Picture segmentation as a flow rather than a filter. Governed source data becomes unified person and account context, that context feeds audience criteria, qualifying audiences get activated, activation opens into an account or buying-group journey, and measurement feeds the loop back to the start. Each handoff depends on the one before it, so the quality of the foundation decides the quality of everything downstream.
That foundation is unified data. Adobe Real-time Customer Data Platform and its B2B Edition can unify cross-source B2B data into person and account profiles, support person-to-account relationships and account hierarchies, and enable account-level audience evaluation and activation. In practice that means resolving "this lead, at this company, connected to this opportunity" into a single profile you can segment on, pulling together CRM records, marketing-automation activity, and third-party intent signals, then matching people to the accounts they belong to.
The hard part lives in that matching. The same person can appear in three systems under slightly different names, and the same account can surface as both a parent company and a subsidiary, so the logic that reconciles them decides whether your account audiences are trustworthy at all. This is where the richer B2B variables start to pay off: firmographics tell you what kind of company you're looking at, technographics tell you what they already run, and behavioral and intent signals tell you what they're researching right now. Layered together, those signals turn a flat list of accounts into a ranked, explainable view of who is worth engaging and why.
Be honest about the ceiling on all of this. An audience is only as good as its source data, its identity and account-matching logic, its definitions, and its governance, so unifying profiles supports better account context without guaranteeing complete or correct identity, buying-group membership, consent, or a business result. Weak inputs still produce weak segments, which is why many teams get their profiles right first, a step Adobe walks through in its guide to building customer profiles.
