# Austin & Texas Startups We Cover 2026: Hard Tech, Defense, Energy

> Directory companies mapped to Austin and Texas — Base Power, CesiumAstro, Galadyne, Saronic, Apptronik — plus honest Texas/defense adjacency for Castelion and Anduril, with stage and investor links.

**Short answer (as of July 2026):** In our directory, the clearest **Austin / Texas HQ** hard-tech coverage set is [Base Power](/startup/base-power), [Galadyne](/startup/galadyne), [CesiumAstro](/startup/cesiumastro), [Saronic](/startup/saronic), and [Apptronik](/startup/apptronik). [Castelion](/startup/castelion) is **Torrance, CA HQ** with Texas manufacturing/test adjacency; [Anduril](/startup/anduril) is **Orange County / LA** — useful defense comps only. [Hadrian](/startup/hadrian) is Torrance/LA manufacturing, not Texas HQ. Sister hub: [Austin VC firms for hard tech 2026](/austin-vc-firms-hard-tech-2026). Deal context: [Austin Q1 $4.2B](/2026-austin-q1-record-4-2b-hard-tech-defense) · [CesiumAstro $470M](/2026-cesiumastro-470m-aerospace-austin).

### Primary coverage: Austin / Texas–anchored

Prefer `hq` from startup JSON when present. Where `hq` is missing, we label **“HQ commonly cited as…”** from unambiguous public materials — not invented city stickers.

| Startup | One-liner | Stage / status | HQ label | Profile | Notable investors (directory) |
|---|---|---|---|---|---|
| [Base Power](/startup/base-power) | Residential batteries + retail power plans as a Texas-centric virtual power plant | Growth / private | **Austin, Texas** (`hq`) | [/startup/base-power](/startup/base-power) | [a16z](/fund/andreessen-horowitz), [Thrive](/fund/thrive-capital), [Lightspeed](/fund/lightspeed-venture-partners-nyc), [Spark](/fund/spark-capital), [Altimeter](/fund/altimeter-capital), [Ribbit](/fund/ribbit-capital); Addition (no `/fund/` here) |
| [Galadyne](/startup/galadyne) | Liquid-propulsion missile systems aimed at scalable strike/intercept manufacturing | Pre-seed / private | **Austin, Texas** (`hq`) | [/startup/galadyne](/startup/galadyne) | [a16z](/fund/andreessen-horowitz) |
| [CesiumAstro](/startup/cesiumastro) | Phased-array / software-defined space & defense communications manufacturing | Growth / private | **HQ commonly cited as Austin / Bee Cave, Texas** (no `hq` field yet; Austin tags + company materials) | [/startup/cesiumastro](/startup/cesiumastro) | Investor IDs not yet populated in JSON — see [$470M coverage](/2026-cesiumastro-470m-aerospace-austin) |
| [Saronic](/startup/saronic) | Autonomous surface vessels; Series D funded production / shipyard scale | Growth / private | **HQ commonly cited as Austin, Texas** (Austin tags + company/press) | [/startup/saronic](/startup/saronic) | [a16z](/fund/andreessen-horowitz), [Kleiner Perkins](/fund/kleiner-perkins), [Bessemer](/fund/bessemer-venture-partners), [8VC](/fund/8vc) |
| [Apptronik](/startup/apptronik) | Humanoid robot platform (Apollo) moving into commercial pilots | Other / private (large extension) | **HQ commonly cited as Austin, Texas** (Austin tags + company materials; UT Austin spinout roots) | [/startup/apptronik](/startup/apptronik) | Investor IDs not yet populated — $520M extension covered in directory highlights / Q1 recap |

These five are the companies a founder or scout should open first when the search intent is “Austin hard tech we actually profile.”

### Why each Austin name is on the shortlist

**[Base Power](/startup/base-power)** — ERCOT-native energy hardware with software dispatch. Series C scale ($1B led by Addition per highlights) shows climate/infra growth capital will fund install factories in Texas, not only California.

**[Galadyne](/startup/galadyne)** — Early American Dynamism bet: liquid propulsion for missiles with an Austin HQ and a16z-led pre-seed. Useful for founders raising before production revenue.

