# YC public / SEC-relevant companies — EDGAR CIKs and filings

Retrieved **Monday Aug 24, 2026** (America/Denver). All CIKs, tickers, dates, and counts are from official SEC EDGAR sources. **Nothing was invented.**

## Sources

- [SEC company_tickers.json](https://www.sec.gov/files/company_tickers.json)
- [SEC company_tickers_exchange.json](https://www.sec.gov/files/company_tickers_exchange.json)
- [data.sec.gov submissions](https://data.sec.gov/submissions/) (`CIK##########.json`, plus extra files when present)
- [EFTS search-index](https://efts.sec.gov/LATEST/search-index)
- [EDGAR browse-edgar](https://www.sec.gov/cgi-bin/browse-edgar)

User-Agent used: `YC-SEC-Research/1.0 (research@example.com; EDGAR company matching for YC public companies)`.

## How to read the table

- **CIK** is the primary *reporting* CIK (public successor for SPACs / reverse mergers).
- **First filing (YC)** is the earliest EDGAR filing attributable to the YC operating company (private Form D when that CIK was found). If only a SPAC/predecessor CIK exists, that is flagged.
- **Latest filing** is the latest filing on the primary reporting CIK.
- **Ticker** is the *current* `company_tickers.json` / submissions ticker, or a *historical* ticker confirmed in an EDGAR filing / EFTS display name if the issuer is delisted.
- **Form counts** are for the primary CIK only (S-1, 10-K, 10-Q, 8-K, Form 4, Form D, 13F). Amendments (`S-1/A`, `10-K/A`, …) are in the JSON, not this compact cell.
- **13F** is 0 for every issuer here (13F-HR is filed by institutional investment managers, not these companies).

## Companies with no US registration / listing

These have EDGAR hits but **no** S-1 / 8-A12B / 10-K and are **not** in `company_tickers.json`:

| Company | Batch | CIK | What EDGAR shows |
|:--------|:------|:----|:-----------------|
| Stripe | S09 | 0001691342 | Stripe, Inc.: 14 filings, forms ['D', 'D/A'] | [browse](https://www.sec.gov/cgi-bin/browse-edgar?action=getcompany&CIK=0001691342&owner=exclude&count=40) |
| Meesho | S16 | 0001686166 | Meesho, Inc.: 6 filings, forms ['D'] | [browse](https://www.sec.gov/cgi-bin/browse-edgar?action=getcompany&CIK=0001686166&owner=exclude&count=40) |

No company in the 25-name list had *zero* US EDGAR hits. Meesho and Groww are India listings (YC status Public) with US Form D only. Stripe remains private on EDGAR (Form D only).
