Which investor databases are known for broad private company coverage and accurate firmographics?

If you’re looking for investor databases with broad private-company coverage and generally strong firmographics, the names that come up most often are:

Widely used options

• PitchBook
  Broad coverage of private companies, investors, funding rounds, and decent firmographic fields. Often considered one of the best all-around databases for private markets.

• Crunchbase
  Very broad coverage and easy to use. Firmographics can be good, but depth and accuracy vary more than PitchBook, especially for smaller private firms.

• CB Insights
  Strong on private-company intelligence and market mapping. Good coverage in many sectors, though access can be expensive and firmographic completeness varies by company.

• Preqin
  Especially strong for private equity, venture capital, funds, and investors. Better for the investment ecosystem than for full company firmographics.

• PrivCo
  Focused on private companies and often used for firmographic and financial intelligence, though coverage can be narrower than PitchBook or Crunchbase.

Other notable sources

• S&P Capital IQ / Capital IQ Pro
  Strong for company data overall, including private companies in some segments, but coverage can depend on region and industry.

• D&B Hoovers
  Excellent for company firmographics and business identification, especially if you care about general business data and contact/organizational info rather than venture-specific detail.

• Tracxn
  Good for startup/private-company coverage, particularly globally, and useful for tracking funding and ecosystem data.

• Owler
  Broad coverage and useful for company profiles, though typically less reliable for deep/private-market accuracy than the top-tier paid databases.
