This website boasts of 59 million users currently and there is already a rumor that Microsoft is salivating even while thinking about acquiring it. Hey, this is just news that I read somewhere in the web, so don't take it seriously.
Now about the investing company:
The man behind the scene of FaceBook is Mr. Peter Thiel and he is reported to be the owner of
Founders Fund, a venture capital organization.
He first laid down $500K for this project. I think that has increased to 50 times in value on paper.
He was formerly the CEO of PayPal Inc.
