Who invested in Google early on?

other angels/early investors:

Ram Shriram (angel)
Ron Conway (through Angel Investors LP)
David Cheriton (angel)

both Ram and David became billionaires (like Andy) from their angel investments so i'm assuming it was of the same magnitude ($100k ish) at around the same valuation (before kleiner and sequoia put in $25M at $100M pre)…

Who invested in Facebook?

Mark Zuckerberg put in some money early on along with Eduardo. Also in the series A round (led by Peter Thiel) Mark Pincus and Reid Hoffman independently invested some money.

Greylock and Meritech invested in between Accel's investment and the DST investment.

Also Microsoft invested $240 million at $15 billion in October 2007.
