Introduction
Klarna, the global digital bank and flexible payments provider, partnered with Rokt to enhance post-transaction engagement across its rapidly expanding international footprint, delivering tailored offers and content immediately after checkout. As Klarna expanded into 14 markets and included Rokt-powered offers in new touchpoints, they sought innovative solutions to deepen customer relationships, drive in-app engagement, and support strategic campaigns.
We have one hundred and eleven million customers around the world. We do three million transactions a day. The power of the Rokt partnership is the ability to make every one of those transactions for every one of those consumers more personalized, more relevant, more meaningful. And that's what I get very, very excited about. You know, we're in the business of payments, we're in the business of helping consumers make transactions, and Rokt helps us take that to another level with Rokt product. Hi, I'm David Sykes, I'm the Chief Commercial Officer at Klarna. We want to sit at the intersection of shopping banking and traditional finance. We really want to make it easier for customers to spend their money, to save their money, and really put them in control of their money. You know, we want to make sure that every consumer that uses Klarna gets an experience that feels relevant to them, feels personalized to them. Rokt's been a fantastic partner in helping us deliver on that consumer promise. So today we use Rokt Thanks, and we've seen, you know, really good engagement with that product, a fantastic consumer experience. One of the key impacts we've seen from the Rokt integration is that CTRs are above the average in the US. That's a really important metric for us. The other thing that we've seen and is really encouraging is double digit growth. So all of the indicators are really, really positive, it's part of the reason we've expanded to so many different markets is the success that we saw in the US. And you know, for us, I think it's probably just the starting point, you know, the confidence that that product has given Klarna, the success we've seen, you know, really encourages us to adopt more products, I and I think you're gonna see that in the future. One of the things that we love about the Rokt relationship is our ability to send signals to Rokt about the consumer, about their preferences, about their likes, their dislikes, and really have that inform and curate the offers that Rokt's AI presents to the consumer. That leads to higher attach rates, more contextualized offers, and ultimately a better consumer experience. That moment of making a purchase, you know, the consumer is so high intent at that moment. It's such a critical moment, not just for us, but also for the brands we work with. Making sure we had the right partner, the right offering was a really, really important criteria for us, and Rokt's now, you know, a very integral component of that that journey. For Klarna, we've unlocked a really attractive, scalable new source of additional revenue. And I think it's the fact that we can marry those two two outcomes, the better consumer experience and this, you know, sustainable, scalable new revenue stream for Klarna that's that's so exciting. What makes the Rokt partnership so special, I think, is the collaboration. The collaboration with the Rokt team. The feedback I have from my teams, my personal experience is that, you know, every touch point is is professional. It's enjoyable. There's a creativity there, which we love. You know, and I I I feel like there's a real sense of cultural alignment between the two businesses.
