My suggestion to get a sense of why having a cofounder makes sense is to just try it. Find someone interested in startups you like being around and pick a problem neither of you are currently working on. Each work on it alone for one day for a set amount of hours, then the next day, work together.
After doing that, you might try bring on a third "cofounder" to see what that's like.
Point is that there's a lot you're able to read about the topic, everyone has an opinion about it, but only way you'll get a feel for it is by seeing what it's like working alone and with cofounders.
Make sense?
Looking for a cofounder that's interested in applying to YC for this batch.
Only requirement to get started are that we work together on the startup 20+ hours as a team before pressing submit.
Happy to work on your startup, mine, or build one based on YC's existing open requests for startups.
