A company domain is the website address used to represent a business.

## Why it matters

Use a repeatable lookup key when researching or organizing companies.

## Illustrative example

A sales team uses a business's main website domain to find its CRM record.

## What to check

A company can own several domains, and subsidiaries may use different ones.

## How Data SDK fits

Data SDK connects website visits with available company details worldwide, from startups to larger businesses. Coverage and fields vary. Start free trial opens an email request; terms are confirmed with the team. The full API is coming soon.

These are suggested workflows, not a list of built-in integrations. Use your own approved analytics, CRM, and research process where needed. Matches and fields vary. A company match does not identify a person or prove buying intent.
