Y Combinator Companies — Full Startup Directory 🚀

Every Y Combinator company (~6,000) as clean, structured rows — batch, industry, status, stage, team size, location, tags, description and website. Search, filter, or export the whole directory. No API key.

Y Combinator has funded the startups behind Airbnb, Stripe, DoorDash, Coinbase, Instacart and thousands more. This Actor turns YC's public company directory into a structured dataset you can query, filter, or pull in full — ideal for sourcing, competitive research, recruiting, market maps and lead lists.

Three modes

Mode	What you get
search	Companies matching a free-text query and/or filters — full profile per company. Leave the query empty to export the entire directory (optionally narrowed by filters).
batch	Every company from a single batch, e.g. W24 or Summer 2021.
digest	One aggregate row: company counts by batch, industry, sub-industry, status, stage, region and tag — a snapshot of the whole YC portfolio.

Each company row

name · batch · status (Active / Inactive / Acquired / Public) · stage · industry · subindustry · tags · team_size · location · regions · one_liner · long_description · website · yc_url · is_hiring · top_company · nonprofit · former_names · launched_at · logo.

Run it on a schedule

Schedule a run to catch each new YC batch the day it's announced, keep a live lead list of companies that are hiring, or track status changes (which startups got acquired or went public) over time.

Notes

• No API key. Reads the same public directory endpoint the YC website itself uses.
• Batch shorthand is accepted: W24 → Winter 2024, S21 → Summer 2021.
• Large pulls (e.g. a whole industry, or the full directory) are fetched batch-by-batch automatically so you always get the complete set, not just the first page.
• Data source: Y Combinator company directory — public, non-personal company information.
