Slack’s business model is simple: Be Less Busy. It’s hard to imagine any busy professional not coveting those simple words. Slack’s promise is to make business professionals more productive by eliminating meetings and emails. Can you imagine a life without meetings? That is Slack’s promise and it is taking the business world by storm. Slack, a SaaS application, is one of the fast-growing collaboration companies ever started used by millions of people every day to collaborate at work. In two short years since its inception Slack has become a $3 Billion Dollar company. Slack is like Twitter for businesses. Slack is a centralized group chat platform for the enterprise. With its advanced search and file-sharing functionalities, it can also be linked to third-party apps, like Google Drive, Dropbox, and Twitter. Slack has long advertised itself as a “freemium” product, where an unlimited number of users can use it for free before deciding to upgrade and pay money for more robust package with better features. In time—and it won’t be long—Slack will morph into the spinal cord of the office nervous system, connecting numerous third-party business apps, eventually becoming the gateway to a workplace artificial intelligence system that will answer routine questions and proactively seek out information you might otherwise miss. Slack’s founder Stewart Butterfield, also the founder of Flickr, was actually building a gaming company when the team created Slack to help developers and employees communicate. When the gaming company went bankrupt Butterfield used the opportunity to launch the company’s home-grown collaboration tool Slack and the rest is history. And like a game Slack is fun and engaging and beating-up its boring traditional enterprise application competition. Slack only charges customers after Butterfield attributes his company’s success to its focus on education, feedback, customer happiness, and metric analysis. Butterfield’s vision is for Slack to become the single source of company information. Required: 1. You have landed your dream job working for Steve Evert. Unfortunately, Steve doesn’t understand why ebusiness models are important for a business. Explain to Steve the importance of ebusiness models and the model implemented by Slack. 2. Steve would also value an overview of the different types of ebusiness revenue models and be sure to describe the revenue model implemented by Slack.
