Unfurl dedupes companies by domain and contacts by normalized email, then files everything it could not fix: deals with no company, open deals with no amount, close dates already in the past. Ask your agent for the pipeline and the caveats come with the answer.
Two records for the same company double-count pipeline. A deal with no amount quietly undercounts it. Point an agent straight at the CRM and it repeats those mistakes with confidence.
Two commands, no credentials. Then connect HubSpot when you are ready.
