Key takeaways
- Firmographics describe company characteristics such as industry, size and location.
- Definitions and entity scope matter when comparing fields across sources.
- Use firmographics for segmentation while preserving unknowns and business context.
Overview
Firmographics provide a common starting point for an ICP, territory or market estimate. The fields need definitions: “size” might mean employees, locations or revenue, and each produces a different segment. Industry classifications also vary. Retain the classification system and observation date so records remain comparable across sources and reporting periods.
How it works
Select company attributes that reflect the business question.
Normalize units, ranges and classification systems across sources.
Apply segment rules while retaining unknown and estimated values.
Define each attribute before filtering
A filter for “companies with 100 to 500 employees” appears simple until one source reports global headcount and another reports a local entity. The same issue affects revenue, location and industry. Write down the field definition and the account boundary so a segment can be reproduced by another person or system.
Classification systems also differ. NAICS is a North American industry classification system published through official statistical agencies; a vendor’s custom industry taxonomy may use different boundaries. Preserve the original code and version where relevant, then map to your internal labels explicitly. A broad mapping can be useful without implying that the categories are exact equivalents.
| Field | Qualifier to preserve | Segmentation implication |
|---|---|---|
| Industry | Taxonomy, code and activity scope | Different systems can group companies differently |
| Employee count | Entity scope and observation date | Thresholds can shift when estimates change |
| Revenue | Currency, period and estimation method | Values may not be directly comparable |
| Geography | Headquarters versus operating presence | Territory eligibility depends on the chosen meaning |

Use firmographics as a starting filter
Firmographics help narrow a market, but they rarely explain the whole buying problem. Two logistics companies of the same size may have different systems, customer types and operating models. Combine descriptive filters with evidence of the relevant workflow or need instead of assuming that a shared industry label creates a shared purchase reason.
Keep hard constraints separate from preferences. A supported geography may be mandatory; a preferred size band may be a prioritization choice. Missing revenue should remain unknown unless the workflow has a documented rule for handling it. Treating missing values as zero can systematically exclude companies with less public financial information.
Check how fragile the segment is
An illustrative segment contains 800 companies at a 100-employee minimum. Lowering the threshold to 80 adds 250 accounts, many close to the original cutoff. Review whether those added accounts differ meaningfully in problem fit. If small changes to an uncertain estimate dramatically alter the market, the threshold may be creating false precision.
Version the filters and record when the underlying fields were observed. A quarter-over-quarter increase in eligible accounts can come from a source refresh rather than real market growth. Report those changes alongside the segment count and review representative inclusions and exclusions before using the result for territory planning or market-size estimates.
What this looks like in practice
A team targets manufacturers with 100–1,000 employees in Ontario. It specifies the industry classification used and flags companies whose employee ranges overlap the threshold instead of claiming exact eligibility.
Examples explain the concept; they are not reported customer results.What to check
Check classification consistency, entity scope and how estimated ranges affect filters. Reconcile parent-company attributes with the account unit your team sells to.
Common mistake
Mixing revenue in different currencies or employee counts from different dates without normalization or source context.
Firmographic data vs. Technographic data
Firmographics describe the organization. Technographics describe technologies it uses or is observed using. Both can inform fit, but they answer different questions.

What is Firmographic data?
Firmographic data describes organizations through attributes such as industry, size, location, ownership and revenue range, helping teams segment businesses and evaluate company-level fit.
Are industry codes universal?
No. Systems such as NAICS use specific definitions and versions. Map codes deliberately when combining datasets rather than assuming similarly named categories are equivalent.
Can firmographics prove buying intent?
No. They describe fit and context. A company can match every firmographic criterion without currently evaluating a purchase.
Are firmographics the B2B equivalent of demographics?
That analogy is often useful: firmographics describe organizations rather than people. It is still important to define each field precisely. Company structure, multiple locations and changing ownership create relationships that a simple demographic analogy does not fully capture.
How often do firmographic fields change?
It depends on the field and company. An industry classification may remain stable while headcount, revenue period or operating locations change. Use observation dates and refresh rules that fit the decision. There is no single decay percentage that safely describes every firmographic field or source.
