In 2014, the executives at a brand-new start-up called Andela made a decision whose consequences they would only understand much later. Andela’s model was to recruit and train promising African engineers, then place them at Western tech firms, which meant its employees and clients were scattered across time zones; it desperately needed a way for its distributed workforce to share information and make decisions easily and asynchronously, ideally without subjecting anyone to a deluge of emails. So the company started using Slack.
The maker of the chat software had recently become one of San Francisco’s trendiest new companies, based on a promise to make work communication more transparent and fluid. And at Andela, it did. As the company grew, Slack became its central nervous system, the place where business was conducted and where the company’s culture was formed.
