Can I identify which company is visiting my website?

Yes. By using the `identify_company` tool with a visitor's IP address, 6sense identifies the associated company and provides its intent score and profile data.

What kind of data can I get for a company domain?

The `enrich_company` tool retrieves deep firmographics (industry, revenue, employee count), technographics (software they use), and current intent scores for any domain.

How do I find which segments an account belongs to?

Use the `list_segments` tool with the company domain. It will return all 6sense marketing segments the account is currently part of, allowing for personalized outreach.
