In a world where the ability to reach each other almost instantly is the standard, a company like Slack was bound to appear.
Slack is a team collaboration tool for companies that allows group chats, private messaging, and file sharing. Within the first 24 hours in 2013, they gained 8,000 customers. It is one of the fastest growing enterprise applications of all time - and only continues to get larger.
Even though the company has a free tier of service, there are paid options with more features. The free tier allows for search of 10,000 most recent messages, application access for iOS, Android, and Mac and Windows Desktops. Slack also allows for multi-team support. The priced tiers of service offer options such as guest access and advanced statistics and metrics.
There are four founders: Stewart Butterfield, Eric Costello, Cal Henderson, and Serguei Mourachov. Butterfield is widely known as one of the founders of Flickr. Slacks original campaign raised 43 million in 2014, and the company is now worth almost 3 billion dollars. Growth of the application has been put at 10,000 new users everyday. This past summer, the company reached 1 million active users and continues to grow!
