Brian Chesky, CEO and Co-Founder at AirBnB, recently published 7 rejection letters he received from valley VCs in an effort to raise $150k for a 10% stake in AirBnB during mid-to-late 2008. My own view into that era was already published in an email thread between Paul Graham and Fred Wilson that shows how easy it is to miss deals at the earliest stages (I was in the USV pitch mtg with Fred for AirBnb that is the subject of that thread).
