Hi @nathandetroyer, fellow user here.
Can you post a couple examples of what your frontmatter looks like? Your WHERE clause looks reasonable, but I wonder if it’s a data issue. This clause expects each Company field to contain a list of companies, and won’t work if the company field has a single item.
For example, this frontmatter entry looks like it would work with your query:
Company:
- "[[Company ABC]]"
But this wouldn’t:
Company: [[Company ABC]]
