Our Strategy in Action

Three key pillars that drove sustainable growth.

1. Localized Acquisition

We didn't just translate ads; we localized the experience. By matching regional preferences with platform-specific creative (TikTok's viral energy vs. Facebook's precision targeting), we ensured the brand felt "homegrown" in every market.

2. Feature-Led Conversions

We highlighted the utility of the app. By showcasing Klarna's installment plans as a financial tool rather than just a checkout option, we gave users a tangible reason to keep the app on their home screens.

3. Retention by Design

Success wasn't measured at the "Install" button. We utilized layered retargeting to push users from installation to first-purchase activation, resulting in a 28% retention rate,significantly higher than industry averages for fintech.
