Slack Technologies, Inc. -- the creator of the collaborative chat site for work teams -- plans to go public on the New York Stock Exchange for the direct listing of its shares, according to a report on Monday.

According to a story in the online edition of the Wall Street Journal citing people familiar with the matter, Slack's IPO is expected sometime this summer.

Slack representatives declined to comment on the report.

Slack announced in February that it would go public, disclosing that it confidentially submitted a draft registration statement on Form S-1 with the U.S. Securities and Exchange Commission for the public listing of its Class A common stock. At the time, the California-based company said it would go public following SEC review process.

Slack has more than 10 million daily users, 85,000 paid subscribers around the world, and claims Panasonic, Nikkei, and Target Corp. (TGT - Get Report) as among its customers, according to its website.
