It's a bot integration for Slack that manages asynchronous stand-up meetings. Geekbot seamlessly creates a standup meeting with the members of your team. All you have to do is answer a set of questions that the bot then broadcasts to a channel.
This allows for a non-intrusive process that helps your team stay focused on the real tasks.
