofit with a mission of providing a free, world-class education for anyone, anywhere. It started as a passion project in 2004, when he began tutoring his cousin in math, communicating by phone and using an interactive notepad. Word got around, and soon Khan was tutoring several cousins and family friends as a hobby. To better scale, he began writing software to assign math practice, provide feedback and track each student’s progress. He also began posting videos of his hand-scribbled tutorials on YouTube, where he reached thousands of students. In 2009, he quit his day job and launched Khan Academy as a nonprofit organization.
Today more than 62 million registered users access Khan Academy in dozens of languages across 190 countries. Khan Academy offers free lessons and practice in math, history, grammar, physics, biology and many more subjects, as well as free SAT® prep in partnership with the administrator of the test, the College Board.
Khan has been recognized as one of TIME’s 100 Most Influential People in the World. In his book, “The One World Schoolhouse,” he outlines his vision for the future of education. These ideas are the basis for Khan Lab School, a nonprofit laboratory school he founded in Mountain View, California, where he teaches seminars in the humanities and sciences.
