Definitely not. Not because of my partner, but because I wouldn't be comfortable joining that kind of venture as an employee. In fact I've walked away from job-offers in the past when I found out that it was a husband-and-wife team running the show. As an employee I need decisiveness and absolute objectivity in my leadership. I need to know that there are no other factors at play when they make decisions that affect the company and staff. It is certainly possible to run that kind of mom-and-pop shop (one where there is a wall between business hours and home-life)...but as the leaders of that company you two will be the only ones who know you're really being objective. Everyone else will need to take this claim on blind faith, and that's just too much to ask in most cases.
