Companies Using Microsoft Dynamics 365

I've spent more than a decade building web crawlers and working with technographic data. This analysis covers 12,846 domains running Microsoft Dynamics 365 as of our July 2026 crawl, of which we matched 10,901 to company records. That 84.5% enrichment rate is more than double what we normally achieve, and it's the first clue about what this dataset is.

What we actually detect

Most technologies reach us through a script tag. Dynamics 365 reaches us through DNS: the domain publishes a d365mktkey TXT record, which Microsoft requires to authenticate a sending domain for Dynamics 365 Customer Insights, previously called Dynamics 365 Marketing. Two things follow. The signal is deterministic, and our numbers show it: active domains average 3.30 detections across 3.30 scans, a perfect hit rate, where a consent-gated ad pixel we studied recently managed 1.23 detections per 2.67 scans. And DNS records sit on apex corporate domains, which is why 57 of our top 60 detections are bare company domains. So this is not the full Dynamics 365 licence base, which is far larger. It's the subset running the marketing module on an authenticated domain.

"A 3.30 out of 3.30 detection rate told me this wasn't a pixel before I ever looked at the ruleset. Deterministic signals produce boring, beautiful data." - Mehmet Suleyman, Founder at TechnologyChecker.io

Sales Signal: Every domain in this list has completed a DNS change to send marketing email through Dynamics. That's a committed, budgeted deployment, not a trial. Treat the list as qualified rather than speculative, and expect a marketing operations owner rather than a general IT contact.

Customer profile

This is an enterprise and upper mid-market base. 51-200 employees is the largest band at 24.86%, 61.9% employ more than 50 people, and 16.43% exceed a thousand. Micro-businesses are only 14.09%. The age data is more striking: Pre-1960 is the biggest cohort at 21.06% and roughly 57% were founded before 2000, though Pre-1960 is an open-ended bucket spanning a century. Legal structure sharpens it: 20.71% are public companies and 21.2% are nonprofits, educational institutions or government agencies. Microsoft's published case studies overlap our detections in places, including Siemens and Zurich, though both of those stories describe different modules than the one we detect. Siemens also shows departmental deployment: our hit is on its mobility division domain.

Sales Signal: These buyers already run Microsoft licensing and have procurement cycles measured in quarters. The 21.2% public sector slice needs framework agreements and accessibility compliance, so lead with references from the same sector rather than with feature comparisons.

Industry and geographic concentration

IT Services and IT Consulting leads at 12.26%, or 14.77% once you fold in LinkedIn's older label for the same sector. That's the partner channel, not end demand. Microsoft stated in 2019 that 95% of its commercial revenue flows through its partner ecosystem, and implementation partners deploy Dynamics on their own sites first. Strip them out and Higher Education at 4.65% becomes the leading genuine vertical, with Penn State, Arizona State, NYU, Indiana and the University of Michigan all present.

Geography departs hardest from our usual pattern. The United States is just 21.81%. The United Kingdom (9.52%) and Germany (9.11%) are effectively tied, Europe totals close to 49.5%, and the Nordics contribute 9.39% from about 28 million people. London is the top city, with Stockholm and Oslo both ahead of New York. The reason is historical: Microsoft acquired the Danish vendor Navision in 2002 and rebranded it Dynamics NAV in 2005, seeding a partner network across the Nordics and DACH that still shapes the base.

Sales Signal: If you sell Dynamics services, the underserved geography is not Europe, it's everywhere else. Filter for the 21.81% US base and Australia's 6.94%, where partner density is thinner relative to install base. For European targets, expect an incumbent partner already in place and sell displacement rather than greenfield.

Migration patterns

Movement is small and one-directional. Since March 2026, 12 domains dropped Salesforce while keeping Dynamics 365, against one the other way, with 6 of the 12 in the last thirty days. Single domains arrived from Bitrix24 and Zoho. Seventeen events is not a trend and I won't dress it up as one. The more useful figure is the churn floor: only 46 domains dropped the signal entirely, about 0.36%. Discount even that, because DNS records routinely outlive the products that required them. We covered the general pattern in why SaaS companies switch CRMs.

