The State of Marketing APIs

About this report
Marketing is not one market and it does not behave like one. The distance between its most programmable corner and its least is twenty-six points of Kin Score — owned channels at 60.2, sell-side paid media at 34.0 — against a 4.7-point gap between the marketing and revenue medians overall. Almost everything worth knowing here is inside marketing rather than between marketing and something else, which is why a single median for the category is close to useless and why this report is published alongside eleven area reports.
814 companies. Kin Score median 49.1, Agent Readiness median 42.7. 155 reach the Exemplar band; 203 sit in Emerging or Minimal. Every one of them is named and ranked in the report — if you work in this market, you are in the table, and so is everyone you compete with.
The strongest divide in marketing software is not category, it is customer. Software sold to the advertiser scores 53.3; software sold to the publisher scores 39.0. Both sides run the same real-time auctions against each other. One of them documents how.
