Also check out FundersClub and Microventures. Both have access to many of the hot deals in Silicon Valley due to their close relationships to the accelerators there, such as YC and 500S. It's a great way to get access to these deals, with investments as low as $2500. You can also try joining a local Angel group, but in my view these types of groups will be disrupted by platforms like AngelList and FundersClub. These platforms provide an easier and faster process for both the startups and angel investors.
