Companies Using Adobe Marketo Engage

Marketo occupies an unusual position in our data. It ranks 13th in Marketing Automation with 13,604 domains and a 1.02% share as of our October 2026 crawl, behind tools most enterprise marketers never evaluate: push-notification widgets and site-builder add-ons that each sit on tens of thousands of small sites. Rank in this category measures how many websites a product touches, not the weight of the buyers behind it. Read Marketo by the shape of its 6,690 matched companies instead and a different platform appears. Adobe saw that too: it agreed to buy Marketo from Vista Equity Partners for $4.75 billion in September 2018 and completed the deal on 31 October 2018.

Growth trajectory

The current crawl reads 10,452 domains in June 2026, 12,820 in July and 13,604 in October. The June to July step reflects changes on our side, the domains we cover and the signals we detect Marketo with, rather than a wave of new contracts, because the set of domains we crawl turns over every month as dead sites drop out and new ones are found. From July the line rises by a few hundred domains a month. What's new on this page is the exit count: 5,196 domains have dropped Marketo since we began tracking exits on 16 March 2026. The base churns at the edges while the total holds.

"Marketo's domain count barely registers against HubSpot's, and that's the wrong comparison. Look at who is behind the domains and it's the enterprise B2B list, with a churn rate you can now actually see." - Elif Arslan, CMO & Co-founder at TechnologyChecker.io

Sales Signal: This is a mature, slowly turning base, not a growth market. The opportunity is the 5,196 exits and the accounts deciding whether to renew, not new adopters.

Customer profile

Company size is where Marketo separates from the category. Matched companies spread evenly across the three smallest bands (21.39% at 1 to 10 employees, 22.78% at 11 to 50, 22.08% at 51 to 200), and 14.54% employ more than 1,000 people: 931 companies, 224 of them above 10,000. Age points the same way. Only 4.88% were founded in the 2020s, while 11.84% predate 1960, including U.S. Bank, Chevron and IBM.

The detection host shows who owns the programme. 22 of the 50 largest companies on our list run Marketo on a subdomain rather than the main site: J.P. Morgan on its private bank, Synopsys on its newsroom, Orange Business on its blog. Others, such as IBM, Cisco, Chevron and U.S. Bank, run it across the main domain. Kaiser Permanente is on both lists that matter: our crawl finds Munchkin on kp.org, and CNBC named it as a Marketo customer when the Adobe deal was announced.

Sales Signal: The subdomain names the budget holder. A newsroom or blog host points to a communications team; a main-domain install usually means central demand generation.

Industry and geographic concentration

Software Development is the sharpest single finding: 19.04% of matched companies, 1,160 of them. Add IT Services and IT Consulting (7.2%) and Computer and Network Security (1.94%) and more than a quarter of the base sells technology to other businesses. Financial Services follows at 5.5%. The buyer is usually a demand generation team with a long sales cycle, a named account list and a sales organisation that expects marketing to source pipeline.

Geographically the United States holds 4,162 of the 6,690 matched companies, and the UK (466) and Australia (361) follow. The result worth noting is Japan in fourth place with 261, ahead of Canada and every European market.

Sales Signal: Japan is the outlier market. A Marketo agency or integration partner with Japanese capability has 261 matched companies to work through, more than Germany (102) and France (101) combined.

Where accounts move

Our exit tracking for Marketo opens in March 2026, so these are recent movements, and none of them passes our switching tests. Of the 5,196 domains that dropped Marketo since then, 325 now run HubSpot and 147 run Salesforce Marketing Cloud Account Engagement. But 1,937 of the 2,498 domains ever seen with Marketo and HubSpot still run both, and 912 of 1,156 for Account Engagement, and the traffic runs both ways: 112 domains that dropped HubSpot now run Marketo, as do 45 that dropped Account Engagement.

A dropped Munchkin on one property is not a cancelled contract. Most of these sites kept both tools, which is why this page shows no migration table.

"Marketo shares its biggest accounts with HubSpot and Salesforce far more often than it loses them to either. The overlap is the story, not the exits." - Elif Arslan, CMO & Co-founder at TechnologyChecker.io

Sales Signal: If you sell against Marketo, a site running HubSpot or Account Engagement alongside it is a consolidation conversation, not a rip-and-replace. If you sell Marketo services, the same overlap is the risk to watch: a second platform already in place is the cheapest way out.

Technology ecosystem

Google's tools surround Marketo: Google Tag Manager on 92.46% of live Marketo domains and Google Analytics on 89.3%. Adobe's own stack is a minority eight years after the acquisition, with Adobe Experience Platform Launch on 14.26%, the older Adobe DTM on 12.94% and Adobe Analytics on 9.29%. Where a CRM is detectable, Salesforce appears on 10.24% of Marketo domains against 0.54% for Microsoft Dynamics 365, about 19 to 1. Account-based tools are common: Qualified on 11.15% and Demandbase on 7.32%. All shares are of the 13,912 live Marketo domains in our clean set.

Sales Signal: Assume Salesforce and qualify for Dynamics. And the Adobe suite gap is open territory: on more than nine in ten Marketo domains we see no Adobe Analytics, which is pipeline for Adobe partners and for their competitors.

G2 review signals

Marketo's G2 reviews split cleanly. The most-cited strengths are day-to-day usability once programmes are built (192 mentions) and multi-channel automation (185). The leading complaint is the steep learning curve (176), followed by needing outside help to get started (135) and a dated interface (108); pricing draws 87 mentions. Our reading is that a platform which needs specialists to run tends to stay once the specialists are in place, and the coexistence numbers fit that: teams add HubSpot or Account Engagement beside Marketo far more often than they remove it.

Sales Signal: The 135 "needed outside help" mentions are the services market. Agencies and consultants selling Marketo administration have a stated need to answer, and the 931 companies above 1,000 staff are where it pays best.

Key takeaways

• 13,604 live domains, 13th in Marketing Automation, but 14.54% of matched companies have more than 1,000 staff.
• Software Development is 19.04% of the base; with IT services and security, more than a quarter.
• Japan is fourth, with 261 matched companies.
• No flow passes our switching tests: 5,196 domains dropped Marketo since March 2026, mostly at sites that also run a rival.
• HubSpot and Account Engagement mostly sit beside Marketo, not instead of it.

Sales applications

Outreach template: "Hi [Name], I saw [Company] runs Marketo on [subdomain] alongside [HubSpot/Account Engagement]. Most teams we see with both keep both. Is the split deliberate, or is one of them doing work the other could?"

Targeting strategy: On TechnologyChecker.io, filter Marketo domains to Software Development or Financial Services, 1,001+ employees, and sort by detection host so you reach the team that owns the programme.

Competitive angle: Use the coexistence rows rather than the exit count. A site running two marketing automation platforms is paying twice, and that overlap is a better opening than a churn story the data doesn't support.

How to read these numbers

Every count on this page comes from TechnologyChecker.io detecting Marketo's Munchkin tracking code on a live public website, so we count deployments rather than contracts. A Marketo customer that runs campaigns only through landing pages on a separate domain, or never adds Munchkin to its site, won't appear here. Counts are also not a like-for-like series over time: the set of domains we crawl turns over every month, with dead sites dropping out and newly found ones added, and our detection signals widen over time.
