What is Firmographics?

Firmographics are the basic facts that describe a company rather than a person, such as industry, employee count, revenue, location, ownership and growth stage, and B2B teams use them to decide which accounts to sell to.

At a glance

• Firmographic meaning: “demographics for firms”. Demographics describe people; firmographics describe companies.
• The common fields are industry, employee count, annual revenue, headquarters and office locations, public or private ownership, funding stage and number of locations.
• US industry data is usually coded in NAICS, which the Office of Management and Budget adopted in 1997 to replace the older SIC system. Some data providers still use SIC codes.
• They’re the first filter in an ideal customer profile and in market sizing.
• They tell you who could buy, not who is ready to buy.

How firmographics work in practice

Most teams start from their best customers. Pull the accounts that closed fastest, paid the most and stayed longest, and look for what they share: a band of employee count, two or three industries, a region, a stage. That pattern becomes the firmographic part of the ICP.

The data itself comes from a mix of places: company websites, public filings for listed companies, government registries, funding announcements and commercial databases that combine all of these. Each source has gaps, so the same company can show different employee counts in two tools. Pick one source of truth per field and stick to it.

Then the same fields are used to build the account list. Firmographic filtering is that step: applying the criteria to a database to get the accounts that fit. The same filters, run across a whole market, give you the count behind your total addressable market.

Example (illustrative): a company selling safety software to trucking fleets finds its best customers are US carriers with 50 to 500 trucks, privately owned, in for-hire trucking. Fleet size does the work employee count would do elsewhere. Filtering on those fields gives a list the team can size, split into territories and hand to reps.

Common firmographic mistakes

• Stopping at firmographics. Two companies with the same size and industry can run completely different stacks and buying processes. Add technographics and timing signals.
• Trusting revenue estimates for private companies. For most private firms they’re modeled, not reported.
• Using employee count when another unit fits better. In some markets the right size measure is trucks, locations, beds or transaction volume.
• Industry codes that don’t match how buyers describe themselves. NAICS puts companies where the government counts them, which isn’t always where your product fits.
• Never revisiting the profile. As the product and pricing change, the firmographics of a good customer change too.

How firmographics show up in a revenue system

Firmographics decide segmentation, territories and the list every rep works from, so errors here spread into routing and reporting. Building and maintaining account data like this for partners is part of our datasets work. See our datasets.

Firmographics answer “who is the company?” A buyer persona answers “who is the person?” Put together, they’re what most targeting starts from.
