About Slack
Slack is a team messaging and collaboration platform founded in 2013 by Stewart Butterfield. Salesforce acquired Slack in 2021 for $27.7 billion. As of April 2026, Slack serves 750,000+ organizations with 65+ million daily active users worldwide.
Workflow Builder (rebuilt in 2023) enables no-code automation directly within Slack. Workflows are assembled from triggers (new channel message, emoji reaction, webhook, schedule, shortcut button), steps (send message, collect information via forms, create a Canvas document, call an external API, update a channel topic), and connectors to external tools (Google Sheets, Salesforce, Jira, Asana, and others via Slack's connector framework). Workflows can run in the background or interact with users through forms and messages. The free plan includes 90 days of message history and basic Workflow Builder access. Pro plan ($7.25/user/month) provides full message history, unlimited integrations, and advanced Workflow Builder features. Business+ plan ($12.50/user/month) adds SAML SSO, data exports, and compliance features. Enterprise Grid is available at custom pricing for large organizations.
Slack Connect enables cross-company collaboration in shared channels. Slack AI (launched 2024) adds AI-powered search across messages and files, conversation summaries, and channel recaps. The Slack App Directory includes 2,600+ integrations with tools like Google Workspace, Microsoft 365, Zoom, Salesforce, Jira, GitHub, Asana, Trello, HubSpot, and Notion.
