Why does Teams have more users than Slack?

Microsoft Teams is bundled with Microsoft 365, which is used by 300M+ business users globally. Slack grew organically without this distribution advantage.

Which is better for remote work?

Both are excellent. Slack edges out Teams for UX and integrations; Teams wins for video meetings and organizations already using Office.

Slack vs Microsoft Teams

Enterprise team messaging platform with AI collaboration features and extensive integrations

Startups, tech companies, and developer teams

Check Price

Microsoft Teams

Short Answer

Slack is the pioneer of team messaging with a cleaner interface and better third-party integrations. Microsoft Teams has 320M+ daily active users — largely due to Office 365 bundling — and better video conferencing. Teams is free with Microsoft 365; Slack charges for most features.

Our Verdict

Slack for startups and developers who value integrations and UX. Teams for enterprises already using Microsoft 365. Teams wins on scale; Slack wins on experience.
