Slack’s strapline is ‘Be less busy’ and it aims to bring different types of communication, such as email, into one place.

In November 2015, at barely two years old, it received funding valuing it at an astonishing $3.8bn (£2.6bn) and its website suggests it is contributing to space exploration: NASA is a client, while its homepage features a robot exploring Mars.
