Company Enrichment

Give it a domain. Get back a company profile assembled from public records.

No API keys, no logins, no personal data. Every field comes from somewhere anyone can look: domain registration records, DNS, the company's own public homepage, and public certificate logs.

What you get

One row per domain:

Identity

Field	Description
domain	Normalised domain (protocol and www. stripped)
companyName	Company name from site metadata
description	Meta or OpenGraph description
title	Page title
language	Declared page language

Registration — from RDAP, the public successor to WHOIS

Field	Description
registrar	Who the domain is registered through
registeredAt / expiresAt	Registration dates
domainAgeYears	Age in years — a useful proxy for company maturity
status	Domain status codes

Infrastructure — from DNS

Field	Description
mailProvider	Google Workspace, Microsoft 365, Zoho, Proton, Mimecast, Fastmail, Amazon SES
nameserverProvider	Cloudflare, AWS Route 53, Azure, Google
mx / ns / ipv4	Raw records
hasSPF / hasDMARC	Email authentication posture

Technology and presence — from the public homepage

Field	Description
technologies	Detected stack: WordPress, Shopify, Next.js, HubSpot, Segment, Intercom, Stripe and more
socials	LinkedIn, X, GitHub, YouTube handles found on the page
atsPlatform / atsSlug	Which hiring system they use, and their slug
careersLinkInHtml / pricingLinkInHtml	Whether those links appear in the static HTML

Input

{
  "domains": ["stripe.com", "notion.so", "figma.com"],
  "includeHomepage": true,
  "includeCertificates": false,
  "timeoutSeconds": 25
}

Option	Default	What it does
domains	required	Domains to enrich. https:// and www. are stripped for you
includeHomepage	true	Read the public homepage for metadata, tech and socials
includeCertificates	false	Look up subdomains in public certificate logs. Off by default because the crt.sh service is often slow
timeoutSeconds	25	Per-domain timeout

Who this is for

• Sales teams qualifying inbound domains before a rep spends time on them
• Marketing segmenting a list by technology stack or company maturity
• Investors doing quick diligence across many companies at once
• Recruiters — the atsPlatform field tells you exactly where a company posts its jobs
• Security and IT auditing email authentication (SPF/DMARC) across a portfolio

Pairs naturally with our ATS Jobs Aggregator: this tells you a company uses Greenhouse and gives you their slug; that one pulls all their open roles.

Where the data comes from

Source	What it provides
RDAP	Registration, registrar, dates
DNS	MX, NS, A records, SPF, DMARC
Public homepage	Metadata, technology signals, social links
Certificate transparency logs	Subdomains (optional)

The homepage fetch honours robots.txt — a site that disallows crawling is skipped, and the row comes back with robotsAllowed: false.

Honest limits

• Technology detection reads static HTML only. Sites that load everything client-side will show fewer signals. Detection matches asset URLs, not brand names, so a company merely mentioning Shopify is not reported as using it.
• careersLinkInHtml is about the HTML, not reality. Sites with client-rendered navigation will report false even when the page exists. The field name says so deliberately.
• includeCertificates adds roughly 8 seconds per domain and sometimes returns nothing when crt.sh is unavailable.
• No personal contact data is collected. This profiles companies, not people.

Pricing

Pay per event. You are charged per domain successfully enriched.
