Fuzzy Matching Techniques for Comparing CRM and TAL Company Data

Hi. I'm trying to make a fuzzy match with Clay. In one table I have all the companies in my CRM ("HubSpot"). I have a few identifiers like the company name, email domain and sometimes the linkedin company page. In another table I have a list of companies in my TAL. ("TAL"). I want to check which companies from my table "HubSpot" are in the table "TAL". I've been trying to use different AI prompts to make a fuzzy match but can't make it work. It always hallucinates. Is there a known way to make fuzzy matches between tables?
