Slack Review (2025): Features, Pricing, Pros & Cons of the Top Team Collaboration Tool
Slack is one of the most recognized team communication platforms in the world, trusted by startups and enterprises alike to streamline conversations, projects, and workflows.
As a cloud-based collaboration hub, Slack centralizes team messaging, integrates with thousands of tools, and enhances productivity with automation features.
It solves a major challenge of modern organizations: scattered conversations across emails, meetings, and disconnected tools. With Slack, communication becomes organized, searchable, and actionable.
Ideal for remote teams, hybrid offices, small businesses, large corporations, and cross-functional departments, Slack has become a digital headquarters for companies looking to move faster and work smarter.
About the Company
Slack Technologies was founded in 2013 by Stewart Butterfield, Eric Costello, Cal Henderson, and Serguei Mourachov. Interestingly, Slack emerged from the ashes of a failed multiplayer game called Glitch.
The internal communication tool the team built during development turned out to be more useful than the game itself—and so Slack was born.
Headquartered in San Francisco, California, Slack has since grown into a tech titan in the collaboration space. In 2021, Salesforce acquired Slack for $27.7 billion, cementing its role as a core part of the Salesforce digital ecosystem.
Today, Slack continues to evolve with a mission to make work simpler, more pleasant, and more productive.
