The Challenge
Discover’s credit card division oversaw a significant national media budget but lacked a unified, performance-driven GTM framework. As CAC climbed and performance varied across offers and channels, it became increasingly difficult to scale predictable growth—particularly as customer acquisition teams lacked cross-channel attribution, testing velocity, and downstream clarity on LTV.
The Strategy
Signal Growth’s founder implemented a data-first, segmented performance infrastructure to bring precision and accountability to Discover’s card acquisition efforts:
- Launched multi-product, multi-channel GTM campaigns across addressable TV, programmatic display, search, SEO, paid social, direct mail, and retargeting ecosystems
- Developed modular creative frameworks and offer matrices tailored to financial behaviors, credit tiers, and customer lifetime value cohorts
- Introduced a robust A/B testing engine paired with analytics dashboards that tracked conversion, retention, and LTV by segment and source
- Rolled out channel attribution standards and rules-based budget allocation to move funds toward top-performing verticals in real time
The Results
- Achieved a 300% increase in open credit card accounts, distributed across strategic customer profiles and segments
- Reduced CAC by over 50% through intelligent media mix modeling and offer-level refinement
- Tripled Discover’s net-new cardholder acquisition volume while maintaining compliance and profitability standards
