At its core, HubSpot is a CRM system, but it particularly excels in automation. You can use it to perform repetitive tasks and always have the most up-to-date data about the contacts and customers you are responsible for.
With HubSpot's lead scoring model, you can also set which contacts, companies, interactions, and properties best fit your organization. If a lead meets the criteria, your sales team will be immediately notified, so they can begin their follow-up.
