# Houston Startups & VC Firms 2026: Energy, Space, Enterprise — Honest Map

> Houston energy-transition and NASA JSC thesis with zero Houston HQ matches in our directory. Texas energy/space/enterprise companies we cover stay labeled (Austin HQ vs adjacency) — plus Axiom/Fervo-class gaps.

**Short answer (as of July 2026):** Our directory has **no Houston HQ startups** and **no Houston fund HQ matches**. A targeted scan of Texas **energy / space / enterprise** companies we *do* cover shows they are **Austin-anchored** (or California HQ with Texas ops) — we **do not steal** them for Houston. This hub still finishes a job: honest map, adjacency comps, capital shortlist, gaps. [/vc/houston](/vc/houston) · [/cities](/cities) · [/directory](/directory) · sister Texas hard-tech map: [Austin startups we cover](/austin-texas-startups-we-cover-2026).

### Primary job

**Audience:** Founders and scouts searching “Houston startups,” “Houston energy VC,” or “Houston space startups.”

**Job:** Orient on energy transition + NASA JSC + Medical Center — without inventing a Houston roster from Austin’s book.

### Funds table (directory HQ matches)

| Firm | HQ (directory) | Profile | Notes |
|---|---|---|---|
| — | — | — | **No Houston / Woodlands / Sugar Land fund HQ matches** |

### Coverage gaps (Houston names that matter)

| Name | Why it matters | Priority |
|---|---|---|
| Axiom Space | Commercial space station / JSC-adjacent flagship | High |
| Intuitive Machines | Houston lunar lander / commercial space proof point | High |
| Fervo Energy / Solugen–class energy transition | Core energy-transition fundraising narrative | High |
| Medical Center digital health / device spinouts | Texas Medical Center cluster | Medium |
| Houston-HQ energy VC firms | No `/fund/` HQ match yet | High |

### How to use this page

1. Live hub: [/vc/houston](/vc/houston).  
2. For Texas hard-tech **HQ** companies, use [Austin startups we cover](/austin-texas-startups-we-cover-2026) — do not copy those rows into Houston tallies.  
3. Use [SpaceX](/startup/spacex) / [RigUp](/startup/rigup) only as **category or buyer-market** comps with labels above.  
4. Shortlist capital in [/directory](/directory). All cities: [/cities](/cities).
