Executive Summary

Slack is a subsidiary of Salesforce (NYSE: CRM), acquired in July 2021. Because Salesforce does not break out Slack-specific daily or monthly active-user metrics in its current earnings releases, Salesforce does not publish a current stand-alone Slack user metric in the cited earnings release. This article reports only what Salesforce’s FY2026 Q4 earnings press release discloses about the segment that includes Slack, and is explicit about what is not broken out.

Quick Overview

  • Salesforce acquired Slack in July 2021; Slack is now reported within Salesforce’s subscription and support revenue by service offering (source: Salesforce Q4 FY2026 earnings press release).
  • Salesforce FY2026 total revenue was $41.5 billion, up 10% YoY; RPO exceeded $72 billion, up 14%; current RPO was $35.1 billion, up 16% (source: same).
  • Salesforce Q4 FY2026 revenue was $11.2 billion, up 12% year-over-year (source: same).
  • The “Agentforce 360 Platform, Slack and Other” service offering generated $8,882 million in subscription and support revenue for FY2026 (source: same).
  • Salesforce reported 2.4 billion Agentic Work Units delivered to date across Agentforce and Slack, growing 57% quarter-over-quarter (source: same).
  • Salesforce does not break out stand-alone Slack user metrics or standalone Slack revenue in its current earnings releases.

How Salesforce Reports Slack

In its Q4 FY2026 earnings press release, Salesforce reports subscription and support revenue by service offering (source: Salesforce Q4 FY2026 press release). The offering labelled “Agentforce 360 Platform, Slack and Other” generated $2,655 million in Q4 FY2026 and $8,882 million for the full fiscal year ended January 31, 2026. This figure includes $388 million in subscription and support revenue from Informatica, which Salesforce acquired in November 2025. The same segment generated $2,655 million in Q4 FY2026 alone, up from $1,918 million in Q4 FY2025. Because Slack is bundled with other platform products, this is not a Slack-only revenue number.

What Salesforce Does Not Disclose About Slack

Salesforce’s current earnings releases do not break out Slack-specific daily active users, monthly active users or standalone revenue. The last widely cited standalone Slack user figure predates the July 2021 acquisition. Any stand-alone Slack user metric number presented without a primary Salesforce source should be treated as unverified. Salesforce does report that 2.4 billion Agentic Work Units have been delivered to date across Agentforce and Slack, growing 57% quarter-over-quarter (source: Salesforce Q4 FY2026 press release), but this is a combined metric, not a Slack-only usage figure. Salesforce also reported that Agentforce accounts in production increased nearly 50% quarter-over-quarter, and that more than 60% of Agentforce and Data 360 Q4 bookings came from existing customer expansion. These are platform-wide metrics and do not isolate Slack’s contribution.

Salesforce Company Context

Salesforce reported FY2026 total revenue of $41.5 billion (up 10% year-over-year), FY2026 operating cash flow of $15.0 billion (up 15%), and free cash flow of $14.4 billion (up 16%) (source: Salesforce Q4 FY2026 press release). Salesforce’s RPO exceeded $72 billion, up 14% year-over-year, and current RPO was $35.1 billion, up 16%. Agentforce and Data 360 ARR exceeded $2.9 billion, up over 200% year-over-year, including $800 million Agentforce ARR (up 169% year-over-year). Salesforce initiated FY2027 revenue guidance of $45.8 to $46.2 billion. These are company-wide figures; they do not isolate Slack’s contribution. Salesforce also reported FY2026 GAAP operating margin of 20.1% and non-GAAP operating margin of 34.1%, and returned $14.3 billion to shareholders including $12.7 billion in share repurchases and $1.6 billion in dividends. The company announced a new $50 billion share repurchase program authorization. Collectively, Salesforce industry businesses finished the year at $6.6 billion ARR, up nearly 20% year-over-year. Salesforce also reported that it has processed more than 19 trillion tokens to date, up 5x year-over-year, and closed over 29,000 Agentforce deals since launch.

Key Takeaways

  • Salesforce does not break out Slack-specific DAU or MAU; any current figure without a primary source is unverified.
  • “Agentforce 360 Platform, Slack and Other” FY2026 subscription and support revenue: $8,882M (bundled, not Slack-only) (source: Salesforce Q4 FY2026 press release).
  • Salesforce FY2026 total revenue: $41.5B, up 10% YoY; RPO $72.4B, up 14% (source: same).
  • 2.4 billion Agentic Work Units delivered across Agentforce and Slack, up 57% Q/Q; Agentforce ARR $800M, up 169% (source: same).
  • Salesforce FY2027 guidance: $45.8-$46.2B revenue (forward-looking, not actual) (source: same).

Reporting Boundary

Slack content needs a strict reporting boundary because Salesforce reports Slack inside broader service offerings. The combined service-offering figure can describe Salesforce disclosure structure, but it cannot be treated as Slack-only revenue. The same limitation applies to Agentforce and Slack work-unit references: they show a combined product context, not a standalone Slack usage metric. This article keeps those distinctions explicit so readers do not mistake a segment disclosure for a product-level statistic.

Methodology and Limitations

  • Salesforce does not break out Slack-specific stand-alone Slack user metric or standalone revenue; no such figure is reproduced.
  • “Agentforce 360 Platform, Slack and Other” is a bundled segment that includes other platform products and Informatica contribution; it is not a Slack-only number.
  • All Salesforce figures are from the official Q4 FY2026 earnings press release.
  • Forward-looking guidance is labelled as such; it is not presented as actual results.
