AMA with Jorge Mazal
Former Chief Product Officer at Duolingo, Jorge Mazal takes us on his journey of reigniting growth by 4.5x at Duolingo. Get an inside look at how he approaches gamification, a/b testing, and the search for new growth vectors.
“One of the biggest wins that the team can have is discovering growth vectors. And once you have a vector stick with it. You can always squeeze more juice out of some of these vectors very fast through iteration and experimentation.”
