totally fair, keeping it here helps everyone!
i went ahead and grabbed a screenshot to show you what the screen looks like. close the Sculptor sidebar on the right first so you have a full view. you'll then see two main areas: the yellow part on the left is your filters, and the red part is the preview table showing results in real time as you adjust those filters.
for now, just go to the Job Title filter on the left and type in Owner, Founder, CEO, Director or anything that signals the business owner. the preview table will update as you go.
one important note: if you're planning to use your BuiltWith domains as the source, filtering by domain in Find People can pull in a lot of noise. people from unrelated companies can show up just because they're associated with that domain. a cleaner approach is to use the company's LinkedIn URL as your source since it's more precise.
that means you'd first need to get the LinkedIn URLs for your companies into your table. you can do that with Claygent, a Google search column, or another enrichment source.
if your WordPress sites are mostly small local businesses, there's a good chance many won't have a LinkedIn presence at all. in that case you have two options: use Apollo (with your own account) to search by domain, or use Claygent to visit each website and find the owner from the site itself or other online sources like Facebook or local directories.
claygent is probably the most flexible option for small business owners specifically since it's not limited to one data source.
