Slack

Slack is a workplace productivity platform, part of Salesforce, built around the goal of making working lives simpler, more pleasant and more productive. The product organises work into channels, shared spaces where teams, AI assistants and agents work together, and adds huddles, a built-in video tool. Collaboration software of this kind is typically adopted by organisations looking to reduce internal email and keep project discussion, files and decisions in one searchable place.

Beyond messaging, Slack offers no-code automation through workflows, task tracking through lists, templates and AI-powered search intended to make knowledge sharing easier across a company. Its AI features include conversation summaries, note-taking in huddles and Slackbot, which the company presents as a personal agent that coordinates work across connected apps and agents. Slack is integrated with Salesforce Customer 360 and brings CRM data into conversations for sales, service and marketing teams, tying the messaging layer to the parent company's customer management products.

The platform connects to more than 2,500 apps through its marketplace and API, and Slack Connect lets companies work directly with outside clients and vendors. Slack reports more than 200,000 paid customers, use by 77 of the Fortune 100 and daily active users in more than 150 countries, and it can be tried for free. The company works from Salesforce offices around the world and runs the Slack Fund, a venture capital fund that invests in software entrepreneurs.

Slack describes diversity and inclusion as core to its values, presents itself as an equal opportunity employer, and runs Slack for Good, which aims to increase the number of historically underrepresented people in technology. For a company whose product is about how people work, this emphasis on its own working culture is consistent with its stated mission.
