Some of the most fixable patterns are subtle. This diagnostic is for cofounders who can feel something is off in the partnership —whether it's been off for six weeks or six months, whether you're in active conflict or just sensing the drift. You don't need to be in crisis. You do need to be paying attention, if you want your partnership (and your business) to succeed.
