To get your team collaborating more in Slack start a leaderboard on praises. With Slack integrated in you Spinify account your team will be able to 'Praise' each other. Leaderboards using the /praise comments made by colleagues on posts in your Slack channels engage and motivate employees to communicate in the business workplace. The more /praise comments a team member receives the higher they climb in the leaderboard.
