Best for

- Customer-facing teams that work with clients and vendors through Slack Connect
- IT and engineering teams that want to embed AI assistants and agents where people already work
Ideal size: 50-5,000+ employees people · Scale-up or enterprise with a dedicated IT or workspace admin
Not for
- Teams that only need lightweight free group chat with no admin overhead

- Businesses with mostly frontline, shared-device workforces and no device management

Bottom line
Slack is Salesforce's AI work platform: channels, huddles, canvases, lists and Workflow Builder, now centered on Slackbot, a personal AI agent, plus enterprise search and Slack CRM. More than 2,600 apps and MCP servers connect the rest of the stack, while enterprise controls cover SSO, SCIM, DLP, legal holds, data residency and audit logs. Plans start free, with Pro at $7.25 per user per month annually and Business+ at $15, so deployment is low-friction but the per-seat cost compounds at scale.
Frequently asked questions
What does Slack actually cost for a mid-size company?
List pricing is per active user per month: Free ($0), Pro at $7.25 when billed annually, Business+ at $15 annually, and Enterprise+ at $45 annually via sales. Annual billing is cheaper than monthly. Only members who take an action in a 28-day window are billed, so inactive accounts are normally credited. A 100-person Business+ deployment works out at roughly $18,000 per year before any add-ons.
How fast can we be live, and is there an implementation fee?
Slack is self-serve: a team can create a workspace on the Free plan and start working the same day, so time to first value is short and there is no mandatory implementation fee. Paid plans are also purchased online. Enterprise+ is quoted through sales and large rollouts typically involve identity-provider setup, retention policy design and app governance, which is where most of the real effort sits.
Is our data used to train AI models?
No. Slack states that customer data is not used to train large language models and is not shared with LLM providers, and that the models run inside Slack's own AWS virtual private cloud. AI only works with content a user already has access to. Admins can also restrict which channels, canvases and lists AI features can read on Enterprise+.
What compliance certifications does Slack hold?
The security page lists SOC 2 Type II and SOC 3, ISO/IEC 27001, 27017, 27018, 27701 and 42001, HIPAA configurability for e-PHI, FedRAMP Moderate authorization, FINRA 17a-4 configurability, GDPR commitments and data residency. GovSlack adds FedRAMP JAB High authorization. Certificates and reports are downloadable from the security page.
Which of our existing systems will Slack connect to?
Slack advertises more than 2,600 apps, with first-party Salesforce context in channels, Google Workspace and Microsoft 365 integrations, AWS Chatbot, HubSpot, ServiceNow, Jira, GitHub and others, plus Workflow Builder connectors and a public API. A native Slack MCP server lets AI assistants such as Claude and Cursor read Slack data and take actions.
What support is included on each plan?
24/7 support is listed for Pro, Business+ and Enterprise+, with a 4-hour first response time on Business+ and Enterprise+. The Free plan has no support commitment; self-serve Help Center documentation is available to everyone. Slack also runs a platform community for developers building apps and agents.
