HubSpot

HubSpot has a genuinely free CRM with unlimited users, so most small businesses start there at no cost. The paid Starter tier is $20/seat/mo, billed annually, and adds higher limits and marketing tools. The jump to Professional is steep and also carries a mandatory one-time onboarding fee, so plan for that step before you commit.

Yes. HubSpot's free CRM is one of the most generous on the market, with unlimited free users, contact and deal management, a visual pipeline, and basic email tools. It is the most common starting point for US businesses moving off spreadsheets. The free plan supports up to Unlimited users. You only pay when you need higher limits or the marketing, sales, and service features in the paid tiers.

The paid Starter plan includes 1,000 (Starter). Additional marketing contacts are billed in blocks as your list grows, which is the main hidden cost to watch on HubSpot. Non-marketing contacts (records you do not actively email) do not count toward the marketing contact limit, so the cost tracks your active audience rather than your full database.

Yes. HubSpot includes Breeze, its native AI layer for content generation, lead scoring, and prospecting, available across paid tiers with some capabilities on the free plan. HubSpot also publishes an official MCP (Model Context Protocol) server in beta, so AI assistants and agents can connect to your CRM data directly rather than through a third-party connector.

HubSpot is an excellent starting point for US small businesses because the free CRM covers the basics with no cost and no seat limit. The caution is scaling: the move from Starter to Professional is several times the price and adds onboarding fees, so businesses that expect to grow into marketing automation should budget for that jump rather than being surprised by it.
