HubSpot CRM is the central data layer of HubSpot's customer platform, unifying contacts, companies, deals, and tickets across its Sales, Marketing, Service, Content, Operations, and Commerce Hubs. It is well known for a free starting tier and an emphasis on ease of use, which has made it especially popular with small and mid-sized businesses.
The platform combines pipeline management, email and meeting tracking, sequences, quoting, and reporting with a unified contact timeline. HubSpot has added AI capabilities under the Breeze brand, including content assistance, prospecting agents, and conversational tools that operate on CRM data.
HubSpot connects to ERP and accounting systems such as NetSuite, QuickBooks, and Microsoft Dynamics through its App Marketplace, native and third-party connectors, and a well-documented REST API. These integrations typically sync companies, deals, orders, and invoices so revenue teams and finance share consistent customer records.