"Twelve companies left Salesforce for Dynamics and one went back. That's a signal worth watching, not a headline worth printing." - Mehmet Suleyman, Founder at TechnologyChecker.io

Sales Signal: The 6 domains that dropped Salesforce in the last month are the highest-intent accounts on this page, because they're mid-migration and buying services now. On the retention side, a 0.36% churn floor means displacement campaigns against Dynamics incumbents will be slow and expensive.

Technology ecosystem

Google Tag Manager at 76.82% and Google Analytics at 67.25% are the baseline. The interesting layers sit below. Consent management is heavy and distinctly European: Cookiebot 13.66%, Cookie Control 14.36%, Usercentrics 5.2% and Cookie Information 1.52%, which are Danish, British, German and Danish. On the CMS side Drupal reaches 8.4% across both variants and TYPO3 hits 4.08%, roughly twenty times its global share and almost entirely German-speaking. ERP co-occurrence is nearly nil, ServiceNow at 2.12% and Infor at 0.24%, exactly what you'd expect when the signal only sees the marketing module. HubSpot appears on 8.65% and WordPress on 40.43%.

Sales Signal: That 8.65% HubSpot overlap is the clearest upsell and consolidation target on the page: those organisations are paying for two marketing stacks. The 40.43% on WordPress are candidates for integration work, since WordPress and Dynamics forms rarely share data cleanly without help.

Third-party review signals

We couldn't collect structured G2 review text for this profile, so treat this as cited rather than measured. Public ratings diverge informatively: G2 shows Dynamics 365 Sales at 3.8 out of 5 across 1,622 reviews, while Gartner Peer Insights rates Dynamics 365 Customer Service 4.5 from 671 ratings and Customer Insights 4.2 from 328. Gartner's panel skews to verified enterprise buyers, G2's to mid-market, so the gap fits a product that rewards implementation investment. One detail corroborates us: G2 reports 39.4% of its Dynamics 365 Sales reviews come from mid-market firms, and our size data puts 37.64% of detected companies in the 51-500 range.

Sales Signal: The enterprise-versus-mid-market ratings gap tells you where deals go wrong. Mid-market buyers who expect self-serve setup are the churn risk, so implementation scoping is the thing to sell alongside licences.

Key takeaways

1. The 1.97% share and #4 rank understate the product. We measure a DNS record only marketing-module users create, so this is a floor, not a measure.
2. The base is old, large and institutional. 61.9% above 50 staff, 57% founded before 2000, 21.2% public or social sector.
3. Europe is the centre of gravity at roughly 49.5% against 21.81% for the US, traceable to the 2002 Navision deal.
4. Five independent signals agree on that geography: country, city, consent vendor, CMS and legal entity type.
5. The moat is switching cost, with a 0.36% churn floor and a 12:1 inbound ratio against Salesforce.
6. The vulnerability is the partner channel: 14.77% of the base is IT consultancies, so our footprint partly measures Microsoft's resellers.

Sales applications

Outreach angle: reference the overlap. "I see you're running both Dynamics 365 marketing and HubSpot" opens a consolidation conversation with the 8.65% carrying both, and it's verifiable from public DNS.

Targeting strategy: on TechnologyChecker.io, filter to Germany, the Nordics and the Netherlands, then to 51-500 employees, where partner ecosystems are densest and reference selling works. Invert the geography filter for under-served US and Australian accounts.

Competitive angle: the 6 domains that dropped Salesforce in the last thirty days are actively re-platforming, so they're open to implementation and data-migration vendors now.

All of this comes from our own crawl rather than a vendor feed: 12,846 detected domains and 10,901 enriched companies, across monthly coverage of 29.9M active domains at TechnologyChecker.io. Compare it against our Salesforce market share analysis.
