Run on evidence, not instinct.Introducing Mend — the first AI decision engine for attributionThe AI decision engine

Forms & Incentives Ask who sent them. Reward the answer.

Build a short form once, put it in checkout, on your storefront, on your site or behind a link, and pay every answer with a discount code or a credit. The buyer names the partner. That is the attribution.

The form builder, on Halcyon Skin’s post-purchase form, a sample store. Switch the flow, pick a question, or answer the preview and press Next to step through it as a buyer.

One form. Asked wherever the buyer already is.

The questions are written once. Each place draws them with its own renderer, at the width it is really answered at, so a checkout answer and a link answer land in the same responses.

When it opens

On your site or storefront, a pop-up waits for the moment you choose. Stack rules and it opens once every one of them holds.

  • Page URLOnly on pages matching any of these patterns
  • Time on pageAfter the visitor has been on the page this long
  • Scroll depthOnce the visitor has scrolled this far down
  • Exit intentWhen the cursor leaves toward the top of the window

How a form is built, previewed and paid for

  1. Question types

    • Partner picker

      One partner from the form's roster, plus Other.

    • Channel picker

      One channel from the form's channel list.

    • Dropdown

      Pick one of the listed options.

    • Multi-select

      Pick several, with an optional min and max.

    • Short text

      A line of text, optional length.

    • Long text

      A few sentences, optional length.

    • Email

      A valid address, where the reward goes.

    • Number

      A number, with an optional range.

    • Heading

      Display only, no answer collected.

    Written for you at publish, asked only when they apply

    • Channel detailWhich kind of channel it was, asked only of those who picked one.
    • Post linkThe link to the post they remember, asked after a partner is named.

    Questions that know your partners.

    Nine question types, two of them pickers drawn from your own roster and channels. Name a partner and the follow-ups that only make sense after one appear on their own, gated on the answer.

    3 questions, under 30 seconds — a fast flow for a smaller discount. 8–12 questions, up to 90 seconds — deeper answers for a bigger discount.

    And by how far they got

    EnhancedNewCompletedHALCYON7K2Q · 20% off

    Pay for the answer, not the visit.

    Offer a quick flow for a smaller reward and an enhanced one for a bigger one, set a different reward for returning customers, and decide what a finished, a half-finished and a skipped form each earn.

Reward in whatever your buyers spend.

A retailer hands back a percentage. A software company hands back credit. The incentive is configuration on the same form, settled by the tool that already holds the money.

  • Rewards go to an addressA form can only carry a reward once it asks where to send it, and that address is what a per-buyer limit counts, so you decide how often one buyer can claim.
  • Returning buyers, recognisedWith a Shopify store connected, a buyer who has ordered before gets their own questions and their own reward, decided before the first screen.

The answer is the attribution.

A buyer naming the partner who sent them is first-party evidence, given at the moment of purchase by the one person who knows. Mend reads every answer beside the order’s codes and links, and says what it proves.
