Those don't sound like differences in values, they sound like differences in experience. Namely, he sounds like 99% of new-founders, you sound like an experienced dev. Your values seem aligned: * You both want a strong product * You both want to actually earn money with it * You both want to serve your customers well * You both want to do the hard work now so that you're set for the future This is great, and I think what you're going through is very natural (par for the course really). You have 2 options really: * Step back: Let him call the shots for awhile, follow his vision for the product pipeline. Maybe he'll learn from his mistakes. (Or maybe he'll surprise you and come up with a solid plan). * Step up: Let him know that you're the defacto PM here, and he needs to start deferring to your experience. You write the roadmap, he helps you execute. Either was is fine, it's only really uncomfortable where you're in that weird middle-space you're in now.
