Slack, the popular workplace communication tool, is now valued at more than $7 billion.
The company announced Tuesday it closed a new $427 million funding round, making it one of the most valuable privately held tech start-ups ー and strengthening its position against tech titans like Microsoft, Google, and Cisco, all of which have their own enterprise products competing in the space.
San Francisco-based Slack, which allows members to talk in private chats and group channels, [said in a blog post](https://slackhq.com/slack-raises-series-h-round-of-financing-from-new-investors) it would use the capital investment to grow its business, which now has more than 8 million daily active users and 70,000 organizations paying for access.
The new valuation, up almost 40 percent from the $5.1 billion it was worth last year, makes Slack more valuable than Vice Media, fintech firm Robinhood, and online sports marketplace Fanatics, according to CBInsight's [Global Unicorn Club](https://www.cbinsights.com/research-unicorn-companies).
The funding round was led by General Atlantic and Dragoneer Investment Group and included T. Rowe Price, Wellington Management, Baillie Gifford and Sands Capital. Last year, Slack got a $200 million cash infusion from [Softbank's Vision Fund](https://www.recode.net/2017/9/18/16324754/softbank-slack-investment), the massive venture capital fund that has pumped billions into some of the most high-profile unicorns in Silicon Valley. It's raised more than $1 billion to date.
Nvidia on Wednesday became the first public company to reach a market capitalization of $5 trillion. The ravenous appetite for the Silicon Valley company’s chips is the main reason that the company’s stock price has increased so rapidly since early 2023.

A big-screen adaptation of the anime “Chainsaw Man” has topped the North American box office, beating a Springsteen biopic and “Black Phone 2.” The movie earned $17.25 million in the U.S. and Canada this weekend. “Black Phone 2” fell to second place with $13 million. Two new releases, the rom-com “Regretting You” and “Springsteen — Deliver Me From Nowhere,” earned $12.85 million and $9.1 million, respectively. “Chainsaw Man – The Movie: Reze Arc” is based on the manga series about a demon hunter. It's another win for Sony-owned Crunchyroll, which also released a “Demon Slayer” film last month that debuted to a record $70 million.
The Federal Aviation Administration says flights departing for Los Angeles International Airport were halted briefly due to a staffing shortage at a Southern California air traffic facility. The FAA issued a temporary ground stop at one of the world’s busiest airports on Sunday morning soon after U.S. Transportation Secretary Sean Duffy predicted that travelers would see more flights delayed as the nation’s air traffic controllers work without pay during the federal government shutdown. The hold on planes taking off for LAX lasted an hour and 45 minutes and didn't appear to cause continued problems. The FAA said staffing shortages also delayed planes headed to Washington, Chicago and Newark, New Jersey on Sunday.
Boeing workers at three Midwest plants where military aircraft and weapons are developed have voted to reject the company’s latest contract offer and to continue a strike that started almost three months ago. The strike by about 3,200 machinists at the plants in the Missouri cities of St. Louis and St. Charles, and in Mascoutah, Illinois, is smaller in scale than a walkout last year by 33,000 Boeing workers who assemble commercial jetliners. The president of the International Association of Machinists says Sunday's outcome shows Boeing hasn't adequately addressed wages and retirement benefits. Boeing says Sunday's vote was close with 51% of union members opposing the revised offer.
