Independent programmatic exchange

We don’t sell apps, we sell content environments.

Products

Intelligence, activation and operations in one stack.

Three products built to work together, plus AI Shelf, which shows how AI assistants talk about a brand.

Pantheon

Contextual intelligence engine and SSP for CTV and mobile apps. Cookieless, built on IAB Content Taxonomy 3.1.

Harion

DSP for branding and performance across CTV, mobile and web. Self-serve or managed.

MarkDash

Reporting and partner operations platform: live performance, optimisation signals and billing in one place.

AI Shelf

Brand visibility in AI answers: how often ChatGPT, Claude, Gemini and Perplexity name a brand, and the fixes that win more answers.

How it works

Supply, exchange, demand: one graph across CTV, app and web.

Every impression carries its content signals from the screen to the buyer. Nothing depends on cookies or user IDs.

01 SUPPLY

CTV, apps and web

CTV apps, OEMs, mobile apps and web publishers make their inventory available with full content context.

02 EXCHANGE

Markapp and Pantheon

Pantheon classifies each content environment in real time and packages it for buyers, IAB TCF compliant and OpenRTB native.

03 DEMAND

DSPs, agencies, brands

Buyers, including Harion, bid on context they can verify, with brand safety and IVT protection built in.
