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. For more details, see Apify documentation as [Markdown index](https://docs.apify.com/llms.txt) and [Markdown full-text](https://docs.apify.com/llms-full.txt). # README ## Y Combinator Companies Directory Scraper Pulls Y Combinator portfolio companies filtered by batch, industry, region, or status. Returns structured data per company: - Name, slug, one-line description, long description - Batch (e.g. `W26`, `S25`), founded year - Status (`Active`, `Acquired`, `Inactive`, `Public`) - Team size, location, regions, industries, tags - Website, YC profile URL - Founders with names and roles where available ### Why use this Every B2B sales team targeting funded startups builds a YC list eventually. This actor builds it on demand, filtered to the slice you care about (e.g. `W26 + B2B + United States`). Pairs with the AI Sales Personalizer for personalised outreach. ### Input ```json { "batches": ["W26", "S25"], "industries": ["B2B", "Fintech"], "regions": ["United States of America"], "statuses": ["Active"], "max_companies": 200, "preview": false } ```` All filters are optional and combine with AND logic (a company must match every filter you set). Leave a filter empty to disable it. ### Pricing - **Pay per company.** US$0.02 per company returned. - Preview mode returns the first 10 companies free. - Filtering happens server-side, so you only pay for companies that match. ### Output One dataset record per company: ```json { "name": "Acme", "slug": "acme", "yc_url": "https://www.ycombinator.com/companies/acme", "batch": "W26", "status": "Active", "team_size": 12, "founded": 2026, "location": "San Francisco, CA", "regions": ["United States of America"], "industries": ["B2B", "Productivity"], "tags": ["AI", "API"], "description_short": "AI-native procurement for SMBs.", "description_long": "Acme automates...", "website": "https://acme.com", "founders": [ {"name": "Jane Smith", "role": "CEO"}, {"name": "John Doe", "role": "CTO"} ], "scraped_at": "2026-05-30T22:25:00Z" } ``` ### Pairs well with - AI Sales Personalizer: feed YC company URLs in to generate personalised outreach. - Funding Round Tracker: cross-reference YC batches with recent fundings. - Hiring Signal Detector: filter YC companies that are also actively hiring. - Greenhouse Jobs Scraper: pull all roles at the YC companies you care about. ### Integrations This actor works out of the box with every Apify-supported integration: - **API**: call via Apify API or any official SDK (Python, JavaScript, PHP, .NET). Returns a clean dataset URL. - **Schedule**: set a daily, weekly, or custom cron cadence in Apify Console. Combine with `notification` for fresh feeds. - **Webhooks**: wire `ACTOR.RUN.SUCCEEDED` to Slack, Discord, Zapier, Make, n8n, Pipedream, or any HTTPS endpoint. - **MCP**: this actor is discoverable through Apify's hosted MCP server at `mcp.apify.com` for Claude, Cursor, Cline, Windsurf, and other MCP clients. - **n8n / Make / Zapier**: native HTTP-Request integration. Trigger the actor on schedule, pipe results to Google Sheets, Airtable, your CRM, or any database. ### Try it free Every Apify user gets **$5/month in free platform credits** (around 250 events at this actor's per-event price).

Latest version live on Apify Store. ### Last Updated 2026-06-03 # Actor input Schema ## `batches` (type: `array`): List of YC batch codes (e.g. 'S25', 'X25', 'F24'). Leave empty to scrape across all batches and use the 'industries' or 'regions' filter instead. Pick a batch from https://www.ycombinator.com/companies if you want to scope to one specific cohort. ## `industries` (type: `array`): Filter companies by YC industry tag. Common values: 'B2B', 'Consumer', 'Healthcare', 'Fintech', 'AI', 'Climate', 'Government'. ## `regions` (type: `array`): Filter by region. Common values: 'United States of America', 'United Kingdom', 'Australia', 'Canada', 'India'. ## `statuses` (type: `array`): Limit by company status. Default includes active and public; can also add 'Acquired', 'Inactive', 'Public'. ## `max_companies` (type: `integer`): Hard cap on how many companies the actor returns. Pages of 50 are fetched until cap. Default 200, max 5000. ## `preview` (type: `boolean`): Run the first page (max 10 companies) without charging. Use to verify filters before bulk runs. ## Actor input object example ```json { "batches": [ "S25", "X25" ], "industries": [], "regions": [], "statuses": [ "Active" ], "max_companies": 200, "preview": false } ``` # API You can run this Actor programmatically using our API.
