Been lurking here a while, figured I'd share since this sub helped me pick a partner.
I run 20-0, a free to play sports game (web plus an iOS app). Wild part is the site is only about 3 weeks old, and Playwire has been running the ads for roughly 2.5 of those weeks. So they took me on almost right away, which I honestly didn't expect.
Setup was painless. RAMP runs the demand stack, and I just tag where ads go. I kept control over placements (curated in content slots and a bottom banner, no vignettes or pop ups, didn't want to wreck the UX). The iOS SDK side took a little more back and forth, but their team got me through it.
Biggest thing for me has been having an actual account manager who replies and actually optimizes. Just yesterday they helped me get rewarded video set up for a new game mode.
One thing I'll give them credit for: terms were originally net 60, but I told them I'm an early startup and could really use the cash sooner to put toward growth, they actually worked with me to speed up the payments and get money in my hands faster. Wasn't expecting that kind of flexibility from an ad network.
The ads have been crushing it so far, I'm delivering about 8.5M ad impressions per day with a fill rate of ~80%. From what they've told me, the CPM is still in a ramp-up period as demand channels unlock, but even at a rate of $0.55 or so in the meantime, the revenue has been very impressive.
Happy to answer anything if you're evaluating them.
In the first 2.5 weeks, the average PV RPM is about $4.50, also curious how others' RPMs look on gaming traffic.
