In 2001, when the money was flowing, everyone's solution for any startup's problem was to throw money at it. Today, there many other outlets for growing an intelligent idea: blogs, press, alternative incentives programs. And minimal hardware/software costs to build such a product. While PayPal, in 2001, could maybe not have been built lean. It is very possible for the next PayPal-like startup to disrupt the market now on a micro-budget.
