Slack is the operating system for modern business communication. It organizes conversations into channels (like #marketing, #general, #random) so everyone knows where to find information. Unlike email chains, Slack is real-time and transparent.
It integrates with virtually every other tool in this directory. When a sale happens in Shopify, a notification pops up in Slack. When a task is completed in Asana, Slack updates. It is the central nervous system of a tech company.
Key Features:
- Channels: Organized spaces for every project and topic.
- Huddles: Quick audio/video chats for impromptu meetings.
- Integrations: Connects with Google Drive, Trello, Zoom, and 2000+ apps.
Verdict: If you have a remote team, Slack is mandatory.
