Hello Jonny.
Yes, you are right, we worked on behalf of a larger app making company and we were dealing with apps monetization.
About half a year ago we launched our monetization programs globally. We pay for CPM, and you can choose any way of integration (SDK, JS tag, s2s). We have our own system similar to DSP and because of that we have high numbers and very good fill rate. We also offer 24/7 support for our clients.
Thanks and Welcome!
Alex from SilverMob.
