Slack remains one of the most widely adopted workplace communication and collaboration platforms, serving 200,000+ paid customers and organizations across more than 150 countries. Its reach extends deep into the enterprise market, with 77 of the Fortune 100 using Slack to connect employees, coordinate projects and manage business communication. However, Slack now plays a much broader role than workplace messaging. Companies increasingly use the platform to connect business applications, automate repetitive processes, search organizational knowledge and bring AI agents directly into everyday workflows. Sales teams can work with CRM information inside conversations, while IT, customer service and operations teams can use workflows and integrations to move tasks forward without constantly switching applications.
With billions of messages and actions flowing through the platform each week, Slack has become an important layer of the modern digital workplace. These Slack statistics examine its users, revenue ecosystem, market share, engagement, enterprise adoption, integrations and competitive position.
Editor’s Choice
- Slack serves 200,000+ paying organizations, making paid-customer scale one of its clearest publicly disclosed adoption metrics in 2026.

- The Agentforce 360 Platform, Slack and Other reporting category produced $8.882 billion in subscription and support revenue in fiscal 2026, compared with $7.247 billion in fiscal 2025. Importantly, this figure includes products other than Slack and should not be treated as Slack-only revenue.
- That reporting category increased by approximately 22.6% year over year on a reported-dollar basis in fiscal 2026, although $388 million of the fiscal 2026 total came from Informatica after its November 2025 acquisition.
- In Q1 fiscal 2027, the former Agentforce 360 Platform, Slack and Other category recorded 43% constant-currency growth, compared with 14% in Q1 fiscal 2026.
- Slack Model Context Protocol passed 1 million active users in six weeks, one of the clearest new Slack adoption metrics reported in 2026.
- By July 2026, Slack held a 1.06% popularity share and 1.39% spend share in one dataset tracking 769 collaboration and productivity products.
Recent Developments
- In January 2026, Slack introduced a rebuilt Slackbot positioned as a personal work agent that can draw on workspace and connected information to help users find information and complete tasks.
- By March 2026, Slackbot could use Salesforce data alongside conversations, files, connected apps and other authorized information to answer natural-language questions.
- Slack introduced a Salesforce Activity Timeline experience in 2026 that brings emails, calls, meetings and tasks into the Slack view of a customer record.
- The April 2026 feature cycle added or announced Slackbot actions for creating and updating Salesforce records, extending the agent from information retrieval to work execution.
- Slack also expanded Slackbot through Model Context Protocol, allowing the agent to take actions across compatible third-party applications. The MCP capability surpassed 1 million active users within six weeks.
- Slack’s 2026 roadmap added document, spreadsheet and presentation generation through Slackbot, reducing the need to move between separate productivity interfaces for some tasks.
- Voice commands and web search joined the announced Slackbot capabilities in 2026, broadening the ways employees can interact with the agent.

Slack Revenue Statistics
- Agentforce 360 Platform, Slack and Other generated $8.882 billion in subscription and support revenue in fiscal 2026.
- The same category generated $7.247 billion in fiscal 2025, creating a year-over-year reported increase of about $1.635 billion.
- On a reported basis, category revenue therefore grew approximately 22.6% between fiscal 2025 and fiscal 2026.
- However, fiscal 2026 category revenue included $388 million from Informatica, so the reported growth rate overstates the organic comparison for the preexisting portfolio.
- Excluding that $388 million contribution for a rough like-for-like calculation, fiscal 2026 category revenue would have been approximately $8.494 billion, about 17.2% above fiscal 2025. This is a derived figure, not a separately reported Slack result.
- In the quarter ended Jan. 31, 2026, the category generated $2.655 billion, compared with $1.918 billion in the corresponding quarter a year earlier.
- For the first nine months of fiscal 2026, Agentforce 360 Platform, Slack and Other produced $6.227 billion, up from $5.329 billion during the comparable fiscal 2025 period.
- The reporting category recorded 37% constant-currency growth in Q4 fiscal 2026, up sharply from 19% in Q3 fiscal 2026.
- In Q1 fiscal 2027, the former reporting structure showed 43% constant-currency growth for Agentforce 360 Platform, Slack and Other. Because the category includes several products, that percentage should not be interpreted as Slack’s standalone revenue growth.
