Rap icon Snoop Dogg is an investor in Swedish fintech Klarna and has dropped a video to alert his millions of fans.

The hip hop superstar launched a one-minute video, The Coronation of Smooth Dogg, which will be used as the company's ad campaign on television and in movie theaters.

 "We are building strong momentum in the U.S. with both merchants and partners and continue to grow," Aoife Houlihan, vice president of communications at Klarna, told Mobile Payments Today in an email.

"The recent launch of our new offerings there of Pay Later and Slice it 4 have been received super positively and we are very much focused on [the] smoothest shopping experience and giving consumers flexibility and service at the till, which they have come to expect."

Houlihan said the company is not disclosing details regarding the amount of the investment.

Klarna, founded in Stockholm in 2005, offers e-commerce retailers the ability to offer installments, pay after delivery and operates a licensed bank. The company's other investors include Sequoia Capital, Bestseller, Permira, Visa and Atomico.
