I use it internally to show interactive results and explain stats concepts to PMs/Eng, so for example I was trying to explain exactly how increased sample sizes change the confidence intervals around a binomial proportion as the proportion changes from .5 -> 1, and then relate that to how much it costs for the business, etc. So I made a Streamlit app in a few minutes, and let them interact with it.