**[CesiumAstro](/startup/cesiumastro)** — Dual-use space communications manufacturing; $470M round was a pillar of Austin’s [Q1 2026 record](/2026-austin-q1-record-4-2b-hard-tech-defense). Read the [dedicated deal note](/2026-cesiumastro-470m-aerospace-austin) for problem framing and market signal.

**[Saronic](/startup/saronic)** — Largest disclosed Austin defense round in our Q1 coverage ($1.75B at $9.25B). Cap table bridges Austin HQ capital ([8VC](/fund/8vc)) and national growth names ([Kleiner Perkins](/fund/kleiner-perkins), [Bessemer](/fund/bessemer-venture-partners), [a16z](/fund/andreessen-horowitz)).

**[Apptronik](/startup/apptronik)** — Humanoid robotics at commercial-pilot scale; $520M extension sits next to Saronic/CesiumAstro in the city’s hard-tech narrative even though the buyer set is industrial, not DoD-first.

### Related / adjacency (not Austin HQ)

| Startup | Why linked here | HQ reality | Profile | Notable investors (directory) |
|---|---|---|---|---|
| [Castelion](/startup/castelion) | Hypersonic / SRM manufacturing; public materials cite manufacturing ops including **Texas** (e.g. Midland test/production) alongside CA/NM | **Torrance, California HQ** — Texas ops adjacency only | [/startup/castelion](/startup/castelion) | [a16z](/fund/andreessen-horowitz), [Lightspeed](/fund/lightspeed-venture-partners-nyc), [Altimeter](/fund/altimeter-capital), [General Catalyst](/fund/general-catalyst) |
| [Anduril](/startup/anduril) | Category benchmark for software-defined defense at production scale; same LP/partner conversations Austin defense founders enter | **Costa Mesa, Orange County, California** — not Texas HQ | [/startup/anduril](/startup/anduril) | [a16z](/fund/andreessen-horowitz), [Thrive](/fund/thrive-capital), [Founders Fund](/fund/founders-fund), [Lux Capital](/fund/lux-capital), [General Catalyst](/fund/general-catalyst) |
| [Hadrian](/startup/hadrian) | Automated aerospace/defense factories — manufacturing comps for Texas dual-use supply chains | **Torrance / LA area, California** — not Texas HQ | [/startup/hadrian](/startup/hadrian) | [a16z](/fund/andreessen-horowitz), [Founders Fund](/fund/founders-fund), [Lux Capital](/fund/lux-capital), [Altimeter](/fund/altimeter-capital) |

If you swap “Austin” into Anduril or Hadrian copy, the page becomes slop. We keep them in a **related** bucket so Texas founders can shortlist investors without false geography.

### Texas scan note (directory search)

A ripgrep pass over `src/data/startups/individual` for Austin/Texas city signals surfaces a **thin** hard-tech set: explicit `hq: "Austin, Texas"` today on Base Power and Galadyne; Austin tags / copy on CesiumAstro, Saronic, and Apptronik. Other “Texas” string hits are mostly unrelated (TxO program names, ticker-like IDs, non-geo fields). This hub does **not** invent a long Texas roster beyond what the files support.

### Coverage gaps

| Gap | Honest status |
|---|---|
| Local Austin SaaS / consumer names | Mostly absent from startup JSON — do not fabricate profiles |
| CesiumAstro / Apptronik investor arrays | Rounds covered editorially; `/fund/` links incomplete until JSON is enriched |
| Local early-stage funds (Silverton, Next Coast, etc.) | Named in [Q1 recap](/2026-austin-q1-record-4-2b-hard-tech-defense); many lack `/fund/` pages |
| Broader Texas cities (Dallas, Houston) hard tech | Not yet a first-class cluster in our startup files |

### How to use this page

1. **Founders:** Pitch [Austin hard-tech funds](/austin-vc-firms-hard-tech-2026) with the closest peer above (Saronic vs Galadyne is a different stage conversation).  
2. **Investors / scouts:** Start with Austin HQ rows; use Anduril/Hadrian/Castelion only for category comps and syndicate patterns.  
3. **Operators / journalists:** Prefer `hq` and dated round highlights over city mythology.  
4. **Next:** [/directory](/directory) for the full fund list; Q1 + CesiumAstro posts for 2026 timing.
