As others have already mentioned, the post is a bit vague on details. However, what is your role? Are you the CEO or the CTO? Why is your cofounder able to steer the company? Higher stakes? Your silence? Extrovert/introvert issues? Did you happen to detail your cofounder why their chosen path is not good for the company? Do you have a structure in place to resolve cofounder conflicts? Do you still have your heart at that place? How do you know you are not mistaken/your cofounder is heading in a wrong direction?
