The State of Paid Media APIs — The Buy Side

About this report

The third-largest area in marketing and the second-least programmable. This is where the money is: demand-side platforms, bid management, campaign tooling — software whose entire purpose is spending a budget across inventory faster than a person could. An industry built on machine-to-machine bidding at millisecond latency publishes a machine-readable contract 40% of the time.

252 companies. Kin Score median 35.7, Agent Readiness median 30.1. 25 reach the Exemplar band; 92 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.

This market transacts entirely by machine and describes itself to the outside world less than almost any other. The bid stream is a specification. The platform is not.
