Meta drops Google Chat for Slack, citing agent ecosystem

Meta's AI chief Alexandr Wang told staff this week that the company is moving off Google Chat and onto Slack. The reason he gave was agents.

"Slack is the strongest platform available today for agents, which is why we're deciding to make the switch," Wang wrote in the memo, reported by The Next Web. He pointed to "a rich conversational interface for agents, mature developer tooling and strong 3P integrations," and told employees that "while not all of us are building agents today, everyone at the company will benefit from a robust and useful agent ecosystem."

The switch is a marquee win for Salesforce, which bought Slack for $27.7 billion in 2021 and has spent the years since trying to make agent orchestration the reason enterprises keep paying for it. Meta and Salesforce declined to comment; Google did not respond.

The same piece pairs the Meta decision with public-sector buyers in Europe moving the opposite way. France has ordered its ministries to replace Teams and Zoom for 2.5 million civil servants by 2027, migrating to Tchap, a messenger built on the Matrix protocol running on sovereign infrastructure. The German state of Schleswig-Holstein moved 110 million emails off proprietary software last year, saving €15 million in licensing fees. The EU Data Act caps switching costs and requires providers to complete transfers within 30 days; from January 12, 2027, switching charges are prohibited entirely.

Neither the memo nor the reporting says when Meta's migration completes, how many seats are involved, or what the company will pay Salesforce. It sits inside a busy run of collaboration-surface stories on our enterprise-AI tracker, alongside today's news that Anthropic's EFS lets banks keep Claude logs in their own clouds, where the argument between vendors is increasingly about which chat window an agent can actually reach into.
