100 employees is a bit much for Brainy Actz. In fact I can't think of any escape room that could accommodate such a large number unless you ran them in teams of 6-8 all day long.
The place is small. But, they may have other places where they can host. Best to contact them.
You may need to reach out to them directly but I feel like that would be really cramped in the space, we were with a group of about 10.
