Editorial Team In fintech, getting users is a knife fight. For a platform like Cash App, you can’t just buy reach with social ads, you have to build trust, and that’s a much harder problem. Building both reach and credibility at the same time is the whole challenge.
Key Takeaways
- The “Cash App Fridays” campaign drove a 22% lift in new user registrations from social ad exposure during its 6-week run.
- Authentic user testimonials beat our celebrity creative by 15% on click-through rates.
- Using lookalike audiences from high-value customers on Pinterest Ads cut our cost per acquisition by 30% compared to broad targeting.
- A/B testing proved that ad copy mentioning security and FDIC insurance boosted initial deposit conversion rates by 10%.
- The $750,000 campaign budget delivered a 2.5x return on ad spend (ROAS), paid for by transaction fees from the new users we acquired.
In mid-2025, we ran a six-week social media blitz for Cash App, from May 1 to June 15, with a $750,000 budget. Internally, we called it “Instant Connections, Real Rewards.” Our objective was simple: get new sign-ups by tackling the big worries people have about financial tech, especially around data security. We aimed to build a real perception of reliability, not just rack up impressions.
Our strategy had to address the main barriers people have with fintech. A 2025 Statista report gave us our playbook, showing that 42% of non-users cited security fears as their top blocker, with another 35% simply not seeing the value. Our messaging needed to solve for both. We decided to go heavy on Snapchat Ads and Instagram Ads, since their young adult demographics were our key target and the platforms are perfect for the visual, community-based stories we wanted to tell.
Our creative was built on two pillars: authentic user-generated content (UGC) and dead-simple demonstrations of the app’s benefits. For the UGC, we worked with micro-influencers and existing Cash App fans to make short-form videos. They were simple, showing things like splitting a dinner bill, sending money to a friend, or getting a direct deposit. The key was genuine enthusiasm, not some polished, perfect ad shoot. We found that these raw, relatable stories just connected with people more deeply than the typical detached, high-production spots.
At the same time, we put out a series of animated explainer videos and static images that zeroed in on specific features: instant transfers, Cash Card perks, and investment options. A secure lock icon became a recurring visual, which subtly reinforced the security message without us having to scream about it. We also ran interactive poll ads on Instagram Stories, asking simple questions like, “Ever needed to send money instantly?” to pull users into a conversation before we offered them the solution.
Our targeting was anything but broad. We built lookalike audiences from our most engaged users and segmented them by age, U.S. urban and suburban areas, and interests related to personal finance and online shopping. On top of the lookalikes, we ran interest-based ad targeting for people following financial news outlets or personal finance blogs. One of the most effective tactics was geofencing around college campuses and popular shopping districts, which drove a surprising number of initial sign-ups.
The campaign launched big, hitting 35 million unique users across both platforms with an initial cost per install (CPI) hovering around $3.20. The early A/B tests, however, showed a huge performance gap in our creative. Ads that featured celebrities got plenty of impressions but a disappointing click-through rate (CTR) of 1.8%. In direct comparison, the ads showing our authentic user testimonials pulled a CTR of 2.7%. This was a critical insight: when it comes to financial services, authenticity builds more trust than star power.
So what didn’t work? Our first ads for the investment features were packed with technical financial jargon, and engagement completely fell off a cliff. We had to iterate fast, rewriting the copy to be about accessibility and ease of use (“Invest with as little as $1,” “Grow your money simply”). That small language change resulted in a 15% increase in conversions for investment-related sign-ups. We also found that our direct response ads with a clear “Download Now” CTA were far more efficient at driving actual registrations than the brand awareness ads were.
We were constantly optimizing for all six weeks. We did daily checks on our key metrics, CPI, CTR, and conversion rates, and if an ad set was underperforming, we paused it within 48 hours and moved its budget to a winner. For instance, after we saw how much better UGC was performing, we immediately shifted 40% of our creative budget to make more of those authentic videos. We also refined targeting weekly, cutting audiences that gave us high impressions but had no intent to convert. This kind of hands-on management was everything. We couldn’t just set it and forget it in social advertising.
By the end of the campaign, we had generated 2.5 million new user registrations that we could attribute directly to social ad exposure, hitting an average cost per lead (CPL) of $0.30 for those initial sign-ups. The overall return on ad spend (ROAS) was 2.5x, driven almost entirely by transaction fees from these new users within their first three months. We also saw a measurable increase in positive brand mentions on social media, which confirmed our trust-building strategy was working.
The “Instant Connections, Real Rewards” campaign proved that for fintech, you win by combining authentic user stories with clear benefit messaging and precise targeting. That’s how you drive acquisition and build the trust needed to make it stick.
