LB Finanzas: +447% users acquired at half the cost per acquisition
LB Finanzas is an Argentine fintech that needed to scale its user base efficiently while competing against larger players. Over five months, we fixed web-to-app measurement, optimized campaigns by performance, and added new channels. The outcome was +447% growth in paid-acquired users, a 53% drop in cost per user, and an 80% improvement in signup-flow conversion.
The challenge
LB Finanzas was competing in a segment where larger players carry substantially bigger advertising budgets. Growing required spending smarter, not just spending more.
- Measurement gaps between the web and app environments distorted attribution and made campaign decisions unreliable.
- Creatives and messages were not being evaluated systematically for their actual impact on user acquisition.
- The channel mix was narrow and did not include app-install formats, leaving a meaningful slice of high-intent audiences unreached.
Our approach
We worked across four areas directly tied to the friction points limiting growth: measurement, creative, audience, and channels.
- 01
Web-to-app measurement and attribution fix
We identified and resolved the tracking gaps between the web environment and the app so that every conversion was correctly attributed. Without a reliable measurement foundation, any subsequent optimization is guesswork; this was the first step.
- 02
Performance-driven creative and message optimization
We iterated on creatives and messages using real performance signals. Each adjustment was data-led: which format, which copy, and which value proposition resonated with users who went on to complete the registration flow.
- 03
High-intention audience segmentation
We refined audience targeting to concentrate budget on users with a higher probability of converting and remaining active inside the app, rather than optimizing purely for install or click volume.
- 04
New channels, including Facebook App Installs
We expanded the channel mix by adding Facebook App Install campaigns, a format designed to drive users directly to the app. This extended reach to audiences that were not being captured by the existing channels.
