The 5 Travel Companies in the Billion Dollar Startup Club

This morning the Wall Street Journal published a list of startups valued at $1 billion or greater, and then turned to Twitter to tweet out each entry, one by one.

To save readers the time needed to comb through the list of 70+ entries, we've pulled out the five travel brands included in the list.

The travel entries are dominated by e-hail transport companies, with the U.S.'s Uber at the top -- it ranks only second overall in the Journal's rankings -- and Ola Cabs of India and Grabtaxi of Singapore near the bottom. Uber has had no challenges raising money over the past year. Just yesterday it expanded a round from $600 million to $1 billion in order to accommodate investors eager to take part.

Airbnb is also near the top, overall, sandwiched between Indian e-commerce giant Flipkart and cloud storage provider Dropbox. Also included in the list is Deem, formerly Rearden Commerce. Launched in 1999, Deem manages a platform to sell travel and related services for corporate travel clients including American Express, Carlson Wagonlit Travel, and Travel Leaders, and competes directly with SAS's Concur.
