Zapfast
73% sales lift in the first month
A brand-locked content engine producing product copy, campaign variants and localisations at catalogue scale.
The challenge
Zapfast added roughly two hundred SKUs a month and each one needed copy in four languages. Freelance output was inconsistent enough that the brand voice drifted noticeably between categories.
What we built
We encoded the brand guide as a set of machine-checkable constraints — tone, banned claims, reading level, structure — and ran generation through them. Anything failing a constraint regenerates automatically rather than landing in a reviewer's queue.
The outcome
Catalogue copy that used to lag launches by weeks now ships with them, and the voice is measurably more consistent than it was under human freelancers.
“Our launches stopped waiting on copy. It just arrives with the product now.”
