Companies Using Customily

I've spent years building crawlers, and a page like this usually goes wrong in one of two ways. It counts domains as if they were customers, or it names famous brands without asking who runs their store. Customily needs both questions answered. Our October 2026 total puts it on 1,213 domains; 1,167 were live in our crawl in mid-October, and we matched 368 of them to a company. I loaded all 50 rows of the company list in a browser, plus a random sample of 100 live domains, before writing a word.

Who runs the famous shops

The biggest names on the list are licensed merch stores, and most of them share an operator. The HBO, Paramount, Netflix, Minecraft and FOX Square shops all name Snow Commerce as the seller in their footers, and the BBC Shop says Snow runs it under licence from BBC Studios. Counting the Snow-specific support and consent set-ups these stores load, plus three addresses I checked by hand, at least 55 live Customily domains (4.71%) belong to Snow, across 26 brand stores. Snow's own site leads with personalised ecommerce and announces on-demand, personalised Peanuts jerseys, so Customily sits close to the middle of what it sells.

Sales signal: one operator decides for all 26 brand stores. Mattel Creations is different: it loads no Snow set-up, and Mattel's own name is on its copyright line.

Growth trajectory

Our monthly totals read 902 domains in June, 1,203 in July, 1,227 in August, 1,176 in September and 1,213 in October. The June to July step was ours: the set of domains we crawl turns over every month as dead sites leave and new ones arrive, and our detection signals widen over time. So I read July to October as flat. Under the flat line there's movement. 500 domains dropped Customily on at least one hostname since we started tracking it on 16 March 2026, and 44 of those still ran it on another hostname when we re-checked.

The count is also smaller than it looks. In our sample, 31 of 100 domains forwarded to another web address, and 20 of those landed on a store that's already in the count. Grouping domains that load another listed store's theme files leaves at most 999 stores. One store alone has 16 domains. The same sample shows how many are trading: 94 loaded Customily's code, 6 of those behind a password page, and 2 weren't trading at all, one closed store and one domain that no longer resolves. All of them stay in the count: a password page still loads Customily, and a failed fetch doesn't remove a domain.

"The line is flat at about 1,200 domains, but one domain in five we sampled was a second address for a store already on the list. Plan around 900 to 1,000 stores, not 1,213." - Mehmet Suleyman, CEO & Co-founder at TechnologyChecker.io

Sales signal: the base is steady rather than growing, so pipeline has to come from stores already running Customily.

Customer profile

58.21% of matched companies with a known size have 1 to 10 employees and 30.26% have 11 to 50, so 88.47% have 50 staff or fewer. That's a bigger-company base than Shopify's as a whole, where our Shopify market analysis puts 82.7% at 1 to 10. The base is older than its rivals' too: only 12.44% were founded in the 2020s, against 22.32% to 28.72% on the Zakeke, Kickflip and Teeinblue profiles, and 7.18% before 1960. The stores sell things people give. GLDN sells personalised fine jewellery, Fire & Pine engraved wood maps and Christmas by Krebs personalised ornaments.

Sales signal: these are owner-run shops where every order carries a name or a photo. They buy what cuts minutes per order, such as automated print files and fulfilment links. Pitch hours saved per hundred orders.

Industry and geography

Retail leads at 20.6%, then Retail Apparel and Fashion (11.63%), Manufacturing (7.31%) and Retail Luxury Goods and Jewelry (4.98%). Printing Services (3.99%) is small but telling, because print shops and engravers are exactly who needs one file per order. Geography is narrow. The United States holds 224 of the 368 matched companies, and with the United Kingdom (40), Australia (13) and Canada (13) the four English-speaking markets reach 78.8%. Spain (9), France (7) and the Netherlands (6) lead continental Europe, even though the app runs in eleven languages, per its Shopify listing.

Sales signal: work the US list first. In Europe, Club Brugge and ADO Den Haag show the use case in club shops, and Spain's Friking in printed T-shirts.

Switching and overlap

Our switching tests publish no rows for Customily, because too few domains move between it and any rival. Of 76 domains ever seen with both Customily and Teeinblue, 45 still run both; for Zakeke it's 37 of 54. Stores that try a second personaliser mostly keep both. The biggest overlap is Printful, on 192 domains today of 247 ever seen with both, and it isn't a rival: Customily's Shopify listing names Printful, Printify and Gelato among its print-on-demand integrations.

"Nobody is replacing Customily with a rival in numbers we can see. The Printful overlap is the real pattern: one app designs the order and the other prints it." - Mehmet Suleyman, CEO & Co-founder at TechnologyChecker.io

Sales signal: the 192 Customily-plus-Printful domains are a ready list for a print-on-demand provider or a fulfilment add-on. Stores paying for two personalisers, 45 with Teeinblue and 37 with Zakeke, are consolidation prospects.

Technology ecosystem

Across the 1,167 live domains, Shopify runs on 94.77% and BigCommerce on 4.8%. On BigCommerce, Customily loads its general script plus one written for that platform, and a few stores get a file named after them. Klaviyo's email tool is on 40.1%, and the leading review apps are Judge.me (26.14%) and Loox (9.94%). Google Analytics is on 64.35%. Gelato, another print partner, runs on 40 Customily domains.

Sales signal: many of these stores already use Klaviyo for email (40.1%) and a quarter use Judge.me for reviews, so a new tool has to work with both from day one. Consent tools are thin: Ketch leads at 4.28%, and most of its installs here are Snow's stores, loading Ketch under Snow's own set-up.

Review signals

Customily's Shopify App Store listing showed 4.9 stars from 276 reviews on 15 October 2026, with 252 five-star and 12 one-star ratings. Teeinblue's showed 4.9 from 380. Shopify's review summary says support is consistently praised. Ratings that high tell you onboarding works; they don't tell you who stays. Our churn number is the better check, and a flat total beside 500 drops since March means new installs roughly match departures.

Sales signal: a rival has to match Customily's onboarding as well as its price. The per-item fee, $1 for each of the first 100 items sold falling to $0.10 at volume, is where high-volume stores feel the cost.

Key takeaways

• About 1,200 domains, flat since July 2026, and fewer stores than domains.
• At least 55 domains (4.71%) are Snow Commerce's licensed shops: one buyer behind 26 brand stores.
• 88.47% of matched companies have 50 staff or fewer, and 78.8% are in four English-speaking countries.
• 94.77% Shopify, with Printful on 192 domains as a print partner rather than a rival.
• No measurable switching to Teeinblue or Zakeke.

Sales applications
