Companies Using Sirdata

I expected Sirdata to show up in our October 2026 crawl as a data company. It mostly shows up as a cookie banner. A domain counts here when a page loads Sirdata's consent scripts from consentframework.com, its audience script from js.sddan.com or its contextual script from sirdata.io, or sets up the banner's SDDAN.cmp object. Raw, that's 6,328 live domains. 1,489 of them run the banner under a platform's Sirdata account, Apimo's estate-agency sites and Forumactif's forums, so we count the platforms as the customers and set those sites aside. That leaves 4,837 live domains, 2,785 matched to a company, 8th of 68 in Customer Data Platform. When I opened 14 random raw domains in a browser, 13 still ran Sirdata and all 13 loaded the banner; three of them were Apimo sites.

Banner first, data second

Our script logs cover 4,322 of the counted domains. 3,990 of them loaded the consent banner, and 1,425 of those also loaded Sirdata's audience and contextual scripts; 137 loaded the data scripts without the banner. When the data scripts run, they're busy. On lsmart.co and cimexprotect.com they called about a dozen ad-tech hosts for cookie matching, Xandr, PubMatic, Smart AdServer and Lotame among them, before anyone touched the banner. Sirdata's pricing page explains why a site would accept that: it can get the CMP "with no direct costs" if the data collected on it is valuable enough.

Sales signal: treat this as a consent-management list with a data-sharing subset. The 1,425 domains running both are sites that let a data vendor's scripts run beside the banner, a narrower and more ad-funded group than the rest.

Two platforms, set aside

Sirdata puts an account number in the banner's script address, so we can count accounts as well as domains. On the raw set, Apimo's account covered 1,034 domains with one banner configuration. They are estate-agency websites built by Apimo: 7 of the 8 I opened credit "Design by Apimo" in the footer, and the eighth loads the same Apimo code. Forumactif, the free forum host, covered 393 domains under its own account. Left in, those two made Real Estate a quarter of matched companies and made Sirdata look like a property-sector tool. On the counted domains the picture is a long tail: 1,411 accounts we could read, 917 of them on a single domain. The biggest remaining account covers about 250 tourism sites and a food-blog network covers 118.

Sales signal: for the Apimo sites, the decision sits with Apimo, not the agency. A consent vendor would pitch Apimo once. The cleaned list is the one worth prospecting: the companies named on this page run Sirdata on their own websites.

One clean month, and slow churn

October 2026 is the first month we count Sirdata on the cleaned basis, so the chart has one point. Future points will move for reasons besides adoption, because the domain set we crawl turns over every month, with dead sites leaving and new ones arriving, and our detection widens over time. Churn is measured on the raw basis: 638 domains dropped Sirdata on at least one hostname since we started tracking it on 16 March 2026. When I re-checked 16 domains that had dropped it everywhere, 14 no longer loaded it, and three of those were infobel's country directories, which now show Quantcast's banner.

"Sirdata is filed as a customer data platform, but on the pages we crawl it is a consent banner first. Most of its sites never load anything else from it." - Emma Davies, Data Analyst at TechnologyChecker.io

Sales signal: a stable pool of just under 5,000 domains. Real churn exists but it's slow, so targeting matters more than timing.

Who the customers are

58.98% of matched companies have 1 to 10 employees and 26.08% have 11 to 50. Founding dates spread wide: the 2010s lead with 36.72%, but 6.33% were founded before 1960, including L'Humanité (1904) and the Ordre de Malte France (1927). Among the 31 companies above 1,000 staff are Médecins Sans Frontières, Ipsos, Yoplait and HR Path, all running Sirdata on their main websites.

Sales signal: small French businesses dominate by count, but the named organisations, charities and schools are where a deal is worth the effort. Filter by company size before you write the first email.

A French product with French customers

France holds 2,174 matched companies, 79.87%. Add Réunion and the four neighbouring countries on the list (Belgium, Switzerland, Luxembourg and Monaco) and it reaches 84.13%. The United States has 109 and Spain 105. With the platform sites out, no industry reaches 5%: Retail leads at 4.98% and Travel Arrangements follows at 4.74%, tourist offices included. Schools and charities fill much of the named list, several of them with the banner on a donation or course site.

Sales signal: outside France the list is thin. If you sell into Sirdata's base, sell in French and lead with TCF and Consent Mode compliance, which is what these sites bought.

Running both, and leaving

No switching flow passes our tests. Only 5 domains run Sirdata with Permutive today and 6 with Segment, so the data platforms in our CDP table aren't where Sirdata's customers go. The consent tools tell you more. Funding Choices, Google's own consent messaging, runs on 4.51% of counted Sirdata domains, and Axeptio, CookieYes, Complianz, tarteaucitron.js and Didomi each sit under 1%. Of the 14 sampled leavers without Sirdata, four showed another banner: three infobel directories on Quantcast and one lighting brand on Cookiebot.

"When a site leaves Sirdata, it swaps one banner for another. In my sample, none left for a data platform." - Emma Davies, Data Analyst at TechnologyChecker.io

Sales signal: competing CMPs should expect replacement deals, one banner out and one in. Data platforms have little to win from this list.

The stack around it

Google Tag Manager runs on 91.61% of counted Sirdata domains and Google Analytics on 87.89%, which fits a banner sold as Consent Mode v2 ready. WordPress is on 52.33% and Elementor on 14.12%. Don't take the AdSense row at face value. Its 71.8% is mostly Sirdata itself: the banner script creates an AdSense queue to pause ad requests until consent, and our AdSense check counts that queue. Only 189 of the 4,322 counted domains in our script logs requested AdSense's script. The audience script's cookie-matching calls, Rubicon Project's pixel among them, probably lift that row too.

Sales signal: tag-management and analytics consultancies have an easy opener, since nearly every site runs GTM behind the banner. Ad-tech sellers should check a Sirdata site's ad slots before assuming it runs AdSense.

What it costs

Sirdata's pricing page, checked 13 October 2026, lists the ABconsent Smart plan from €25 a month, priced by page views up to 10 million a month, with unlimited domains and a 14-day free trial; annual billing takes 10% off. Enterprise plans are quoted, and there's a partner programme for agencies and freelancers. The data-funded route covers the CMP's cost for sites whose audience data qualifies. Sirdata says ABconsent is a Google CMP Gold Partner, IAB TCF compliant and hosted on servers in Europe.

Sales signal: at €25 a month the banner is a small line item, so price won't move these customers. Compliance help and setup support might, and those are what Sirdata's own customer quotes praise.

Key takeaways

1. 4,837 live domains after setting aside 1,489 platform-run sites, 8th of 68 in Customer Data Platform, yet 3,990 of 4,322 inspected domains load the consent banner.

2. Apimo's estate-agency sites and Forumactif's forums run Sirdata under the platforms' accounts and are not counted.

3. 79.87% of matched companies are French and 58.98% have ten or fewer staff.

4. Real churn is slow, and the leavers I checked moved to other banners.

5. The 71.8% AdSense overlap is Sirdata's own consent queue, not ad revenue.

How to use this list

Filter by company size and country first, then check whether a site loads Sirdata's audience scripts as well as the banner. For the full list of 4,837 Sirdata domains with company, size and stack data, explore TechnologyChecker.io, and compare the banners in our Consent & Privacy Management table.
