About This Dataset
The Companies Using Slack database covers 33,750 verified companies across North America that are active Slack customers — companies using Slack Free, Slack Pro, Slack Business+, or Slack Enterprise Grid as their primary team communication and collaboration platform.
Every record identifies the Slack decision-maker or workspace admin — IT Admin, Founder, VP of Engineering, Head of Operations, or CEO — with a confirmed work email, LinkedIn URL, Slack plan tier (Free, Pro, Business+, Enterprise Grid), primary use case (engineering, sales, cross-functional, customer support), company size, and full company profile.
Slack is the collaboration backbone of technology-first, remote-friendly, and engineering-driven organisations — making Slack's install base one of the most commercially valuable signals for vendors targeting the modern software-driven enterprise. Slack customers are sophisticated buyers of productivity tools, developer tools, and workflow automation.
Ideal for: Slack App Directory partners building bots and integrations, workflow automation tool vendors (Zapier, Make, Workato), asynchronous video and documentation tool companies, developer productivity platform vendors, and companies building Salesforce-adjacent tools (Slack is now part of Salesforce). Updated quarterly.
