HubSpot is the leading customer platform for marketing, sales, and service. With seven integrated hubs, you manage your entire customer journey in one place. Dun & Bradstreet is the world’s leading provider of validated business data, compliance information, and risk assessments for over 500 million companies worldwide.
The HubSpot Dun & Bradstreet integration connects your CRM with the most comprehensive business database on the planet. You enrich companies automatically with DUNS number, industry, revenue, employee count, and credit data. No more manual research, no outdated information, no duplicates.
From master data enrichment to compliance checks, this integration covers all the use cases that take your data quality to the next level.
Enrich companies with D&B data. As soon as a new company is created in HubSpot, the integration automatically adds all available D&B data. DUNS number, legal name, address, industry, revenue, employee count: all validated, standardized, and up to date.
Compliance data for risk management. KYC (Know Your Customer), AML (Anti-Money Laundering), and ESG scores are available directly in the company timeline. You identify risks before entering business relationships and meet regulatory requirements without additional effort.
Activate D&B monitoring. Every company with a DUNS number is automatically monitored. If something changes at a customer, such as a name change, relocation, or insolvency, you receive the information in real time directly in HubSpot.
Prospect with Criteria Search. You define criteria such as industry, company size, region, or revenue bracket. D&B delivers matching companies that you can add as new companies in HubSpot with a single click.
Eliminate duplicates. The DUNS number is a globally unique company identifier. The integration uses it to detect and merge duplicates. No more multiple records for the same customer.
Establish golden records. D&B becomes the external reference for your master data. You define which fields should come from D&B, and the integration keeps them permanently up to date. This is master data management without a dedicated project.
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.

Measurably improve data quality. 70% of CRM data becomes outdated within a year. With the D&B connection, your HubSpot stays permanently current. Companies with clean data achieve up to 30% higher revenue according to studies, because sales and marketing reach the right target audiences.
Meet compliance requirements without extra effort. KYC and AML checks are mandatory in many industries. Instead of external tools or manual research, the data is available directly in HubSpot. This saves time, reduces risk, and provides auditors with clean documentation.
Enable targeted expansion. Criteria Search identifies potential customers based on your criteria. You enter new markets systematically rather than by chance, with all relevant company data in your CRM from the start.
For: Marketing, Sales, Customer Success, Operations
Lead scoring based on real data. Instead of estimates, your scoring is based on validated information: company size, revenue, industry, financial strength. You prioritize the right leads and waste no time on companies that do not fit your ICP.
Personalization without research. Every company timeline immediately shows the relevant business data. Sales enters conversations informed, marketing segments by real criteria, and customer success recognizes early when something changes at a customer.
Account based marketing with substance. ABM campaigns thrive on precise company data. With D&B enrichment, you know which companies fit your target audience and reach decision-makers with relevant messages rather than generic content.
Proactive customer management. D&B monitoring informs you about changes at existing customers. A name change, a new location, a credit rating shift: you respond before the customer reaches out or churns.
For: IT, Development, System Architects, Admins
All D&B data blocks available. MARINI accesses all data blocks via the D&B Direct+ API: Master Data, Sales & Marketing Intelligence, Compliance, Financial Risk Assessment, and Company Financials. You choose which data you need and map it to HubSpot properties.
Real-time enrichment without batch processing. New companies are enriched immediately, not at the next sync. Webhooks from HubSpot trigger the D&B query, and the data appears in your CRM within seconds.
Type-ahead and identity resolution. The integration supports company search directly during record creation: type the name, and D&B suggests matching companies. Identity resolution matches the most likely hits even with incomplete information.
No installation, no maintenance. The MARINI Integration Platform runs in the cloud. No plugin in HubSpot and no local software. OAuth authentication is all you need, and the connection is ready. Logs and monitoring show you what is being synchronized at any time.
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.
Through MARINI, all D&B data blocks are available: Master Data (DUNS, address, industry, employee count), Sales & Marketing Intelligence, Compliance data (UBO, Sanctions), Financial Risk Assessment, and Company Financials. You select which data you need and map it to the appropriate HubSpot properties.
As soon as a company is linked to a DUNS number, it is automatically added to D&B monitoring. If something changes in the D&B Data Cloud, such as a name change or credit rating update, the new data is pushed to HubSpot in real time. You do not need to trigger anything manually.
Yes, using D&B data requires a contract with Dun & Bradstreet. MARINI is a certified D&B partner and can assist with obtaining the right data blocks. The integration itself is then handled through the MARINI Integration Platform.
Absolutely. MARINI delivers D&B data not only to HubSpot but also to Salesforce, SAP, Microsoft Dynamics, and virtually any other CRM or ERP. If you have multiple systems in place, the data can be distributed centrally through MARINI.
The DUNS number is a globally unique company identifier. When a new company is created, the integration checks whether a record with this DUNS already exists. This prevents duplicate entries and keeps your CRM clean.
Yes. The MARINI Integration Platform is hosted exclusively in EU data centers that are ISO 27001 certified. Only company data is enriched, not personal data. Processing is fully GDPR and Swiss DPA compliant.
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.


With MARNI, we were able to successfully optimize our digital sales processes. We were particularly impressed by the flexibility and scalability of the platform, which helped us to implement our projects quickly and efficiently.
