33Across
33Across is a cookieless SSP and identity platform for programmatic advertising.
Analyst Perspective
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.

Key insights about 33Across
Category Differentiation
33Across is not a media agency or a consumer social platform; it is a B2B programmatic adtech vendor focused on supply-side monetisation, identity and curated advertising deals. It should also be distinguished from generic data brokers because its core position is sell-side ad infrastructure rather than pure standalone data resale.
33Across: About
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.
How 33Across Works & Monetises
Business model analysis and core revenue streams
33Across primarily monetises via a percentage take-rate on programmatic media transacted through its SSP and curated marketplace deals. It also generates revenue from data licensing for audience segments and identity-powered targeting capabilities. Commercially, the business resembles SaaS infrastructure, but pricing appears tied more to media volume, deal flow, data usage and performance uplift than to fixed-seat subscriptions.

Amazon 'Add-to-Cart' Ads Coming to Samsung TV Plus
At NewFronts, Samsung Ads announced an integration with Amazon DSP that will bring Amazon’s interactive video ad technology to Samsung TV Plus in English this summer, surfacing on-screen "add to cart" buttons for products sold on Amazon. Brands without Amazon listings can use other CTAs like "sign up today" or "send to phone." Advertisers on Samsung will be able to measure outcomes using Amazon’s shopping, streaming and browsing data via Amazon Marketing Cloud. The newsletter also highlights growing credential‑theft ad scams that target agency buyers and AI chatbot power users—fraudsters are creating fake login or plugin pages (including faux Claude plugin pages) to harvest platform credentials—and summarizes Reuters/Oxford research showing Gen Z prefers social platforms for news (39% of 18–24-year-olds).
