In digital advertising, the right tools can make all the difference for a campaign. Along with the best supply-side platforms, demand-side platforms (DSPs) have become the cornerstone of programmatic advertising. They help marketers buy digital ad inventory automatically and target their audiences with precision. But with dozens of DSPs available, how do you even decide which are the best programmatic advertising platforms?
In this guide, we’ll take a look at the top 5 demand-side platforms in 2025. We’ll discuss their key features and who they are best suited for. Without further ado, let’s start with the basics.
Defining DSP: Why Does It Matter in 2025?
A demand-side platform is a software solution designed to help advertisers purchase digital ad inventory on multiple platforms. These could include websites, mobile apps, video, and more, all accessible through a single interface. DSPs use real-time bidding, enabling them to bid on ad space in milliseconds.
Just like the top SSP platforms, DSPs are smart, AI-powered ecosystems. They don’t just deliver ads; top options of DSP platforms can help to:
- Interpret behavior.
- Optimize budgets.
- Ensure brand safety.
- Help businesses comply with global data protection laws like GDPR and CCPA.
Maybe you’re a marketer who’s planning a display campaign. Or, maybe, you need to stream a video ad or plan native promotion. Whatever the case is, a good DSP from top programmatic AdTech companies can help you squeeze the most from each dollar you spend.
With that being said, which platform should you actually choose?
