Has Anyone Deployed AI in a Small Business and Seen Real Value?

Over the last year we all followed the wave of AI news. I was wondering what use-cases really landed in production so far? Do you know real-world examples of deployed generative and agentic AI that provides value especially for small business owners (if possible provide a reference)? Please mind that I am not so much interested in software or developer related startups, as there are millions of those around. I am specifically searching AI use-cases for businesses operating in: - small retailers - hospitality - restaurants and food-trucks - travel - entertainment - beauty - fitness - accounting and bookkeeping - manufacturing - industrial & machinery - logistics - agricultural - education
