Brands moving with HI
What merchants say
“With HI Engine, one person now gets the same CRO results that used to take a team of five.”
From customer insight to a better shopping experience.
HI finds opportunities, builds improvements and tests their impact. You review and approve before anything goes live.
Customer understanding
Understand what holds shoppers back.
HI combines store data, shopping behavior and customer feedback to uncover friction in your shopping experience.
Illustrative example
AnalyzingCustomer insight
Shoppers may need clearer guidance on skin type.
- Store data
- Behavior & click maps
- Customer surveys
Every result informs the next improvement.
We believe conversion rate optimization should end with a change live on your store and its impact measured. Everything before that is backlog.
HI Engine next to the alternatives.
For teams with traffic and ideas but no one to ship the fixes.

KyleFounder at Swoveralls “For us, HI Engine did for CRO what Canva did for design.”
Libie Motchan DuggalFulton “HI Engine feels like magic; the opposite of AI slop. Building and launching CRO tests is so easy, I keep thinking, ‘Wait, it can actually do that?!’ At Fulton, it’s meaningfully impacted our conversion rate, engagement rate, and AOV.”
ElizabethCo-Founder, The Great Fantastic (ex-Brooklinen) “HI Engine takes so much of that work and does it for you. It’s an incredibly impressive tool.”
