Sweden's next generation of entrepreneurs: Meet the Klarna mafia

Sweden's fintech scene is thriving, buoyed by a wave of ex-Klarna employees that are now founders themselves

In 2005, from a tiny back-office in the Swedish capital, three young post-graduates created Klarna; a company that has gone on to become Europe's most highly-valued fintech.

But that's not all they've created. Over the past 15 years, Klarna has also bred a wave of top-class engineers and managers that are now becoming founders themselves.

It’s part of a growing trend across Europe where one tech success story breeds a new entrepreneurial ecosystem of ex-employees.


In London, there's already a burgeoning Monzo and Revolut “mafia”; as well as a TransferWise mafia. The concept of startup “mafias” originally spawned from PayPal, whose employees went on to found Tesla, LinkedIn, Palantir, Square, and YouTube.

Klarna's alumni now counts dozens of founders, as well as prominent investors, such as Linda Samlin Höglund at Luminar Ventures, Mikael Wintzell at Wellstreet, Louise Samet, and Matthew Riley at QED. 

This has helped fuel the cycle, with "Klarnauts" occasionally receiving financial support from their former colleagues (including from Klarna boss Sebastian Siemiatkowski!).

Meet 10+ Klarna employees-turned-founders, hoping to leave their mark on Sweden's entrepreneurial scene — particularly in fintech.

Venture? Bringeus founded the only 'non-fintech' startup on this list, ASKET — a men's clothing range focused on sustainability. It boasts initiatives including 'The Impact Receipt', showing the environmental impact of each garment, and a single, timeless collection.

State of venture? The fund is active, but currently is performing below the average Swedish mid-sized stock.

More on their way

The Klarna mafia is clearly already well on its way. But it's predicted to keep growing, given the company's plans to list publicly in the coming years.

"[Big exits generate a] positive feedback loop in which capital, talent and education are reinvested into the ecosystem, shortening the time from creation to exit and reducing the risk of potential failures," says Alexandre Dewez, an associate at France's Idinvest.

"Successful mafias are growing on the back of [public] companies with a radical culture of entrepreneurship and ownership.'

With any luck, this could also encourage more female founders to come out of Klarna. It might even help narrow the gender gap in the Nordics, where female founders received just 1.3% of VC funding last year.

There's a particular shortage among financial startups, with women making up just 6% of CEOs of fintechs in Stockholm.
