The team at cross pixel are very helpful, responsive to questions we have and eager to implement new features or fixes that may be needed in order help us reach our objectives! They also offer great value when it comes time for renewal pricing so you don't get stuck paying more than necessary. I haven’t found anything yet about cross pixl media specifically but working within their agency partner has been fantastic (in fact they recommended me!). We use them as an ad network platform across multiple platforms including Instagram where most of our business is generated from.
