Agree, absolutely. If I didn't know my business well enough to close our first partnership with the top 4 US health insurer (paying) to develop an app we designed that will generate two patents, I'd bow out. We've closed a 5k deal, another 10k deal on the books about to close, and taken only 10k in angel money. That's not only understanding the company, it's understanding where the company is headed, and then working with my tech cofounder to implement like crazy til we get there. Plus, 'tech' of any type is a means to an end. One founder working on the tech and one founder working on the rest of the stuff that forms the means to the 'end' isn't always a recipe for disaster.
