Companies Using Criteo

With 10+ years in web crawling and technographic data analysis, I've examined Criteo's growth trajectory and customer profile using our 17,598 enriched company dataset, as of our April 2026 crawl at TechnologyChecker.io. Criteo (NASDAQ: CRTO) is now a $1.9 billion revenue company with roughly 17,000 clients, 3,649 employees, and offices in 20+ countries (per its Q4 2025 earnings release). We matched Criteo domains against LinkedIn company profiles to uncover who actually uses the platform, where they're located, and how the competitive dynamics are shifting.

Growth trajectory

Criteo first appeared in our crawler data in July 2005, the same year Jean-Baptiste Rudelle, Franck Le Ouay, and Romain Niccoli founded it in Paris. For five years, adoption stayed minimal: fewer than 20 active domains through mid-2010. Real traction started in late 2011, when active domains climbed past 100, then came explosive growth through 2013 and 2014 as the company's retargeting technology gained mainstream acceptance. Criteo IPO'd on NASDAQ in October 2013.

The most dramatic shift came in October 2017, when active domains jumped from 6,519 to 17,270 in a single month. This coincided with Criteo's expanded ad tag deployment. From there, growth was steady: 18,478 domains in February 2018 climbing to 51,071 at the December 2024 peak. That's a nearly 3x increase over seven years, driven by Criteo's pivot from pure retargeting to a full commerce media platform that today processes ~$1 trillion in ecommerce sales data and serves ~2 trillion ads per year (per Criteo's Q4 2025 fact sheet).

"Criteo's 20-year detection history tells a story of two phases: the retargeting era (2010-2017) built the foundation, and the commerce media era (2018-present) drove the 3x expansion from 18K to 51K active domains. The pivot wasn't cosmetic. It reshaped who uses Criteo and why." - Mehmet Suleyman, CEO at TechnologyChecker.io

Sales Signal: The consistent growth from 2018 through 2024 means Criteo's install base is relatively fresh. Most of the current 49,270 active deployments are less than seven years old. If you're selling ad tech services or complementary tools, target companies that adopted Criteo between 2020 and 2024, as they're likely still optimizing their setup and open to supplementary solutions.

Customer profile

Our enriched company data reveals a customer base that's smaller and more diverse than you might expect from an enterprise ad tech provider. 61.3% of Criteo customers have 1-10 employees, and when combined with the 11-50 range, 77.6% are small to mid-size businesses. This isn't strictly an enterprise play, though the enterprise segment is meaningful: 1.8% of customers have 10,001+ employees, including names you'd recognize instantly.

Vendor-verified customer stories on criteo.com feature enterprise brands like adidas (81% mid-funnel ROAS improvement in MENA markets), Sephora (+725% ROI across retargeting, audience match, and acquisition), Uber Advertising, and YSL Beauty (27% onsite CTR uplift). Our detection data confirms these and adds Marriott, Samsung, IKEA, Best Buy, American Express, and Costco. The age distribution is notable: 38.9% were founded in the 2010s and another 18.8% in the 2000s, meaning the majority of Criteo's customer base are digitally mature businesses between 5 and 25 years old.

Sales Signal: The sweet spot for selling alongside Criteo is companies with 1-50 employees (77.6% of the base) founded between 2005 and 2020. These businesses are sophisticated enough to run retargeting campaigns but small enough that they lack dedicated ad ops teams. For the enterprise 1.8%, pitch integration and optimization services, as brands like adidas and Sephora need help maximizing ROAS across Criteo and other demand-side platforms.

Industry and geographic concentration

Retail leads at 13.19%, which is expected for a commerce media platform. But the second-largest vertical isn't e-commerce or fashion. It's Technology/IT at 3.51%, followed closely by newspaper publishing (3.35%) and book/periodical publishing (3.21%). Together, publishing and media verticals account for over 10% of Criteo's customer base. This reflects Criteo's dual-sided model: retailers buy ads, and publishers sell the inventory. Motor vehicle manufacturing (2.65%), retail apparel (2.57%), and hospitality (2.21%) fill out the mid-tier.

Geographically, the United States leads with 31.2% of enriched companies (5,498), but the distribution is strikingly global. Brazil is second at 10.7% (1,889 companies), reflecting Criteo's strong position in Latin American e-commerce. France at 9.3% (1,630) shows the company's home-market strength, and Italy at 6.6% (1,165) rounds out a European bloc that collectively represents over 30% of the base. This geographic spread across the Americas, Western Europe, and increasingly Asia-Pacific makes Criteo one of the more internationally diversified ad tech platforms.

Sales Signal: The publishing vertical is an under-targeted opportunity. With over 10% of Criteo's base in newspaper, periodical, and broadcast media, there's a concentrated audience of publishers already monetizing with Criteo who need complementary tools for yield optimization, header bidding, and audience segmentation. For geographic targeting, the US/France/Brazil/Italy cluster covers over 57% of the install base, but the strong European footprint means localized outreach in French, Portuguese, and Italian will outperform English-only campaigns.

Migration patterns

Platform migration data reveals Criteo's competitive position in the advertising networks space. The biggest migration flow is with Google AdSense: 5,724 companies switched from AdSense to Criteo, but 12,823 moved the other direction. That's a negative 0.45:1 ratio, meaning for every company Criteo gains from AdSense, it loses 2.2 to Google's network. Against programmatic peers, the picture is stronger. AppNexus shows a 2.3:1 gain ratio (4,928 gained vs 2,189 lost), and PubMatic is even better at 3.0:1 (4,508 gained vs 1,483 lost).

