Danish-born computer scientist Lars Rasmussen, the co-creator of Google Maps, is launching a music start-up.

Rasmussen has announced that he is leaving his latest employer, Facebook, to co-found a music startup with his partner, Elomida Visviki.

According to TechCrunch, Rasmussen will leave Facebook in June.

“Leaving Facebook was an incredibly difficult decision,” Rasmussen said in a statement.

“Working there has never been more exciting for me, in particular given the incredible momentum behind Facebook at Work, and the ridiculously talented people I work with on that project and at Facebook in general. But over the past year my fiancé, Elomida, has built what I think is a new and exciting way to compose and experience music.

“And trying to turn that into a successful startup together will be way too much fun to postpone any longer.”

An Engineering Director as Facebook, Rasmussen has recently been working on Facebook For Work – the social media site’s enterprise tool.

He joined Facebook in 2010 after playing an instrumental role in creating apps for Google, including its Google Maps platform.

“We are grateful for Lars’ many contributions over the years,” a Facebook spokesperson said in a statement.

“We’re a company of entrepreneurs, and now that Facebook at Work is off the ground and growing quickly we understand Lars’ desire to return to his startup roots. We wish him the very best.”

Lars Rasmussen’s new life as an entrepreneur will be based in London. [Music Business Worldwide]
