Overview

Sal Khan shares the remarkable story of how tutoring his cousin in math led to the creation of Khan Academy, now a free online learning platform used by millions worldwide. Starting from simple phone calls and Yahoo Instant Messenger sessions in 2004, Khan eventually quit his lucrative hedge fund job to pursue his vision full-time as a nonprofit. Despite months of financial stress and uncertainty, unexpected support from philanthropists like Ann Doerr and Bill Gates helped transform Khan Academy into a global educational resource. Khan discusses the challenges of scaling while maintaining quality, his decision to remain nonprofit despite lucrative for-profit opportunities, and his belief in making world-class education freely accessible to anyone, anywhere.

Early Life and Education in Louisiana

Sal Khan grew up in Metairie, Louisiana, raised by his single mother who worked minimum wage jobs after his parents separated when he was young. Despite financial struggles and being the only brown kid in his classroom, Khan thrived academically, inspired by his mother's courage and the opportunities provided by the Jefferson Parish school system. His childhood was colorful, living with young uncles who embraced New Orleans culture, and he even sang in a death metal band called Malignancy before choosing academics over music.

  • Sal's parents separated when he was 18 months old; he only saw his father once at age 13 before he passed away
  • His mother raised him as a single mother, working jobs like collecting change from vending machines and as a convenience store cashier
  • Sal was the only brown kid in his classroom but received strong support from teachers and had good friends
  • He was lead singer of a death metal band called Malignancy but chose to pursue academics instead of their first big gig
  • A pivotal moment came when his mother broke down at Kmart, revealing their financial struggles when he was 8 or 9 years old
" My mother is a very courageous person. I still remember I must have been eight or nine years old at Kmart, and I was being a brat. I really wanted to buy this Hot Wheels set, and I was throwing a tantrum in the Kmart, and I remember that was the first time that my mom kind of just broke down a little bit and says, don't you realize we have no money? "
" Louisiana was as close to South Asia as the United States could get. It had spicy food, humidity, giant cockroaches, and a corrupt government. "

From MIT to Wall Street Success

Khan attended MIT where he thrived in the intellectually stimulating environment, comparing it to Hogwarts for science enthusiasts. After graduating with a master's degree, he took a job at Oracle for the impressive $100,000 salary—a life-changing amount given his $25,000 debt and his mother's $16,000 annual income. He later joined a startup during the dot-com bubble before attending Harvard Business School, where he discovered a passion for finance and eventually landed a job at a hedge fund despite hundreds of rejections.

  • Khan graduated from MIT with both bachelor's and master's degrees, accelerating his studies after learning friends were making $100,000 at Oracle
  • His first job at Oracle paid $100,000—a transformative salary when his mother made $16,000/year and he had $25,000 in debt
  • He joined a dot-com startup called MeVC that aimed to democratize venture capital but experienced the painful collapse during the 2000 crash
  • At Harvard Business School, he discovered finance had beauty in its quantitative, psychological, and historical aspects
  • Despite hundreds of rejections, he landed a hedge fund job with Dan Wohl, who hired him specifically because he didn't have a traditional finance background
" My mind was blown. My mom was making $16,000 a year. I had about $25,000 in debt, which at the time felt like all the money in the world. So I was getting stressed about it. And I literally remember thinking, like, it would be irresponsible for me not to try to make that type of money, pay off my debt, help out my family, and just get a little bit more financial security. "
" It was the closest thing to Hogwarts in the real world where, you know, science is magic and you can walk down, you know, the main hallway in MIT is called the Infinite Corridor. And you're just seeing, you know, people with like that. Some of them are a little bit unusual in their affect and all of this, but they all have these magical superpowers. "
