Five ways to build a $100 million business

To build a Web company with $100 million in annual revenues*, you essentially need:

1,000 enterprise customers paying you $100k+ per year each; or
10,000 medium-sized companies paying you $10k+ per year each; or
100,000 small businesses paying you $1k+ per year each; or
1 million consumers or "prosumers" paying you $100+ per year each (or, in the case of eCommerce businesses, 1M customers generating $100+ in contribution margin** per year each); or
10 million active consumers who you monetize at $10+ per year each by selling ads
