This is a stupid idea...
Who would rent their home to strangers?
Who's gonna fund this???
It was BRUTAL. They launched what they thought was a great idea and got their rear ends handed to them. If you're in their shoes, what do you do following the launch?
AirBNB kept going...
Things got so bad that they were LITERALLY - VERY LITERALLY down to eating dry cereal in order to stay alive. As the folklore goes, they guys agreed that when all the credit cards were maxed out and all the cereal was gone, they'd go find real jobs... That never happened. And again... Today, AirBNB is worth $24 billion.
AirBNB tasted a very very tiny piece of success. Their model worked in a very unsophisticated way...They handed out some flyers, got some people to rent their homes, and went on to say; "let's make this a company." Keep in mind if they didn't make those pennies and create that magic initially, they would have been fools to continue to keep going. So folks sitting on ideas that you're scared are "too dumb" to try... Go get ONE PERSON to pay you for that idea. Or, go get one person to promise to pay you for that idea. Then - when that succeeds, keep going no matter what. Forget what others think!
