What it does

The actor searches the Y Combinator company directory, applies your keyword, batch and industry filters, and writes one normalized record per company to the run's dataset. When includeFounders is on (the default), each record also carries the founder roster with LinkedIn and X/Twitter profiles, the company's LinkedIn, X/Twitter, GitHub, Facebook and Crunchbase links, the year founded, and the YC group partner.

An optional paid add-on (enrichContacts) attempts to find a public business contact email and person for companies that do not already expose one. Missing source values are returned as null, never invented.

Quickstart

Open the actor, paste this into the input, and press Run. It returns AI companies with founders.

{
  "searchQuery": "AI",
  "maxCompanies": 10,
  "includeFounders": true
}

Every input field is optional. With an empty input the actor lists YC companies with no keyword filter (default maxCompanies is 10).

maxCompanies	integer	no	10	Maximum number of companies to collect. Free Apify plans are capped at 10 per run.

batch	string	no	(any)	Keep only one YC batch. Accepts W21/S22 or Winter 2021/Spring 2024.
industry	string	no	(any)	Keep only one industry, for example B2B, Fintech, Healthcare, Consumer, Education, Industrials.
includeFounders	boolean	no	true	Also collect the founder roster and the company's social/Crunchbase links, year founded and YC group partner. Off gives a faster directory-only run.
enrichContacts	boolean	no	false	Paid add-on. For each result without an email, attempt to find a public business email and contact person. Billed per attempt, plus an extra charge only when an email is found.
enrichContactsMax	integer	no	50	Cap how many results the add-on tries to enrich. Free Apify accounts are capped at 3.

Run via API and CLI

Start a run and wait for it to finish, then read the dataset. Replace <TOKEN> with your Apify API token.

Run synchronously and get dataset items in one call:

curl -X POST "https://api.apify.com/v2/acts/scrapers_lat~ycombinator-companies-scraper/run-sync-get-dataset-items?token=<TOKEN>" \
  -H "Content-Type: application/json" \
  -d '{"searchQuery":"fintech","batch":"W21","maxCompanies":50,"includeFounders":true}'

Start a run asynchronously:

curl -X POST "https://api.apify.com/v2/acts/scrapers_lat~ycombinator-companies-scraper/runs?token=<TOKEN>" \
  -H "Content-Type: application/json" \
  -d '{"industry":"Healthcare","maxCompanies":200}'

Apify CLI:

apify call scrapers_lat/ycombinator-companies-scraper \
  --input '{"searchQuery":"developer tools","enrichContacts":true,"enrichContactsMax":25}'

Fetch results

Every run writes to a dataset. Fetch items as JSON, CSV, or Excel by changing format:

# JSON
curl "https://api.apify.com/v2/datasets/<DATASET_ID>/items?token=<TOKEN>&clean=true&format=json"

# CSV
curl "https://api.apify.com/v2/datasets/<DATASET_ID>/items?token=<TOKEN>&clean=true&format=csv"

# Paginate large datasets
curl "https://api.apify.com/v2/datasets/<DATASET_ID>/items?token=<TOKEN>&offset=1000&limit=1000"

<DATASET_ID> is returned as defaultDatasetId in the run object. Use offset and limit to page through large result sets. clean=true drops empty and internal fields.

Billing and limits

• Pay per result. You are charged per company record returned (result event). See the pricing tab for the current per-result price.
• Contact enrichment add-on. When enrichContacts is on, two extra events apply: contact-search-attempt (once per row attempted, found or not) and contact-email-found (only when a public email is found). Off by default.
• No charge on failure. If a run errors, the actor writes a single item with a populated error field and does not charge for it. Empty runs cost nothing.
• Spend cap respected. Set maxTotalChargeUsd on the run; once reached, the actor stops emitting and charging further billable results.
• Free Apify plans are capped at 10 records per run, and enrichment is capped at 3 attempts. Upgrade for higher maxCompanies.

FAQ and troubleshooting

A run returned 0 records. Why? The keyword, batch or industry filter matched nothing. Loosen filters (remove batch or industry, or widen searchQuery). Zero-result runs are not charged.

How do I get founders and social links? Keep includeFounders on (the default). Each record then carries the founder roster with LinkedIn and X/Twitter, plus the company's social and Crunchbase links.

How does contact enrichment bill? Turn on enrichContacts. You pay contact-search-attempt once per attempted row, and contact-email-found only when a real public email is found. Emails are never invented; unfound rows carry emailStatus: not_found.

What batch formats are accepted? Both short codes (W21, S22) and full labels (Winter 2021, Spring 2024).

Is this an official Y Combinator tool? No. This actor is independent and has no affiliation with Y Combinator. It reads only data that is publicly available in the YC company directory.
