I would argue Google because the dot-com bubble did not burst till 2000, and Google was founded in 1998.

Also, Netflix was founded Sep 1997. Also, Paypal, founded Oct 1999. Also, Ebay, founded 1995, [del: though Ebay and Paypal together today are worth only 23.8 billion dollars. :del]

I think a lot of the money made by founders and angel investors during the dot-com era was made by selling a startup to an established company for 100s of millions of dollars, which is pretty good money since it often took only took 5 years to go from the founding event to such an exit, but I cannot think of an easy way to get a list of such exits.

ADDED. In writing the above, I assumed Paypal was still part of Ebay. In reality they are separate companies again with market caps of 23.8 and 84.59 billion dollars.

... Huh, never knew Netflix was that old. That's less than a year after DVDs were released!

Interestingly, Netflix has its origins in a... more typical dot-com-era story: https://en.wikipedia.org/wiki/Pure_Software
