David Lerner, an entrepreneur, angel investor and researcher, has been on a roll lately,
publishing very useful papers on and resources for the Angel and entrepreneurial communities. Today I came across two articles of his that map the early-stage technology investor ecosystems in Silicon Valley and Boston. I have copied the Silicon Valley map below for reference, but these maps are better viewed from Lerner’s own websits, which I recommend you visit anyway.
These maps, initially started by Lerner, have been augmented by feedback from the investor communities in both areas and are a great tool for both Angels seeking potential co-investors in a specific region or entrepreneur seeking strategic investors for the same. Thank you, David, for this very useful resource.
