The title is a bit misleading, but I constantly beg for non-technical colleagues to have any sort of application modelling skills. MS Paint Web Mockups, Excel, PDF Forms that save to an email 'database', anything that gives a clear picture of how things work. Huge bonus if the mockup actually functions. You don't need to invest in time learning Ruby or .net since the end result is communication. Actual execution is where the technical cofounder comes into play.
