Companies Using CartStack

CartStack looked like a simple brief: an abandoned-cart tool that isn't tied to Shopify. The first count said 3,120 live domains. Then I found that more than half of them run a different product. With those removed, our October 2026 crawl finds CartStack on 1,470 live domains, 925 matched to a company, 11th of 33 in Cart & Checkout with 1.91%.

One name, two products

CartStack once had a Brazilian edition, served from app.cartstack.com.br. Its website now shows PowerCart, and PowerCart's page says CartStack evolved into PowerCart, Performa.AI's product. Those stores still load the old script address, so our rule kept counting them. We removed 1,648 Brazilian-edition domains and 3 for-sale or gambling pages. What remains is the US company, a small Minneapolis team working on abandonment since 2013 according to its about page.

Sales Signal: if you bought a CartStack list anywhere before, check it for .br domains. Those are PowerCart customers, with a different vendor relationship.

What the chart can and can't show

The usage chart starts at October 2026, at 1,470, because our earlier monthly totals mixed in the Brazilian edition. Churn is the better signal. Of the 643 domains that dropped CartStack since 16 March 2026, 436 were Brazilian-edition sites. Only 207 US-product domains dropped it, and 29 of those still run it on another hostname.

"Half of what looked like CartStack was its former Brazilian edition, now PowerCart. Take that away and you're left with a hospitality tool: a third of its matched companies are hotels and resorts." - Elif Arslan, CMO & Co-founder at TechnologyChecker.io

Sales Signal: about 207 US-product departures in seven months, 14% of today's 1,470, and 29 of those still run it on another hostname. Watch for exits rather than assuming a locked-in base.

Domains are not accounts

The US script carries the customer's site in its file name, so we can count accounts: 1,281 domains belong to 847 accounts. 160 accounts cover two or more domains, 594 domains between them. Sandestin runs one account across 20 domains, and an account named after hornblower.com, which now forwards to City Experiences, covers 13.

Sales Signal: dedupe by account before you size a campaign. 1,470 domains are closer to 1,000 buyers.

A hospitality tool

Hospitality is 34.71% of matched companies, Real Estate 11.36% and Retail only 5.62%. Add travel and leisure and stays and trips reach 51.82%. The named users bear it out: Sonesta, Sandestin, Caribe Royale, Woodloch and Sunlife in Mauritius among hotels and resorts, Hawaii Life Vacations among rental managers, and City Experiences, Southern Airways Express and Tradewind Aviation among travel companies. Further down the list sit the Grand Hotel on Mackinac Island, Kingsmill Resort in Virginia, the Woodstock Inn in Vermont, Shutters on the Beach and Hotel Casa del Mar in Santa Monica, The Hotel Windsor in Melbourne, and museums such as The Broad and the Santa Barbara Museum of Natural History. CartStack prices hotels by room count on a separate pricing page, so this is a market it chose.

Sales Signal: for hotel-tech vendors, a CartStack install marks a property that already pays to win direct bookings. Booking engines, rate tools and guest messaging sit on the same budget line.

Older and a little larger

48.23% of matched companies with a known size have 1 to 10 employees, but 19.9% have more than 50. The founding years skew old: 43.39% before 2000 and only 8.68% in the 2020s. Boudin Bakery dates from 1849 and Sonesta from 1937. The United States holds 81.51% of matched companies, with Canada (36) a distant second.

Sales Signal: these are established businesses with marketing managers, not founders doing everything. Lead with reporting and proof of recovered revenue.

Rivals and overlaps

Our switching tests found nothing to chart. UpSellit (3,030 domains) and CareCart's Cartly are the closest tools in the category, and no more than one domain runs CartStack and UpSellit together. CartBot and GoKwik rank higher, but one is a Shopify cart upsell app and the other an Indian checkout. The real competition is the email platform a site already pays for: Mailchimp runs on 10.75% of CartStack domains, Klaviyo on 7.89% and Amazon SES on 7.76%.

"Nobody switches from CartStack to a lookalike. The decision is whether a dedicated recovery tool beats the email platform the site already has." - Elif Arslan, CMO & Co-founder at TechnologyChecker.io

Sales Signal: pitch against the email platform, not the rival app. For an email vendor, a CartStack site is a buyer who already values recovery.

The stack around it

Google Analytics runs on 97.01% of CartStack domains. WordPress is on 46.73% and Elementor on 7.28%, while Shopify is on 4.63%, WooCommerce on 4.22% and Magento on 3.67%. Hotel software shows in The Hotels Network (2.99%) and KeyData Dashboard (3.74%), and consent banners from CookieYes (5.71%) and OneTrust (5.37%) are common.

Sales Signal: these sites measure everything, so attribution proof gets a hearing. WordPress booking sites also need conversion help between the room page and the booking engine.

What it costs

CartStack's pricing page (checked 14 October 2026) starts Recover at $69 a month and shows $99 at 101 to 200 orders, with Retain adding $20. Hotels pay by rooms, from $199, and $399 at 101 to 200 rooms. There's no commission on recovered revenue, and a 14-day trial comes with a $1,000 recovery guarantee.

Sales Signal: flat pricing means the bill doesn't grow with success, so renewals turn on reported recovered revenue. Show a better number and the account can move.
