I'm sure she'll understand (and appreciate) your anecdote much more than I ever will. She's a big time trekie, and me? Not so much...
However, this still leaves my original question somewhat unanswered. While the three of us may be a great team, I've known many people who believe that couples should not work/do business together as they feel it will inevitably lead to conflict and result in the breakup of the company, relationship, or both. I'm sure that they have some personal experiences, but how does YC generally look at this type of situation. Will they see it as additional (and unnecessary) risk? Are there any examples of husband/wife teams in successful startups?
