$12, one audit at a time

This table is what a business shows in public. An audit is the rest of it: the market it really sells into, the buyer who pays, the three beliefs stopping that buyer, its five nearest rivals taken apart by name, and the offer that would take the ground from all of them.

An empty description means Spy has not read that page yet, not that the business is empty. Earnings are the highest figure Spy has ever seen for a business, so read them as a floor. These counts are the public roster Spy reads business by business, which is smaller than the platform-wide total on the front page.
