Companies

Accepted values, code references, and units for the company-level filters in Company Search and Find People — company.type, company.employee_range, company.naics_code, company.sic_code, company.revenue, company.web_traffic, company.ad_spend, and the funding filters (company.total_funding, company.last_funding_amount, company.last_funding_year, company.last_funding_type, company.lead_investors).

​
Employee Range

Used in: Company Search, Find People (company.employee_range filter)

​
Company Type

Used in: Company Search, Find People (company.type.include and company.type.exclude filters).
  • "Educational"
  • "Educational Institution"
  • "Government Agency"
  • "Nonprofit"
  • "Partnership"
  • "Privately Held"
  • "Public Company"
  • "Self-Employed"
  • "Self-Owned"
  • "Sole Proprietorship"

​
NAICS Code

Used in: Company Search, Find People (company.naics_code.include and company.naics_code.exclude filters). NAICS (North American Industry Classification System) codes are 2–6 digit strings maintained by the US Census Bureau. Codes are matched exactly as strings — a 6-digit query ("541511") will not match a company stored at the 4-digit parent ("5415") or vice versa. Use the most specific code you have. Browse the full catalog at census.gov/naics.

​
SIC Code

Used in: Company Search, Find People (company.sic_code.include and company.sic_code.exclude filters). SIC (Standard Industrial Classification) codes are 4-digit strings — the older US classification still widely used by the SEC and credit databases. Like NAICS, matches are exact strings with no implicit prefix expansion. Browse the full catalog at osha.gov/sic-manual.

​
Revenue, Web Traffic, Ad Spend

Used in: Company Search, Find People (company.revenue, company.web_traffic, company.ad_spend filters). These three filters share the same { min, max } shape. Pass 0 for either bound to leave it open — { min: 1_000_000, max: 0 } means “at least 1M, no upper limit”.
revenue is matched as a range intersection: a company stored with the band [5M, 50M] matches a query of { min: 10M, max: 20M }. web_traffic and ad_spend are matched as point ranges against the latest known monthly value.
Many companies have no public revenue, traffic, or ad-spend signal. Applying these filters narrows results aggressively — combine with a broad industry or naics_code rather than a strict linkedin_url list.

​
Funding

Used in: Company Search, Find People (company.total_funding, company.last_funding_amount, company.last_funding_year, company.last_funding_type, company.lead_investors filters). Qualify accounts by their fundraising history. The amount and year filters share the { min, max } range shape — pass 0 on either bound to leave it open. last_funding_type and lead_investors use the { include, exclude } shape.

​
Last Funding Type

last_funding_type.include and last_funding_type.exclude accept these case-sensitive values:
  • "Series unknown"
  • "Pre seed"
  • "Seed"
  • "Series A"
  • "Series B"
  • "Series C"
  • "Series D"
  • "Series E-J"
  • "Grant"
  • "Angel"
  • "Private equity"
  • "Debt financing"
  • "Non equity assistance"
  • "Post IPO equity"
  • "Undisclosed"
  • "Post IPO debt"
  • "Product crowdfunding"
  • "Equity crowdfunding"
  • "Corporate round"
  • "Convertible note"
  • "Secondary market"
  • "Initial coin offering"
  • "Post IPO secondary"
last_funding_amount and last_funding_type describe the most recent round; total_funding is the cumulative amount across all rounds. lead_investors is a keyword search — "Sequoia" matches “Sequoia Capital” and “Sequoia Capital China”.
Funding signals are sparse for many private companies. Applying these filters narrows results aggressively — combine them with a broad industry or employee_range rather than relying on funding alone.
