“We spent a lot of time developing and configuring our checkout experience to handle merchants across several platforms on our gifting marketplace, and we still had thousands of lines of code to write to get it to work completely. With Violet, we were able to create a unified checkout experience for all our merchants in a couple weeks. And we’re now able to put our development resources into innovative experiences and features that weren’t previously possible.”
