Zero-Party Data

Zero-Party Data is information customers intentionally and proactively share with a company about themselves, their preferences, their goals, or their context. It sits a step above first-party data (which is observed behavior on your properties) because it is declared rather than deduced. In a world of increasing behavioral data complexity, zero-party data is often the highest-fidelity and highest-trust input a B2B SaaS company has.

Why Zero-Party Data Is Growing in Importance

Third-party data is increasingly restricted. First-party behavioral data is powerful but can be misinterpreted (a login is not a use case, a click is not an interest). Zero-party data is what the customer actually told you. That makes it the strongest foundation for personalization, segmentation, and relationship marketing, especially in B2B where buying decisions involve context that is rarely visible in behavior.

The trust angle matters too. Customers who share zero-party data have actively given it, which creates an expectation that the company will use it well. Companies that honor that expectation build stronger relationships. Companies that ignore the data the customer took the trouble to provide train customers not to bother next time.

What Good Zero-Party Data Programs Collect

• Role and goals: what the user is trying to accomplish, what success looks like for them, what their priorities are.
• Preferences: channel, frequency, content type, language. The basics that make marketing feel respectful rather than intrusive.
• Context: company stage, team size, tech stack, integrations they care about. Useful for segmentation and personalization.
• Feedback and sentiment: structured surveys, review inputs, community polls, NPS open-ends. Customer opinion, declared.
• Advocacy willingness: references, case studies, reviews, speaking opportunities. Opt-in statements that inform advocacy programs.
• Product wishlists: what the customer wants the product to do. The richest roadmap input possible.

Where Zero-Party Programs Fail

• Collecting and forgetting. A survey that goes out, gets answered, and never surfaces in the customer's experience teaches the customer the company does not listen. The worst possible outcome.
• Asking too much. Long forms get abandoned or filled with noise. Each ask should be small, timely, and have an obvious benefit to the customer.
• Not refreshing. Preferences and context change. A customer's goals at month six are different from month one. Zero-party data needs periodic refresh.
• Siloed storage. If marketing collects preferences and CS cannot see them, the customer gets conflicting experiences and notices fast.

How Base Handles Zero-Party Data

Base treats zero-party data as a first-class input to the customer intelligence layer, not a marketing-only asset. Preferences, goals, feedback, and advocacy opt-ins collected through any surface are unified into the customer record, visible to marketing, CS, sales, and product. Requests for data are timed to the moments customers are most willing to share (onboarding checkpoints, post-success moments, advocacy invitations), with small, specific asks rather than long surveys. Collected data actually changes how the customer is served. That is how zero-party programs compound rather than decay.
