I work at Shopify, and last year we launched Polaris, our product design system. Polaris was a major step forward. Before it existed, we looked like a company that had 300 UXers working on a single product. But Shopify wasn’t internally consistent. And it definitely wasn’t externally consistent. Everything we’ve launched since June 6th, 2017 uses Polaris. Our teams are all bought in. PM and Engine
