Khan Academy's mission:
Our mission is to provide a free, world‑class education for anyone, anywhere.
This is how they describe their story:
What started as one man tutoring his cousin has grown into an 80-person organization. We’re a diverse team that has come together to work on an audacious mission: to provide a free world-class education for anyone, anywhere. We are developers, teachers, designers, strategists, scientists, and content specialists who passionately believe in inspiring the world to learn. A few great people can make a big difference.
Khan Academy is an inspiring organization. I encourage you to learn more about them. You can find them at www.khanacademy.org.
