Problem: Shopify subscription brands run popup A/B tests through tools like Alia, Privy, and Klaviyo forms, but the reporting stops at opt-in rate. A brand can prove that Variant B captured 4 percent more emails, but has no idea whether those emails turned into subscribers who stuck around. Because subscription economics live and die on retention, an opt-in win can actually be a revenue loss if the higher-converting variant attracts lower-intent shoppers who churn in month one. Today that connection is invisible.
Named product: Popup A/B Test Analyzer connects to Alia-style popup data and maps each opt-in variant directly to 30-day LTV and repeat purchase rate. Instead of optimizing for the vanity metric of captured addresses, brands optimize the popup for the customers who actually stay.
Solution: The tool ingests popup variant assignment data and stitches it to Shopify order and subscription history. For every variant it reports opt-in rate, first-order conversion, 30-day LTV, and repeat purchase rate side by side. A brand can finally see that Variant A opts in fewer people but produces higher-retention subscribers.
MVP: A read-only integration with Shopify plus a popup data source (Alia or Klaviyo form exports), a cohort join on email or customer ID, and a single dashboard comparing variants across opt-in, 30-day LTV, and repeat rate. No campaign creation, no sending. Just attribution.
Revenue: Flat monthly SaaS per store, tiered by order volume. Given the niche and the analytics-only scope, expect a modest per-seat price with land-and-expand into agencies managing multiple brands.
GTM: Target agencies and DTC operators already teaching Klaviyo and popup setup on YouTube. Offer a free variant audit that reveals whether their current winning popup is actually their best retention popup.
Growth loops: Agency accounts pull in every client store. Shareable variant reports that flip the winner become social proof inside operator communities.
