Streaming music giant Spotify has announced that it has bought Paris-based AI startup Niland, making it the company’s fourth acquisition of the year. The French company will join Spotiy’s R&D team in New York to help them develop new personalization and recommendation features for users (via TechCrunch).

“Niland has changed the game for how AI technology can optimize music search and recommendation capabilities and shares Spotify’s passion for surfacing the right content to the right user at the right time,” Spotify said in a statement.

“We will keep working on new ways to better understand music to craft better innovative listening and discovery experiences,” Niland’s founding team wrote on its website.

Niland was founded in 2013 and had raised undisclosed funding from French investor IT Translation.

In 2017, Spotify has acquired blockchain startup Mediachain, content recommendation startup MightyTV and audio detection startup Sonalytic.
