Not sure about how many, but it can be as small as one or as big as 5 and up. I can build complicated software, websites, and I am well acquainted with design conepts. Find a co-founder who can fill in my weaknesses is perhaps what I'm looking for. And more importantly, we need have the same vision and passion for the startup. That is difficult because its hard to convince someone that your idea is worth the commitment. So my question is, how do people usually find that right co-founder/co-founders who can believe in your vision?
