Slack Technologies, a corporate messaging and collaboration software start-up, has received inquiries about a potential takeover from technology companies including Amazon.com, Bloomberg reported on Thursday.
A deal could value the company at at least $9 billion, Bloomberg reported citing people with knowledge of the matter.
Slack is a platform where employees can send messages, collaborate, organize and share files. The technology also integrates with a wide variety of business software — such as Salesforce.com and Microsoft's Skype — so employees can do all their work within Slack.
San Francisco-based Slack has raised more than $500 million from venture capitalists and was valued at $3.8 billion at its last private financing round a year ago.
Both, Amazon and Slack were not immediately available to comment outside of regular U.S. business hours.
