Well, somebody must. In 2014, AirBNB, the service that helps people rent out rooms in their home, “sold” more than 40MM room nights.
This included rentals in every country of the world except four: Cuba, Syria, Iran and North Korea. (In early 2015, they had their first Cuban rental.) This is more room nights than Marriott or Hilton. But unlike these big hotel chains, AirBNB did this with no fixed assets and 60 employees. Think of the ROI! In fact, frequent users of AirBNB use this product to pay about 60% of their home mortgages. AirBNB continues to grow at 100% per year. This might be slow, of course: Uber continues to grow at more than 300%.
