Silicon Valley is famous for its venture capital firms that manage large portfolios. We also have a large community of angel investors who invest outside of VC funds. You can reach hundreds of angel investors with a broad range of expertise and interests through Sand Hill Angels and the Band of Angels. Either group can fill a large portion of a round for pre-seed, seed, and series A funding for a promising company.
Also, the Angel Capital Association publishes a directory of local angel investment groups throughout the world.
I am usually happy to give feedback on your pitch if you connect through LinkedIn.
