# Companies

## 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.

| Example    | Industry                             |
| :--------- | :----------------------------------- |
| `"5112"`   | Software Publishers                  |
| `"5182"`   | Data Processing, Hosting             |
| `"541511"` | Custom Computer Programming Services |
| `"541512"` | Computer Systems Design Services     |
| `"541613"` | Marketing Consulting Services        |

## 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.

| Example  | Industry                      |
| :------- | :---------------------------- |
| `"7372"` | Prepackaged Software          |
| `"7371"` | Computer Programming Services |
| `"7389"` | Business Services, NEC        |
| `"6199"` | Finance Services              |
| `"5961"` | Catalog, Mail-Order Houses    |

## 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".

| Filter        | Unit                               | Typical range         |
| :------------ | :--------------------------------- | :-------------------- |
| `revenue`     | USD per year                       | `1_000_000` – `2.1e9` |
| `web_traffic` | Monthly visits (estimated)         | `1_000` – `1e10`      |
| `ad_spend`    | USD per month on Google Ads (est.) | `100` – `1e9`         |

<Note>
  `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.
</Note>

<Warning>
  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.
</Warning>

## 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.

| Filter                | Shape                  | Unit / Values                                                 |
| :-------------------- | :--------------------- | :------------------------------------------------------------ |
| `total_funding`       | `{ min, max }`         | Total raised across all rounds, USD. `0` = unset.             |
| `last_funding_amount` | `{ min, max }`         | Amount raised in the most recent round, USD. `0` = unset.     |
| `last_funding_year`   | `{ min, max }`         | Calendar year of the most recent round. `0` = unset.          |
| `last_funding_type`   | `{ include, exclude }` | Most recent round type — case-sensitive enum (see below).     |
| `lead_investors`      | `{ include, exclude }` | Keyword search across lead investor names (e.g. `"Sequoia"`). |

### Last Funding Type

`last_funding_type.include` and `last_funding_type.exclude` accept these **case-sensitive** values:

<Accordion title="View all accepted funding type values (23)">
  * `"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"`
</Accordion>

<Note>
  `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".
</Note>

<Warning>
  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.
</Warning>
