# Y Combinator / YC Continuity / YC funds — SEC/EDGAR entity map

**Prepared for:** Jonathan Drake  
**As of:** Monday, 24 August 2026 (America/Denver)  
**Method:** Live retrieval from SEC EDGAR (browse-edgar, EFTS search-index, `data.sec.gov/submissions`, `company_tickers.json`) and IAPD/IARD (Form ADV CRD 171730). **No CIKs or filing counts were invented.** Every number below was read from those official responses.

## Why a naive EDGAR search for "Y Combinator" looks empty

There is **no public company** named Y Combinator, and the operating adviser **does not file on EDGAR**.

1. **No ticker / not in `company_tickers.json`.**  
   Retrieved `https://www.sec.gov/files/company_tickers.json` on 24 Aug 2026: **10,403** issuers, **zero** titled Y Combinator / YC. The EDGAR ticker box and any "public company" filter therefore return nothing.

2. **The adviser has no CIK.**  
   Legal name **Y Combinator Management, LLC**, primary business name **Y COMBINATOR**, CRD **171730**, SEC file **802-80528**.  
   - IAPD: [https://adviserinfo.sec.gov/firm/summary/171730](https://adviserinfo.sec.gov/firm/summary/171730)  
   - ADV PDF (filed 27 Mar 2026): [https://reports.adviserinfo.sec.gov/reports/ADV/171730/PDF/171730.pdf](https://reports.adviserinfo.sec.gov/reports/ADV/171730/PDF/171730.pdf)  
   Form ADV Item 1.D.(3) is explicit: **CIK Numbers — No Information Filed**. Form ADV is an **IARD/IAPD** filing, not an EDGAR submission. `802-` means **Exempt Reporting Adviser** (not a fully registered `801-` RIA). ERA since **23 Oct 2014** (California ERA 19 Apr 2018). Item 2.B.(1): venture-capital adviser exemption, Advisers Act **§ 203(l)** / rule 203(l)-1.

3. **Name mismatch.**  
   Most vehicles file under abbreviated names (`YC II, L.P.`, `YC ESP24, L.P.`, `YCC20, L.P.`, `YCCG21, L.P.`, `YCP24, L.P.`, `YC ECO24, L.P.`). Searching **Y Combinator LLC** or **Y Combinator Management** as a company name returns **no EDGAR registrant**.  
   The old company-name search *does* find the five issuers whose legal names contain the words "Y Combinator":  
   [https://www.sec.gov/cgi-bin/browse-edgar?company=Y+Combinator&owner=exclude&action=getcompany](https://www.sec.gov/cgi-bin/browse-edgar?company=Y+Combinator&owner=exclude&action=getcompany)

4. **Core seed funds never filed Form D.**  
   The 27 Mar 2026 ADV lists **Y COMBINATOR FUND I, LP**, **Y COMBINATOR FUND II, LP**, and **YCVC FUND I, L.P.** with placeholder Form D number `021-9999999999`. Those names have **no EDGAR CIK** in entity autocomplete or company search.

5. **Only Form D / D/A on EDGAR.**  
   All 29 first-party EDGAR filings retrieved are Regulation D notices (Rule 506(b), ICA § 3(c)(1) and/or § 3(c)(7)). **No 10-K, 10-Q, 8-K, S-1, 13F, or 13G** under these CIKs. Filters for periodic or ownership reports are empty.

6. **Full-text search is the wrong tool.**  
   EFTS `q="Y Combinator"` returns **1,002** document hits — almost all *other* issuers mentioning YC. That is not a registrant list.

**What works:** company search / `keysTyped` for `Y Combinator`, `YC II`, `YC ESP`, `YC AFFILIATES`, `YC PRINCIPALS`, `YCC20`, `YCCG21`, `YCP24`, `YC ECO24`; then `https://data.sec.gov/submissions/CIK##########.json`. For the adviser, use IAPD, not EDGAR.

EDGAR issuers **not** on that ADV 7.B list: **YC III, L.P.** (0001723395), **YC Principals Fund III, L.P.** (0001724749) — 2017 Form Ds, likely legacy; **Y Combinator ES26, LLC** (0002131827) — Form D 27 Apr 2026, after the ADV.

## Form D filings that *mention* Y Combinator (not YC issuers)

EFTS Form D phrase search `q="Y Combinator"` (2005-01-01 to 2026-08-24): **28** hits.  
https://efts.sec.gov/LATEST/search-index?q=%22Y+Combinator%22&forms=D&dateRange=custom&startdt=2005-01-01&enddt=2026-08-24

That set mixes (a) the five first-party issuers whose names contain "Y Combinator", (b) third-party access funds below, and (c) portfolio companies that list Y Combinator as a related person / investor (examples from the EFTS entity aggregation: Poolit, Inc. 0001921904; Spaciously, Inc. 0001959396; Bloom Credit, Inc. 0001720741; TurboDocx, Inc. 0002015141; HomeHero AI, Inc. 0002128781). Those portfolio-company CIKs are **not** YC legal entities.

Abbreviated first-party vehicles (`YC II`, `YC ESP24`, `YCC20`, …) usually **do not** contain the phrase and are missed by this full-text query.

---

## Third-party access funds that use "Y Combinator" in the *issuer* name

Not 335 Pioneer Way. Not on YC's ADV. Retrieved so they are not mistaken for YC vehicles.
