Enrich Company Data: Add Firmographics, Domains, and Better Account Fields

Company data enrichment fills the account-level fields that contact-level enrichment alone doesn't cover: company headcount, revenue range, industry vertical, technology stack, headquarters location, funding status, and the company domain that serves as the primary lookup key for everything else.

These fields matter beyond individual outreach. Company size drives ICP qualification. Industry enables vertical-specific messaging. Revenue range separates enterprise from mid-market from SMB targeting. Without these fields, you can reach contacts but you can't segment, personalize by account type, or build accurate pipeline reporting.

This guide covers how company data enrichment works, which firmographic fields to prioritize, and how to integrate company enrichment into your standard lead list or CRM workflow.

Company enrichment and contact enrichment serve different purposes but work best when run together. Contact enrichment gives you the reach capability. Company enrichment gives you the targeting intelligence. Without both, you risk reaching the right person at the wrong account or the wrong person at the right account.

Why Company Data Enrichment Matters Separately from Contact Enrichment

Contact enrichment fills person-level fields: email, job title, phone number, LinkedIn profile. Company enrichment fills account-level fields: headcount, revenue, industry, domain, funding, technologies used. Both are necessary for a complete B2B record, but they answer different questions.

Contact data tells you how to reach someone. Company data tells you whether their company is the right target. A VP of Sales at a 5-person startup and a VP of Sales at a 500-person company have the same title but completely different buying contexts — you can't address them the same way. Company enrichment is what makes differentiated, account-aware outreach possible.

Key Company Fields to Enrich

• Company domain: the single most important field — it's the lookup key for all other company enrichment and for email address pattern lookup
• Company headcount (employee count): the primary ICP firmographic for most B2B products
• Revenue range: enterprise vs. mid-market vs. SMB segmentation
• Industry (and sub-industry): vertical-specific messaging and targeting
• Headquarters location: geography-based segmentation and territory assignment
• Technology stack: for tools that enrich technology usage (useful for tech-stack-targeted outreach)
• Funding status and round: useful for startups where growth stage affects buying context
• LinkedIn company page URL: for account-based social selling
• Founded year: company maturity context

Step 1: Upload or Import Your CSV

Start with your account or contact list. For company enrichment, the most useful input is a company domain. If you have company names but not domains, you can derive domains through a first-pass enrichment step specifically for domain lookup, then run company enrichment using the returned domains.

Step 2: Detect Which Company Fields Are Missing

Audit the company-level columns in your file. Common gaps: no company domain (only company name), no headcount, no industry, no revenue. Knowing exactly what's missing shapes which enrichment fields to request. If you have headcount but not industry, request industry only — don't re-request fields already populated.

Step 3: Normalize and Clean Company Name and Domain Fields

Before enrichment, clean company names: standardize capitalization, remove common suffixes that vary (Inc, LLC, Corp) if they create inconsistent matches, and remove leading/trailing spaces. Clean domains: strip http://, www., and URL paths. These cleaning steps directly improve match rates.

Step 4: Enrich Company Data

Upload the cleaned file to your enrichment tool. Map the company domain column and request the firmographic fields you need. The tool returns company size, industry, revenue range, and other available fields for each matched company. Companies without matches in the database return empty or low-confidence fields.

Step 5: Review Confidence and Quality

Company-level enrichment is generally more stable than contact-level enrichment — headcount and industry don't change as frequently as an individual's email address or job title. That said, company size can be significantly off for fast-growing or recently downsized companies, and industry classification varies across data providers.

Apply your confidence threshold and spot-check a sample. For high-value accounts, verify company size against LinkedIn company page or the company's own website — the number shown there is typically current and authoritative.

Step 6: Fix Bad Rows

• Remove companies where enriched size is far outside your ICP range
• Remove companies where enriched industry doesn't match your target verticals
• Flag companies where domain enrichment returned a mismatch (domain doesn't look like it belongs to the company name)
• Merge rows where the same company appears multiple times with different contact records — keep the same company data fields consistent across all contacts at the same account

Step 7: Export and Use Enriched Company Data

Export the enriched file. In your CRM or sequencer, use the enriched company fields for segmentation: separate lists by company size range, by industry, by geography. Use enriched company data for account-level scoring and prioritization in your outreach planning.
