Customers for simple AI?

Hello IndieHackers!
I'm planning to build a simple web service that essentially wraps artificial intelligence in a clickable interface. Unlike Azure or GCP, this would be aimed at people that are not programmers/data scientists. They would only be required to provide some data to build a model from. I'm wondering if you have any ideas about potential customers. What I got so far:

1. Investing/trading. This where I come from. I trained AI to improve my trading and I think other traders can be interested.
2. Marketing people. They probably have lots of data about their marketing campaigns. Perhaps AI can learn something there and provide some answers to improve their results.
3. Professional sport gamblers
   ... any more?
