Lucead

The business operates as a privacy-centric advertising marketplace and exchange on top of Google Chrome’s Privacy Sandbox infrastructure. On the supply side, it offers publishers a simple tag to list and manage their Privacy Sandbox inventory in pre-bid, define interest groups for their sites, and tune floor prices and exclusions. On the demand side, it provides agencies, demand-side platforms and advertisers tools to configure interest groups and bidding strategies for retargeting and other campaigns within the Privacy Sandbox framework.

Value is created by aggregating cookieless inventory, simplifying technical integration with the Privacy Sandbox, and allowing both sides of the market to transact programmatically without third-party cookies. The platform’s core economics resemble an ad exchange: it intermediates between supply and demand, improving fill rates and yield for publishers and providing addressable inventory and controls for buyers, without owning media inventory itself.

Lucead is a French advertising technology start-up that operates a cookieless ad marketplace built specifically on Google Chrome’s Privacy Sandbox. It provides a tag that publishers integrate into their sites to expose Privacy Sandbox inventory in pre-bid and configure interest groups and bidding strategies, while agencies, demand-side platforms and advertisers use the platform to buy and optimise retargeting and other campaigns without third-party cookies.

The company creates value by enabling publishers of any size to monetise Privacy Sandbox inventory and enabling buyers to access and manage this inventory through an open exchange. It generates revenue through a revenue-sharing take-rate on ad spend flowing through its marketplace, in line with standard ad exchange models. Its customers are digital publishers, media agencies, e-commerce and other advertisers, and buy-side platforms needing access to Privacy Sandbox-based inventory and tools.
