What is already selling
Every company in this space, cheapest to enter against first.
A market with a $2M-a-month incumbent is a market with a marketing budget you cannot answer. Below $100,000 the incumbent is a small team with a real product and no moat made of money, which is the only kind of proven market a new entrant can actually walk into.
How this list is drawn: Modelled monthly revenue below $100,000. 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 29 increased spend over the last thirty days; 8 cut it.
