Cartwheel Commerce
A headless storefront and merchandising platform delivering personalized shopping at scale during peak Black Friday traffic.
Cartwheel's monolithic storefront buckled every Black Friday. They needed a headless platform fast enough to convert and resilient enough to survive peak.
The challenge
Pages loaded in seconds, personalization was non-existent, and the yearly traffic spike routinely caused outages that cost real revenue.
Our approach
- 1
Migrated to a headless Next.js storefront with edge rendering and caching.
- 2
Built a real-time personalization and merchandising engine.
- 3
Load-tested to 4× historical peak before launch.
- 4
Instrumented full analytics to tie UX changes to revenue.
The results
Our Black Friday used to be a fire drill. This year we handled 4× the traffic on the new stack — zero downtime, conversion up 37%.
