Interesting. Would you know how this compares to turnstile [0]? (I only know about them because I saw their hiring page on HN a week or two ago, and was intrigued.)
Don't have much information about them, but it seems that we are API first while they are focusing on no-code (from what I understand from their homepage). The common path would be that we both have a UI to let non-tech users handle billing actions without engineers.
