The brainchild of Flickr co-founder Stewart Butterfield, Slack has risen to become the web's most popular corporate chat client. In a crowded space and seemingly saturated market, Slack has become a cult hit. It's beloved for its gorgeous, bubbly interface and tons of delightful little interactions throughout the app.
We were there from the start. Stewart and his team came to us when Slack was a rough, unstyled prototype, and we worked with them to design the app from the ground up. The brand, the web app, the mobile app, and even the marketing site—the works. We couldn't be more chuffed about how it turned out, and thousands of Slack customers seem to agree.
