Y Combinator Companies Scraper: YC Startups, Founders & Jobs

Export the Y Combinator startup directory: every YC company (about 6,300, all batches since 2005) with batch, status, industry, tags, location, team size and hiring flag, plus, from each company's YC profile, the founders (name, title, bio, LinkedIn, X), year founded, company LinkedIn / X / Facebook / Crunchbase / GitHub links, news headlines, open jobs, launches and YC partner. Optional founder emails from the company's own website. Three outputs from one actor: companies, founders or jobs (Work at a Startup). No login needed.

What you can do with it

• Lead generation: every startup in a batch, industry or region with founders' LinkedIn and an email for each founder.
• Investor and market research: the whole directory in one run (about a minute without profiles), sliced by batch, industry, tag (AI, Fintech, Developer Tools...), stage, status (Active / Acquired / Public / Inactive) and team size.
• Recruiting and job search: every open job at YC companies with salary, equity, experience, visa and the full description; filter by role, type, location or remote.
• Monitoring: schedule it with "only new" to get each new batch, new company, new founder or new job once.

Input

Empty input = the whole directory. Examples:

{ "batches": ["W25", "S25"], "tags": ["Artificial Intelligence"], "maxItems": 500 }

{ "mode": "founders", "batches": [2025], "findEmails": true }

{ "mode": "jobs", "jobRoles": ["eng"], "jobLocations": ["San Francisco", "remote"] }

Output

One item per company (abridged):

{
  "name": "Sennu AI", "slug": "sennu-ai", "url": "https://www.ycombinator.com/companies/sennu-ai",
  "website": "https://www.sennu.ai", "domain": "sennu.ai", "oneLiner": "We turn traditional companies into AI companies",

  "detailsStatus": "ok"
}

Each founder also has hnUsername, region, photoUrl, ycBatches, isActive and onCompanyPage. Founders mode returns one row per founder with the company as a nested company object. Jobs mode returns

title, location, type, role, roleDetail, salary, salaryMin, salaryMax, salaryCurrency, salaryPeriod, equity, minExperience, visa, skills, remote, postedAt, description, interviewProcess, hiringManager, url

Founder emails (findEmails): each founder gets email and emailSource: website (the company's site publishes it), site-pattern (built from the naming pattern of a founder address the site publishes) or common-pattern (first-name@domain, only for domains that accept mail; labelled as a guess, turn off with emailGuesses: false). Mailboxes are not test-sent. Company-wide addresses and phones from the site come in companyEmails and companyPhones.

Pricing

Pay per result; filters and caps apply before you are charged. Prices on the Bronze plan (lower on Silver and Gold):

The whole directory with founders, news and jobs costs about $12.60 (6,306 companies x $2.00 per 1,000). A run that finds nothing fails instead of silently returning an empty dataset.

How well it works (Oct 2026)

• The whole directory: 6,306 of 6,306 companies YC lists, no duplicates, in about 1.5 minutes without profiles or 17 minutes with them. 6,305 of 6,306 profiles read.
• Founders: 13,308 founders in one founders-mode run (20 minutes), including 1,733 co-founders that company profile pages don't show. 98.7% of companies have at least one founder; 98% of founders shown on profiles have a LinkedIn link, 79% a bio.
• Jobs: all 6,348 open jobs at 1,406 hiring companies, each with its full description (26 minutes); 80% show a salary.
• Founder emails (with findEmails, 200 Summer 2024 companies): an email for 97% of 377 founders.

Compared with Y Combinator Scraper (michael.g)

Same 25 Winter 2024 companies, both with founders and open jobs, October 2026:

Where it still does more: it marks each email "verified" or "risky" after testing the mailbox; we label how each address was found and don't test-send.

Limits and notes

• Covers what YC lists publicly at ycombinator.com/companies. Companies YC hides from the public directory are not included.
• Founder email addresses are not verified by sending mail; emailSource tells you how each one was found.
• Email runs read each company's website, so they are slower: about 2 s per company at the default 256 MB, 0.7 s at 1,024 MB (for runs over ~1,000 companies, pick 1,024 MB in the run options; it costs slightly more).
• Founders: everyone YC lists as a founder of the company, including co-founders the company's profile page doesn't show. Those come with onCompanyPage: false (name, title, HN username, region, photo; no bio or LinkedIn, and no email guess).
• Image links YC signs for one hour (founder photos) are left out; company logos are permanent links.

Is it legal?

It reads public pages anyone can open without an account. Founder names, titles and links are what founders publish on their YC profiles; emails come from the company's own website or a labelled pattern. If you contact people, follow the rules that apply to you (GDPR, CAN-SPAM, and similar).
