FAQS

GENERAL

What is the news?

Salesforce, the #1 CRM, is acquiring Slack, the most innovative enterprise communications platform, to create the operating system for the new way to work. The combination will enable companies to grow and succeed in the all-digital, work-from-anywhere world.

Who is Slack?

Slack brings all of a company’s people, data and tools together so teams can collaborate and get work done, from anywhere. Slack Connect extends the benefits of Slack to enable communication and collaboration between a company’s employees and all its external partners, from vendors to customers.

How many employees does Slack have?

Slack has over 2,500 employees in 12 countries globally, with headquarters in San Francisco, California.

Why is Salesforce buying Slack?

The events of this year have greatly accelerated the move by companies and governments to an all-digital world, where work happens wherever people are—whether they’re in the office, at home or somewhere in between. They need to deliver connected experiences for their customers across every touchpoint and enable their employees to work seamlessly wherever they are.

Together, Salesforce and Slack will give companies a single source of truth for their business and a unified platform for connecting employees, customers and partners with each other and the apps they use every day, all within their existing workflows.

When will the transaction close?

The transaction is anticipated to close in the second quarter of Salesforce’s fiscal year 2022 (the quarter ending July 31, 2021), subject to Slack stockholder approval, receipt of required regulatory approvals and other customary closing conditions.

How much is Salesforce paying for Slack?

Please refer to our press release.

2/44

How will this transaction benefit Salesforce employees?

Acquisitions like Slack are a core part of our strategy—they complement our organic innovation and bring smart new people to Salesforce. Slack has a world-class leadership team and talented employees.

Together, Salesforce and Slack will give companies a single source of truth for their business and a unified platform for connecting employees, customers and partners with each other and the apps they use every day, all within their existing workflows.

There is also close cultural alignment between our two companies. We both operate with a strong set of core values and a relentless focus on customer success.

Will we merge their teams into ours?

Upon the close of the transaction, Slack will become an operating unit of Salesforce and will continue to be led by CEO Stewart Butterfield.

Will the Slack brand continue to exist?

For now, there will be no changes to the Slack brand.

Can we start using Slack?

As communicated on October 28, 2020, we had independently planned to enable the entire organization on Slack, and we will continue ahead with that roll-out. More information will be available soon.

Can I trade Salesforce stock or Slack stock between sign and close?

Salesforce employees should exercise extreme caution if trading in Slack or Salesforce securities, even during the open trading window. Any trading on material non-public information regarding Salesforce or Slack is prohibited under our insider trading policy. Please contact XX with any questions.

Any Salesforce employees to whom the transaction was disclosed prior to its public announcement and had access to material nonpublic information regarding Slack that has not yet been disclosed should continue to not trade in Slack or Salesforce securities, even during the open trading window. This group of people would include those with access to financial models, projections and similar information relating to Slack.

TECH & PRODUCT

Is the Salesforce product roadmap going to change?

Slack will be deeply integrated into every Salesforce Cloud. As the new interface for Salesforce Customer 360, Slack will transform how people communicate, collaborate and take action on customer information across Salesforce as well as information from all of their other business apps and systems to be more productive, make smarter, faster decisions and create connected customer experiences.

Will we continue to use Chatter and Salesforce Anywhere collaboration?

Yes, we will continue to use Chatter and Salesforce Anywhere for our current processes. As we build our integrations and move functionality from Chatter and Anywhere into Slack, we will start using Slack for more of our processes. Eventually, we believe that the Salesforce Anywhere, Chatter, and Slack products can be combined, to provide a single, world-class communication experience for the Customer 360.

What does this mean for Lightning Experience?

Lightning Experience will continue to be a critical layer of Customer 360, providing out of the box interfaces for apps like Sales, Service and Marketing; a component framework for building custom apps; and a design system to create new interfaces consistent with Lightning design principles.

What does this mean for our Employee Experience offering?

Slack’s integration with over 2,400 services and capabilities like Workflow Builder will allow us to build even more collaboration and productivity into Employee Experience apps built on Customer 360.

