2005 2007 2008 2009 2010 2011 2012

The vision of safer and simpler e-commerce was born. Our founders introduce an idea: Invoice, that will change the way people shop online.

Klarna’s journey

The 1000th store is signed. Investment AB Öresund becomes a partner in the company. We expand and offer Finnish, Norwegian and Danish consumers our payment solutions. We also introduce our second payment service, Account. To expand further we need a company name that is viable for more than just the Nordic countries. Therefore, we change our name to Klarna. Klarna is growing and expanding rapidly by establishing
  • urselves in Germany and the Netherlands. We also launch our
third payment service, Klarna Mobile. Michael Moritz joins the board and we receive an investment from Sequoia Capital. With ~770 employees and growing, a new product: Klarna Checkout and Austrian market entry, the future is very bright. Klarna receives financial backing from DST Global and General Atlantic. We were nominated as Best International Startup in the Crunchies Award. torsdag den 7. marts 13

keep it simple for the user (not engineering)

  • no pre-registration
  • identify yourself using top of mind

information

  • separate buying from paying

software engineering is about cost efgectiveness and lead time.

  • In a realm where every business has the same requirements, shrink-wrapped software
is appropriate. E.g. excel, SAP.

  • In a realm where every business has the same requirements, shrink-wrapped software
is appropriate. E.g. excel, SAP.
  • In a realm where many businesses face the same problems, but there's a lot of
business-specific tweaking, the Java ecosystem is hard to beat. E.g. camel, hadoop,
  • racle.

  • In a soft-realtime, business specific realm, in-house development in something as
funky as Erlang is a great choice. E.g. telephone switches, stock quote distribution, financial transactions etc = core stufg where you need to own your code & know your tools.
