Domain Enrichment: Find the Company Behind Any Website
Domain enrichment turns a website or email domain into a lead. Paste the URL of a prospect, an inbound signup or a competitor's customer and get the registered company behind it: legal name, registration number, industry, size, CEO, corporate group and whether we hold phone and email. Verified against 374M+ companies in official registers, not a WHOIS record.
See the company behind any page while you browse. 10 free lookups, no account needed.

Domain enrichment: from website to lead in one step
A domain or WHOIS tool tells you who registered a name, which is useless for sales. We find the business operating the site and return the registry data your pipeline needs, for one website here or for thousands through the API.
What a domain lookup gives you
- A registrar, name servers and dates
- A registrant that is usually redacted
- No company, no size, no decision maker
- Nothing you can qualify or call
What you get as a lead
- Registered company, trade name and registration number
- Industry, employees, founding year and status
- CEO or director and the corporate group
- Phone and email in the full report and API

Frequently asked questions
What is domain enrichment?
Domain enrichment takes a website or email domain and returns the company behind it. Paste the website above. We identify the registered company operating it and show the data a lead needs: legal name, registration number, industry, size, CEO and corporate group. Open the full company report to see phone, email and every location, or enrich a whole list of websites through the API.
What data do I get for a website?
Registered company name and trade name, registration number (KVK, Companies House, Handelsregister and 200+ other registers), VAT number, legal form and status, address, industry codes, employee count, founding year, CEO or director, and the corporate group it belongs to. Phone and email are available in the full report and through the API.
Can I enrich a list of websites or domains in bulk?
Yes. The domain enrichment endpoint of the CompanyData API downloads a page, extracts the registration numbers and legal names it finds and lets you resolve them against 374M+ companies. Point it at your CRM's website field or a list of domains and enrich them all. See the API documentation for /api/website/html.
Is this a WHOIS or domain owner lookup?
No. WHOIS tells you who registered the domain name, which since GDPR is usually a privacy service. We identify the company that operates the website and return its registry data, which is what you need to qualify, contact or verify it.
Is there a browser extension?
Yes. The free Who Owns This Website? Chrome extension shows the company behind the page you are on, with its registration data and a link to the full report. The first 10 lookups are free; after that you continue with your own API key.
Which countries are covered?
Company data comes from 200+ official trade registers worldwide, including the Dutch KVK, UK Companies House and German Handelsregister, covering 374M+ companies.
