Salesforce has completed its long-awaited mega-slurp of Slack Technologies, Inc for an eye-watering $27.7bn. The intention to buy was made public back in December 2020, when the business run by Marc Benioff said: "Slack will be deeply integrated into every Salesforce Cloud." The CRM firm said Slack, which at the time had listed just 18 months before on the NYSE with a valuation of $16bn+, would also become the interface to Salesforce's CRM platform.
But in February 2021, the US Department of Justice wrote to Salesforce and Slack to investigate the merger further.
The app runs on a freemium model, with free tier users outnumbering those on the paid version. As of 31 January, 2021, it had 156,000 orgs coughing up to have three or more users on a paid subscription plan, up from 110,000 in 2020 and 88,000 in 2019 (rounded down to the nearest thousand). Over 1000 of those customers – including IBM, which The Reg understands has been using a fair amount of the chat app lately – paid over $100,000. In its latest annual report, the firm said that as well as attracting new users, the company had been hoping to "convert users of and organizations on our free version into paid customers".
Slack has said it has 12 million+ daily active users, and chomps through tens of billions of daily database queries. The firm has not recently provided data on the breakdown of free and paid users – although during its 2019 listing, it filed an S-1 with the SEC showing 600,000 orgs had accounts with more than three users, and 88,000 of those were paid customers (14.6 per cent of the total). In its last filing, for Q1 ended April 30, 2021 Slack noted "a $5.6m increase in third-party hosting costs for users on a Free subscription plan of Slack, primarily due to continuing growth in our user base, and a $0.7 million increase in facility- and IT-related overhead costs to support our headcount growth."
