What is demand side?

In plain terms, demand side is how a team keeps the work organized in one shared system rather than across disconnected files and tools. Demand Side Platform (DSP) is that system.

Most teams feed a demand side tool from several sources and organize the data so it's easy to act on. From there it automates the repetitive parts — routing, reminders, and status updates — cutting manual effort and errors.

The result is a single, real-time view of your demand side. StackAdapt, The Trade Desk, and Choozle take different approaches — some focus on simplicity, others on breadth — which is exactly what the comparison below is built to clarify.
