Attio, Capsule CRM, HubSpot CRM
AI agents and automation depth
Attio's Workflows, Sequences, and configurable AI agents for research and lead scoring go further than the AI enrichment and summary features Capsule CRM adds from its Growth tier up, or HubSpot's Enterprise-only predictive lead scoring.
Attio
Post-sale delivery tracking
Capsule CRM's project boards let a team manage the work that happens after a deal closes inside the same product, a capability not documented for Attio or the core HubSpot CRM.
Capsule CRM
One platform to grow into
HubSpot CRM sits on the same object model as HubSpot's paid Marketing, Sales, Service, and CMS Hubs, so a team can add advanced functionality later without migrating existing contact and deal data.

Frequently Asked Questions
Which CRM has the most generous free plan?
HubSpot CRM, whose free tier supports unlimited users with no time limit. Attio's free plan is capped at 3 seats and Capsule CRM's at 2 users and 250 contacts.
Which is best for AI-native sales automation?
Attio is the most automation-heavy of the three, offering configurable AI agents, natural-language search and record creation, automated Workflows, and outreach Sequences as core parts of the product.
Which is the simplest CRM to set up for a small business?
Capsule CRM is positioned specifically as a simpler alternative to platforms like Salesforce or HubSpot, with a straightforward pipeline and project-board setup a small team can start using within a day.
Can I upgrade from a free CRM into more advanced marketing or service tools without switching platforms?
HubSpot CRM is built for this: it shares the same underlying object model as HubSpot's paid Marketing, Sales, Service, and CMS Hubs, so contacts and deal history carry forward automatically when a team upgrades.
Which CRM offers project management after a deal closes?
Capsule CRM includes project boards for tracking delivery work once a sale is won, a feature not documented for Attio or HubSpot CRM's core product.
Which is most affordable to scale as a sales team grows?
It depends on usage: HubSpot CRM stays free for basic use regardless of team size, but its paid Hubs get expensive per seat; Attio and Capsule CRM both charge per seat once a team exceeds their free-tier caps.
