From one changeto the first conversation.

A real account, start to finish: what Shoplist showed when Baumgarten Kinderwagen removed Recharge, and what you do next.

  1. Catch the change.

    Sonar stopped seeing Recharge on Baumgarten Kinderwagen on Oct 15, 5 months after it first appeared. If you sell a subscriptions app, that is the week to call.

  2. See what’s left.

    9 apps still run there, CookieYes GDPR Cookie Banner and Elfsight Instagram Gallery among them. No helpdesk, loyalty, subscriptions and upsell app is detected. That’s the shape of the opening, and of your pitch.

  3. Save it. Hear when it moves.

    Add the brand to a list with the reason attached, follow it, and get a Slack or email alert the next time its stack changes. Export the list when you’re ready to reach out.

If Shoplist shows an app on a store,it’s there.
