The Bay Area companies may not be public yet but you can still get your hands on a piece of the billion dollar valuations. That is if you already have a fairly sizable valuation of your own.
In another example of the rich get to have all the fun, some of the Bay Area's hottest private companies have shares available for investors but they have to be people who are already wealthy.
The companies link people with hefty portfolios with company insiders who want to sell some of their shares. There is no specific price to get into the game per se, but each transaction has a minimum $1,500 bank fee to close a deal.
