Our friends at Wix make it possible for everyone to build beautiful, professional websites. They've had amazing successes, skyrocketing from 5 million to 50 million users in less than 3 years. It just so happens they're also huge Scala fans! In our interview with Shai Yallin and Tomer Gabel, they discuss how Scala was the perfect language for future-proofing Wix against massive scale challenges. They've rewritten much of the codebase from Java into Scala, and have a mandate that all new products be written in Scala.
