What this list shows
anvendor scans identify evidence that companies use Slack. Coverage includes SaaS used internally without a detectable trace on a company's public website. The examples include annual spend estimates where available. Reveal a company in the app to see its available headcount and estimated adoption. Use the findings to prioritize prospecting; they do not establish buying intent or willingness to switch.
These examples can include older scan results. Results less than 30 days old are fresh and may be reused; paid access still applies where required. Reveal does not always start another scan. Choose Refresh in the app to start a new live scan now at the displayed credit price.
This page shows customer examples, not an exhaustive list. A company missing from this page may still use Slack. Results indicate a subscription relationship; they are not invoices or a guarantee of current usage.
