## What's an Apify Actor?

Actors are a software tools running on the Apify platform, for all kinds of web data extraction and automation use cases.
In Batch mode, an Actor accepts a well-defined JSON input, performs an action which can take anything from a few seconds to a few hours,
and optionally produces a well-defined JSON output, datasets with results, or files in key-value store.
In Standby mode, an Actor provides a web server which can be used as a website, API, or an MCP server.
Actors are written with capital "A".

## How to integrate an Actor?

If asked about integration, you help developers integrate Actors into their projects.
You adapt to their stack and deliver integrations that are safe, well-documented, and production-ready.
The best way to integrate Actors is as follows.

In JavaScript/TypeScript projects, use official [JavaScript/TypeScript client](https://docs.apify.com/api/client/js.md):

```bash
npm install apify-client
```

In Python projects, use official [Python client library](https://docs.apify.com/api/client/python.md):

```bash
pip install apify-client
```

In shell scripts, use [Apify CLI](https://docs.apify.com/cli/docs.md):

````bash
# MacOS / Linux
curl -fsSL https://apify.com/install-cli.sh | bash
# Windows
irm https://apify.com/install-cli.ps1 | iex
```bash

In AI frameworks, you might use the [Apify MCP server](https://docs.apify.com/platform/integrations/mcp.md).

If your project is in a different language, use the [REST API](https://docs.apify.com/api/v2.md).

For usage examples, see the [API](#api) section below.

# README

## Y Combinator Companies Directory Scraper

Scrape **all 5900+ Y Combinator portfolio companies** across every batch from 2005 onward. Returns name, batch, status, founders (with LinkedIn/Twitter), website, descriptions, industry, subindustry, tags, team size, location, launch year, hiring status.

Uses a daily-refreshed open data mirror of YC's official directory (no auth, no key) plus optional per-company page scrape for founders + launches.

### Features

- Get every YC company in one call (~6000 records, ~3 MB)
- Rich filtering: batch, industry, subindustry, status, team size range, country/location, tags, free-text
- Optional: enrich each company with founders (name, role, LinkedIn, Twitter, bio) and launch posts
- All YC batches: from S05 to W26
- Stable schema across the run — handles YC's occasional field renames

### Input

```json
{
  "filters": {
    "batch": "W26",
    "industry": "B2B",
    "status": "Active",
    "minTeamSize": 5,
    "location": "United States",
    "tags": ["AI"],
    "isHiring": true
  },
  "searchQuery": "agent",
  "maxResults": 100,
  "fetchCompanyPageDetails": false
}
````

| Field | Type | Default | Notes |
|---|---|---|---|
| `filters` | object | `{}` | Combined AND. Empty = all companies |
| `searchQuery` | string | "" | Substring match on name + one\_liner + long\_description |
| `maxResults` | int | 100 | Cap returned (full directory ~6000) |
| `fetchCompanyPageDetails` | bool | false | +1 HTTP req per company for founders & launches |

#### Filter fields

| Key | Match | Example |
|---|---|---|
| `batch` | exact | `"W26"`, `"S25"`, `"W24"`, etc. |
| `status` | exact | `"Active"`, `"Acquired"`, `"Inactive"` |
| `industry` | substring | `"B2B"`, `"Consumer"`, `"Fintech"`, `"Healthcare"` |
| `subindustry` | substring | `"Marketing"`, `"Devtools"` |
| `location` | substring | `"San Francisco"`, `"London"` |
| `country` | substring | `"United States"`, `"India"` |
| `minTeamSize` / `maxTeamSize` | range | `5`, `100` |
| `tags` | all-required | `["AI", "Productivity"]` |
| `isHiring` | exact | `true` |

### Output

```json
{
  "id": 12345,
  "name": "Acme AI",
  "slug": "acme-ai",
  "formerNames": [],
  "batch": "W26",
  "status": "Active",
  "oneLiner": "AI agents for customer support",
  "longDescription": "Acme AI builds autonomous agents that...",
  "website": "https://acme.ai",
  "ycUrl": "https://www.ycombinator.com/companies/acme-ai",
  "logoUrl": "https://bookface-images.s3.amazonaws.com/...",
  "allLocations": "San Francisco, United States",
  "country": "United States",
  "industry": "B2B",
  "subindustry": "B2B -> Sales",
  "tags": ["AI", "Generative AI", "Customer Support"],
  "tagsHighlighted": ["AI"],
  "teamSize": 8,
  "launchedAt": "2026-02-15T00:00:00.000Z",
  "stage": "Seed",
  "isHiring": true,
  "regions": ["America / Canada", "Remote"],
  "founders": [
    { "name": "Jane Doe", "title": "CEO", "bio": "...", "avatarUrl": "...", "linkedinUrl": "https://linkedin.com/in/janedoe", "twitterUrl": null }
  ],
  "launches": [
    { "id": 99, "slug": "acme-ai", "title": "Acme AI: AI agents for support teams", "tagline": "...", "postedAt": "2026-02-20T...", "url": "https://www.ycombinator.com/launches/acme-ai" }
  ],
  "scrapedAt": "2026-05-18T12:00:00.000Z"
}
```

### Use cases

- **VC sourcing:** find recent batches in specific industries (e.g. all W26 fintech with team>5)
- **Sales prospecting:** export YC startups in your target market with founder LinkedIn URLs
- **Recruiting:** filter `isHiring=true` to find startups currently building teams
- **Competitive intel:** track competitors in your YC batch + sub-industry
- **Trend research:** count companies per industry/batch over time
- **Investor pipeline:** identify Series A candidates by team size + batch age
- **Founder outreach:** filter by tag (e.g. "ML Infra") and bulk-email founders

### Notes

- **Open data source:** primary source is `yc-oss.github.io/api/companies/all.json` — community-maintained mirror updated daily from YC's official internal API. Reliable for last 24h freshness.
- **For fresher data** (intra-day, breaking batch announcements), the actor scrapes individual YC company pages when `fetchCompanyPageDetails=true`.
- **No bot detection:** YC's data is intentionally public for founder/funder visibility.
- **Founder enrichment** is opt-in because it adds one HTTP request per company — for the full ~6000 directory that's significant. Filter first, enrich after.
- **Batch codes:** `W{YY}` = Winter, `S{YY}` = Summer, `F{YY}` = Fall (newer), `IK12` = old Imagine K12 cohort.
- **Status values:** `Active` (still operating), `Acquired`, `Inactive` (defunct).
