We are two software engineers frustrated with "grooming meetings" that were one-sided and ceremonial. So, we hacked together a polling engine for asynchronous voting, satisfying the needs of our day jobs. Since then, we've seen companies adopt Groomba in different ways, and after implementing some feature requests, we realized we created something highly adaptable to many workflows.
We're offering Groomba free for your first team of users (however many people you want in a Slack channel) as we're confident Groomba can easily fit into your agile process. If not, just message us :)
