Why the HubSpot Platform?
HubSpot is best understood using the flywheel visual diagram as opposed to a funnel - the flywheel better illustrates the customer's journey from stranger to promoter.
The platform helps your Customer Facing teams deliver a frictionless experience along the buyer's journey. Marketing, Sales and Service work together using the same tools in a common, shared database.
The buyer's journey and the HubSpot tools looks like this...we attract Strangers and by focusing on helping the person achieve their goals and solving their challenges, we succeed by adding New Customers that turn into Promoters for your organization.
And if you have other tools that you love and use - chances are good that these tools work with the HubSpot ecosystem.
