Slack

What Slack does

Slack is a cloud-based team collaboration platform serving approximately 1 million businesses worldwide, operating as a wholly-owned subsidiary of Salesforce since the $27.7 billion acquisition in 2021. The platform provides organized communication through channels, direct messaging, audio/video huddles with AI transcription, recorded clips, collaborative canvases, project lists, and a no-code Workflow Builder. Slack has repositioned itself as an AI-powered operating system for work, with Slackbot serving as the central conversational agent powered primarily by Anthropic's Claude and supplemented by OpenAI's ChatGPT integration. The platform's proprietary Model Context Protocol (MCP) server and Real-Time Search API enable third-party AI agents from OpenAI, Anthropic, Google, Perplexity, Writer, Dropbox, and Notion to securely access conversational data, while Slackbot's MCP client orchestrates natural language workflows across 20+ enterprise applications including Atlassian, Box, Canva, DocuSign, Miro, and Zoom.

The business operates a tiered per-seat subscription model: Free (basic features, 90-day message history, 10-app limit), Pro at $7.25/user/month, Business+ at $15/user/month, and custom-priced Enterprise Grid. Salesforce bundles Slack free with every new Enterprise and Unlimited Edition Salesforce org, creating a powerful distribution channel into the CRM install base. Revenue is supplemented by consumption-based Agentforce pricing at approximately $2 per AI conversation. Salesforce CEO Marc Benioff stated Slack revenue is expected to reach $3 billion in 2026, representing 2.5x growth since the acquisition. Go-to-market combines enterprise field sales, self-serve freemium onboarding, and the Slack Marketplace, which hosts 2,600+ app integrations. Slack serves enterprise, mid-market, and SMB customers across industries including technology, financial services, media, retail, manufacturing, and automotive, with named users including OpenAI, Anthropic, IBM, GM, Paramount, Stripe, Target, and Rivian.

Engineering and product operations span San Francisco (HQ and primary engineering), Seattle (AI/ML hub), Atlanta (desktop client and security), the Washington DC metro area (cloud infrastructure), and Dublin (EMEA headquarters), with hiring signals concentrated in AI platform, LLM fine-tuning, and machine learning infrastructure roles.
