Without knowing exactly what your app does I'd say before taking funding or flying to SF you should start to get some kind of traction or a beta going with a user base to learn from. Also sounds like you are unsure how to market your app. If you need a certain size user/content base before your app is interesting you have an engagement wall problem. It might be a good idea to push installs by buying ads (twitter, facebook, etc.) on top of influencer marketing.
