What LeadCascade does

Every row of your file becomes a HubSpot lead linked to its contact and company, with a result CSV, a link to each record in HubSpot and Undo for 30 days.

Who it is for: RevOps, sales ops and HubSpot consultants who move leads into HubSpot from another CRM or a spreadsheet and want each lead in the Leads workspace with its contact and company. The HubSpot account needs the Leads object (Sales Hub Professional or Enterprise).
