CASE STUDY: POWR put Rbia Shades on the success track
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.
In just a few short months of installing a POWR Popup app, Rbia earned over 600 new contacts – a 250% growth.
Next, they used a Social Feed app and quickly noticed a leap in new followers on Instagram and 200% more engagement on their site.
Last came the Media Slider. A beautiful way to show off their products and accessories to every site visitor the moment they land on their site.

Every POWR app works on any platform.
