Companies Using EventsCalendar.co

For a Shopify app, the first question a seller should ask is whether an install means anything. I fetched every domain carrying EventsCalendar.co's script, removed the 134 that were locked, closed or dead, then opened 119 random live stores, looked for a calendar and asked the app's own data service what each calendar held. As of our October 2026 crawl that leaves 3,155 live domains, and we matched 1,482 to a company.

1. Growth trajectory

There's no trend to read yet. Our crawl began tracking EventsCalendar.co in August 2026, and the cleaned count has one point, October. The crawled set also changes every month as dead stores leave and new ones arrive, and our detection widens over time. Since August, 322 domains dropped the script and 76 of them still run it on another hostname. The cleaning mattered more than the churn: 106 of the 134 domains we removed were Shopify stores behind a password page, still loading the app for nobody.

"On Shopify an installed app runs on every page whether or not anyone placed it. For EventsCalendar.co that means about half the count is calendars a shopper can see." - Sophie Clarke, Product Marketing Manager at TechnologyChecker.io

Sales Signal: Too early to call a trend. Treat the list as an installed base and qualify each store by whether its calendar is live.

2. Is the calendar live?

Of 119 random live stores carrying the script, I found a placed calendar on 57: 15 on the homepage, 42 on an events or classes page. The rest may have one on a page I didn't try, but most look like installs that were never placed. Of the 57, 51 showed events or a connected feed and 6 were empty. 33 were on paid plans and 24 on the free plan, which allows one calendar and 10 events. 22 pulled events from a connected account, most often Google Calendar, then Eventbrite.

Sales Signal: A store with a placed, paid calendar runs events often enough to pay for it. That's the segment to sell event marketing, booking or POS tools to.

3. Customer profile

73.62% of matched companies have 1 to 10 employees and 19.94% have 11 to 50. Founding dates are recent: 45.51% from the 2010s and 20.22% since 2020. The bigger names run it on a store, not a corporate site: Chronicle Books, Rubie's and Stiiizy all load the script on their Shopify storefronts, and SHOPLINE, itself a commerce platform, runs the general embed on its marketing site. Critical Role, WeatherTech Raceway Laguna Seca and the Georgia Tech Alumni Association show the event-led end. inlight labs doesn't publish a customer list I could fetch, so every name here is confirmed by its own page, not the vendor.

Sales Signal: The buyer is the store owner or a one-person marketing team. Sell in Shopify terms: an app, a plan, a free trial.

4. Industry and geography

Retail leads at 14.22%, with Food and Beverage Services (5.32%), Retail Apparel and Fashion (4.77%) and Non-profit Organizations (3.67%) behind. The country split is the Shopify one: the US has 921 matched companies, more than the next ten countries combined, ahead of Canada (121), the UK (102) and Australia (68). Many brands also own several domains: 2,714 cleaned domains with a Shopify store ID belong to 2,231 stores. The biggest fleets are single brands: Jordan Belfort's store sits behind 12 domains, and the next largest fleets have 7 or 8.

Sales Signal: De-duplicate by store before outreach, or you'll email the same coffee roaster five times. Then segment by vertical: cafes and breweries run weekly events, apparel brands run occasional pop-ups.

5. Switching and exits

We have no switching table for EventsCalendar.co: nothing in this category showed a flow large enough to test. Exits are modest, 322 since August, and nearly a quarter of those (76) still run it on another hostname of the same domain. The more interesting signal is partnership: some stores connect an Eventbrite account and show its events in the calendar, so a store can use both and neither replaces the other.

"The installs we removed failed with the store, not the app: 114 of the 134 were password pages or closed shops." - Sophie Clarke, Product Marketing Manager at TechnologyChecker.io

Sales Signal: For a ticketing tool, stores already feeding Eventbrite into the calendar are warm: they sell tickets and want them on their own site.

6. Technology ecosystem

Across our 3,155 cleaned domains, Shopify runs on 88.72% and Instafeed on 21.97%, the usual small-store app stack. Webflow is the largest non-Shopify home at 8.34%; WordPress is only 2.0%, which is why this app and the WordPress plugin EventOn barely compete. Email marketing is well used: Mailchimp on 21.33%, Klaviyo on 15.85%.

Sales Signal: These stores already email customers. A pitch that ties events to the email list, such as event reminders or post-event offers, fits the stack they have.

7. Pricing and plan signals

The 37 Shopify App Store reviews with written text that we read mostly praise how easy it is to set up and use; the most common complaints are unanswered support requests and display limits. The plan data says more about who pays. The Shopify App Store listing shows a free plan and paid plans at $10, $25 and $50 a month, rated 4.6 from 43 reviews when I checked. In my sample, paid calendars outnumbered free ones 33 to 24 among those placed.

Sales Signal: Paying stores are the minority of installs but the majority of live calendars. Prioritise them.

Key takeaways

1. 3,155 live domains, 2nd of 57 in Event & Ticket Booking with an 11.68% share, almost all Shopify.
2. Roughly half of installs show a calendar: 57 of 119 in our sample.
3. We removed 134 domains, mostly password-locked Shopify stores, before counting.
4. Small, young retailers dominate: 73.62% have 1 to 10 staff.
5. Brands own several domains; 2,714 store-linked domains map to 2,231 stores.

Sales applications

Outreach template: "Your store lists events with EventsCalendar.co. [Product] turns those events into bookings and repeat visits, without leaving Shopify."

Targeting strategy: On TechnologyChecker.io, filter EventsCalendar.co sites to Shopify, then to Food and Beverage Services, Wellness and Fitness, and Retail. Check each store for a placed calendar before outreach.

Competitive angle: Sell against the free plan's 10-event limit, which busy stores outgrow.
