Companies Using RTB House

We detect RTB House on 33,926 domains, including Lenovo Group Ltd., LATAM Airlines Chile, Magazine Luiza SA. A detection means the technology is present on that domain, which for large organisations is often a single storefront or subdomain rather than a company-wide deployment. Among domains we matched to a company with a resolved industry, the most common is Retail (6.34%).

We detect 33,926 domains running RTB House across our monthly crawl of live business domains. Company data could be matched for 14,955 of them (44.1%), and every company-size, industry and country breakdown on this page describes that matched subset rather than the full detected base. A further 29,170 domains carried a RTB House detection previously and no longer do.

RTB House holds 43.18% of the Retargeting & Remarketing category, ranking #1. This is a share of the domains we detect running a platform in this category — not a share of all websites, and not a share of spending — so it is not directly comparable to figures published on other denominators.

The top alternatives to RTB House include Seznam Sklik (13.69% market share), Retention.com (12.33% market share), SharpSpring Ads (6.86% market share), Albacross (5.77% market share) — measured as a share of the domains we detect running a platform in this category.

United States leads with 5,637 matched RTB House domains, followed by United Kingdom (974), India (730), Brazil (618), Canada (467). These are counts within the 14,955 domains we could match to a company record, not the full detected base.

The most common company size is 1-10 employees, representing 55.93% of the RTB House domains we could match to a company record and size — a subset of 14,955 matched companies, not of all 33,926 detected domains. This is followed by 11-50 employees (22.47%) and 51-200 employees (11.12%).

Among the RTB House domains we could match to a company with a known founding date, most were founded in the 2020s (13.56%), followed by the 2010s (39.79%). That matched subset is drawn from 14,955 companies and is not representative of all 33,926 detected domains. This suggests RTB House is most popular among relatively young companies.

The ideal RTB House customer is: Company Size: 1-10 employees, Location: US, UK, or Brazil, City: São Paulo, Santiago, New York, Founded: 2010-2019, Company Age: ~7-16 years old — based on our analysis of 14,955 enriched companies at TechnologyChecker.io.

Yes. RTB House is a demand-side platform that buys display and video inventory programmatically on behalf of advertisers, differentiated by deep-learning bidding models. Our August 2026 crawl detects its tag on 33,926 domains. That figure counts both sides of the marketplace, though: 76.68% of those domains also carry Criteo, and supply-side platforms are heavily represented — PubMatic on 22.59%, Rubicon Project on 19.8% and Prebid header bidding on 19.07%.

Robert Dyczkowski is CEO of RTB House. The company was founded in 2012 in Warsaw, Poland, and now operates in more than 90 markets with roughly 1,600 staff across 30-plus offices. Poland accounts for only 1.8% of the enriched companies we detect running its tag, so most of its business sits outside its home market.

Yes. RTB House is an established Polish programmatic advertising company serving enterprise retail, media, banking and travel advertisers, and our August 2026 crawl detects it on 33,926 active domains across more than 60 countries. Named advertisers include Magazine Luiza and Casas Bahia in Brazil and Flydubai and Oman Air in the Gulf. Its 86% churn ratio reflects campaign cadence rather than instability — Criteo shows the same structural pattern at 69%.

RTB House bills on performance rather than a subscription. Its main model is dynamic cost per click, where bids adjust automatically per impression, and it also supports CPM and CPA arrangements depending on the campaign. There's no published rate card and no self-serve tier for its managed product, so pricing is negotiated per advertiser.

Both are retargeting DSPs and they mostly coexist rather than compete for a slot: 76.68% of RTB House domains also carry Criteo. By footprint Criteo is roughly 3.3 times larger, 110,313 domains against 33,926. RTB House differentiates on deep-learning bidding and built its base in markets where Criteo was less dense — Latin America, the Gulf, Southeast Asia. Because both tags can sit on the same page, budget shifts between them are invisible to a crawler.

Yes, and it's the company's main technical claim. RTB House moved its bidding engine to deep learning models rather than the logistic regression common in programmatic, and markets that as its differentiator for creative selection and bid pricing. Our crawl can confirm where the tag is deployed but not which model version serves a given advertiser.

Because they are selling inventory, not buying retargeting. Media categories total 17.89% of matched companies — broadcast media (4.78%), newspaper publishing (4.65%), book and periodical publishing (3.19%), online audio and video media (2.87%) and media production (2.4%) — nearly three times retail's 6.34%. The stack confirms the role: Google Publisher Tag appears on 36.17% of RTB House domains, with comScore (6.14%) and Chartbeat (2.75%) alongside, all publisher-side tools.

Through a JavaScript tag served from creativecdn.com, plus XHR calls to the same host. That mechanism has two consequences for this page. It only fires while a campaign or inventory deal is live, which produces the 86% churn ratio. And it sits alongside other ad tags rather than replacing them, which is why 76.68% of RTB House domains also carry Criteo and 46.16% carry DoubleClick Floodlight.

It has invested heavily in alternatives, and the detection data shows that work in progress: ID5, a shared identity provider built for a post-cookie environment, appears on 31.7% of RTB House domains, and LiveRamp Launchpad on 2.19%. Snowplow Analytics, which collects first-party event data, is on 23.96%. RTB House also participates in Google's Privacy Sandbox proposals. The high ID5 co-occurrence is the clearest signal that its inventory partners are preparing for deprecation rather than waiting for it.

Surprisingly few of the mainstream ones: Amazon Webstore appears on 3.83% of RTB House domains, Shopify on 2.37%, WooCommerce on 0.91% and Magento on 0.71%. The reason is that this base is enterprise and publisher-weighted rather than small-merchant. Adobe Experience Manager runs on 38.63% of RTB House domains against WordPress at 17.44%, an inversion that only occurs on large publishers and retailers running custom commerce stacks.

The current figure is 29,170 domains dropped against 33,926 still carrying it, an 86% churn ratio. That is campaign cadence rather than customer loss: a retargeting tag is present while a campaign is funded and gone when the budget stops, and on the supply side inventory relationships rotate as deals expire. Criteo shows the same structural pattern at 69% in the same crawl.

Extensively, and that is central to its strategy. After the United States (5,637 domains) and United Kingdom (974), the table runs India (730), Brazil (618), Canada (467), Spain (407), France (304), Japan (294), Turkiye (260) and Mexico (236) — an unusually flat distribution. RTB House is Polish and built its business in markets where Criteo's coverage was thinner, particularly Latin America, the Gulf and Southeast Asia.

Funding Choices, Google's own consent management platform, leads at 22.38% of RTB House domains, followed by OneTrust (3.96%), Consent Manager (3.09%), LiveRamp Launchpad (2.19%) and InMobi CMP (2.11%). The Funding Choices concentration is a publisher signal rather than an advertiser one: it is bundled with Google's ad monetisation stack, which fits a base where Google Publisher Tag appears on 36.17% of domains.
