 Jimmy Wales

Jimmy Wales is an American internet entrepreneur best known as the co-founder of Wikipedia, the free online encyclopedia that allows users to create and edit articles collaboratively. Wales was born on August 7, 1966, in Huntsville, Alabama. He co-founded Wikipedia in 2001 along with Larry Sanger, and it has since grown to become one of the largest and most popular reference websites on the internet.

One thing to note is that Jimmy was a finance worker before starting wikipdia, e.g. he had capital to hire Larry Sanger.

Maybe that's the way to go about it, make money first, and later on change the world.

Starting just after the beginning of the Internet can't hurt either. Though tooling must have been insane back then.
