Following years of slowed growth, ride-sharing app Uber may soon be forced to start selling its vast amounts of user data in order to turn a profit.

The company has been affected by a number of scandals in recent years, as a result, its growth rate slowed to 2.3 percent in the fourth quarter over the previous quarter, making the company’s annual loss of more than $3 billion all the more worrisome for investors.

Nowadays, there is no evidence the ride-hailing business is profitable, according to Steve Blank, a Silicon Valley entrepreneur, Stanford University professor, and startup adviser. He is wondering where the next billion dollars is coming from.

Uber has a wildly successful data collection on who uses its services and how they use them and where they go, notes a person familiar with the business, who declined to be named. All of this data “can become profitable,” the person claims.

Uber had to pay a $148 million in a U.S. settlement a few months ago after a cover-up of a data breach in 2016. Due to the data breach over 25 million Americans unencrypted names, email addresses, and driver’s license numbers were exposed, according to the Federal Trade Commission.
