Intuitive, marketing aid and gorgeous landing page. I have my hands in a few pies. I got the Tier 2. I could connect all accounts (different companies) and also add users (within each company) to join. I am being clear here as I almost didn't get this when I thought this was not an option. It is. The team are super helpful also. Brilliant design options. You can also design landing page for the brand (each company) as a whole PLUS design each user's calendar to suit their own branding.
