John Cutler is a product evangelist and coach at Amplitude, and patron saint of product managers around the globe. Our PM Stef describes John like this: "Ever since I grew into product management from interaction design, I came across Medium posts of John and started following him on Twitter and became an avid follower. If you’re working in product, you will most certainly have come across tweets, medium posts or seen John talk at product conferences. Or you might even be subscribed to his personal newsletter ‘The Beautiful Mess’." This interview includes discussions on The North Star Metric, user validation, roadmapping, how to think about new technologies and the evolution of product management.
