CASE STUDY: Rbia Shades is winning with POWR apps

After Rbia launched its website, they were looking for a solution to add new contacts for outreach.


They found POWR while looking for a popup solution on their site and started to see immediate results.

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 full 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.
