Thanks to a new partnership with Overstock.com, Klarna has come to America.

Starting today, customers at Overstock.com will be able to use Klarna Checkout for mobile online purchases. Klarna’s one-tap technology helps remove friction at checkout. Overstock.com CEO Patrick M. Byrne said that the solution has increased conversion rates during testing. CEO of Klarna North America Brian Billingsley called the partnership with Overstock “a massive opportunity to turn more browsers into buyers.”

Klarna’s technology allows online consumers to buy now and pay later. By partnering with more than 50,000 merchants and 35 million total end-customers, Klarna has become a leader in after-delivery payments in Europe. The company’s solution assumes both credit and fraud risk, speeding up checkout, making it safer and guaranteeing payment for the merchant.

Klarna has had an active 2015. The company hired a former American Express executive as its new chief commercial officer in June, and just a few months later, Klarna’s CEO Sebastian Siemiatkowski was named to Hot Topics’ top 100 fintech influencers in August. Klarna earned profiles from The Financial Times and Business Insider this summer, and spent the spring “experimenting” with bitcoin and winning bronze in the “Most Disruptive” category at the PYMNTS Innovation Awards. The company began the year joining 21 of its fellow Finovate alums in the FinTech50.

Founded 2005 in Stockholm, Sweden, Klarna made its Finovate debut at FinovateSpring 2012 in San Francisco.
