Companies Using Sift

I write the detection rules for our crawl, and Sift's raw count turned out to measure platforms more than buyers. A domain counts when a page loads Sift's script or creates its command queue. Sift's snippet carries an account key, so on 15 October I read the key on samples of pages, then sorted every domain by the platform files it loads and by where its home page redirects. Of 12,154 live domains, 10,605, 87%, report to a platform's account rather than their own. The figures on this page use the 1,539 left after that cut and the removal of 10 for-sale or gambling pages, 432 of them matched to a company.

Where the 10,605 went

Salla is the largest: 4,743 stores on the Saudi store builder's Sift key, found in two passes. Toast is next, with 2,410 restaurant websites on one key; every Toast site I opened carried it. Teachable's course schools add 1,756, most of them also loading files from Hotmart, which owns Teachable. Then sahibinden.com, Turkey's classifieds site: 731 dealer store pages and dealer domains forwarding to them, on sahibinden's key. The tail repeats the shape: 255 Patreon creators, 158 Zola wedding sites, 124 sites behind Vercel's login screen, 86 Flickr photographers, 68 Dutchie cannabis menus, 48 Lunchbox ordering sites and 48 Kickstarter creators.

"Seven in every eight domains carrying Sift's script reported someone else's account. Salla and Toast alone made one Sift decision each that covered thousands of sites." - David Thomson, CTO at TechnologyChecker.io

Sales signal: the platforms are the prospects in the raw data. Salla, Toast, Teachable, sahibinden and Patreon each chose Sift once for thousands of sites. A restaurant on Toast never chose Sift.

What's left, and how far to trust it

The 1,539 still overstate distinct customers. About 720 are extra domains of companies that run several: Headout (52), DigiKey (50) and Wego (42) are among them. And in a browser sample of 49 remaining domains, about 5 still forwarded to a platform page by script, roughly one in ten. What remains is the same order of size as the 700-plus brands Sift's company page claims. Of the 50 companies in our table, 33 loaded Sift or set its key when I checked: DocuSign, Poshmark, Remitly, DigitalOcean, Depop, TaskRabbit, Course Hero, PandaDoc and Paula's Choice among them.

Sales signal: Sift's direct buyers are trust and safety or payments teams at internet companies with sign-ups to protect. Group the list by brand before counting accounts.

Who the customers are

36.67% of matched companies with a known size have 1 to 10 staff, but 20.05% have 51 to 200 and 23 have more than 1,000, including DocuSign, Veeam and Stitch Fix. Before the cut, restaurants and Salla stores filled the smallest band. Age points to the 2010s internet generation: 47.8% were founded in that decade, and Poshmark, Remitly, Depop, Stitch Fix and PandaDoc all in 2011. Technology, Information and Internet leads the industries at 11.25%, and Restaurants, the top industry before the cut, are down to 2.56%.

Sales signal: look for Sift on login and trial subdomains: DigitalOcean's cloud login, TaskRabbit's booking site, Veeam's web store. A homepage-only scan misses many of its customers.

Where they are

The United States has 242 of the 432 matched companies, 56%. Mexico (24), Australia (18), Germany (14) and the United Kingdom (13) follow at a distance. Saudi Arabia, a top-two country before the cut, has 7 now, which shows how much of the old chart was Salla. The international names are app and marketplace companies: Depop in London, Sendcloud in the Netherlands and Wego in Singapore.

Sales signal: outside the US, Sift's customers are scattered. A regional partner will find a few dozen accounts per country, not hundreds.

Beside the checkout tools

Sift's switching table is empty. 73 domains run Sift and Riskified today, out of 113 ever seen with both; 56 run Sift and Forter (64 ever) and 10 run it with ClickCease (18). Most pairs still run both, so none passes our test for a switch. NoFraud, a Shopify order app, shares no live domain with Sift at all. Where Sift meets a checkout tool, it can guard sign-ups and logins while the other approves orders.

"Sift and Riskified run side by side on 73 sites. Sift scores sign-ups as well as orders, so the two don't have to compete." - David Thomson, CTO at TechnologyChecker.io

Sales signal: pitch Sift against account-fraud tools rather than chargeback guarantees. Its overlap with Riskified and Forter looks like division of labour.

The stack around it

Google Analytics runs on 73.62% of Sift domains and OneTrust on 23.98%. PayPal (13.19%) and Stripe (13.0%) each sit on about 200 domains, while Shopify is on 2.86% and WooCommerce on 6.63%, the opposite of NoFraud and Signifyd, whose sites are Shopify stores. Braze (5.26%) and Snowplow (8.84%) point to app companies with product and lifecycle teams.

Sales signal: subscription billing, identity verification and customer-messaging tools fit Sift's customers better than shop apps do.

What it costs

Sift publishes no price list. Its help centre, checked on 15 October 2026, says it invoices monthly, payable in US dollars within 30 days, and ties charges to the events a customer sends, such as $create_order and $create_account, with a custom plan for businesses that don't send them. Its company page says it has fought fraud since 2011.

Sales signal: event-based pricing grows with sign-ups and orders, so fast-growing apps renegotiate often.

Key takeaways

1. 1,539 live domains run Sift on their own account, 14th of 32 with 1.02%.

2. 87% of the raw footprint, 10,605 domains, is platforms: Salla 4,743, Toast 2,410, Teachable 1,756.

3. About 720 of the 1,539 are extra domains of a few dozen companies.

4. Customers are internet companies: DocuSign, Poshmark, Remitly, Depop.

5. Riskified and Forter run beside Sift on 73 and 56 domains, and neither pair passes our switching test.
