How Factori Powers Audience Intelligence on The Open Internet for The Trade Desk

The programmatic advertising industry has long operated under a structural tension.

On one side sit the walled gardens. These are closed ecosystems controlled by a small number of platforms, where audience data is abundant but opaque, locked to proprietary channels, and difficult to verify independently.

On the other side sits the open internet.

It is transparent, measurable, and much larger in reach, but it has historically lacked the same quality and scale of audience data.

The Trade Desk was built to address this problem.

Founded by pioneers of real-time bidding, The Trade Desk provides a self-service technology platform for data-driven digital advertising campaigns.

Buyers can use the platform to create personalized ad experiences across:

• Display
• Native
• Video
• Audio
• Social
• Computers
• Mobile
• TV

But operating one of the world’s leading independent DSPs creates a major data challenge.

The Trade Desk needs a continuous supply of high-quality, consent-compliant, behaviorally rich audience data.

That data cannot come from the walled gardens it competes against.

It also cannot depend on third-party cookies that are steadily disappearing from the ecosystem.

The Trade Desk’s platform evaluates more than 13 million impressions and quadrillions of permutations across the open internet every second.

Supporting decision-making at that scale requires data partners that can meet the same standards for quality, coverage, and reliability.

Why Data Partner Selection at The Trade Desk Is Not a Low Bar

Before looking at what Factori provides, it helps to understand what it takes to become and remain a trusted data partner on The Trade Desk’s platform.

The Trade Desk only allows pre-approved data sellers to distribute audience segments through its platform.

Segments from non-approved sellers cannot be added to The Trade Desk’s Data Marketplace distributions.

Getting approved requires a formal review.

Remaining approved over multiple years requires consistently meeting standards for:

• Data quality
• Taxonomy compliance
• Privacy-conscious sourcing

The Trade Desk’s Audience Unlimited initiative is a major expansion of its data marketplace.

It includes thousands of curated segments from hundreds of trusted, privacy-conscious third-party data providers.

Factori is one of them.

That distinction matters.

The Solution: Factori as a Long-Term Audience Data Partner

Factori provides Audience Data to The Trade Desk as a long-term data partner.

The data is available directly within The Trade Desk’s platform.

This makes it accessible to marketers, agencies, and brands running programmatic campaigns.

Factori’s audience data is built from behavioral and demographic signals processed at scale using AI and ML algorithms.

It studies billions of signals daily to profile users across global markets.

This is not a generic data feed.

The data is locally calibrated across fragmented markets and draws on direct partnerships with:

• Premium publishers
• Data providers
• Aggregators

Consent and privacy compliance are foundational requirements.

The Trade Desk’s data marketplace is designed to layer, enrich, and expand audience targeting using demographic, behavioral, and contextual signals.

Factori’s audience segments fit directly into this infrastructure.

They give The Trade Desk’s customers access to targeting signals that go beyond what first-party data alone can support and beyond what any single walled garden can offer.

Syndicated Audiences

Syndicated audiences make Factori’s segments available to any advertiser on The Trade Desk’s platform.

They are available at uniform rates and without restrictions.

This means a mid-market brand running a display campaign can access the same audience intelligence as an enterprise agency managing a global CTV campaign.

Custom Audiences

Custom audiences allow specific marketers to activate Factori data in targeted and exclusive configurations.

This supports use cases such as:

• Competitive conquesting
• High-value customer lookalike targeting
• Vertical-specific segment activation

These use cases require precision over breadth.

What This Looks Like in Practice

Consider a global consumer electronics brand preparing for a product launch.

Its agency is using The Trade Desk and managing spend across CTV, display, and audio at the same time.

The campaign needs to reach early adopters and tech-forward consumers.

The goal is not to rely on a keyword approximation.

The goal is to use behaviorally derived signals that indicate actual purchase intent and category affinity.

The Trade Desk allows advertisers to layer multiple high-quality third-party data segments on top of first-party data.

This makes it possible to target narrow and valuable audiences more precisely.

Factori’s audience data provides that third-party signal layer.

It adds demographic and behavioral intelligence that improves who sees the ad, when they see it, and on which device.

The campaign can run across channels without fragmentation.

The targeting signal travels with the impression, not with the platform.

The agency also has transparency into what data informed each targeting decision.

That is a standard closed ecosystems cannot structurally provide.

This is the open internet working as it should.

Factori is part of the infrastructure that makes it possible.

What the Multi-Year Partnership Signals

Short-term data partnerships are common in adtech.

Multi-year relationships with a platform as selective as The Trade Desk are not.

Factori has maintained this partnership across:

• Multiple years
• Platform upgrades
• Changing identity frameworks
• Industry-wide cookie deprecation

That continuity is itself a form of proof.

It reflects data that meets a consistently high bar.

The data must be:

• Accurate enough to support targeting at scale
• Privacy-compliant enough to withstand regulatory and platform scrutiny
• Reliable enough to remain in the marketplace as The Trade Desk evolves

The Trade Desk’s Audience Unlimited initiative reflects its belief that brands using third-party data to optimize campaigns can achieve stronger performance.

Factori’s continued presence in that marketplace means it is part of that strategy.

Samantha Jacobson, The Trade Desk’s Chief Strategy Officer, noted that “the complexity of the data marketplace to date has made the deployment of data somewhat anemic.”

Audience Unlimited is designed to address that by making third-party data a standard part of programmatic campaigns rather than an optional extra.

Factori’s audience segments sit within this shift from optional enrichment to always-on audience intelligence.

Stakeholder Quotes

No public statement from a named Trade Desk representative specifically referencing Factori was found at the time of writing.

If a direct quote exists internally from a partnership review, co-marketing call, or business review, it should be added here.

A single attributed line from a Trade Desk contact would significantly strengthen this asset.

The Result

Enabled Precise Audience Targeting on the Open Internet

Factori supports targeting across:

• Display
• CTV
• Video
• Audio
• DOOH

This can happen without relying on walled garden ecosystems or depreciating cookie-based signals.

Expanded Addressable Inventory

Factori provides behavioral and demographic signals that extend beyond first-party data limitations.

This gives brands and agencies on The Trade Desk more audience intelligence to work with.

Sustained a Multi-Year Partnership

Factori has maintained a long-term relationship with one of the world’s most selective programmatic platforms.

The Trade Desk formally reviews and approves data providers before granting marketplace access.

Supported the Shift to Privacy-First Identity Frameworks

Factori supports the wider move toward privacy-first identity frameworks.

This includes compatibility with emerging identity solutions such as UID2.0, which The Trade Desk is using as part of its next-generation targeting infrastructure.

Why This Matters for Marketers and Agencies Considering Factori

If your team already runs campaigns on The Trade Desk, Factori’s audience data is available to activate within the platform.

Teams can use the same platform and taxonomies they already work with.

The data is available at the quality standard required by The Trade Desk’s marketplace.

If you are evaluating audience data providers, the question is simple:

Whose data does The Trade Desk trust?

Factori is one of those providers.
