# Orange County Startups & VC Firms 2026: Anduril (Costa Mesa), Not LA County

> As of July 2026 we cover Anduril as Orange County (Costa Mesa HQ commonly cited) — not Los Angeles County. No OC-HQ funds in directory; national defense investors and honest gaps.

**Short answer (as of July 2026):** The Orange County company we cover is **[Anduril](/startup/anduril)** — HQ commonly cited as **Costa Mesa, CA (Orange County)**, not Los Angeles County. We have **no OC-HQ fund profiles**. Anduril’s directory investors are national: [a16z](/fund/andreessen-horowitz), [Thrive Capital](/fund/thrive-capital), [Founders Fund](/fund/founders-fund), [Lux Capital](/fund/lux-capital), [General Catalyst](/fund/general-catalyst). This page is the HQ-honest OC map — not an LA County dump.

City hub (live matches): [/vc/orange-county](/vc/orange-county). All cities: [/cities](/cities). Fund index: [/directory](/directory).

### Scope (OC ≠ LA County)

| Include | Exclude |
|---|---|
| Irvine, Newport Beach, Costa Mesa, Anaheim, Huntington Beach, Orange County | El Segundo, Hawthorne, Torrance, Santa Monica, City of Los Angeles |
| Anduril curated as Costa Mesa / OC | Relabeling South Bay defense as “OC startups” |
| National defense/deep-tech funds on Anduril’s cap table path | Invented OC AUM rankings |

**Primary JTBD:** OC founder or defense scout — “Is Anduril OC or LA, who backed it in your directory, and what else do you actually cover in Orange County?”

### Funds with Orange County HQ (directory)

| Firm | HQ (directory) | Stage | Profile |
|---|---|---|---|
| *None* | — | — | No Irvine/Newport/Costa Mesa/Anaheim/OC location matches in `src/data/funds/individual/` |

### Startups we cover (Orange County)

| Startup | One-liner | Stage / status | HQ note | Profile | Notable investors (directory) |
|---|---|---|---|---|---|
| [Anduril](/startup/anduril) | Autonomous defense systems — drones, sensors, C2; software-defined production | Growth / private (Series H May 2026) | HQ commonly cited as Costa Mesa, CA (Orange County); JSON lacks `hq` | [/startup/anduril](/startup/anduril) | [a16z](/fund/andreessen-horowitz), [Thrive](/fund/thrive-capital), [Founders Fund](/fund/founders-fund), [Lux](/fund/lux-capital), [General Catalyst](/fund/general-catalyst) |

**Why Anduril is on this hub:** Public and our editorial coverage place HQ in **Costa Mesa**, which is Orange County — not LA County. We curate the ID so `/vc/orange-county` surfaces it even without an `hq` string.

| Irvine / Newport Beach medtech and device companies | Long-running OC thesis beyond defense | High |
| OC enterprise / consumer SaaS with local HQ | Irvine–Newport founder demand | High |
| Orange County seed funds and family offices | First checks before national Series A | Medium |
| Additional OC defense suppliers beyond Anduril | Cluster completeness for scouts | Medium |
