Company Data

Every company in TheirStack is discovered through job postings. When we collect a job listing, we extract the company behind it and enrich the record with firmographic, financial, and technographic data from multiple sources. The result is a database of 11M companies spanning 238 countries — continuously growing as new companies post jobs.

What's included in each company profile

Each company record can include:

• Firmographics — Name, logo, domain, industry, employee count, headquarters location (city, country), founded year, company description, and LinkedIn profile.

• Financials — Estimated annual revenue, total funding raised, funding stage (from pre-seed to post-IPO), last funding round date, investors, and public market data (stock symbol and exchange).

• Tech stack — Technologies detected from job postings, with confidence scoring. Over 5 million companies have at least one technology mapped.

• Hiring activity — Total historical job count and jobs posted in the last 30 days, giving you real-time signals of growth and hiring urgency.

• Company classification — Whether the company is a direct employer or a recruiting/consulting agency, so you can filter out intermediaries.

How company data grows

Unlike static company databases, TheirStack's company data grows organically. Every time a new company posts a job on any of our 323k sources, it's automatically added to our database and enriched. This means:

• Companies that are actively hiring are always represented.
• The database is biased toward economically active companies — the ones most relevant for sales, recruiting, and market intelligence use cases.
• New companies appear as soon as they start hiring, often before they show up in traditional company databases.
