Is it getting ready to expand its corporate offerings?

Facebook has registered a handful of domain names suggesting it’s working on a service called WorkPlace…or a rebrand.

The social media company registered the domain names facebookworkplace.com, fbworkplace.com, workplacebyfacebook.com and workplacebyfb.com, along with these domains in other extensions, yesterday.

Facebook already has a service called Facebook at Work, which looks a lot like Slack.

Perhaps Facebook is getting ready to double down on solutions for companies? Earlier this year, Slack raised $200 million at a $3.8 billion valuation, so there’s clearly a market for corporate collaboration tools.

Facebook also just won a UDRP for Facebookwork.com.
