Company Description
Slack Technologies is an international software company that develops an AI-powered productivity platform. Now a subsidiary of Salesforce, the company provides a Software as a Service (SaaS) tool for messaging, file sharing, project management, and application integration, serving sectors that include manufacturing, media, and financial services. As of the first quarter of 2022, the platform had 169,000 paid customers. The company was founded in 2009, and its core team was largely drawn from the founders of Ludicorp, the company that created Flickr. Slack was originally developed as an internal tool for a gaming company called Tiny Speck before it was publicly launched and eventually acquired by Salesforce.
The company's recent developments focus on expanding its platform's capabilities, particularly in artificial intelligence and automation. Slack has promoted new AI-powered features, such as automatic recaps of channels, threads, and direct messages. It also highlights customer use cases, such as the company Devolutions, which uses Slack with 42 custom workflows and 60 integrations. This focus on ongoing product development is also reflected in regular updates, like the "December Slack Feature Drop," which introduced new productivity tools to the platform.

Frequently Asked Questions
Joining Anduril as an employee is another way to acquire equity, typically through stock options included in compensation packages.
Is Slack worth joining?
Deciding whether to join any company depends on your personal career goals and how you value their compensation, culture, and growth prospects. Tools like Prospect can help you evaluate the equity portion of a compensation offer by forecasting its potential value.
What should I do with my Slack stock?
Since Slack was acquired by Salesforce, any private Slack shares would have likely converted to cash or Salesforce stock (ticker: CRM). For managing equity in other private companies, platforms like Prospect provide tools for tax-optimized strategies and scenario planning to help you make informed decisions.
Can you sell Slack stock?
As Slack is now part of the publicly-traded company Salesforce, any shares you hold would likely be Salesforce stock, which can be sold on the open market. For employees of private companies, selling stock is often restricted to specific events like tender offers, which platforms like Prospect can help you navigate.
How can I find the value of my Slack stock?
Since Slack was acquired by Salesforce, the value of your holdings is tied to the public market price of Salesforce's stock. For private company stock, you can use tools like Prospect, which uses predictive models to help you forecast your equity's potential value.
What is Slack's equity worth?
The value of equity from Slack is now determined by the stock performance of its parent company, Salesforce. To understand the potential worth of equity in a private startup, Prospect offers personalized tools to model your specific holdings and financial scenarios.
What is Slack's stock ticker symbol?
Prior to its acquisition by Salesforce, Slack traded under the ticker symbol WORK. The company is no longer publicly traded on its own, and its former stock was converted as part of the acquisition by Salesforce (ticker: CRM).
Can I buy or sell Slack stock?
You can no longer buy or sell stock in Slack as an independent entity, as it was acquired by Salesforce. You can, however, buy and sell shares of Salesforce (CRM) on the public stock market.
What is the criteria to buy or invest in Slack stock?
To invest in what was formerly Slack, you would now purchase shares of its parent company, Salesforce (CRM), through a standard brokerage account. Investing in a private company typically requires being an employee or an accredited investor, and platforms like Prospect are designed to help employees manage the equity they receive.
