Position: CTO at Slack
Slack is a messaging app for businesses, officially released in 2014.
The goal of the app is to become a substitute for corporate e-mail and Skype.
A big advantage of the app is Working Groups, which you can set up an unlimited number of times. To join one of those groups, you have to enter its name, your login name and the password.
The app works on PCs (running on Windows and Mac OS) and smartphones (Android, iOS). There is also a browser version.
Slack can be downloaded for free; however, there are a few restrictions. To remove them, you will have to pay $6.67 or $12.5, depending on the pricing plan you choose.
The only problem with Slack is that you can’t choose any other language but English.
