How AirBnB Became a Billion Dollar Company - Dave Gooden"Yesterday AirBnB announced that they raised $100M at a $1B valuation. This is a huge, huge accomplishment – but a lot of entrepreneurs are probably asking how they did it. Was it their awesome design? Excellent idea? Was it their uncanny business acumen? Just dumb luck?
My Answer: Craigslist Spam!
I believe AirBnB used multiple gmail accounts to spam craigslist and grow their site to a one billion dollar valuation."
