When Sequoia Capital invested in Whatsapp, the venture capital firm didn’t know that within a short couple of years, the company would be sold for $19 billion (!). What they did know is that the firm employs a repeatable process to screen, diligence, and invest in high-powered startup companies in order to invest in what portend to be future billion dollar companies. There’s no doubt that this process has made the investment team — and its investors — very rich over the past couple decades.

And now, as equity crowdfunding platforms like OurCrowd are proliferating, individual investors are getting the opportunity to make their own investments in the next Google, Facebook, and Apple. There’s a lot to understand about the angel investment process: from how it works to understanding terms sheets to exiting your investments successfully. With this end in mind, I put together a list of some of the best resources to learn more about investing in startups.
