MediaMath TerminalOne Marketing OS™ Reviews in June 2026: User Ratings, Pros & Cons

MIGRATED TO Infillion

I used to work with Media Math at my previous agency, 360i.

What do you like best? They have a very strong product with a solid algorithm. Performance was driven and their contract/IO was renewed across multiple months. I also like that they have access to exclusive inventory and unique offerings. For example, we used to run with them across exclusive placements on FBX that other vendors simply couldn't access. I'm not sure if they operate a private exchange, but this would be a very nice feature of their product suite. What do you dislike? ...

Powerful DSP

What do you like best? MediaMath makes it very intuitive and user-friendly to do very powerful bidding and targeting in a well-designed interface. The team there is constantly taking suggestions from their users and making improvements to the system, which introduces new features on a fairly frequent basis. What do you dislike? It can be confusing for new users to differentiate between MediaMath's TerminalOne and Terminal One beta platforms - the transition was incomplete for a long time ...

Good product that just needs to work out some kinks

What do you like best? MediaMath is a very easy product to learn. What I really liked about it was that I could monitor campaigns across a variety of platforms and that I could easily pick websites that I wanted to run ads on. The exclusion feature was also fairly straightforward. The dashboard is really clean, allowing you to see all the ads and campaigns that are running. It was also relatively quick and straightforward to add creative. What do you dislike? The brain feature didn't ...

MediaMath works Great!

What do you like best? MediaMath is very advanced. They are truly pushing the envelope for what is possible with digital advertising. Activating complex first party client data was the most advanced that I have seen, the process and the eventual optimization. Complex segments were managed well and the reporting came out clean and understandable. What do you dislike? MediaMath is not cheap and I know they are taking a very healthy margin. Also I have some concerns about where the ...
