What it does: Provides network-neutral data centers for businesses.
IPO Date: August 11, 2000
Money raised: $240 million
What exactly is a network-neutral data center? It's a place where an Internet company can run its server computers. In today's world, that's a big business. Equinix capitalized early with a $95 million venture round in June of 2000, then went ahead and filed for an IPO underwritten by Goldman Sachs. And where'd all that money go? To the development and construction of new data centers, of course. Oh, and to a charity: Equinix Foundation charitable fund.
