What is already selling
Every company in this space, cheapest to enter against first.
B2B is the majority of the index for the same reason it is the majority of good micro SaaS advice: a business buyer expenses the subscription, tolerates a higher price and churns on budget cycles rather than on mood. The trade is a longer sale, and it is visible here in how long each advertiser keeps a message running.
How this list is drawn: Audience classified as businesses. Ordered by thirty-day ad spend, lowest first - what it costs to be visible against them, not who is biggest.

Revenue is modelled from measured ad spend, not reported by the company. The band beside each figure is the range the model produced and it is wide on purpose - the method page shows the arithmetic and says where it stops being reliable.

Where the buyers are
The markets this space is actually being sold into.
Reach-weighted across every advertiser in the cut, so one small company with a lopsided country mix cannot move the picture.
Which way it is moving
Budgets up, budgets down.
An advertiser raising a budget is the least ambiguous signal available from outside a company. It costs real money and nobody does it against a product that is not converting.
10 of 25 increased spend over the last thirty days; 10 cut it.
