Buyer Access
Source consented, quality-scored audience segments for institutional campaigns, marketing teams, academic research, or journalism — the most defensible data supply chain you can put in front of a regulator.
Available Audience Segments
Filter by type, locale, income band, and quality. Each audience segment carries a composite score so you can buy on evidence, not adjectives. Upper and Enterprise tiers add CSV/API export and the economic overlays below.
Set your target size, quality floor, and type. The builder selects the highest-scoring segments from available supply, assembles them into a single cohort, and exports a customer file ready for Google Customer Match, Meta Custom Audiences, UID2, or LiveRamp onboarding.
| Audience Segment | Type | Locale | Income | Freshness | Records | Quality | Access |

Quality matters more than volume. Both Google Similar Segments and Meta Lookalike Audiences use deep learning models optimised for signal coherence — not seed size. A Premium-tier YouDB audience (quality score 85+) achieves better match rates and more accurate model expansions than a larger, lower-quality seed. Spend on quality. The platforms handle scale.
Once you unlock an audience segment, you receive a customer file: a CSV of hashed emails and cookie identifiers, one row per consented record. This is the format every major ad platform accepts natively for first-party data activation. The flow is the same regardless of platform.
Customer Match & Similar Segments
Upload your customer file (SHA-256 hashed lowercase emails) via Audience Manager → Customer Match. Google matches against signed-in users across Search, Gmail, YouTube, Display, and Maps. Enable Similar Segments and Google’s deep learning model finds behaviorally similar users across the full Google ecosystem, scaling reach without additional data spend.
Recommended upload: 1,500–2,000 records · Typical match rate: 40–60%
Custom Audiences & Lookalike Audiences
Upload via Business Manager → Audiences → Custom Audience → Customer List. Hashed emails match against Facebook and Instagram users. Create Lookalike Audiences at 1–10% of any target country — Meta’s neural network finds the closest behavioral analogues at whatever scale you specify.
Recommended seed: 1,000+ records · Typical match rate: 50–70%
Unified ID 2.0 (UID2)
UID2 is an open-source identity standard built on hashed emails — the native format for YouDB’s email-linked records. Onboard directly or via LiveRamp and distribute matched audiences across The Trade Desk’s DSP and its publisher network.
Recommended seed: 500+ authenticated records · Email-linked data preferred
Onboarding & Multi-Platform Distribution
Upload your customer file to LiveRamp’s onboarding service. LiveRamp resolves identities and distributes your matched audience to 500+ ad platforms, DSPs, and publishers simultaneously. LiveRamp charges a per-record onboarding fee negotiated separately from YouDB.

Minimum seed sizes for reliable activation
YouDB’s mission is to convert the “data broker” industry into a consensual transaction between informed sellers and buyers.
GDPR fines have exceeded €4B since 2018. CCPA enforcement is active. The FTC has brought actions against data brokers on unfair-practice grounds. The direction of travel is not ambiguous. What is ambiguous is your position within it.
Every dataset without a consent chain is a liability waiting to be surfaced. When your legal team is asked how you obtained this data — and in an enforcement environment, they will be asked — “we purchased it from a third party” is the beginning of the answer, not the end. What follows matters. YouDB data has a complete answer.
Consented, authenticated, email-linked data consistently outperforms inferred or aggregated alternatives on match rate, conversion, and suppression accuracy. You are not paying an ethics premium. You are paying for data that performs better because it is more honest about what it is.
The honest comparison
There are many ways to source behavioural data. There is only one way to source it with a consent chain and a full audit trail attached. The datasets built on inferred consent, aggregated without disclosure, or scraped from surfaces that never intended to be data products have served the industry for twenty years. They will continue to be available. They will continue to be cheaper.
They will also continue to attract the scrutiny of regulators who are, increasingly, no longer confused about what they are.
We do not expect you to stop buying data. We expect you to know the difference between data that arrived with its provenance intact and data that did not. That difference — once invisible in practice — is now something your legal team, your compliance officers, and eventually your board will need to be able to articulate.
YouDB is the articulation.
The supply chains that cannot answer “Where did this data come from?” with a consent-driven response will face endless headwinds.
