San Antonio Startups and VC Firms in 2026: Darkhive, Robotics, and Cyber
San Antonio’s venture map in 2026 — Darkhive, Plus One Robotics, Insane Cyber, SafeRide Health, plus Active Capital and Alamo Angels.
San Antonio’s venture job is military-adjacent autonomy and cyber, warehouse robotics, and healthcare access — not Austin re-labeling. We profile four San Antonio HQ companies plus Active Capital and Alamo Angels.

What San Antonio is (and is not)
| San Antonio is… | San Antonio is not… |
|---|---|
| Home to Darkhive defense autonomy and Insane Cyber OT security | Austin defense companies counted as SA HQ |
| Strong on Alamo Angels / Active Capital formation | A complete Rackspace alumni index (gaps) |
| Healthcare access via SafeRide NEMT | Only a slogan without company names |
Startups we cover in San Antonio
| Company | What they do | Stage / status | Notable capital | Profile |
|---|---|---|---|---|
| Darkhive | U.S.-made autonomous UAS + secure edge software | Series B $30M (May 2026) | Alamo Angels | /startup/darkhive |
| Plus One Robotics | AI vision / supervised-autonomy for parcel picking | Growth; Series C $50M (Mar 2023) | — | /startup/plus-one-robotics |
| Insane Cyber | Automated OT/ICS cybersecurity | Seed $4.2M (May 2024) | — | /startup/insane-cyber |
| SafeRide Health | Technology-first NEMT for Medicaid/Medicare | Growth; Series C (Oct 2023) | — | /startup/saferide-health |
Why these names matter
Darkhive is the defense autonomy signal — U.S.-made UAS with a $30M Series B (May 2026) and Alamo Angels in the early story. Dual-use customers are the diligence artifact.
Plus One Robotics shows warehouse automation scale from SA HQ ($50M Series C, March 2023).
Insane Cyber and SafeRide Health cover OT security seed and NEMT growth — cyber and healthcare access without inventing a full NSA Texas roster.
Local investors (San Antonio HQ)
| Firm | Role | Stages / product | Profile |
|---|---|---|---|
| Active Capital | SA pre-seed venture | Pre-seed / seed | /fund/active-capital |
| Alamo Angels | San Antonio angel network (Darkhive) | Angel / seed | /fund/alamo-angels |
National capital that serves San Antonio (by thesis)
| Firm | Fit for SA founders | Profile |
|---|---|---|
| In-Q-Tel | Strategic path for national security customers | /fund/in-q-tel |
| Lux Capital | Deep tech / defense-adjacent | /fund/lux-capital |
| Founders Fund | Ambitious defense / hard tech | /fund/founders-fund |
| 8VC | Defense, advanced manufacturing | /fund/8vc |
| Bessemer Venture Partners | Enterprise / robotics software | /fund/bessemer-venture-partners |
Local seed vs national Series A — what differs
| Active Capital / Alamo Angels | National Series B+ | |
|---|---|---|
| Best for | First checks, dual-use intros | Scaling defense, robotics, or NEMT |
| What they underwrite | Mission or local buyer access | Category and commercial GTM |
| Mistake | Counting Austin HQs as SA density | Pitching In-Q-Tel with zero contract proof |
Worked example (illustrative)
Setup: An SA cyber/autonomy team wins an Alamo Angels check and a DoD pilot.
Move: They raise a $20–30M Series B from defense-aware national capital (Darkhive-class).
Punch: Mission customer proof was the artifact. Local angels bought formation time — not Series B ownership math.
When San Antonio is the wrong capital market
- You re-home Austin defense startups as San Antonio HQ.
- You invent broader JBSA
/startup/pages we list as gaps. - You refuse dual-use paths but still expect “military cyber” gravity.
- You need a local multi-stage GP — we profile angels and pre-seed, not mega-funds.
