I do find that some of the co-founders "ideas" are technically not feasible and this is causing some distress, when trying to explain it to them how things work. Both of the 2 co-founders are mid-to-late 30s, one is a doctor and one had successfully built and sold a company (although in an entirely different industry, a consultant recruiting company actually). Both of the founders have limited technical knowledge and I don't think they understand the iterative process that programming is, they don't understand about refactoring code and rewriting/etc...and so as soon as I create a new feature, they already want to move onto creating another feature without refining what we have They basically have a time-line of launching in March 2012, and we only started in May of this year. One thing that's worrying me is that I haven't yet done a second iteration of the code and they keep wanting more things added..and I feel that we're not focusing on solving one problem but many (too many). Products that are successful start off as being simple and then more gets added over time... One of the issues is that one of the co-founders is my Dad's former co-worker's Son, and even though I have some say now that I have equity, it won't necessarily be heard because what does a 22 year old know anyway, right? My suggestions might seem too radical to them, and that is to drop a bunch of what we have, and now that we've had some testers, to focus on what the testers liked, and remove what they didn't. Several of the testing sessions that we had, the people using this new service had mentioned that because of the relatively private nature of this service, that they feel uncomfortable with a linkedin/facebook login button on registration because they feel like the private information available on the service will be shared with other more public networks. My vote is to drop these "features" but the cofounders seem insistant that we keep them and feel that it "adds legitimacy" even though the testing sessions seem to show otherwise. There are other examples of this based on tester feedback, this is just one of them
