Giving Wair a try on our site. So far customers seem to be utilizing it and we see some improvement in conversions. The team was really helpful in getting us up and running and quick to respond to any issues or concerns.

We’ve had a great experience working with the Wair team. Troy, Greg, and Chris are all super helpful and quick to respond. They handle sizing questions and make adjustments quickly. The app has been great for both conversion and our average order value. We highly recommend!

The WAIR team made the onboarding process seamless from start to finish. The setup was straightforward and turnkey, requiring little effort on our end. What stood out most was how flexible and cooperative the team was in working with us to test and validate everything before going live. Their support has been excellent, and the analytics they provide go far beyond what we’ve seen from other providers offering valuable insights that help us continuously improve our customer experience.
