โSet it up on a Tuesday afternoon, got our first accept before dinner. Didn't expect it to work that fast honestly. Accept rate is sitting at 14% after the first week.โ
Jessica M.
Clean beauty brand
โSwitched from AfterSell and it's not even close. Our offers actually look like our brand now instead of the same template every other store has. The editor is way more flexible than anything else I've tried.โ
Daniel R.
Premium supplement brand
โAdded quantity breaks to our main upsell and went from 1 unit per accept to 2.3 on average. People just pick the middle tier every time. Doubled our upsell revenue without changing the product.โ
Sarah K.
Pet supplies store
โWe A/B tested an urgency template vs a trust-heavy one and the trust template won by 31%. Without the testing feature we'd still be guessing. Kairo paid for itself in the first 3 days.โ
Marcus T.
Fitness apparel brand
โWas skeptical honestly - figured customers would be annoyed. Most do decline, but the ones who accept add $18-25 to their order. Adds up to over a thousand extra a month we weren't making before.โ
Amy L.
Handmade jewelry shop
โSupport answered my setup question in 12 minutes on a Saturday. The thank you page customization is a bonus I didn't expect - we added a survey and a discount code for next purchase. Repeat order rate is up 8% since.โ
