Brett R. David already outlined some of the reasons why you didn't see great results here (Logan is pretty specific and we're working on making improvements to our dataset to support searches like this) but here's an example of another search you can try:
Find owners or presidents of accounting firms that are based in Utah that use Xero or Quickbooks and have 10+ employees
This one produced 129 results for me: it's still pretty specific since we're narrowing down based on tech stack (note that either the person or the company is based in Utah in this search). Hope that's useful! Happy to share more ideas here if you need them
