Do you mean workspace?  In that case it's one on the new team, unlimited on Business.  You should have unlimited bases per workspace even on team.

Hi BillH, you're right. I was talking about workspaces. My question is about the price. We are a two person team and I believe the cost is $20 for each workspace created. It's right? Thank you.

That is my interpretation.  I'm not with Airtable, just trying to do some evaluations for different client situations, and that's how I'm reading it.
