Entity resolution determines whether records refer to the same real-world business.

## Why it matters

Avoid sending research to the wrong company account.

## Illustrative example

A workflow checks whether a brand domain and CRM record describe the same organization.

## What to check

Similar names are not enough to establish identity.

## 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.
