 WHAT HARMONY DOES

One AI-Assisted Workspace from Audience to Media Plan.

Advertisers, agencies, and publishers use Harmony™ to move from a campaign brief to an optimized, exportable media plan, without stitching together spreadsheets and point tools.

Plan

AI-assisted audience discovery, powered by AudioGraph signals, and media planning across markets, stations, formats, demographics, and dayparts.

Purchase

Turn an approved plan into purchasing-ready output, with budget, flight, spot mix, and delivery goals defined up front. Execution from the Media Plan tab is coming soon.

Manage

Adjust budgets, reach and index trade-offs, and spot limits, and re-optimize plans as conditions change.

Analyze and Report

Evaluate plan delivery with audience measurement data: reach, impressions, GRP, CPP, CPM, and frequency.

AI ASSISTANT

Ask in Plain Language.
Get an Audience.

Harmony’s built-in AI assistant turns a campaign brief into a sized audience. Describe who you want to reach, and it discovers across AudioGraph signals, markets, and formats.

  • Understands the Brief

    Describe the audience and the markets the way you would to a colleague.

  • Finds and Sizes the Audience

    Matches segments, estimates in-market listeners, and identifies the markets they sit in.

  • Shows Where to Reach Them

    Top formats for the audience, ready to refine with the planning controls.

THE AUDIENCE LAYER BEHIND HARMONY™  

The Audience Layer That Makes Broadcast Radio Addressable.

Marketers have had to choose between digital precision and broadcast scale. AudioGraph unifies listener signals into an ID-based audience layer, so you can plan, buy, target, and measure the largest audio audience like the rest of the media mix. It launched with iHeartMedia and is being rolled out to other publishers in the U.S.

Addressable Measurable Easier to activate Built for business outcomes

How AudioGraph builds an audience

1

Collect Listener Signals

Data from streaming, podcasts, and device interactions from anonymous and registered online listeners.

2

Resolve and Enrich IDs

Privacy-safe matching through TransUnion, enriched with 600+ audience attributes.

3

Create a Unified ID

One listener ID that grows the addressable audience for smarter digital targeting and deeper listening insights.

4

Project to Broadcast

Digital listening data is mapped to broadcast stations, so plans reach audiences at the station and daypart level.

From Audience to Attributed Outcome

The same Unified ID follows the audience from planning through measurement,
so broadcast exposure can be tied to business results.

5

Place Ads Where Audiences Listen

Ads run in the stations and dayparts where the target audience is most likely to be listening.

6

Confirm Impressions

Each ad exposure is tagged and matched to Unified IDs in the targeted market and daypart, to verify who was reached.

7

Track Customer Actions

The same ID is linked to in-store or online actions such as purchases, visits or sign-ups.

8

Attribute Outcomes

Business outcomes are tied back to broadcast exposure through the Unified ID, using third-party measurement partners.

WHY IT WORKS

Cross-Audio Scale

 

Activates audiences across broadcast, podcast and streaming in one system, not a siloed dataset.

Modern Measurement

Connects audio exposure to business outcomes with measurement partners that marketers already trust.

Built for the Industry

Designed as a unified marketplace across broadcasters, bringing automation and accessibility to audio.

Human Influence

Pairs data precision with the voices listeners trust most. 80% of listeners consider hosts their friends, and 78% trust hosts’ product recommendations (iHeartMedia).

Harmony™ Plans on AudioGraph.

Plan, activate, measure, optimize. In Harmony, audience signals, markets, stations, formats, and dayparts are powered by AudioGraph, and buyer agents can query AudioGraph directly through the AudioGraph Signals Agent (release candidate).

THE HARMONY™ ECOSYSTEM

Planning Layer, Data Layer, Open Protocol.

Harmony does not work alone. It sits on AudioGraph, Triton’s audience data layer, and connects to buyers and sellers through AdCP, the open standard for agentic advertising. Each layer can be adopted on its own.

How the Pieces Connect
One model layer, many publishers. Modeling stays outside the protocol, and AdCP carries the transaction.

Outside the protocol · AudioGraph modeling

Publisher first-party data goes in, starting with iHeartMedia and rolling out to other U.S. publishers. Data science and audience models come out. Only model outputs cross into the protocol through the Signals Agent. Raw publisher data never enters AdCP.

CALLABLE FROM YOUR STACK

Any Buyer Agent or MCP-Compatible Tool Can Call Harmony™.

Harmony can be called by any AdCP buyer agent or directly over MCP, so you do not need the Harmony application to use Harmony. Discovery tools, planners, stewardship systems, DSPs, and other buy-side systems can call it from the tools they already run.

GOVERNANCE BUILT IN

AI Executes. Humans Stay Accountable.

Harmony works with AdCP’s Embedded Human Judgment (EHJ) model. Budget, brand, and compliance checks run before campaign actions execute, and decisions leave an auditable trail. Buyer, governance, and seller roles stay separate, so nothing approves itself. Oversight is architectural, not procedural. Read the five EHJ principles · AdCP governance docs
