What Dianomi does
Dianomi operates a two-sided ad marketplace. On the demand side, it sells access to premium contextual and native inventory to advertisers and agencies through both managed service and self-serve buying tools. On the supply side, it helps publishers monetise web, app, email and related inventory using native, display, video and audio formats. The company creates value by curating premium publishers, matching advertiser demand to contextually relevant placements, and providing reporting and targeting layers that improve campaign performance and publisher yield.
Category differentiation
Dianomi is not a general-purpose DSP or a broad consumer publisher. It is a premium native and contextual advertising marketplace with self-serve and publisher monetisation capabilities.
Strategic context
AI-supported assessment from the existing company research; distinguish interpretation from sourced facts.
Dianomi is a UK-based advertising technology company operating a premium native and contextual advertising marketplace. It connects advertisers and agencies with curated publisher inventory, with particular strength in finance, business and other high-value editorial environments. The company also provides self-serve campaign management, audience targeting, advertiser analytics, and publisher monetisation tools. Dianomi makes money primarily by taking a margin between advertiser spend and publisher payouts across its marketplace, using performance-based pricing such as pay-per-engagement and related campaign pricing models. Its direct customers are advertisers, media agencies, publishers, and ad operations teams that want brand-safe contextual distribution, privacy-first targeting, and transparent reporting.
Company news briefing
Briefing updated:
Taboola's proposed acquisition of Dianomi for £19 million to £27 million remains on track for late 2026, pending shareholder approval and regulatory clearance. The planned integration into Taboola's Realize platform aims to expand its financial vertical reach, supported by ongoing industry discussion surrounding ad tech consolidation. Concurrently, Dianomi continues to execute its event roadmap, partnering with Mumbrella for the Financial Services Marketing Summit in Sydney and preparing its Behavioural Finance Series.
Business model & monetisation
The core monetisation model is media margin on marketplace spend: advertisers fund campaigns and Dianomi retains a spread between media spend and publisher payouts. Pricing is primarily performance-led, especially pay-per-engagement, with support for campaign budgets and CPC-style mechanics. Additional revenue likely comes from premium pricing tied to curated inventory, contextual audience targeting, and optional managed campaign support rather than pure seat-based SaaS subscriptions.

- Pay-per-engagement / CPC-style charging

Acquisitions · Recorded impact score: 3/5
This AdExchanger podcast episode discusses two ad tech acquisitions from last Friday: Infillion's acquisition of Foursquare, adding location data to its ad tech stack, and Taboola's acquisition of Dianomi, targeting the finance vertical. Editor-in-Chief Allison Schiff provides rationale and potential synergies. The episode also covers the Warner Bros.-Paramount merger, now dubbed 'WarnerMount', as the major antitrust hurdle was resolved when California and 11 other states settled their lawsuit.

The discussion highlights the strategic moves in ad tech consolidation and the significant regulatory scrutiny on major media mergers.
