Create a big, profitable company; bootstraping, without investors to press you to have an exit. And be rich with your profit (remember the good old 20th century capitalism?).
I was just reading the case of weheartit.com - a brazilian "clone" of Pinterest. The quotation marks are there because Weheartit became big before Pinterest even exist.
They became big, but refused any external investment, while Pinterest were genius of raising funding.
There are two sides here: one is that Weheartit lost a billion dollar oportunity to Pinterest for both trying to bootstrap on 37signals style and/or just having worst execution.
Other is that Weheartit is still very big, with regular traffic, and surely large revenue from ads. They didn't die because of Pinterest, they are still a huge company, only by anchoring them to a billion dollar clone one may not call them a successfull company. And their founders are perhaps cashing out dozens (hundreds?) of thousands of dollars each month.