In the last year, Criteo gained 1,303 companies from AppNexus and 1,198 from PubMatic, while losing only 183 and 124 respectively to those same platforms. The theTradeDesk migration is also positive at 2.5:1 (5,125 gained vs 2,054 lost).

"The asymmetry in Criteo's migration data is telling. It loses to Google AdSense at a 2.2:1 rate but gains from every major programmatic competitor. This positions Criteo as the preferred mid-tier platform: too specialized for Google's general-purpose network, but the winner when advertisers want commerce-specific retargeting." - Mehmet Suleyman, CEO at TechnologyChecker.io

Sales Signal: Companies that recently migrated to Criteo from AppNexus or PubMatic are actively rebuilding their ad stack. The 1,303 AppNexus-to-Criteo switchers in the last year need new integrations, creative optimization tools, and performance analytics. Conversely, the 1,373 companies that moved from Criteo to Google AdSense may have done so because they needed broader reach. If your tool bridges that gap (Criteo's targeting precision plus broader publisher access), you have a ready-made pitch.

Technology ecosystem

The tech stack data from Criteo's 17,597 enriched companies shows a measurement-focused customer base. Google Analytics appears on 88.41% of Criteo customer sites, well above the typical cross-industry average. Hotjar (22.25%) and Microsoft Clarity (20.55%) indicate that Criteo users are also investing in behavioral analytics to understand on-site engagement after the ad click.

The e-commerce layer confirms Criteo's retail focus: 14.71% have cart functionality detected, and platforms like Magento (1.65%) and PrestaShop (1.16%) show up consistently. On the CMS side, WordPress.com Hosting at 16.17% leads, followed by Drupal at 3.06%. Marketing automation is split between ActiveCampaign (7.71%) and Klaviyo (7.19%), with HubSpot at 3.30%. This three-way split suggests Criteo's customer base hasn't consolidated around a single email/marketing platform.

Sales Signal: The near-universal Google Analytics adoption (88.41%) combined with strong Hotjar (22.25%) and Clarity (20.55%) usage means Criteo customers are data-driven decision makers. They're already measuring campaign performance closely. If your tool offers attribution, incrementality testing, or cross-channel measurement, this audience is pre-qualified. The fragmented marketing automation stack (no single platform above 8%) is also an opening for consolidation pitches.

G2 review signals

Criteo Commerce Growth receives praise on G2 for ease of use (64 mentions) and effective retargeting (48 mentions). Users specifically call out the dynamic product recommendations (35 mentions) as a feature that works well out of the box. Audience targeting capabilities get 28 mentions, and campaign reporting gets 22.

The cons tell a different story. Inconsistent performance (31 mentions) is the top complaint, with advertisers reporting results that vary month to month. The platform UI gets 26 negative mentions for feeling outdated next to Google Ads and Meta's interfaces. Limited reporting granularity (19 mentions), customer support issues (15 mentions), and limited manual control (12 mentions) round out the pain points. The AI-driven optimization, while effective for hands-off advertisers, frustrates power users who want more levers to pull.

Sales Signal: The inconsistent performance complaint (31 mentions) creates an opening for supplementary tools that help advertisers benchmark and stabilize Criteo campaigns. If your product offers creative testing, audience analysis, or bidding optimization, lead with the consistency angle: "We see that Criteo's AI delivers strong months and weak ones. Our tool helps you understand why and smooth out the variance."

Key takeaways

1. Criteo has grown 3x since 2018. From 18K to 51K active domains, driven by the pivot from retargeting to commerce media. The growth trajectory has been steady and organic.

2. The customer base is surprisingly SMB-heavy. 61.3% have 10 or fewer employees. Enterprise names like Samsung and Marriott are real but represent less than 2% of the total.

3. Retail and publishing together define the platform. Retail at 13.19% plus publishing/media at 10%+ reflects Criteo's two-sided marketplace model.

4. Criteo wins against programmatic peers but loses to Google. Positive migration ratios of 2.3:1 (vs AppNexus) and 3.0:1 (vs PubMatic), but a negative 0.45:1 against Google AdSense.

5. Geographic diversity is a strategic advantage. Unlike US-centric ad tech platforms, Criteo has deep penetration in France, Brazil, Italy, and Spain. Over 30% of the base is in Europe alone.

6. G2 reviewers love the retargeting but hate the inconsistency. 48 mentions praise retargeting effectiveness, while 31 flag performance swings as the top pain point.

Sales applications

Outreach template for Criteo customers:

"Hi [Name], I noticed [Company] runs Criteo alongside [Google Analytics/Hotjar/ActiveCampaign]. Our data shows that Criteo customers using [complementary tool] see more consistent campaign performance. G2 reviewers highlight month-to-month variance as their top frustration with Criteo. Are you seeing similar patterns? Happy to share what we're seeing from similar [industry] advertisers."

Targeting strategy: Filter the Criteo install base by company size (1-50 employees), industry (retail, publishing, or hospitality), geography (US, France, or Brazil), and tech stack (using Google Analytics but lacking a marketing automation platform). This narrows to the highest-conversion segment: businesses running paid retargeting but without the tooling to fully optimize their spend.

Competitive angle: Don't position against Criteo directly. Position as the missing layer. Criteo's AI handles bidding and creative optimization, but the G2 data shows users want more transparency and manual control (12 mentions). Frame your pitch around visibility and control: "Criteo's automation works well when it works. We help you see what's happening inside the black box so you can catch underperformance before it costs you a full month's budget."
