Preview text: Ideas piled up, shipping lagged, and engineering time was tight. Then four months.
21% lift. $1.5M+. Four months.
Hi ,
Every line below is quoted from our L-Nutra case study, so you can check all of it.
Where they started:
"L-Nutra had momentum." But "experiment velocity wasn't where they knew it could be."
"Ideas piled up, shipping lagged, and engineering time was tight."
"The existing CRO agency they were working with wasn't keeping up."
What came out of it:
"21% conversion lift on winning variants"
"$1.5M+ projected incremental annualized profit in just four months"
"over 27x ROI"
All verbatim from the L-Nutra case study, coframe.com
"Very impressed by Coframe. They're more than another AI tool. They've replaced my entire CRO function."
Bryan Welker, SVP of Growth & Consumer, L-Nutra
We can run the same first pass on your site. It takes about a minute, and you get the variants built, not just a report.
