✨ What this Actor does / Key features

• 🏢 Whole directory or a slice — pull all 5,900+ YC companies, or narrow to exactly the batch, industry and stage you need.
• 🎛️ Powerful combined filters — batch, status (Active / Acquired / Inactive), industry, subindustry, location, country, minTeamSize / maxTeamSize, tags and isHiring — all AND-ed together.
• 🔎 Free-text search — substring match across company name, one-liner and long description to find, say, every YC company mentioning "agent".
• 👥 Founder enrichment (opt-in) — flip fetchCompanyPageDetails on to add each company's founders[] with name, role, bio, LinkedIn and Twitter — ideal for sales and recruiting.
• 🚀 Launch posts (opt-in) — the same toggle pulls each company's Launch YC posts (title, tagline, date, URL) for product-trend research.
• 🗓️ Every batch since 2005 — Winter (W), Summer (S), Fall (F) and legacy cohorts like IK12.
• 📦 Volume control — cap the run with maxResults (up to 10,000) so you pay only for the companies you need.
• ⚡ Direct HTTP extraction — reads a daily-updated open mirror of YC's official directory; no browser, no bot wall, no API token.
• 📤 Export anywhere — JSON, CSV, Excel, HTML or the Apify API, straight into your CRM, spreadsheet, BI tool or data pipeline.

🚀 Quick start (3 steps)

1. Configure — leave filters empty to pull the whole directory, or set filters (e.g. batch: "W26", industry: "B2B", status: "Active") to narrow it. Toggle fetchCompanyPageDetails on to add founders and launches.
2. Run — click Start. The Actor loads the directory, applies your filters, and (if enabled) enriches each company from its YC page.
3. Get your data — open the Output tab and export to JSON, CSV, Excel or XML, or pull it via the Apify API.

📥 Input

Everything is optional — an empty input returns the full directory (capped by maxResults).

Example — active W26 B2B startups in the US, with founders

{
  "filters": {
    "batch": "W26",
    "industry": "B2B",
    "status": "Active",
    "minTeamSize": 5,
    "location": "United States",
    "tags": ["AI"]
  },
  "maxResults": 200,
  "fetchCompanyPageDetails": true
}

Example — free-text hunt across the whole directory (VC sourcing)

{
  "searchQuery": "agent",
  "maxResults": 500,
  "fetchCompanyPageDetails": false
}

Example — YC startups currently hiring (recruiting)

{
  "filters": {
    "status": "Active",
    "isHiring": true,
    "tags": ["Developer Tools"]
  },
  "maxResults": 300,
  "fetchCompanyPageDetails": true
}

Field	Type	Description
filters	object	Combined filters, AND-ed together. Empty = all companies. See filter keys below.
searchQuery	string	Substring search across company name, one-liner and long description.
maxResults	integer	Cap on returned companies, 1–10000. Full directory is ~6000. Default 100.
fetchCompanyPageDetails	boolean	Scrape each YC company page for founders (name, role, LinkedIn, Twitter) and launch posts. Adds one HTTP request per company. Default false.

Filter keys (inside filters): batch (exact, e.g. "W26"), status (Active / Acquired / Inactive), industry (substring), subindustry, location, country, minTeamSize / maxTeamSize (range), tags (all required), isHiring (boolean).

Tip: filter first, enrich after. Enabling fetchCompanyPageDetails on the full 6,000-company directory means 6,000 extra requests — narrow with filters or maxResults, then turn enrichment on.

📤 Output
