Data & Enrichment

# First-party data

In short

First-party data is data you collect yourself, through your own systems and direct relationships. Examples are CRM records, form submissions, website and product activity, email engagement, and support conversations.

It is usually the most relevant and trusted data a team has, because you know where it came from and under what terms it was collected. It is also the foundation you enrich with outside data.

## Common sources

* **CRM and sales activity:** Accounts, contacts, deals, call notes, and meeting outcomes.
* **Website and forms:** Visits, page views, form fills, chat transcripts.
* **Product usage:** Logins, feature use, and activation milestones.
* **Marketing and billing:** Email opens and clicks, event attendance, plans, and renewals.

## First-, second-, and third-party data

* **First-party:** Collected by you directly.
* **Second-party:** Another company's first-party data, shared with you by agreement.
* **Third-party:** Aggregated by a provider from many sources and sold broadly.
* **Zero-party:** Information a person intentionally tells you, such as stated preferences.

## How GTM teams put it to work

### Find your best customers

Closed-won, retained, and expanded accounts show which traits predict success. This feeds your ICP and scoring models.

### Prioritize active accounts

Say a prospect has visited pricing three times this week and a trial user invited two colleagues. Those first-party signals justify immediate outreach.

### Fill the gaps

First-party data is rich but incomplete. Enrichment adds firmographic and contact fields to the records you already own.

## Privacy and quality

First-party data is not exempt from privacy rules. You still need a lawful basis, clear notices, and the ability to honor deletion and opt-out requests. This is general information, not legal advice.

Keep it clean: duplicates, stale contacts, and inconsistent formats reduce its value quickly.

## Common mistakes

* **Siloed systems:** Product, marketing, and CRM data that never meet can not drive scoring.
* **No ownership:** Without a clear owner, fields drift and definitions diverge.

## First-party data FAQs

**What is first-party data?**

First-party data is information a company collects directly from its own customers, prospects, and channels, such as CRM records, form submissions, product usage, and website behavior. You own the relationship and know how the data was gathered.

**What are examples of first-party data in B2B?**

Examples include CRM accounts and contacts, demo requests, email engagement, website visits, product usage events, support tickets, and purchase or renewal history. All are collected through your own channels.

**How is first-party data different from third-party data in B2B?**

First-party data is collected directly by you. Third-party data is gathered by an outside provider from many sources and sold to multiple buyers. First-party is typically more specific to your business; third-party adds broader coverage.

**Is first-party data subject to privacy laws?**

Yes. Collecting data directly does not remove obligations such as having a lawful basis, giving notice, and honoring access and deletion requests under laws like GDPR. This is general information, not legal advice.
