Would you like to have consistent and accurate customer data in HubSpot and MS Dynamics 365 Sales at all times without any IT projects? That’s exactly what MARINI is for.
With MARINI, the integration of HubSpot and MS Dynamics 365 Sales is ready to use in just a few days and grows flexibly with your requirements.
And the best part: we handle the integration for you. Our experts set up your HubSpot MS Dynamics 365 Sales interface on your behalf or together with your team.
Important note: The video shows the integration of HubSpot with SAP C4C. Of course, connecting to HubSpot with MS Dynamics 365 Sales and many other systems is also possible.






















HubSpot is the customer platform for marketing, service, and operations. Dynamics 365 Sales is Microsoft’s CRM with native Office 365 integration and AI-powered insights. Both systems excel on their own, but struggle when they operate in isolation.
The HubSpot Dynamics 365 Sales integration connects marketing automation with your sales pipeline. Qualified leads flow into your CRM, sales status flows back to marketing. The result: a seamless process from first click to closed deal, without manual handoffs and without data silos.
This integration is not a one-way street. You decide which data flows in which direction and which processes get automated.
Sync leads bidirectionally. Marketing-qualified leads from HubSpot are automatically created as leads in Dynamics 365 Sales. Complete with scoring, activity history, and campaign attribution. Sales instantly sees where the lead came from and how engaged they are.
Align contacts and companies with accounts. HubSpot companies become Dynamics accounts, HubSpot contacts become Dynamics contacts. Bidirectional, in real time, with duplicate detection. One customer view for marketing and sales.
Surface marketing activities in your CRM. Email opens, clicks, form submissions, and website visits appear directly in the Dynamics record. Sales knows what the prospect has been engaging with before picking up the phone.
Push opportunity status back to marketing. When an opportunity in Dynamics is won or lost, it automatically triggers workflows in HubSpot. Post-sale onboarding, customer surveys, or reactivation campaigns start without manual intervention.
Synchronize products and pricing. Products and price lists from Dynamics 365 Sales are available in HubSpot. Quotes are calculated correctly without anyone manually reconciling prices.
Build closed-loop reporting. Which campaign contributed to which deal? With this integration, attribution data flows back, and marketing can finally prove the revenue it generated.
Beyond these scenarios, many additional use cases are possible. The integration grows with your requirements.
The use cases on this page are not theoretical, but implementing them requires experience. You can set up integration and data management yourself through MARINI’s no-code interface, or have our team configure it for you. For implementation in your systems, we work collaboratively with you and your service providers. If you don’t yet have a suitable service provider, we’re happy to recommend an appropriate partner from our network.

Marketing ROI becomes measurable. When revenue data from Dynamics is linked with campaign data from HubSpot, you finally see which marketing investments pay off. Budget decisions are based on facts, not gut feelings.
Sales cycles get shorter. Leads arrive qualified and with context. Less research, faster first conversations, shorter time to close. This directly impacts revenue.
Your system landscape stays flexible. You do not have to choose between HubSpot and Dynamics. Leverage the strengths of both platforms without creating data silos. The integration is the bridge, not the compromise.
For: Marketing, Sales, Customer Success, Operations
Marketing sees what happens to leads. No more black box after the handoff to sales. The status of every opportunity is visible in HubSpot. Marketing can optimize campaigns because it knows which leads actually convert.
Sales works with full context. Before the sales rep calls, they see all marketing touchpoints in the Dynamics record. Which emails were opened? Which pages visited? The conversation starts at a different level.
Customer success spots upselling opportunities. When an existing customer suddenly starts consuming marketing content again, that is a signal. The integration makes these signals visible so CSM can act proactively.
Operations saves hours of manual work. No Excel exports, no copy-paste routines, no data reconciliation at month-end. The systems keep themselves in sync.
For: IT, Development, System Architects, Admins
Modern APIs on both sides. HubSpot offers a comprehensive REST API with OAuth 2.0 and webhooks. Dynamics 365 Sales uses OData v4 and also supports event-based synchronization. MARINI connects both through a central platform.
Flexible mapping for standard and custom objects. Contacts, companies, deals on one side. Leads, contacts, accounts, opportunities on the other. The field names differ, but mapping is transparently configurable. Custom objects and custom entities are fully supported.
Bidirectional real-time synchronization. Changes propagate in both directions as soon as they occur. Conflict rules can be defined so it is clear which system wins when data conflicts arise.
No installation in your systems. MARINI runs as a cloud service with EU hosting. Nothing needs to be installed in HubSpot or Dynamics. Logs, monitoring, and alerts are accessible through a central dashboard.
Business-critical data deserves maximum reliability. At MARINI, security isn’t an add-on—it’s our lived standard. Our security architecture at a glance:
This keeps your central data infrastructure stable, protected, and scalable at all times. Together, we’ll find the right integration and tailor it precisely to your requirements.
The integration supports all relevant standard objects: Contacts, companies, and deals from HubSpot sync with leads, contacts, accounts, and opportunities in Dynamics 365 Sales. Additionally, products, quotes, activities, and custom objects can be included.
You have the choice. The integration can be configured unidirectionally or bidirectionally, depending on your use case. For most scenarios, we recommend bidirectional sync with clear rules defining which system is authoritative for which fields.
Yes, fully. HubSpot custom objects and Dynamics 365 custom entities are treated like standard objects. You can include them in the synchronization and define your own mapping rules.
No. MARINI is independent of HubSpot pricing tiers. You save the additional cost of Operations Hub while gaining more flexibility in mapping and transformations.
That depends on the scope. A basic integration with contacts, companies, and deals can go live within a few days. More complex scenarios with custom objects, multiple sync directions, and validation rules require more time accordingly.
Yes. MARINI hosts exclusively in the EU, is ISO 27001 certified, and meets the requirements of GDPR and Swiss revDSG. Personal data never leaves the European jurisdiction.
With MARINI, we use a reliable interface between our existing ERP system and HubSpot. The data exchange works seamlessly and delivers tangible added value in our day-to-day operations. We are particularly impressed by the platform’s clear structure as well as the direct and straightforward communication with the support team.


The integration of our marketing automation (Evalanche) and Salesforce via MARINI takes our data quality to a new level and provides the basis for successful account-based marketing.
