Ask HN:How to get introductions to the right Angels and Seed Firms

At the stage I need to start looking for capital. Located in the Midwest while I have connections here they aren't the right fit for my company especially since I know I'll need to move to NYC or SF. The few investors I've shown love the beta and my vision but agree I need to find the perfect fit (industry, experience, location, connections). While I have a list of a few angels and seed funds (ie First Round Capital) that should have an interest don't have any way of getting in the door. Short of a blind email that nearly never works.

The Midwest investors and VCs I know only deal in the Midwest and stay out of the social media area that I'm entering so they don't have the connections.

Planning on using AngelList. Anyone have any success using it to get the ball rolling?

What else have people done in my situation?

Any tips?
