Let&#x27;s not forget that most, if not all of these unicorns are not really billion dollar businesses.<p>Just because a16z buys shares at year two at a $100MM valuation, and more shares at year 3 at $400MM valuation, and even more shares at year 4 at $1B valuation does not make you a billion dollar biz.<p>In fact, it says more about a16z bubble inflation methods than anything else.
