5-Store Cosmetic Chain

+11.9% CTR·+7.9% conversion rate
2-week pilot·Shopify Hydrogen · DatoCMS

The Problem

Same "Summer Glow" banner across beach, college, suburban, mall, and outlet stores.

What Changed

Beach store showed "Salt-Resistant SPF" when UV > 8 (CTR +14%). College store showed "Dorm-Friendly Minis" during move-in week (CTR +18%).

“"We knew our beach store converted better on SPF and our college store on minis. We just couldn't automate it. Now it's automatic. And Legal was thrilled — no cookies, no consent banner."”

— Marketing Lead, 5-Store Cosmetic Chain

Regional Grocery (350 Stores)

+8.0% CTR·+3.2% AOV · -100% manager banner time
30 days · Production·DatoCMS · Next.js · Vercel Edge

The Problem

350 stores across 4 states. Weather drives purchasing, but every store showed the same homepage banner. Store managers spent 3 hrs/week manually overriding.

What Changed

Mem0 enabled: remembers what converted without tracking who. Chicago visitor gets "Hearty Winter Meals" next session — no login, no cookie.

“"Weather-based banners alone paid for Busyfolder in month 1. Soup on rainy days, grill supplies on sunny weekends — automatic. Store managers got 3 hours of their week back."”

— VP Marketing, Regional Grocery

Franchise Convenience (500 Locations)

+12.0% CTR·+55% on event-day banners · +138% franchisee compliance
60 days · Production·Contentful · Shopify Hydrogen

The Problem

500 franchise stores. Corporate wanted brand consistency. Franchisees wanted local relevance. Nobody won — 60% of franchisees never updated banners.

What Changed

Event-driven banners auto-activate 24hrs before game day/concert and deactivate after. UT Austin stores show "Longhorn Game Day Specials" (CTR +62%). Madison Square Garden area shows "Pre-Show Snacks" (CTR +48%).

“"We solved the franchise branding problem we've had for 10 years. Corporate picks the menu. Franchisees add the specials. Busyfolder picks the plate. Legal didn't blink — no cookies means no franchise data-sharing headaches."”

— Franchise Operations Director, Franchise Convenience
