First-Party Data

First-party data is information a business collects directly from its own customers and audience through its own channels, such as a website, app, purchases, emails, and support. Because the company gathers it firsthand with consent, it is accurate, owned, and not shared with competitors.

First-party data includes everything you learn about a person through a direct relationship: what they browse, buy, click, ask, and tell you. It spans behavioral, transactional, declared, and engagement data, all collected on properties you control.

Its value is that you own it outright. It is more accurate than purchased data, it survives the decline of third-party cookies, and it is the foundation for personalization, measurement, and AI. The work is unifying scattered first-party data into one view per customer and using it responsibly.
