Find Company Data by Website Domain
Company lookup by website means you paste a domain (for example, acme.com) and find a structured company profile back — name, industry, location, headcount, and links like LinkedIn. It's the fastest way to extract "just a website" into usable B2B data.
Perfect for outbound, lead qualification, partner research, and cleaning CRM records. Start with one domain, then scale with Scrupp datasets + enrichment.
Tool first, explanation second — built for quick research and outbound workflows.
Quick answer
How do you look up a company by domain?
A company lookup by domain name takes a website domain (like stripe.com) and returns structured contact information and company data about the business behind it: legal name, LinkedIn URL, industry, headcount, HQ location, tech stack, funding stage, and the names + verified emails of key decision-makers. Scrupp\'s free tool works both as a browser lookup and as a bulk API.
WHOIS lookup vs B2B company lookup — two different jobs
Lots of tools labelled "company lookup by domain" are actually WHOIS tools. A WHOIS lookup queries the WHOIS database (maintained by ICANN-accredited registrars) to find out who owns a domain, when it was registered, when it will expire, and how to use WHOIS for technical ownership records across TLDs. Scrupp returns that WHOIS data plus B2B business context — because the WHOIS registrar record rarely tells you anything useful about the company\'s team, outbound-relevant decision-makers, or how to register a domain for a similar product.
What the Scrupp domain lookup returns
- WHOIS data — registrar, WHOIS contact information where publicly available, domain age, expire date, and free WHOIS privacy flag detection.
- Company data — legal name, LinkedIn company URL, industry, HQ location, headcount.
- Decision-maker contacts — 3-10 key roles per company with verified emails and phone numbers.
- Tech stack — which SaaS tools the company uses, detected from the website and public signals.
Chrome extension works for one-off domain lookups while browsing. The bulk API accepts a list of domains (CSV or JSON) and returns enriched records in minutes — scale from 1 to 100,000 domain queries without a WHOIS database rate limit. The perfect domain lookup flow: search the WHOIS database for ownership, then layer B2B enrichment on top for outbound.
Use our WHOIS lookup tool alongside the B2B enrichment
Use our WHOIS lookup tool to check domain availability, get WHOIS information from the registry, and see registrant contact information where it isn\'t hidden behind domain privacy. The WHOIS lookup tool queries the Internet Corporation for Assigned Names and Numbers (ICANN) registry through accredited registrars — the same source every public WHOIS domain lookup relies on. Privacy protection (domain privacy services) hides the registrant on many domains, but Scrupp falls back to the B2B company data when WHOIS information is redacted.
Check domain availability + get domain name information
- Check domain availability — is the domain registered or available to register? The tool returns availability of a domain across all major TLDs.
- Domain owners and the registrar — who owns the domain, which domain registrar currently handles it, and when domain registration expires.
- Domain name information — creation date, last-update date, and the lookup results in a single JSON response.
- WHOIS domain lookup across TLDs — .com, .io, .ai, .co, .org, country-code TLDs. Full coverage in one request.
A domain lookup tool should answer all of these questions at once. Scrupp\'s hybrid approach merges WHOIS records with B2B company data, so the tool to check a domain\'s status also gives you the marketing / sales context around it. Use the free WHOIS flow for casual checks; upgrade to the API for bulk domain name lookup across lists of 1000+ domains.

How website → company lookup works
A quick guide you can scan in minutes. Use this to understand what "domain enrichment" usually returns.

What you get from a company website lookup
A strong company lookup tool typically returns a standardized profile you can use across sales ops, data enrichment, and outbound campaigns.
Company name, description, industry/category, HQ location, and headcount range.
LinkedIn page, careers page, contact page, and social links to speed up research.
Common stack indicators (CMS, analytics, forms, hosting) for qualification.
Public emails/phones on pages like "Contact", "About", or footer (when available).
Use cases
Turn a list of domains into structured company context before writing messages.
Standardize company fields (industry, location, size) and fill missing links.
Quickly validate who owns a domain and what the company actually does.
Detect mismatched or dead domains before you waste time enriching contacts.
Company lookup → find decision makers on LinkedIn → export → enrich emails/phones → push to CRM.
What makes a "good" domain lookup result?
- Consistent fields (same keys across outputs)
- Clear sources (public site + known profiles like LinkedIn)
- Safe defaults when data is missing (empty/unknown, not guesses)
- CRM-friendly JSON you can map in one step
- Speed for bulk workflows via API
FAQ

Quick answers about company lookup by website and domain enrichment.
What is "company lookup by website"? ▾
It's the process of converting a domain into a structured company record — name, industry, location, headcount, and links like LinkedIn — so you can use it in outbound, research, or CRM enrichment.
