“Ignorance is bliss,” Isaac Testerman says. “Everything we did was taking the bull by the horns, not knowing if what we were doing was the best way to go about it. We were just doing things the best we could.” After making his first short film with zero filmmaking know-how, Isaac went on to cofound Delve, one of Facebook’s lead creative agencies. Now, seven years later, what Isaac and his team lack in formal training, they make up for with gusto and experience.
