What Ozone does
Ozone aggregates digital advertising inventory from premium publishers into a unified marketplace and enables advertisers and agencies to buy that inventory programmatically. It creates value by combining scaled publisher supply, consent-based audience data, identity mapping, campaign activation and reporting in one platform. For publishers, it aims to improve monetisation and control; for buyers, it offers brand-safe reach, cross-publisher targeting and operational simplicity versus fragmented direct deals.
Category differentiation
This is the UK advertising technology company Ozone Project, not a general air purification, telecoms or software company using the Ozone name. It operates a premium publisher advertising marketplace rather than a consumer media brand or standalone DSP.
Strategic context
AI-supported assessment from the existing company research; distinguish interpretation from sourced facts.
Ozone is a UK-based advertising technology company operating a programmatic marketplace for premium publisher inventory. Its core product is an audience connection platform that gives advertisers and media agencies a single buying point for digital ad space across a network of participating publishers, while also providing publishers with monetisation, reporting and administrative tools. The company positions itself around publisher control, consented data usage, brand-safe environments and an alternative route to audience reach outside the largest walled gardens. The business makes money primarily from programmatic advertising transactions, taking a share of media spend or monetisation margin on inventory sold through its platform. It also generates revenue from managed creative production through Studiozone and from premium format execution and audience intelligence capabilities layered onto campaigns. Its direct customers are advertisers, media agencies and premium publishers rather than end consumers.
Company news briefing
Briefing updated:
Continuing to address Q2 2026 programmatic inventory declines driven by AI-powered search disruption, Ozone has launched Arc, a new product capability designed to help advertisers optimise performance-led outcomes across its premium publisher network. Highlighting the collaborative publisher model's scale—which reached 42% of the UK population daily in 2025 and drove over £400 million in ad spend—industry analysts point to Ozone as a key framework for European media cooperation amid ongoing referral traffic challenges.
Business model & monetisation
The company monetises mainly through percentage take-rates or marketplace margins on programmatic media transactions executed across its publisher alliance. Secondary revenue comes from managed creative production, premium ad formats and campaign support services. Additional value-based monetisation likely comes from consented audience intelligence and targeting capabilities embedded in campaign execution, alongside publisher revenue-sharing based on inventory and audience contribution.

TeqBlaze Joins AgenticAdvertising.org to Boost Sell-Side Agentic Ads
Agentic Advertising · Recorded impact score: 3/5
TeqBlaze, an independent ad tech vendor, has joined AgenticAdvertising.org (AAO), the nonprofit trade organization behind the Ad Context Protocol (AdCP) for agentic advertising. Since earlier this year, TeqBlaze has been testing AdCP through its Sales Agent MVP, a free environment for publishers and SSPs. The agent allows sellers to add inventory via a simple interface or TeqMate AI prompt, receive requests from buyer agents, and approve or reject deals, with human sign-off required before rendering and invoicing. This membership provides TeqBlaze with access to AAO's working groups and governance. The move underscores the industry's shift toward agent-to-agent selling. TeqBlaze, which joined IAB Tech Lab in 2024, also participates in its Agentic Advertising Management Protocols (AAMP) and ARTF efforts, highlighting the need for interoperability across parallel protocol initiatives.
