Companies Using Zendesk Chat

I'm Elif, CMO at TechnologyChecker.io. For this refresh I worked from our October 2026 crawl: 18,631 live domains still running the legacy Zendesk Chat widget, with 11,532 of them matched to LinkedIn company profiles, a 61.9% match rate. One thing to settle first: this profile counts the Zopim-era widget only, the script that loads from v2.zopim.com. Zendesk's current messaging widget is a different product with a different script, and our Zendesk profile counts it separately. So this is a list of sites that haven't moved yet.

1. A widget on a retirement clock

Zendesk bought Zopim, a Singapore startup, in a deal worth up to $29.8 million (TechCrunch, April 2014). The widget became Zendesk Chat, and in August 2026 Zendesk set its end date: Chat retires on 31 January 2028 for messaging-eligible Chat + Support and Suite customers. Zendesk's own notice says Chat hasn't received feature enhancements since 2020.

Our series runs 16,407 domains in June 2026, 18,249 in July, 18,435 in August, 18,640 in September and 18,631 in October. The June-to-July step comes from our side, both the set of domains we crawl, which turns over every month as dead sites drop out and new ones are added, and the signals we detect with. Since July the line has been flat. Meanwhile 3,328 domains have dropped the widget since 16 March 2026.

"Eighteen thousand sites are still running a chat widget that stopped getting new features in 2020. That's not a market. It's a migration queue with a published deadline." - Elif Arslan, CMO at TechnologyChecker.io

Sales Signal: Every one of these 18,631 domains is a site that will have to change its chat setup if it's on a Chat + Support or Suite plan. For a seller the question is timing: the deadline is 31 January 2028, and each of these teams will choose between Zendesk messaging and something else before then.

2. Customer profile: small and established

56.86% of matched companies have 1-10 employees and 28.21% have 11-50, so 85.07% employ 50 or fewer. Only 77 have more than 1,000 staff. The age data is the clearest signal on the page: 42.41% were founded in the 2010s and 27.98% in the 2000s, but only 1.22% in the 2020s. On our Intercom profile the 2020s share is 30.64%. Companies founded after Zendesk stopped developing Chat almost never installed it.

The larger names we could verify on their live sites are institutions and established businesses: Miami Dade College on mdc.edu, ComEd on its hourly pricing site, Partners In Health on its legacy-giving site, and Grote Industries on its online store.

Sales Signal: These are owner-run or small-team businesses with a widget that has run unchanged for years. A pitch that makes the switch painless, with migration help and a familiar inbox, will land better than a feature list.

3. Industry and geographic concentration

Retail leads at 8.2%, then IT Services (5.83%), Advertising Services (3.48%) and Real Estate (3.43%). Travel (2.79%) and Hospitality (2.11%) both make the top ten, and Software Development has only 3.02%. That is the opposite of Intercom's software-heavy base.

The geography is flat. The United States leads with 2,089 matched companies, but the UK (1,143), Brazil (1,038) and India (927) are close behind, and Spain (613) is fifth. Brazil, Mexico and Colombia together hold 1,627.

Sales Signal: A Spanish- and Portuguese-language campaign reaches a large share of this base. Retail, travel and hospitality accounts care about pre-sale questions, so lead with conversion, not ticket deflection.

4. Where legacy Chat sites go

No switching flow passes our tests, so this page has no migration table. The overlap numbers are still worth reading. Since March, 115 domains dropped the legacy widget and now show Zendesk's current widget, but 95 went the other way, and 459 of the 720 domains that have ever had both still run both. That looks like sites running old and new side by side, not a finished move.

Outside Zendesk the numbers are small. 35 domains dropped Zendesk Chat and now run Tawk.to, against 15 the other way, and 190 of the 275 that have ever had both still do. HubSpot Chat (19 out, 12 in), LiveChat (17 out, 8 in) and Tidio (9 out, none in) are smaller still. Intercom barely registers: 4 out and 2 in, with 34 domains ever running both.

"The migration Zendesk is asking for has barely started on the open web. Most sites that have Zendesk's new widget kept the old one running beside it." - Elif Arslan, CMO at TechnologyChecker.io

Sales Signal: The decision is still open for most of this list. Competitors have a window before January 2028; Zendesk's own team has the advantage of an existing contract and a built-in path.

5. Technology ecosystem

Across the 18,470 clean live domains, WordPress runs on 35.86%, Elementor on 5.19% and Joomla on 2.4%. Google Analytics (76.73%) and Google Tag Manager (69.23%) are the measurement pair. Commerce appears on a minority: WooCommerce 8.89%, Magento 4.44%, PrestaShop 3.13% and Shopify 2.8%. Only 2.48% also run Zendesk's current support widget.

Sales Signal: A WordPress plugin or a no-code install is the shortest path into this base. For commerce-focused chat tools, the WooCommerce and Magento accounts are the obvious first filter.

6. G2 review signals

The G2 summary on this page covers Zendesk for Customer Service as a whole, not the legacy Chat widget, so read it as sentiment about the platform these customers would migrate inside. Ease of use leads the praise with 515 mentions, and the unified platform follows with 389. The complaints are about fit: missing features (210 mentions), limited features for smaller teams (177) and a steep learning curve (169).

That last pair matters here, because 85.07% of this base employs 50 people or fewer. The teams that complain about setup effort are the teams that make up this list.

Sales Signal: Lead with setup time. A small retailer facing a forced move to Zendesk Suite is a good prospect for a simpler chat tool that installs in an afternoon.

Key takeaways

• 18,631 live domains still run the legacy Zopim widget; Zendesk's current widget is counted on the Zendesk profile.
• Zendesk Chat retires on 31 January 2028 for Chat + Support and Suite customers.
• 85.07% of matched companies have 50 or fewer staff, and only 1.22% were founded in the 2020s.
• The base is spread across the US, UK, Brazil, India and Spain, with 1,627 companies in Brazil, Mexico and Colombia.
• No clean switching flow yet: most sites with both Zendesk widgets still run both.

Sales applications

Outreach template: "Hi [Name], [Company] still runs Zendesk's legacy Chat widget on [detection URL]. Zendesk retires Chat on 31 January 2028 for Suite and Chat + Support plans. We help small teams [your migration outcome]. Worth a short call?"

Targeting strategy: On TechnologyChecker.io, filter Zendesk Chat + Retail, Travel or Hospitality + 1-50 employees, then split by language: English for the US and UK, Portuguese for Brazil, Spanish for Mexico, Colombia and Spain.

Competitive angle: Position against the forced move, not against Zendesk itself. Accounts already running both Zendesk widgets are mid-migration and probably committed; accounts with only the legacy widget are the open ones.
