“Paid Customer growth, which is the single most important driver of the business over the long term, accelerated in Q2, up 30% year-over-year. One of the drivers of this acceleration was Slack Connect, which offers seamless, secure intercompany collaboration that we believe is light years ahead of email. We ended the quarter with more than 380,000 connected endpoints, up more than 200% year-over-year, and now more than 52,000 Paid Customers use Connect, up 160% year-over-year.”
