Good agency in the US for new app launch (CPL/CPI/CPM, etc.)??
I'm working on a project to launch a new app in the US (something like Endomondo, RunKeeper, Runtastic...).
We are developing the ad network proposal and need to find reliable agencies/companies that could provide a good service to get us good CPL/CPI/CPM prices. Nothing "spammy".
Any suggestions? Thanks!
