Just how fast has AirBnB grown on the supply side since its formal launch six years ago?
I compiled public data around AirBnB's growth of cumulative total active listings over time. It took AirBnB 2.8 years to reach 120,000 active listings and another year to reach 300,000 active listings. In the first 10 months of 2015 alone, AirBnB total active listings have jumped to 1.8 million from 1 million in December 2014. Put another way, AirBnB has added 233% more listings in the past 5 months than it did in its first 2.8 years of existence.
