For Salman Khan (of Khan Academy) to expand his project from his cousin Nadia (2004) to:
- dozens of users (2005)
- hundreds of users (2006)
- thousands of users (2007)
- tens of thousands of users (2008)
- hundreds of thousands of users, quitting his job as a hedge-fund manager, getting $110,000 (from the interested spouse of a venture capitalist), an actual office, and a handful of employees (i.e., other than himself) (2009)
- millions of users and getting multiple millions of dollars (from the Gates Foundation, Google, etc.) (2010)
took: 1. one, 2. two, 3. three, 4. four, 5. five, 6. six years.
