Visit website What is it?
HubSpot is a customer database (a CRM) with marketing, sales and support tools built on top. Its AI layer, called Breeze, includes agents that qualify leads, answer customer questions, draft blog posts and clean up your contact records.
Start with the free CRM to track contacts, deals and emails in one place. As you grow, add the marketing or sales hub and let the Breeze agents take over the repetitive work. HubSpot also publishes an official connection for Claude, so you can ask about your pipeline or update records from chat.
The free plan is excellent but the paid hubs add up fast, and the marketing automation is geared to B2B and services rather than online stores.
Who it's for
Service businesses, agencies and B2B teams that need contacts, deals and marketing in one system.
Best for
- Tracking leads and deals
- B2B email marketing
- Chatbots that answer customers
- Keeping contact data clean
Why it made the list
The best-known free CRM, now with AI agents that are practical rather than decorative.
