Top Demand-Side Platform (DSP) Companies [2024]
Demand-side platforms (DSPs) first emerged in the late 2000s when real-time bidding (RTB) started to take flight, with the first DSPs on the market being MediaMath and Rocket Fuel.
Nowadays, there are hundreds of demand-side platforms, offering advertisers and agencies access to all types of inventory — display, native, video, and in-app mobile — across different channels.
Below is a curated list of the main demand-side platforms operating in the programmatic advertising industry today. The list covers DSP vendors only; agencies or businesses running white-labelled DSP solutions are not included.
What Is a Demand-Side Platform (DSP) and How Does It Work?
A demand-side platform (DSP) is an advertising technology (AdTech) platform that allows media buyers — advertisers and agencies — to create and run advertising campaigns across thousands of publishers.
DSPs are a key component of the real-time bidding (RTB) process, which enables advertisers and agencies to buy inventory from various ad exchanges and SSPs on an impression-by-impression basis through a single user interface.
To improve targeting and enhance media buys, DSPs often utilize data from data management platforms (DMPs).
Main Components of a Demand-Side Platform
While each DSP offers slightly different features and functionalities, most share a common set of components:
