Welcome @laceyg,
HubSpot can be set to auto-create companies (based on website URL). Sometimes this is helpful. Sometimes, not so much.
- see Automatically create and associate companies with contacts
The thing is, HubSpot Companies are uber-useful when trying to ‘associate’ / organize Contacts -- which have no other way of being associated with each other in the HubSpot CRM.
Hope that helps a little.
Over to you @jennysowyrda
