What is firmographic data?
Firmographic data is descriptive information about a company rather than a person, such as industry, employee count, annual revenue, location and years in business. B2B teams use it the way consumer marketers use demographics: to group accounts, build an ideal customer profile and decide which companies to target first.
The word itself is a blend of "firm" and "demographics." Where a B2C marketer segments by age or income, a B2B team segments by company attributes. The term firmographics covers any characteristic you can use to classify an organization: sector, headcount, turnover, geography, structure and maturity.
This data is the raw material of market segmentation in B2B. Get the firmographics right and your targeting, messaging and pricing all line up. Get them wrong and you burn budget pitching the wrong companies. According to Vonsel internal data (2026), restaurants and dentists are the two most-prospected business categories among paying teams, both segments defined first by industry and location.
Key takeaways
Firmographics describe companies, not people: industry, size, revenue, location and age
They power B2B segmentation and the ICP the same way demographics power B2C
Sources include official registries (Census, Eurostat), NAICS codes, directories and verified data providers
Per Vonsel internal data (2026), restaurants and dentists are the top prospected categories, both defined by industry plus location
The variables
The 5 core firmographic variables
Almost every firmographic profile is built from five attributes. Master these before adding anything more exotic:
1
Industry or sector
What the company does, usually coded with a standard like NAICS or its European equivalent. Industry is the single most predictive variable: a dental clinic and a logistics firm have nothing in common as buyers.
2
Company size (headcount)
Employee count separates a solo practice from a 200-person operation. Size drives budget, buying process and the seniority of the person you need to reach.
3
Annual revenue
Turnover signals spending power and deal size. Pairing revenue with headcount reveals efficiency: high revenue per employee often means a more sophisticated buyer.
4
Geographic location
Country, region and city define your serviceable market, language, currency and compliance regime. For field sales it also decides routing. This is why teams segment companies by size, industry and location together.
5
Company age (years in business)
A newly funded startup and a 30-year-old family business buy very differently. Age, plus signals like funding stage and growth rate, tells you where a company is in its lifecycle.
Filter the whole market by firmographics
Search millions of verified businesses by industry, size and location, then export the ones that match your profile, no manual list building.
The fastest way to understand firmographics is to contrast them with demographic data, the consumer attributes most people already know:
Dimension
Demographic data (B2C)
Firmographic data (B2B)
Unit described
An individual person
An organization
Typical variables
Age, gender, income, job title, education
Industry, headcount, revenue, location, age
Buying unit
One consumer
A buying committee inside a company
Used for
B2C segmentation and ad targeting
B2B segmentation, ICP and account targeting
Main sources
Surveys, census, platform data
Registries, NAICS, directories, B2B providers
The two are not rivals. In B2B you often combine them: firmographics pick the right company, then demographics (the contact's role and seniority) pick the right person inside it.
Firmographics answer the only question that matters before outreach: is this even the right kind of company to be talking to? Everything else, the email, the call, the demo, is wasted if that answer is no.

In practice
How to use firmographic data for ICP and segmentation
Firmographics are not a vanity field in your CRM. They drive two of the highest-leverage decisions in B2B: who your best-fit accounts are, and how you split the market to reach them.
Build the ICP
Your ideal customer profile is mostly firmographics: which industries, sizes, revenue bands and regions describe your best customers.
Size the market
Count how many companies match each firmographic filter to estimate your total addressable market before you commit budget.
Segment and tailor
Split the market into tight segments (sector plus size plus city) so each one gets a relevant offer, price and message instead of one generic blast.
Enrich and score
Append missing firmographics through B2B data enrichment, then score leads on fit so reps work the best accounts first.
Where does the data come from? Official statistics offices such as the US Census Bureau's County Business Patterns and Eurostat business demography statistics publish industry and size breakdowns, while business directories, map data and B2B providers turn them into account-level records. The catch: firmographics decay fast, so freshness matters as much as coverage, and as HubSpot's sales research shows, reps already lose a large share of their day to research instead of selling.
Demographics tell you which person to call. Firmographics tell you whether their company was ever worth calling.
How Vonsel helps
How Vonsel turns firmographics into a target list
Vonsel's Business Finder lets you filter millions of verified businesses across 120+ countries by the exact firmographics that define your ICP: industry, company size, location and more. Search "dental clinics in Madrid" or "logistics firms in Texas" and get every matching company with name, address, phone, website, Google rating and a verified email, at 85-95% email accuracy and 90%+ phone accuracy, GDPR compliant. Instead of stitching firmographic data together from registries by hand, you go straight from a filter to an exportable, segmented list. Plans on the pricing page start at $23.95/month, and you get 20 verified leads when you start the free trial.
In short:
Firmographics describe companies (industry, size, revenue, location, age), not people.
They define your ICP and drive every meaningful B2B segment.
Vonsel lets you filter the whole market by those variables and export a ready list.

Firmographic data is descriptive information about a company rather than a person, such as industry, employee count, annual revenue, location and years in business. B2B teams use it the way consumer marketers use demographics: to group accounts, build an ideal customer profile and decide who to target.
What are the main firmographic variables?
The five core firmographic variables are industry or sector, company size (employee headcount), annual revenue, geographic location, and company age or years in business. Many teams add status signals such as funding stage, growth rate and technologies used for a richer profile.
What is the difference between firmographic and demographic data?
Demographic data describes individual people (age, gender, income, job title), while firmographic data describes organizations (industry, headcount, revenue, location). Demographics drive B2C segmentation; firmographics drive B2B segmentation, where the buying unit is a company, not a single consumer.
How is firmographic data used for segmentation?
You filter your market by firmographic variables (for example, dental clinics with under 20 employees in a given city) to create tight segments. Each segment shares pains and budgets, so you can tailor the offer, the pricing and the message instead of sending one generic pitch to everyone.
Where does firmographic data come from?
Sources include official business registries and statistics offices (Census Bureau, Eurostat, national statistics institutes), industry classification systems like NAICS, public company filings, business directories, map and web data, and B2B data providers that verify and combine these inputs.
Why is firmographic data important for an ICP?
An ideal customer profile is defined almost entirely by firmographics: which industries, sizes, revenue bands and regions describe your best-fit accounts. Without firmographic data you cannot measure how many companies match your ICP or build a target list that reflects it.
Is firmographic data the same as technographic data?
No. Firmographic data describes the company itself (industry, size, revenue, location). Technographic data describes the software and technologies a company uses. They are complementary: firmographics tell you who fits, technographics tell you what stack they run.
