About Knix
Founded 2013 · CA
Joanna Griffiths founded Knix to solve the postpartum + period-leakage problem that mainstream underwear had ignored for decades. The brand built genuine category leadership in leakproof underwear before competitors (Thinx, Saalt, Modibodi) arrived. Acquired by Essity (the Swedish hygiene + health conglomerate) for $400M in 2022.

Notable for the theme detector
Knix's tech reflects the regulated-product + product-education needs of category-creator brands — heavy content + size-guide UX. Post-Essity-acquisition stack is interesting as a study in how DTC tech survives big-CPG ownership.

What this theme + customisation reveals
Knix's storefront declares "May Colours - (US|2026.05.27) Release\/4.12.0" via window.Shopify.theme JSON but the underlying CSS signatures don't match a commercial theme we track. That pattern is consistent with either (a) a fully-custom in-house theme that the team named after a project codename, or (b) a heavily-forked commercial theme where the original class prefixes have been stripped during customisation. Either way, the build effort here is meaningful.
75 inline scripts on the homepage suggests app-embed bloat — common in stacks that grew app-by-app over years.
Cross-check with the App Stack Detector to see how the apps installed interact with the theme — heavily-customised themes typically run thinner app stacks because custom code replaces app functionality.
