For any small team wanting to try Copilot, heed my warning that you will waste hours navigating their billing settings using various out-of-date documentation. Long story short, I finally got an email from them saying that "Copilot Business is available for teams purchasing 10 or more licenses". This is undocumented but other people are reporting the same: https://github.com/orgs/community/discussions/199346

We're sticking with Cursor for now, using Kimi as our daily driver (branded as "Composer").
