I recently wrote a post about funding for investors to think about having a diversified portfolio, which I called “shots on goal.” The thesis is that before investing in an early-stage startup it is close to impossible to know which of the deals you did will break out to the upside. It’s therefore important to have enough deals in your program to allow for the 15–20% of amazing deals to emerge. If you funded 30–40 deals perhaps just 1 or 2 would drive the lion’s shares of returns.
