Integrations you already use

  • HubSpot – two-way sync
  • MS/Gmail inbox directly connected
  • MCP – control from your own chatbot
HubSpot
Contacts and deals, in sync both ways.
MS / Gmail inbox
Your inbox right in Heimster, sent as the agent.
MCP

Honestly compared

Others are
closed islands.

Legacy CRMs offer a CSV export and a few rigid interfaces at best. Heimster is built open: API, real webhooks and MCP – you keep control of your data.

The value

Built open,
included in the subscription.

What others sell as an enterprise extra for API access and integrations is part of the deal with Heimster.

Included in your plan
Elsewhere
