Firmographic data is the set of attributes that describe a company as a buying entity: industry, size, revenue, geography, ownership, and structure. In B2B, firmographics are the foundation of ICP, segmentation, and account scoring. Without clean firmographics, every downstream targeting decision degrades.
The core attributes
Most firmographic profiles include:
- Identity. Company name, domain, headquarters location, ownership type (public, private, PE-backed, non-profit), parent and subsidiary relationships.
- Size. Employee count (often bucketed and segmented by department), revenue, growth rate.
- Classification. Industry codes (NAICS, SIC), sector, sub-industry. The taxonomies disagree; pick one as primary.
- Operational. Founded year, funding stage and history, public stock ticker if applicable.
A clean firmographic record powers ICP filters (“SaaS companies, 200-1000 employees, North America”), territory routing, and account tiering.
The provider landscape
The market has three groups. Comprehensive databases like ZoomInfo, Apollo, and Cognism own breadth. Specialized providers like Crunchbase (funding), BuiltWith (technographic-adjacent), and PitchBook (private markets) own depth in a slice. Aggregator-and-orchestration tools like Clay sit on top, calling many sources and merging the result.
In practice, the right answer is usually one comprehensive provider as the base, plus one or two specialty sources for the attributes the comprehensive provider gets wrong, plus an orchestration layer to manage the joins.
How firmographics decay
Firmographic data decays at twenty to thirty percent annually. Companies merge, get acquired, rename, change industry, lay off, hire. A target list built on year-old firmographics is significantly wrong. RevOps teams that take this seriously refresh the entire account base monthly or quarterly, not annually.
Common pitfalls
- Trusting one source. Every provider has gaps. Employee counts in particular vary by twenty percent or more across providers for the same company.
- Treating industry as truth. NAICS and SIC codes are coarse and often miscoded. Validate with secondary signals (technographics, job postings) before locking ICP filters.
- Not refreshing. A firmographic snapshot is dated the day you load it. If your routing rules use stale firmographics, deals route to the wrong AE.
