Should I use Startapp to promote my app?

Is anyone using Startapp as an advertiser? Could you give me some reviews about the ad cost, conversions, CTR… of this ad network? Should I use it to promote my app?

I suggest that you try Appnext before you go to Startapp. With Appnext you have total control of the campaign and most importantly - your CPI rate. You choose the bid.
Let me know if you need more details.

Yup - we actually have some of their average CPI & reach data here: StartApp Advertising Reviews, Ratings, Pricing, Mediakits, Contacts, Traffic, Demographics, Reach, Creatives - Thalamus

You can also get contacts and reach out to their team if you’d like.
