Has anyone try ?assiveimpact ?nd what can tell us about?

Nope - haven’t tried them before. But I got an email from them asking if I’d like to sign up, shortly after you published this post.

Looks like they’re another network offering a mediation platform in order to achieve ~100% fill rate. Seems to be the way ad networks are headed these days - push your own inventory, as well as integrating with other networks as a backup plan.
