Klarna has released financial results for H1’24 and CEO and co-founder Sebastian Siemiatkowski has indicated that the company is likely to pursue an IPO in H1’25. Revenue grew 27 % y-o-y in H1, with the US growing 38 %. Combined with cost cuts and layoffs, the revenue per employee has increased with 75 % to 7 million SEK in one year.

In H1 Klarna was growing a bit faster than Spotify (and yes, there’s really no reason to compare them except they’re both Swedish and successful) and are seeing similar improvements to profits from cost control.
Going public with 25%+ growth and significant margin improvements sounds like it could be a success.
