Turn browsers back into buyers

Most shoppers who install your app never buy twice. Chumbaq follows up on carts, price drops and restocks across push, in-app, email and WhatsApp, and tells you which message made the sale.

Sample journey.

Where users slip away

  • 01

    Carts left behind

    People add to cart, get distracted, and never come back to pay.

  • 02

    One purchase, then silence

    The first order costs you an install. The second is where you make money.

  • 03

    Discounts you can't measure

    You send 20% off to everyone and can't tell who would have bought anyway.

Journeys you can run on day one

Each one is a journey you build once in Chumbaq. It runs for every new user who matches, and stops as soon as they reach the goal.

Know whether the discount was worth it

Hold back a control group and Chumbaq shows how many people bought because of the message, and how much revenue it added, so you stop paying discounts to people who'd have bought anyway.

E-commerce apps, answered

Can I track revenue, not just purchases?
Yes. Send the purchase event with its value and every campaign reports revenue alongside sales.
Does it work with Shopify?
Chumbaq works with your app through its SDKs and with your backend through the API. There's no Shopify plugin today.
