Slack - About and How it Works?

Slack Technologies is an American international software company that designs and develops a communication platform that provides real-time messaging, file sharing, archiving, and searching services for teams. Slack offers a team communication tool that consists of a set of open, documented application programming interfaces (APIs), developer tools, and an App Directory that lists apps that have met the guidelines.

Organizations on Slack use its platform to create internal applications and integrations, ranging from simple notifications to complex internal workflows. Third-party developers build integrations and applications that make it easier for their existing customers to engage with their products as well as find new customers.

Slack is a layer of business technology, where people work together to connect all their other software tools and services and find the information they need. Slack users communicate with one another by posting messages to a channel or sending direct messages to a person or a group of people. Slack’s core organizing principle is the channel, which brings the right people together to collaborate, share information, and get work done. Channels offer flexibility and can be organized by project, topic, team, or whatever makes sense for a specific task or situation.

Slack enables communication and collaboration among organizations via shared channels and guest accounts. Shared channels securely connect the Slack workspaces of different organizations, enabling the same level of communication and collaboration between enterprises that Slack brings to teams within an organization.

Slack - Logo and its Meaning

Slack's logo resembles a hashtag or octothorpe. The hashtag is an organizing element in the platform, signaling the beginning of the channels where teams can talk about individual projects.

Slack - Founder and History

Slack is famous for reaching a valuation of $1B after just eight months without spending a penny on traditional advertising or a Chief Marketing Officer. Slack was a runaway success because it had a multi-year head start on everybody else.

Stewart Butterfield | Founder & CEO, Slack 

Slack founder and CEO Stewart Butterfield and his team set out to create something new and original for the massively multiplayer online role-playing game (MMORPG) market. As it turns out, they revolutionized how companies communicate at work instead.

Video game developers might not seem like the most logical group to make a sticky, engaging communications tool for today’s workplace, but Tiny Speck’s expertise in gaming was a major competitive advantage. Butterfield and his team already knew how to make repetitive tasks fun and engaging, as this is core to the gameplay experience of the MMORPG genre. Making work-based communication fun and engaging would be the secret sauce that made Slack so wildly successful.

The Comparison Between WhatsApp And Telegram
Currently, there are so many messaging apps and services are available. But this field becomes a bit narrow if privacy and security are your main concerns. WhatsApp and Telegram are considered as the major apps in instant messaging apps. Let us discuss more about these two messaging tools.

Slack - Mission

Slack's mission statement says,

" We live by our mission, and improving people's working life starts with our own company. We're building a platform and products we believe in – as well as a strong, diverse team of curious, creative people who want to do the best work of their lives and support each other in the process. "

Slack - Business Model

Slack advertises that it is completely free to use for as long and with as many people as you want. So how does it make money?

Well, a percentage of organizations pay premiums for special features. Such features include access to an unlimited communication history, unlimited app integration, additional file storage, screen sharing, statistics, and more. With no apparent plans to run ads shortly, Slack relies on a simple business model, charging monthly fees of $7.25 per user for the standard subscription and $12.50 per user for the plus subscription. It has also launched Enterprise Grid for larger organizations that have tens of thousands of users.

Slack - Future Plans

“People deserve to do the best work of their lives,” Slack co-founder and chief executive officer Stewart Butterfield said in a video released alongside a live stream of its investor day event. “This desire of feeling aligned with your team, of removing confusion, of getting clarity; the desire for support in doing the best work of your life, that’s universal, that’s deeply human. It appeals to people with all kinds of roles, in all kinds of industries, at all scales of organization and all cultures.”

Slack currently boasts more than 12 million daily active users across more than 600,000 organizations — over 88,000 on the paid plan and more than 550,000 on the free plan.

There are a lot of privacy and security aspects to these Slack-based communications, and Slack will provide granular options for IT admins to manage exactly what’s shared. Slack is also improving its channels’ user interface, so it’s very clear when you’re using a shared channel and who is participating in the channel.

There’s even some machine learning going on that will allow Slack to scan calendars across multiple organizations and help workers create meetings at appropriate times when everyone is free. Slack apps can also be shared across organizations, as long as both parties have them installed in their Slack instance. Slack has a big incentive to gradually move businesses away from email.

“We believe that whoever is able to unlock that potential for people … is going to be the most important software company in the world. We aim to be that company,” he added.”


Being the fastest-growing startup in history isn’t the only thing that makes Slack unique. Its product development process was unorthodox. Slack was born out of a gaming company called Tiny Speck. Butterfield and his team didn’t intentionally set out to create a SaaS product for the workplace. They built a tool for themselves. They only realized their tool’s commercial potential later on.
