Martailer

Martailer provides B2B retail media infrastructure that lets retailers and marketplaces monetise their owned channels with sponsored listings, display and video advertising. It creates value by giving clients control over ad inventory, pricing, auctions, advertiser access and first-party data activation under the retailer's own brand. The company monetises this infrastructure through software access and related service layers rather than by operating a consumer-facing media property.

Martailer is a Lithuanian retail media technology company operating as a white-label platform provider for retailers and marketplaces. Its core product enables clients to build and run their own retail media networks across onsite, offsite and in-store inventory, combining ad serving, auction mechanics, first-party data targeting and reporting. The company also offers an advertiser-facing self-service portal and bespoke implementation support for retail media programme rollout.

Its customers are businesses rather than consumers: primarily e-commerce retailers, marketplaces and retail media teams, with secondary users including brand advertisers, vendors and agencies that buy media through retailer-owned environments. Martailer generates revenue mainly from software licensing or subscription fees for its hosted platform, with additional income likely from implementation, support and custom programme services.
