When Microsoft announced it had more than 20 million daily active users for Microsoft Teams back in November of last year, Slack’s stock fell as much as 11%. The competition between Slack and Microsoft Teams has heated up quite a lot in recent times and looks like it’s about to get more heated.
Business Insider reports that IBM just became Slack’s biggest customer, and will be moving all its 350,000 customers to the service.
The news has helped Slack’s stock surge as much as 21% today. A big company like IBM committing to Slack is obviously a very good look for the company, which has lately been facing a lot of pressure from Microsoft Teams.
IBM has apparently actually been using Slack since 2014, but it is now officially adopting Slack as the main communication tool internally as part of a larger effort to modernize the company itself. IBM’s Konrad Lagarde, who is in charge of the transition and is the director of productivity and developer tooling, said that IBM is adopting Slack mainly because its employees liked using the service. Slack CEO Stewart Butterfield said that working with IBM helped the company refine its product for the large customer.
This is obviously a very good boost for Slack, but it still will not be enough to compete with Microsoft Teams. Slack will need to continue getting more large customers like IBM in order to keep this up, so it will be interesting to see how well the company does on that front.
