What is Firmographic Data?
Definition: Company-level attributes such as industry, employee count, revenue, founding year, headquarters location, and funding stage that help qualify whether a business fits your ideal customer profile.
Firmographic data is to companies what demographic data is to people. It describes the characteristics of a business: how big it is, what industry it's in, where it's headquartered, how much revenue it generates, and what stage of funding it's at. GTM Engineers use firmographics to filter target account lists and prioritize outreach.
The core firmographic data points: employee count (is this a 10-person startup or a 5,000-person enterprise?), revenue (can they afford your product?), industry (SaaS, healthcare, fintech?), location (is your sales team set up to sell into EMEA?), and funding stage (Seed companies have different budgets than Series C).
Clearbit (now part of HubSpot) is the default firmographic enrichment source for many teams. It auto-populates company records in your CRM with industry classification, employee ranges, and tech stack data. Apollo and ZoomInfo also provide firmographics alongside contact data.
In a Clay workflow, you typically enrich with firmographics first, then filter. Grab 1,000 companies from a LinkedIn search, enrich with Clearbit for employee count and industry, filter down to SaaS companies with 50-500 employees, then look up contacts at the surviving companies. This front-loading saves enrichment credits because you don't waste contact lookups on companies that don't fit your ICP.
