Great way to visualize skillset match for co-founders, I however feel that this isn't isolated to doing a startup with a spouse but with any co-founder choice; making sure you have the right skill balance.<p>Since starting backstitch (<a href="http://backstit.ch" rel="nofollow">http://backstit.ch</a>) with my wife we constantly get this question: "How do you work so well together?" We really don't see it different than if we were just two best friends from college that decided to start a startup.<p>We were used to working together on projects in school and post graduation weekend hacks. Our careers led us to work on different things and pick up different expertise (font-end design vs operations vs data analysis, ect.) Yes you need to consider thing such as establishing a work vs personal relationship but the same is true when going into business with a close friend as many people do.
