Do you actually have an app? If so, can you talk about it at all or send demos? I, and I imagine many others on HN, could directly fund the project directly if the idea and execution are good.

If you are just asking the rhetorical question, it depends on whether or not the app requires a critical mass of users (ie social networking) In either case, your best bet is to publish and start discussing on a forum (HN is a great start).