Subject line: A big day for Salesforce

Hi <<XX>>,

Today is a big day for Salesforce. We announced another record quarter and signed a definitive agreement to acquire Slack, the most innovative enterprise communications platform.

Q3 was a phenomenal quarter, and now we’re raising our FY21 guidance to $21.11 billion at the high end and initiating FY22 guidance at $25.5 billion. No other major enterprise software company is growing at this rate.

We’re rapidly moving to an all-digital world, where work happens wherever people are. Our results are being driven by the success of our customers and the relevance of our Customer 360 Platform in this new normal.

Companies like Prudential, Accenture, NBC Universal, Telefonica and Zoom, along with governments like the State of California, chose Salesforce in the quarter to help them succeed and grow.

I couldn’t be more excited about our agreement to acquire Slack. Stewart Butterfield and his team have built one of the most beloved platforms in enterprise software history, with an incredible ecosystem around it. Salesforce and Slack are also neighbors in San Francisco—we can wave to each from our offices.

This is a match made in heaven. Together, we’ll shape the future of enterprise software and transform the way everyone works in the all-digital, work-from-anywhere world.

Combining Slack with Salesforce Customer 360 will be transformative for our customers and the industry—creating the operating system for the new way to work. Together, we’ll give companies a single source of truth for their business, and a unified platform for connecting employees, customers and partners with each other and the apps they use every day, all within their existing workflows.

We look forward to welcoming the Slack team to the Salesforce Ohana once the transaction closes, which is expected to occur in the second quarter of FY22.

You can find more information about the Slack news in our press release and employee FAQ.

I also want you to know that our Chief Financial Officer, Mark Hawkins, has decided to retire. He’ll remain our CFO through the end of our fiscal year, which ends January 31.

At that point, Amy Weaver, currently our president and Chief Legal Officer, will become our president and CFO. Mark will remain with us as an advisor through October 2021, giving us plenty of time to ensure a smooth transition.

I want to thank Mark for his important role in our success over the past six years. I’m forever grateful for his leadership and friendship. I’m equally grateful that we have such a strong leader in Amy to turn to as our next CFO. She has played an integral role in the operations of our company as we’ve scaled, and I couldn’t be more thrilled to have her as our next CFO.

Finally, I want to invite you to tune in at 9:40 a.m. PT tomorrow for our first-ever virtual Dreamforce keynote — to hear more about Slack and watch as we celebrate our customers’ success and unveil even more new innovations across Customer 360.

Message from Salesforce CEO to Slack CEO for All Slack Employees

From: Salesforce CEO

To: Slack CEO

Posted to: All Slack Employees, via Slack

Stewart—Congratulations to you and the entire Slack team! This is a monumental day for our companies, our customers and the industry.

Will you please pass this note along to your team?

—Marc

Slack team—

We’re thrilled by the opportunity to bring Salesforce together with Slack. Combining Slack with Salesforce Customer 360 will be transformative for our customers and the industry — creating the operating system for the new way to work, a single source of truth for a company’s customers and employees, and a unified platform for connecting everyone inside and outside of a company with each other and the apps they use every day, all within their existing workflows.

I hope you’ll tune into tomorrow at 9:30am PT, when Stewart will be joining our virtual Dreamforce keynote, alongside Salesforce President & COO Bret Taylor and I. We’ll also be joined by special guests to celebrate our customers’ success and unveil new innovations across Customer 360.

And on December 4, Bret will join Stewart for a fireside chat to share more about our vision for the future. Bret joined Salesforce in 2016 via the acquisition of Quip, which he co-founded. Prior to Quip, Bret served as Chief Technology Officer of Facebook, where he was credited with the invention of the “like” button. Bret started his career at Google, where he co-created Google Maps. Please join us: https://www.salesforce.com/dreamforce/

I want to thank each and every one of you for your contributions to this phenomenal company. I’m inspired by what you’ve built and we’re excited to welcome the Slack team to the Salesforce Ohana once the transaction closes.

With gratitude,

Marc
