“Oracle had through acquisitions maybe a thousand or 2000 people using Slack, and in 15 months we took it to a 100,000 people wall to wall.”

The claim, plainly

Slack scaled its enterprise deployment at Oracle from 1,000 to 2,000 acquired users to 100,000 employees wall-to-wall within 15 months.

a quote alone can be ambiguous, so this restates it with the references and context of the conversation around it resolved. AI-written; the tape below the player is the source.

Assessment

While public reporting and SEC filings from Slack and Oracle confirm that Oracle expanded to more than 100,000 Slack users by early 2019 (having reached approximately 30,000 users around October 2017), the specific claim by then-CEO Stewart Butterfield regarding an initial baseline of 1,000 to 2,000 acquired users scaling to 100,000 employees within a precise 15-month window relies on internal deployment metrics. Neither company's public SEC filings, press releases, nor official case studies provide the granular timeline or pre-Enterprise Grid acquisition user counts required to definitively substantiate or refute the specific 1,000–2,000 starting figure and 15-month duration.

Slack Form S-1 (April 2019) and October 2017 partnership reporting documented Oracle using Slack (reporting 30,000 users in late 2017 and scaling past 100,000 users by early 2019).
No official corporate case studies, SEC filings, or press releases from Slack or Oracle document the specific initial baseline of 1,000–2,000 acquired users or the 15-month expansion timeframe.

Butterfield: Microsoft Teams competes primarily with Zoom rather than Slack

“Teams, which is the real alternative in some sense, although I think it's much more of a competitor to Zoom or other voice and video calling services than it is a Slack.”

Butterfield: Microsoft Teams is limited to 5,000 users and 200 channels

“It's limited to 5000 people per instance and critically only 200 channels. And if you want to add a 201st channel, you have to hard delete one of them without the whole history.”
