One order is a sale. Two make a regular.

We learn when each customer is about to run out and send one note in your voice, just in time. The second order comes at full price.

You approve until you trust it. Then it runs itself.

Example

In short

Whisperrfor e-commerce is an autonomous retention engine for online stores and shopping apps. It learns when each customer is likely to buy again, sends one email or push at that moment, and counts the extra orders against a holdout group.

Everyone runs on a clock.

A bag, a bottle, a box: each one runs out on its own schedule. We learn yours, customer by customer, and speak up a few days early.

  1. Day 1First bagWhole beans, 250 g. Bags this size last about a month.
  2. Day 22Running lowAbout a week of coffee left.
  3. Day 26, 08:05One emailOver breakfast, when she reads her mail.
  4. Day 26, 08:19Second orderFull price. The new bag lands before the last cup.

Example: one customer and one bag of coffee, over one month.

Coupons teach people to wait.

Mail the whole list a code and they hold out for the next one. Send one person the right note and the price can stay.

Example

A few moments make a regular.

  • Running store

    Your trail runners are still in your size

    Size 42 is in stock. If they don't fit, returns are free.

    Cart left behind

    A nudge the same evening beats a discount a week later.

  • Plant shop

    Your monstera is a day behind

    The courier now says Thursday. We'll write the moment it's out for delivery.

    Parcel running late

    A late parcel with no word is how a first order becomes the last.

  • Pet food store

    Too much food in the cupboard?

    Move Biscuit's deliveries to every six weeks. Same food, less piling up.

    About to cancel

    Most cancels are about timing. Offer a slower schedule first.

  • Skincare brand

    The serum you loved is back

    It sold out in June. It ships again tomorrow.

    Gone for months

    Lead with what's new, not with a discount.

  • Nothing sent

    Ordered two days ago

    Her bag is on its way. Anything else now is noise.
