Firmographics: what they are, examples, and what they miss
Updated By the SalesOne research team8 min read
The short answer
Firmographics are the basic facts about a company that B2B teams use to define and filter targets: industry, employees, revenue, location, ownership and age. They tell you whether a company could buy from you. They do not tell you whether it needs to buy now; that takes technographic data, intent data or dated buying signals.
What are firmographics?
Firmographics are to companies what demographics are to people: the descriptive facts, such as industry, size and location, that let you group companies and decide which ones fit.
| Field | Example | Typical source | Watch out for |
|---|---|---|---|
| Industry | Metal castings manufacturer | Industry codes such as NAICS, the company’s own site | Codes describe the main activity, not every product line |
| Employees | About 420 | Company site, filings, data providers | Estimates vary widely between sources |
| Revenue | Private, not disclosed | Filings for public companies; estimates otherwise | Most private-company revenue is a guess |
| Location | Headquarters in Toledo, Ohio | Company site, business registries | Headquarters is not where every decision is made |
| Ownership | Privately owned | Filings, press releases, investor portfolio pages | Changes after acquisitions and often lags in databases |
| Age | Founded decades ago | Business registries, company history page | Rarely matters on its own |
Record each field with its source and the year it refers to. A size figure without a year cannot be checked, and a figure from five years ago may describe a different company.
What is the difference between firmographic and technographic data?
Firmographic data describes what a company is; technographic data describes the software and systems it uses. Intent data and buying signals describe what it is doing or reading now.
| Data | Answers | Example | Changes |
|---|---|---|---|
| Firmographic | Could this company buy? | A 420-person manufacturer in Ohio | Slowly |
| Technographic | What does it run today? | Uses a specific ERP system | Occasionally |
| Intent | Is someone there reading about the topic? | Spike in reading about plant layout | Weekly |
| Buying signal | Did something change that creates the problem now? | A permit for a new site, dated | At a known date |
Our guide to intent data explains how topic signals are collected and where they mislead, and signal-based selling covers working from dated events.
What is the difference between firmographics and demographics?
Demographics describe people, such as age, role or income; firmographics describe organizations. B2B teams use firmographics to choose companies and role data to choose the people inside them.
How do you use firmographics to define your target market?
Use firmographics as the first filter in your ideal customer profile: write each field as a rule that can be checked, then count how many companies pass.
| Field | Weak rule | Checkable rule |
|---|---|---|
| Industry | “Manufacturing” | Makes metal castings or machined parts, from the company’s own site |
| Size | “Mid-market” | 100 to 1,000 employees, with a source and a year |
| Ownership | “Not too corporate” | Privately owned or owner-managed; not a subsidiary that buys through a parent |
| Location | “US” | Headquarters or a plant within a day’s travel of our team |
The count that passes is your serviceable market; our guide to TAM, SAM and SOM shows how to size it, and the ideal customer profile guide shows how to write the full set of rules.
Where does firmographic data come from?
Firmographic data comes from public records, company websites and data providers that combine them. Public records are slower but checkable; providers are fast but often estimate.
- Official statistics, such as the US Census Bureau’s County Business Patterns, count establishments by industry and size, which is useful for market sizing but does not name companies.
- Filings and registries, such as SEC filings for public companies and state business registries, give legal names, ownership and officers.
- Company websites and press releases give what the company makes, its sites and its leaders, in its own words.
- Data providers combine these into searchable databases; ask each one where a field came from and when it was last checked.
What are the limits of firmographic data?
Firmographics go stale, mix up sites and companies, and say nothing about timing. A company can fit every rule and still have no reason to talk to you this year.
- Estimates. Employee and revenue figures for private companies are often modelled, not reported.
- Staleness. Ownership changes and headcount shifts can take months to reach a database.
- Sites versus companies. A plant can look like a separate company, or a company can hide behind its parent.
- No timing. Firmographics show fit, never urgency, which is why a list built from filters alone needs a reason to contact each company.
What do firmographics and buying signals look like together?
Here is one fictional account seen two ways: firmographics show it fits, and dated signals show why now.
| Kind | Fact | What it tells the seller |
|---|---|---|
| Firmographic | Metal castings manufacturer, about 420 employees, privately owned, Toledo, Ohio | Fits the profile |
| Buying signal | Ruth Adeyemi named COO, press release dated Aug 25, 2026 | A new leader setting priorities |
| Buying signal | County permit dated Sep 12, 2026 for a 140,000 sq ft foundry expansion in Dayton | A new site to plan, staff and equip |
The firmographic row alone would put Halvorsen on a list with thousands of similar companies. The two dated signals put it at the top, with the first line of the message already written.
How does SalesOne use firmographics?
SalesOne is AI account research and qualification for B2B teams. In account research, S1 agents check each company’s size, ownership and location with a source and a year, then look for dated buying signals before keeping or rejecting it with a reason.
In SalesOne’s production research runs in October 2026, 249 of 1,051 companies checked were kept, and all 802 rejected companies keep their reason; 88% of those reasons contain a date.
