- The legal entity name transitioned from 'Slack Technologies, Inc.' (pre-acquisition public company) to 'Slack Technologies, LLC' (post-acquisition subsidiary); the LLC form is confirmed by multiple secondary sources but not independently verified via a state registry filing in this investigation.
- No private equity involvement was found at any point in Slack's post-2021 ownership chain; pre-acquisition VC investors (Accel, Andreessen Horowitz, SoftBank, Thrive Capital) were not PE owners and their stakes were fully extinguished by the Salesforce acquisition.
- Salesforce shareholder composition (institutional investors, index funds, etc.) was not investigated; large institutional holders such as Vanguard or BlackRock hold Salesforce stock but this does not constitute PE ownership of Slack.
