Google on Wednesday said it will be making its team communication app for work available to customers of its G Suite portfolio of cloud productivity apps this week.

The Hangouts Chat app gives Google a direct competitor to privately held Slack and the many Slack alternatives that have emerged in recent years, including Microsoft Teams, which is part of the Office 365 portfolio. Google now gets more than $1 billion in revenue from G Suite and the Google Cloud Platform.
