Dan, you can add an enrichment and use the "Tech Stack" waterfall to learn about the products/services a company may have.
The "Tech Stack" integrations (BuiltWith/PredictLeads, and their waterfall) don't have any built-in ways to exclude. So you'd need to get their response back, and then decide what to do with it.
For example, after getting the stacak list, you could set up a "Intercom user?" formula column to flag those that have it, e.g.
{{Tech Stack}}?.includes("Intercom")
You could then use that true/false result to control logic elsewhere in your table. Does that help?
