Ask HN: Does anyone using GitHub projects feature?

I've worked with many teams for the past 15 years but never saw anyone using Github projects feature. Does anyone really using it? We are paying to other project/task management tools and really want to have them in one place but there are non-technical people in the team. I can use both but it will be a challenging to use different tools for different teams and also I can't find a reason to use Github for managing projects. What type of companies use github and what are the benefits?
