SRS Pay: scaling paid acquisition for a payment platform
Unified attribution and Cortex-powered ad optimization drove 4.2× ROAS while cutting cost per acquisition by 38%.
Challenge
Fragmented channels, rising CPA
SRS Pay ran performance campaigns across Google, Meta, and affiliate networks, but conversion data lived in separate dashboards.
Without a single view of funnel events — from ad click to first transaction — the team over-invested in low-intent placements.
Cost per acquisition climbed for three consecutive quarters while return on ad spend plateaued below target.
Solution
End-to-end measurement with Cortex
Cortex connected ad platforms, web analytics, and payment events into one attribution model with real-time cohort reporting.
Ads Agent restructured campaigns around high-LTV segments, pausing underperforming geo and device combinations automatically.
Landing pages were rebuilt with A/B tests tracked in Cortex Monitor, aligning messaging with trust signals fintech users expect.
Results
Efficient scale without guesswork
Within two quarters, SRS Pay achieved 4.2× blended ROAS and reduced CPA by 38% — while increasing verified merchant sign-ups by 62%.
