How can I find customers for my AI similar phrase matching tool?

I made an AI model that takes in 2 strings and can determine if they're similar. For example: "Manchester United" = "Man Utd". Came up with this after struggling with getting team names to match when analyzing sports betting data. Without AI, I would've had to manually record that "Manchester United" is the same thing as "Man Utd", "Man U", "Manchester United FC", and so on, and for every sports team.

So far, I've tried the following to find potential users:

• emailed every single sports betting data API on rapidAPI
  A few of them replied back, saying that they already built this functionality without AI and didn't need my model.
• emailed a data analyst/expert witness I kind of know
  He said he already had something similar
• emailed the team at dedupe.io, which does something similar
  haven't heard back from them

Thinking of trying some subreddits, but I wanted to see if you could give me some better advice on how to go about finding people who might pay for my AI model.

Please also try and roast my idea :)
