Streamlining Company Creation from Trade-Show Attendee Data in HubSpot

Hey everyone, I could use some help in a "real-world" application. I received a list of trade-show attendees that contains: First Last Company Name Company Address Company Phone Number I brought the CSV into Clay, enriched company to find URL, then checked HubSpot via Lookup to filter out "new" companies. When I created the Hubspot Company Objects, it created one per contact at each company (not what I wanted to do). I can't think of a way to only create one company (not one per contact) via Clay outside of first deduping my companies and working out of two tables. Does anyone have a way to handle this? It's a repetitive request I get from our marketing team so I'd love to stop deleting/merging duplicates 🙂
