Why Loop uses Revend
In 2022, the Loop team installed Revend to help keep a close eye on the operational metrics of their Shopify-powered stores across the world. With years of strong growth on the horizon, Loop trusts Revend’s 24/7 monitoring to make sure no potential webshop issue is left undetected.
Revend monitors operational KPI metrics in real-time (e.g. product views, clicks, add to carts, checkouts, purchases), and uses different AI models to determine when a deviation of these metrics indicates potential trouble before sending a notification via Slack, Teams, or email.
The result? Loop’s Shopify team has a lot more peace of mind, and is able to solve issues faster. If something is going wrong that might affect their customers, Revend is the first to tell them.
A use case
On the 14th of April of 2023, at 11.30 AM, the team at Loop Earplugs received the following Revend message on Slack:

In an instant, the Loop Earplugs team learns the following things:
- In the last hour, add to carts for their Australian webshop had been down 56% compared to the expected average, and 11% compared to the expected minimum.
- This is costing them an estimated amount per minute (blurred at Loop Earplugs’ request).
- Add to carts had been below the expected minimum for over 15 minutes, and it is still going on.
- Only this part of the funnel seems affected so far, so the damage is still contained.
- They can see every measuring point of the Revend model, to understand why a message was sent. (blurred at Loop Earplugs’ request).
- As with every Revend message, they can indicate whether this was an actual issue or a false positive after the fact to train their model.
Alerted by Revend, the Loop team investigates the add to cart section of the webshop in question and discovers that, indeed, something is going wrong.

After doing some digging, they found that the crash of a third party fulfilment app linked to their store was responsible for the issue.
Within 20 minutes after receiving the Revend notification, Loop’s team was able to spot, identify, and fix the issue.
The impact of real-time monitoring
Because they were promptly notified and given context in real-time, the day was saved a lot faster than in the pre-Revend days. The Loop team estimated that at least a few hours worth of revenue was saved due to Revend’s timely notification.
On top of that they have more peace of mind knowing Revend automatically monitors every step of their customer journey around the clock.
The cherry on top? Loop’s customers no longer risk getting frustrated with an issue when buying their favourite earplugs. Everybody wins 😊
