Global leader in CRM (customer relationship management) software, Salesforce, will acquire Slack Technologies, Inc., Microsoft Teamsβ most relevant rival in the collaboration space. As per the agreement, Slack shareholders will receive $26.79 in cash and 0.0776 in shares of Salesforce common stock for each Slack share, totaling $27.7 billion.
I reached out to Irwin Lazar, VP and Service Director, Nemertes Research, who told UC Today he sees the deal playing out in a few ways. He also said that the move will likely speed up Slackβs momentum.
βThough Slack has a loyal user-base, they have faced increasing headwinds in the enterprise market against Microsoft Teams, namely as Teams has improved over the past yearβ

Lazar said that Slack now has the proper resources to build out its team collaboration platform and to integrate Salesforce with other apps. On social media, the move has largely been touted as a good one, and Lazar echoes this sentiment, calling the move a βhuge winβ for the Salesforce customer base. βThey now have access to a best-in-class collaboration, integration, and workflow management platform with tight integration to Salesforce.β
Looking toward the future of the duo, Lazar said that Salesforce could decide to more aggressively go after Microsoft Teams, something he said we will watch play out in 2021. He believes that the big challenge for Slack will be reassuring its customer base that it will remain a stand-alone platform. The developer community, which he holds is perhaps Slackβs biggest user-base, will take the most convincing. βCompanies like Mattermost and Rocket.chat might try to capitalize on the move and displace Slack in those communities as a result.β
Marc Benioff, Chair and CEO, Salesforce, said in a statement: βTogether, Salesforce and Slack will shape the future of enterprise software and transform the way everyone works in the all-digital, work-from-anywhere world.β
Slackβs CEO and Co-Founder, Stewart Butterfield, noted:
βThe opportunity we see together is massive, especially as software plays a more and more critical role in the performance of every organizationβ
I also reached out to Zeus Kerravala, Founder and Principal Analyst, ZK Research, to get his take on things. He said there may be UCaaS implications stemming from the deal. He believes that most UCaaS vendors are unlikely to be impacted by the move, noting that the acquisition does not hold the same undertones for Microsoft. βThis is a shot across the bow for Microsoft, and it finally gives Salesforce an application they can use to take Microsoft on directly.β
Echoing Butterfieldβs previous claims that Microsoft padded its numbers because it included its Microsoft Teams collaboration app with Microsoft 365 user subscriptions, he said: βSlack is a good product, far better than Teams, but Microsoft never let Slack catch up to it because it offers a good enough product while bundling the offering into its Microsoft 365 licenses.β This, Butterfield has long maintained, gives the company an unfair advantage. I asked Kerravala what the most ideal outcome for the pair would be in his eyes, to which he responded:
βI would like to see Salesforce use this as a starting point to buy, build out a file-sharing company, or even a UCaaS vendorβ
