Best mediation platform

Hi people, how are you?

I have an app publisher of about 10 million download and i used to use only admob but eCPM fell a lot in the last days.

I am testing and getting very good results (even a bit better than appodeal/mopub) but I don’t know this company. Is anybody here using them? Do they pay on time?

Mobile Ad mediation is a technology which is used for sending advertising requests to a number of ad networks, ensuring that mobile publishers are able to fill their ad slots by finding the best available network. Right now i am using Alphagravel mobile ad network
