How to Enrich a Company Domain: Complete Guide with 30+ Attributes (2026)

Company domain enrichment is the process of transforming a basic domain name (like "acme.com") into comprehensive firmographic and technographic data—industry, revenue, employee count, technology stack, and 30+ other attributes—using enrichment APIs and databases. According to SMARTe's 2026 Clearbit analysis, modern enrichment tools can append 100+ data points from just a domain input. This guide covers how to enrich company domains with detailed attributes in 2026.

What Is Company Domain Enrichment?

Company domain enrichment transforms a simple website address into a detailed company profile. When you input a domain like "salesforce.com" into an enrichment API, you receive structured data including company name, industry, employee count, annual revenue, headquarters location, technology stack, funding history, and social profiles.

At Enricher.io, we process millions of domain enrichment requests annually, and the value proposition is straightforward: instead of manually researching each prospect company, enrichment APIs return comprehensive profiles in milliseconds. A sales rep can paste a domain into their CRM and instantly see everything they need for qualification and outreach.

The technical process works through matching algorithms that cross-reference the domain against multiple data sources—company databases, public filings, social profiles, web scraping, and third-party data providers. The result is a unified company profile with verified, up-to-date information.

What Data Can You Get from a Company Domain?

Modern enrichment APIs return extensive data from a single domain input. Here are the key attribute categories:

Firmographic Attributes

Firmographics describe the company's basic characteristics:

Technographic Attributes

Technographics reveal what tools and software the company uses:

Contact and Social Attributes

Advanced Attributes

According to Cognism's 2026 API comparison, leading providers like Coresignal offer 300+ data points per company profile, including workforce analytics, funding history, online presence metrics, and customer reviews.

How Does Company Domain Enrichment Work?

Company domain enrichment follows a straightforward technical process:

1. Input the Domain: Provide a company domain (e.g., "stripe.com") to the enrichment API via direct API call, CSV upload, or CRM integration.
2. Identity Resolution: The enrichment service matches the domain against its database of companies, resolving variations (www.stripe.com, stripe.co, etc.) to a single company entity.
3. Data Aggregation: The service pulls data from multiple sources—company databases, public records, web scraping, third-party providers—and consolidates it into a unified profile.
4. Data Return: The API returns structured JSON containing all available attributes, typically within milliseconds for real-time requests.
5. CRM Integration: The enriched data populates your CRM, marketing automation, or data platform automatically.

API Implementation Example

Here's a typical API request structure for company domain enrichment:

import requests

API_KEY = "your_api_key"
DOMAIN = "enricher.io"

response = requests.get(
    "https://api.enricher.io/v1/company",
    params={"domain": DOMAIN},
    headers={"Authorization": f"Bearer {API_KEY}"}
)

company_data = response.json()
print(company_data)

The response typically includes all available firmographic, technographic, and contact attributes in structured JSON format that can be parsed and stored in your systems.

How Do You Choose a Domain Enrichment Tool?

Select your enrichment provider based on your specific use case:

What Are the Best Practices for Company Domain Enrichment?

Based on implementing domain enrichment for hundreds of organizations, here are the practices that maximize value:

1. Validate Domains Before Enrichment

Enrichment APIs charge per lookup. Before enriching, validate that domains are:

• Properly formatted (remove protocols, paths)
• Not personal email domains (gmail.com, yahoo.com)
• Not parked or expired domains
• Deduplicated (don't enrich the same domain twice)

2. Use Waterfall Enrichment for Maximum Coverage

No single provider has 100% coverage. According to Sparkle's 2026 analysis, waterfall enrichment—querying multiple providers sequentially—significantly improves match rates. Query your primary provider first, then fall back to secondary providers for unmatched domains.

3. Implement Real-Time Enrichment on Form Submissions

Enrich company data the moment a lead submits a form containing a work email address. This enables:

• Instant lead qualification and scoring
• Automatic territory routing
• Personalized follow-up messaging
• Shortened forms (collect email, enrich the rest)

4. Schedule Regular Data Refresh Cycles

Company data changes over time—headcount grows, companies get acquired, technology stacks evolve. According to SMARTe's research, leading providers refresh records every 30 days. Implement quarterly re-enrichment of your existing accounts to catch changes.

5. Map Enriched Data to ICP Scoring

Connect firmographic attributes directly to your Ideal Customer Profile (ICP) scoring:

• Industry matches target vertical: +20 points
• Employee count in range (50-500): +15 points
• Uses competitor technology: +25 points
• Located in target geography: +10 points
• Recent funding round: +20 points

Key Takeaways

• Company domain enrichment transforms a simple domain into comprehensive firmographic and technographic profiles—industry, revenue, employee count, technology stack, and 30+ other attributes
• Modern enrichment APIs return 100-300+ data points from a single domain input, eliminating manual research and enabling instant lead qualification
• Key attribute categories include firmographics (industry, size, revenue), technographics (software stack), and contact data (phone, social profiles)
• Clearbit is now HubSpot-only (Breeze Intelligence)—standalone users should evaluate Enricher.io, ZoomInfo, or CompanyEnrich
• Use waterfall enrichment (multiple providers) to maximize coverage beyond what any single provider offers
• Implement real-time enrichment on form submissions to enable instant lead scoring and territory routing

Frequently Asked Questions

What is company domain enrichment?

Company domain enrichment is the process of transforming a basic domain name (like "acme.com") into comprehensive company data—industry, employee count, revenue, technology stack, location, social profiles, and other firmographic and technographic attributes. Enrichment APIs match the domain against company databases and return structured data.

How many attributes can you get from a company domain?

Depending on the enrichment provider, you can get 17 to 300+ attributes from a single domain. Basic providers return core firmographics (industry, size, location). Enterprise providers like ZoomInfo and Coresignal return extensive data including technographics, intent signals, workforce analytics, and funding history.

What is the difference between firmographic and technographic data?

Firmographic data describes company characteristics—industry, employee count, revenue, location, founding year, and company type. Technographic data describes the company's technology stack—what CRM, marketing tools, cloud infrastructure, and other software they use. Both are valuable for B2B targeting and qualification.

How much does company domain enrichment cost?

Pricing varies by provider and volume. Affordable options like Hunter.io start at $49/month. Mid-market platforms like Enricher.io and CompanyEnrich offer per-lookup pricing or plans starting around $279/month. Enterprise solutions like ZoomInfo typically require $15,000+/year commitments with custom pricing.

How do I enrich company domains in bulk?

Most enrichment providers offer bulk processing via CSV upload or batch API endpoints. Upload a CSV containing domain names, and the service returns a file with all enriched attributes appended. For ongoing enrichment, integrate the API directly with your CRM or data platform.

Can I enrich personal email domains?

No. Company domain enrichment only works with business domains (acme.com, enricher.io). Personal email domains (gmail.com, yahoo.com, outlook.com) cannot be enriched to company data because they don't represent specific organizations. Filter out personal domains before enrichment to avoid wasted API calls.
