33Across

33Across operates a B2B adtech infrastructure model on the sell side of programmatic advertising. It integrates with publishers to monetise inventory, enriches supply with proprietary identity and audience data, and packages curated deal inventory for buyers transacting through DSPs. Value is created by improving fill, bid density, targeting relevance and CPM performance for supply partners, while giving advertisers and agencies more addressable and pre-filtered inventory.

33Across is a private adtech company that sells programmatic monetisation infrastructure and identity-enabled advertising products to publishers, advertisers, agencies and other adtech participants. Its core offering is a supply-side platform that helps publishers monetise display, video, connected TV and in-app inventory, supported by its proprietary Lexicon identity technology for cookieless addressability and cross-device recognition.

The company makes money primarily by taking a percentage of media spend or inventory value that flows through its SSP and curated private marketplace deals, with additional revenue from licensing audience segments and data-enabled targeting capabilities. Its value proposition is centred on improving publisher yield, increasing addressability in privacy-constrained environments, and packaging higher-quality supply for programmatic buyers.
