"If you launch and no one notices, launch again. We launched three times."
— Brian Chesky, Founder of Airbnb
I don't think there's a right and wrong way to launch a product, but you CAN re-do it many times!
Brian Chesky of AirBnB apparently re-launched AirBnB 3 times before it took off.
Launch 1, 2007:
To pay their rent AirBnB founders put air mattresses on their floor and offered them to attendees of a design conference. 3 bookings.
Launch 2, 2008:
They revamped the site and launched it again at SXSW. It resulted in only one booking.
Launch 3, 2008:
They re-launched again when a big convention was in town and hotels were sold out. Resulted in 80 bookings!
