I mainly focus on verification vendors (such as Integral Ad Science, Double Verify, Peer 39, Grapeshot) so I appreciate that MediaMath is integrate with (or is on the roadmap to be integrated with) these verification vendors. It makes us more likely to recommend working with MediaMath to agencies as a result of their transparency.
From a service standpoint, MediaMath is always quick to respond with questions that I have and provide relevant, up-to-date information.
MediaMath is also known for their robust integration list and strong targeting capabilities within my company.
I have not had a lot of experience of actually working with MediaMath's platform, but I have heard from other team members that the campaign management process is not very streamlined.
I do not have a ton of experience with MediaMath's platform, but have heard feedback that the campaign management process could be more streamlined.
Viewability, ad fraud, and brand safety are always a concern. However, since MediaMath is integrated with some of the big players, such as IAS, they are addressing this concern.
A big business problem my team is focusing on right now is channel expansion and we are seeing very few DSPs starting to tap into new channels, such as: Programmatic TV, Programmati Audio, Digital Out of Home (DOOH), and Beacons. While we understand that these channels are a little ahead of the curve, it would be nice to see some DSPs start to experiment with one if not all of these new channels.
