How can I pick the right startup cofounder?
First, it is important to know what you do not know. You have to understand that your co-founder's job will be just as difficult as your job, but with a different set of challenges. Second, it's a good idea to really get to know your co-founder before commiting for a very long journey.
When Matt Oppenheimer and Shivaas Gulati were first talking about working together, for example, they spend a few days over at Matt's place in Boise, getting to know each other and really figuring out if they could work together.
