Ask HN: Built an app but don't know how to take it to the next phase

I just spent the last year and a half building an iOS app, an idea that I have a lot of passion for. It's a social app, so the next step is quite the obstacle for me, I don't really know how to go about pushing it to the market. Its content requires a decent size user base so I've been considering trying to get some funding for help.

I haven't released it to the app store yet.

I've made a video demo of the app and have thought about sending it to....

questions:

-what direction should I go from here with these presented circumstances?

-would it be risky to send someone the video who has a lot of money and resources?

-should I fly out to san fran and start knocking on doors?

-should I scrap my entire plan and just try to do it myself?

Any advice would be greatly appreciated
