AdDefend

The company operates an adtech infrastructure layer between publishers with adblocked inventory and advertisers seeking incremental reach. It integrates via tags and server-side connections into publisher ad stacks to detect adblock usage and reinsert acceptable display and video ads into blocked placements. On the demand side, it exposes this recovered inventory through a programmatic adblock channel available in major DSPs and also via a publisher self-service adserver.

Value is created by turning otherwise unmonetisable adblocked impressions into sellable inventory for publishers, and by providing advertisers with access to a distinct audience segment that is normally unreachable via standard programmatic pipes. Commercially, the company functions similarly to a specialised ad network / yield solution focused on adblocked traffic, offering analytics, planning predictability, and delivery guarantees on recovered impressions.

AdDefend is a German advertising technology company that enables publishers and advertisers to monetise web users who run adblockers or use private browsing modes. Its platform detects blocking technologies and serves compliant display and video ads into previously blocked inventory, integrating with publishers’ ad stacks and major demand-side platforms via a dedicated programmatic channel.

The company generates revenue by selling these recovered impressions to advertisers on a CPM basis through direct and programmatic direct deals, and by operating a publisher-facing platform and self-service adserver that manages campaign delivery and reporting. Its direct customers are digital publishers, advertising buyers and trading desks seeking incremental reach among adblock users and recovery of lost advertising revenue.
