Unicorns.

The most overused word in startup and tech circles these days, unicorns are private companies valued at $1 billion and above by investors, primarily venture capitalists and growth equity investors.

CBInsights, the business information service that tracks private companies and investors, has been keeping a live list of these unicorns from around the world, and as of last count, about 142 of them exist.

Out of these, we decided to sort through the ones that are travel companies or have major business in the travel industry, and we counted 15 of them on this list. As you can see, most of them are focused on disruption taxi/private transportation sector.

Uber is the most valuable private company, not just in travel but amongst all private companies anywhere in the world. Airbnb is the second most valuable company on this list. Deem is the only business travel company on the list, focused on expense management. Eventbrite is the only meetings/event tech company on this list. Decolar is the only traditional online travel company/OTA on this list, focused on the South American market.

Geography wise, U.S. headquartered companies top the list with six, though almost all of those are global businesses. China is second with four companies on this list, all of them focused locally.

As for the investors, Accel Partners seems to have the biggest stakes in these travel unicorns, with Sequoia, GGV and Tiger Global being other prolific investors.
