YC Directory
Y Combinator company list with filters
What YC Directory is for
Y Combinator companies are unusually good prospects for anyone selling to startups. They are funded, they are growing fast, they buy tools quickly, and they are documented publicly in a way most early-stage companies are not.
YC Directory gives you the full directory as structured data, filterable by batch, industry, and stage — the companies from a given cohort, in your vertical, as a list rather than a browsing session.
The timing advantage is real. A company from the most recent batch is actively assembling its stack and has not yet appeared in the contact databases everyone else is buying from.
How it works
Filter by batch, industry, or stage. Batch filtering is the most useful axis because it maps directly to company age and therefore to what they are likely buying.
Each matching company returns with its directory record: name, description, batch, industry tags, team size, location, and website.
Recent batches are prospects for foundational tooling — infrastructure, analytics, hiring. Older batches have scaled and buy differently. The batch field encodes that distinction cleanly.
The natural follow-on is Leads Finder or LinkedIn Company against the resulting domains to identify who to contact at each company.
What each result contains
| Field | Type | Description |
|---|---|---|
| name | string | Company name. |
| description | string | One-line description of what the company does. |
| batch | string | YC batch identifier such as W25 — the best available proxy for company age. |
| industry | string | null | Industry classification, for vertical filtering. |
| website | url | null | Company website. |
| teamSize | number | null | Headcount at time of listing. |
| location | string | null | Primary location. |
| status | string | null | Operating status, where published. |

Example use case
When to choose this source
Use this for a fast, broad view of the YC universe filtered by batch and category. For deeper per-company detail including founder information, YC Scraper goes further at a higher price. For startups outside YC, this source will not help at all.
Limitations worth knowing
Coverage is YC companies only. It is a deliberately narrow, high-quality slice of the startup world, not a general startup database.
Directory records are company-level. Founder names and contact details require YC Scraper or a follow-up enrichment pass.
Team-size figures reflect the directory listing and lag reality at fast-growing companies, sometimes badly.
YC companies are among the most heavily prospected businesses in existence. The batch-timing advantage helps, but assume your message is one of many.

Frequently asked questions
- How is this different from YC Scraper?
- Directory is the broad list at ten credits per result — good for building a filtered target list. Scraper goes much deeper per company, including founder detail, at fifty-five. Start here, then use Scraper on the shortlist.
- Can I filter by batch?
- Yes, and it is the most useful filter available. Batch maps to company age, which maps to what they are currently buying.
- Do I get founder contact details?
- Not from this source. Use YC Scraper for founder-level detail, or run Leads Finder against the company domains.
- How current is the directory?
- It reflects the published directory, which is updated as new batches are announced. Team sizes and status lag reality at the fastest-growing companies.
