Here is an interview with Rob Leathern, CPMa CEO on AdExchanger.com.

One point buried in there is useful to reiterate:

CPMa’s goal is to get every online marketer who is buying search to at least do some display advertising in the form of retargeting. We’ve created a quick self-service way for them to do it with a credit card at http://cpmatic.com that allows them to create their pixels, set up their campaign and everything without having to talk to a salesperson or fax an IO – the ROI is fantastic as you know, but volume can be low so reducing overhead is key.

We believe that setting up a retargeting campaign on CPMatic.com is simple – (just chose “retargeting” as the campaign type and create your pixel) but try it and let us know what we can improve. More info about retargeting here.
