I'm curious about the involvement of tech companies here. Obviously approximating posterior distributions of explicit statistical models via simulation techniques is common in academic scientific literature but I'd like to hear about examples of it being done in "production" settings, i.e. not just as a one-off analysis. I have for a long time had a vague belief that in production settings people usually opt for heuristics / point estimates etc but I haven't had much involvement with this sort of thing for a while.
