Get ready to hear Slack notifications if you work at Meta.

The tech giant is switching over from Google Chat to Slack for internal communications, according to a memo its AI chief, Alexandr Wang, sent out this week.

Meta is making the move because it says Slack is better for handling AI agents, the memo reads.

"Slack is the strongest platform available today for agents, which is why we're deciding to make the switch," it says. "Slack has a rich conversational interface for agents, mature developer tooling and strong 3P integrations. While not all of us are building agents today, everyone at the company will benefit from a robust and useful agent ecosystem."

Wang's comment about "strong 3P integrations" refers to third-party integrations, meaning Slack is not only attractive because of the tool itself but because it already has a large range of external tools and AI agents that can plug directly into it.

The move is a major win for Slack owner Salesforce, which has been investing heavily in AI features and products. Salesforce bought Slack for $27.7 billion in 2021.

Meta and Salesforce declined to comment. Google didn't respond to a request for comment.

The migration also shows how Slack has capitalized on the current craze for AI agents. The product has made it easy for users to integrate AI agents into it to automate tasks, request data, and provide teams with updates.

Salesforce's stock has fallen over the past year amid concerns about whether those AI agents will eventually replace the software that many workers use.

The company's stock surged nearly 23% in a single day last week following an expanded partnership with Anthropic and an earnings release reporting strong results, including new annual order growth and rising subscription and support revenue.

"This is not the SaaSpocalypse," Salesforce CEO Marc Benioff said. "We've been hearing about this for the last two quarters, these dire predictions about the end of software, and how the models eat everything, but none of them have come true for us."
