I think it depends on the faults you're talking about. If those faults in any way impact the business, then it's going to seriously affect how you view him as both a business partner and a friend.

In any case though, you're in a relationship with someone and communication is important. Your co-founder and you should be constantly providing each other feedback in order to be better partners. Be sensitive on how you word it when you bring it up, but if you stress that it's for the good of your friendship AND the business you've started, he should be able to take it in stride.

Thanks for taking the time to reply. I can be hypercritical and thought that maybe I just needed some time and space away. So that's kind of where I was going, but...

You bring up a perspective I need to consider. Some faults are simply part of his character and have come up in non-work related settings. Others have revealed themselves through work disagreements.

But you are right in that I should communicate what is impacting work. And try to do it in a way that won't sound like I'm just blasting him. He is a good guy after all.
