In mobile adtech you have two giants (Google and Facebook) and 5-7 major competitors, which we've called titans, and then hundreds if not thousands of additional ad networks.

In this episode of Growth Masterminds, cross-posted from TechFirst with John Koetsier, we chat with Unity CEO John Riccitiello about why he pulled the trigger, and what Unity expects to gain by acquiring ironSource.
