Remember that startup that was looking for a cofounder by spamming Craigslist?

They’re back. It seems they found someone, but it didn’t work out so well.

Brad Feld asks how many founders do you need to be a success?

I just looked through the companies I’m currently on the board of. The number of founders range from 1 to 4 with a concentration of 2 and 3. The few companies that have single company founders paired up with an experienced entrepreneur as CEO early in their life.

Finding a co-founder for a startup can be a tricky proposition. Unless you have a lot of capital to hire help early on, you’ll probably want to find someone to work alongside you from the beginning.

Your co-founder will need to share your vision and passion for your idea. If they don’t share the dream, they’ll lose focus and interest when things get tight.

They’ll need to have skills and a personality that compliments yours. There will be plenty of disagreements and hardship in the early days of a startup and adding to it with personality conflicts is just asking for failure.
