This post is not at all meant to be about what to do with your bootstrapped business. It's only targeting high-growth, mostly b2c, companies in winner takes all markets with strong network effects (ex: Pinterest, Instagram). That's what I mean when I say "startup" though that term is completely overloaded and adopted by everyone nowadays :)
By his definition, Google was never a startup because they're not in an area with strong network effects. Nor is their money-source B2C---they're sell advertising space to businesses.
