“The most significant impact that STS has had on our business has resulted in us feeling very relieved, but it comes from us knowing that they’re on our bench and allowing us to work in a very agile fashion and allowing our developers and designers to move quickly. This has made the work a lot more fun for everybody because everybody is focusing on what they love doing. It has also stripped away a lot of the fear of deploying software that isn’t great because whenever something doesn’t work, or when things aren’t perfectly logical, STS always catches it.”
