Data & Enrichment

# B2B database

In short

A B2B database is an organized collection of business records, typically companies and the professionals who work at them, stored so that they can be searched, filtered, and exported. It can be a vendor database you license or your own in a CRM.

The key word is database: a stored set of records. The tools around it, such as enrichment and integrations, belong to a data platform. The quality of the database sets the ceiling on everything you build from it.

## What a B2B database contains

* **Company records:** Name, domain, industry, size, location, and technologies.
* **Contact records:** Name, title, seniority, department, email, and phone.
* **Relationships:** Links between people and companies, and between parents and subsidiaries.
* **Metadata:** Source, last updated date, and verification status.

## Two kinds of B2B database

### Your own database

The accounts and contacts in your CRM. It holds your history, but only for companies you already know.

### A licensed database

A vendor-maintained set covering much of the market. It helps you find companies you have never touched.

---

## How to use one

### Translate your ICP into filters

Industry, size, region, and technologies become search criteria.

### Select roles, not just companies

Use job title, seniority, and department to find buyers.

### Check against your CRM

Exclude existing customers and open opportunities before outreach.

### Verify before sending

Validate emails to protect deliverability.

## Example

Say a team wants software companies of a certain size in one region. A database filter returns the matching companies. The team removes those already in the CRM, picks two buyer roles at each, verifies emails, and loads the list into a sequence.

## Common mistakes

* **Judging by record count:** Size says nothing about fit or accuracy.
* **Exporting and forgetting:** Exported lists go stale quickly. Refresh them before reuse.
* **Ignoring terms of use:** Licenses may limit how data is stored or shared.

## B2B database FAQs

**What is a B2B database?**

A B2B database is an organized collection of company and contact records that can be searched, filtered, and exported. Sales and marketing teams use it to find target accounts, identify buyers, and build prospect lists.

**What is the difference between a B2B database and a CRM?**

A CRM stores the accounts and contacts you already work with, along with your activity history. A B2B database covers a wide market, including companies you have never contacted, and is mainly used to discover and enrich prospects.

**How do you build a B2B database?**

You can license one from a vendor, grow your own through forms and sales activity, or combine both. Define your ICP, collect the key fields, deduplicate, verify contact details, and set a schedule to refresh records.

**How accurate are B2B databases?**

Accuracy varies by source, region, and how recently records were verified. Measure it yourself by testing a sample, for example by checking email bounce rates and confirming job titles, rather than relying on vendor claims.
