The Slack Story

The Slack Story
Johnny Rodgers, Jamie Rosenfield, and Ali Rayl at one of many Slack company parties.

Building Slack is a project from Ali Rayl and Johnny Rodgers, two of the original employees of Slack. Between the two of us, we were involved in nearly everything the company did at every step of the journey. Plenty has been written about what Slack (the company) built and how Slack (the product) has changed the workplace forever. The stories that haven't been told are the ones about how we, along with so many others, built Slack.
