A Demand-Side Platform (DSP) is the technology that lets advertisers buy digital ad inventory programmatically — across websites, apps, video platforms, and streaming services — all from one place. Instead of negotiating with individual publishers, a DSP finds your audience at scale and bids on the right impressions in real time. DV360, Amazon DSP, and Adform are among the most powerful DSPs in the world. We give you access to all three.
