Airbnb

Today, Airbnb is valued at more than $25 billion, and that number is seemingly growing every day — but it wasn’t always this way. The super-disruptive start-up’s early days were rough. When the company first launched in 2008, investors were having none of it. In recent interviews, founder Chesky discusses the seven prominent Silicon Valley investors who turned Airbnb down. He even shares screenshots of the rejection emails they received. (Who’s laughing now?)
