Slack’s customer acquisition

• Slack had 130,000 paying customers by the end of July, up from 110,000 in January, meaning that the company added almost as many customers over the past six months as it did in the twelve months prior.

• Slack defines paid customers as organizations with at least three users on a paid subscription plan, and it registered particularly strong growth among its largest customers.

• While customer growth amounted to 30% year-over-year overall, the number of organizations spending over $1 million annually was up 78% over last year’s July quarter.

• Customers with more than $100,000 in annual revenue increased by 37%, also growing faster than the overall customer base.
