CASE STUDY: Rbia Shades is winning with POWR apps
A few months after Rbia Shades launched at local fairs and craft shows, they were looking for a way to sell online.
They wanted to visually appeal to site visitors and demonstrate the quality of their product and lightweight, ergonomic designs.
Their web host did not provide an adequate solution for this, and after some research, decided to give POWR a try.
Rbia started to see success with POWR Popup almost immediately, adding over 600 new contacts in the first 90 days.
They then realized that there was a complete suite of other solutions they could use to improve their online experience for site visitors.
Soon, Rbia embedded an Instagram Feed app on their website and noticed site visitors who interacted with the app doubled the time spent on their page while growing their followers to over 11k on Insta at the same time.

Every POWR app works on any platform.
