There's a friend of mine that I think I'd really like to have on our team, specifically as an exec. I've known him for years, he's already got one startup under his belt (as a founder) and he's got a good head for business.
I'm debating how to pop the question. I asked my current co-founder via email, since I knew we'd see each other that day and wanted to give him some time to think about it. How'd you guys do it? Any particularly funny / successful / horrible experiences?
Edit: I should have been more clear in the original post based on some of the replies: We're already several months in and in beta, so we're not at the "I have an idea"-phase, but still pre-money. This is someone I'd like to come in since I think he'd round out the experience that the two of us have.
