Uber is buying Berlin-based startup Blacklane, which provides on-demand, black-car chauffeur services, as the ride-hail giant expands deeper into luxury and executive travel services.

It’s a notable exit for Blacklane, which was founded in 2011 and has raised more than $100 million to date from rental car company Sixt, Mercedes-Benz, and ALFAHIM, a conglomerate in the UAE.

Uber said the acquisition still needs regulatory approvals, but expects it to close by the end of this year. The two companies didn’t disclose financial terms of the deal.

The acquisition comes just a few weeks after Uber announced the launch of Uber Elite, which combines a chauffeur service with a number of luxury offerings like in-vehicle amenities, airport meet-and-greets, and 24/7 phone support. Uber Elite is starting small, in just Los Angeles and San Francisco, with New York City on the horizon. Blacklane operates in major cities across Europe, the Middle East, Asia, South America, and North America.
