Exit Ads + MoPub. Is it possible?

Hello, first of all I’m new to the forum although I’ve been reading you guys for a while. Great job the one you do here.

I have one question regarding MoPub and Exit Ads. Do you know if is it possible to implement somehow? I mean, the “Exit Ads” like the ones of Startapp.

You would just display an interstatial on exit? Or is there any other way?
