70 000 organizations and three million users today have the paid version of Slack, and a total of eight million who use the collaborative tool active every day, reports Reuters.
Slack was also stated that 500 000 organisations in total using their services.
There are considerably more than in september last year when there were 50,000 paying organizations, two million paying users and six million daily active users.
Despite the increase, the pace has come to a standstill, and the annual growth rate is now 45 per cent compared with 83 per cent between may 2016 and may 2017.
But it doesn't surprise analyst Alan Lepofsky of Constellation Research, who think that Slacks growth is very positive.
"I don't expect that the Slack will have the same exponential growth that initially now when the market is much more competitive," he says to Reuters.
