The absolute BEST time? Would probably have to be a). Preferred times are b). Worst time is c) and beyond I've only had experience working with my one childhood friend whom I've co-founded all my projects with. We've worked together since we were kids, building dinky static web pages with Dreamweaver. So I've never had the experience of bringing on another co-founder, or working with someone I didn't have an extensive history with. The reason I think its A) is because its not quite as important as to WHEN your co-founder joins, but WHO you co-founder actually is. A friend or someone you've worked with in the past is someone you can trust. Someone you can trust is someone you can bounce ideas off of and have "chemistry" with. The sooner the two of you have your brains firing off and inspiring each other with a concept or product, the better. This means you can argue sooner, and shape out what it is you want to build far more effectively. Ideas will constantly change, but the person you're stuck with will not. So the sooner you find the right person, the better!
