But a launch is nothing more than a free way to get some traffic. Sure it doesn't guarantee conversions, but you'd be foolish to avoid free marketing for your startup. Instagram’s app reached 1 million downloads in less than 24 hours (and 5 million downloads in just six days). Apple's iPhone launch went pretty well too. Don't blame the press for lack of market fit.
Edit: you've made things harder on yourself by trying to invent a new product category. The iPhone was a better phone. Instagram was better than Facebook at photo-sharing. Are you sure the world needs a social network for families? If you ask people (especially investors) nobody will say its a crap idea because then you're viewed as the guy who doesn't want to share photos with his family. Well I don't. And neither do the girls on Instagram that have thousands of followers.
I've seen a few failed attempts at vertical social networks (soc nets for pets, families, etc) and none have been successful at establishing a new product category. Perhaps it's like "email for families" - there's no point for a completely new identity. Social networking is like email - its a set of tools (photo-sharing, commenting, posts). Instagram improved one of those tools. That's a functional approach. Trying to apply the same tools in a niche just means "messaging for families" to me. I understand families is the biggest use case of EveryMe probably, but WatsApp had the group messaging feature like forever and I've only seen anyone ever use it once. Group messaging never seemed to be a popular product category, and not one of the top things to do on Facebook (unlike photo sharing) so it seems like the market doesn't need a standalone app for that.
