What d-block does

D-Block is a privately-held French ad-tech company, founded around 2020 by two co-founders (Mathieu and Jean-César) with approximately 20 years of combined experience in web, media, and digital advertising. The company provides a technology platform that enables digital publishers and ad networks to monetize advertising inventory that would otherwise be blocked by end-user ad blockers. D-Block serves primarily small and mid-sized digital publishers alongside a secondary segment of ad networks and media regies, with a self-reported base of more than 100 publisher customers. The company is headquartered in France and operates globally via a bilingual French/English website.

D-Block's core product is a script-based technology stack developed after more than a year of internal R&D. The stack delivers advertisements in formats that comply with adblocker filter rules and the Coalition for Better Ads / Acceptable Ads standards (static IAB or native, Adsurface, in-page, and out-of-content placements). Implementation by a publisher requires only the insertion of a JavaScript snippet and an update to the publisher's ads.txt file; D-Block handles all technical interventions and maintenance at no cost. A complementary Publisher Dashboard provides daily monitoring of adblock rate, recovered revenue, impressions, and fill rate. Data is hosted on Google Cloud Platform in Europe, with no third-party cookies or persistent user IDs used.

The business model is a zero-upfront-cost, commission-based arrangement: publishers pay no setup, maintenance, or fixed fees, and D-Block earns a share of the incremental advertising revenue it recovers from previously blocked inventory. The company claims this delivers an average of 5% additional daily revenue recovery for publishers, and 40% more revenue uplift compared with intrusive anti-adblock wall popups. Go-to-market is product-led and self-serve, with enterprise and ad-network relationships initiated through a website contact form. The company has no disclosed outside funding, M&A activity, partnerships, patents, or certifications in the input data.

D-Block provides a proprietary technology platform that helps digital publishers and ad networks monetize audiences blocked by adblockers. Publishers install a single script and update their ads.txt to deliver Acceptable Ads-compliant advertising formats (Static IAB/Native, Adsurface, Inpage, Out of Content) that bypass adblocker filters without degrading user experience. The company operates on a zero-upfront-fee, revenue-share commission model, with all technical interventions and maintenance handled by D-Block.

The core D-Block Core Platform consists of a publisher script that must be inserted into web pages, combined with a Publisher Dashboard for real-time monitoring. The solution handles all technical interventions and maintenance on behalf of publishers, requiring only a script insertion and ads.txt update. The platform supports compliant advertising formats including Static ads (IAB or Native), Adsurface, Inpage and Out of Content placements.

Broad incumbents

• Eyeo (Adblock Plus / Acceptable Ads): Operator of Adblock Plus and creator of the Acceptable Ads initiative; defines the standard D-Block conforms to and is a critical incumbent in the adblocking ecosystem.
• DoubleVerify: Publicly traded ad verification and brand safety platform; competes for ad-tech spend at the impression-verification layer that D-Block partially addresses.
• Integral Ad Science (IAS): Established ad verification and optimisation company serving brands, agencies, and publishers — an adjacent incumbent in the broader ad-verification market.
• Taboola: Large content-recommendation and native advertising network serving publishers; competes with D-Block for publisher monetization budgets via alternative ad formats.
• FreeWheel: Enterprise ad management and monetization platform for premium publishers; a broad incumbent operating in the same publisher-revenue stack D-Block targets.
• Google Ad Manager: Dominant publisher ad server and programmatic stack; sets the ads.txt and ad-serving standards D-Block plugs into and competes against for publisher attention.

Direct peers

• Sourcepoint: Enterprise consent management platform that also includes adblock monetization tools for publishers; competes with D-Block in the publisher revenue recovery layer.
• Blockthrough: Direct competitor offering a publisher-side platform that monetizes adblocked traffic via Acceptable Ads-compliant formats, with the same 'recovery / revenue share' value proposition as D-Block.
• Admiral: Provides adblock recovery, consent, and reader engagement tools for digital publishers — closely overlapping D-Block's monetization focus while extending into consent and engagement.

Others

• Prebid.org: Open-source header bidding infrastructure widely adopted by publishers; D-Block integrates with this ecosystem rather than competing, but it defines the programmatic substrate D-Block sits alongside.
