How do you shortlist DSPs when half of them claim to do everything?
Agency side running media for a handful of D2C and ecommerce accounts. Every time we scope a new platform the shortlist gets longer and less useful.
Mobile stopped being its own category a while ago. The big omnichannel platforms all cover in app, mobile web, display, video and CTV, and mostly they do what they say. The mobile first ones sit closer to app installs and post install events. On paper the difference is clear. In a pitch deck it isn't.
Our current process is to define the use case before looking at any vendor, so app UA and retargeting go down one path and CTV plus omni channel go down another. That beats hunting for a master list, since platforms merge or get shut down constantly and plenty of them are region-locked or enterprise-only.
Measurement breaks the comparison though. Two platforms can both claim CTV support, one gives placement-level reporting you can act on mid-flight and the other gives a monthly impression summary. That gap matters more than the inventory list and it never comes up until you're already spending.
So what filter are people using at shortlist stage?
