Kantos vs HubSpot

Looking for a HubSpot alternative?

HubSpot is a capable, mature platform with a large ecosystem. But for many growing businesses the reality is contact-based pricing that climbs as your database grows, and essential capabilities — custom objects, advanced automation, deeper API access — gated behind higher tiers. Kantos takes the opposite approach: a fully customizable data model, automation, and full API access on every paid plan, at transparent flat pricing, with AI integrated at the core.

Why teams choose Kantos

  • Unlimited custom objects and fields on every plan — model your real business, not just Contacts/Companies/Deals.
  • Full REST + MCP (Model Context Protocol) API access on all paid plans, so AI agents like Claude can operate your CRM directly.
  • Transparent flat pricing with no per-contact charges — your bill does not grow just because your database did.
  • Automation, custom data model, and data export available without an enterprise upgrade.

Where HubSpot wins

We'd rather be honest. HubSpot is the better fit if you need:

  • A large marketplace of integrations and certified solution partners.
  • Built-in marketing suite: CMS, landing pages, and a mature email/marketing hub.
  • Extensive documentation, community, and brand recognition.

Kantos vs HubSpot: FAQ

Is Kantos a good HubSpot alternative?

Kantos is a strong HubSpot alternative for growing businesses that need a fully customizable data model, automation, and full API access without enterprise-tier pricing — especially teams whose workflows do not fit the standard Contacts/Companies/Deals structure. If you primarily need an all-in-one marketing suite with a large partner ecosystem, HubSpot may suit you better.

How does Kantos pricing compare to HubSpot?

Kantos uses transparent flat plans (Free, then $19/mo and $49/mo) with no per-contact charges, so your price does not increase as your contact list grows. HubSpot uses contact- and seat-based pricing where costs scale with your database and tier.

Does Kantos have an API like HubSpot?

Yes. Kantos exposes a REST CRM API for objects, fields, records, automations, and media with API-key authentication, plus a Model Context Protocol (MCP) server with 60+ tools so AI agents can query and manage your CRM directly. API access is included on every paid plan.

Can I migrate my data from HubSpot to Kantos?

Yes. Kantos supports CSV/Excel import with field mapping and duplicate detection, and its custom data model lets you recreate your existing objects and fields. Reach the founding team via live chat or support@kantos.ai for migration help during early access.
