Aloft Sensing

Why it fits

A radar NASA puts at seven kilograms that positions itself without GPS fits long-endurance stratospheric surveillance. Task orders funded by the Air Force Research Laboratory through NASA Ames pay for demonstrations on the BAE PHASA-35 and Aerostar Thunderhead balloon.

Stage and round

No venture round was found: EDGAR searches return no match and no page opened names an investor. USAspending lists eight contracts starting between January 2022 and September 2025 totalling $5,806,113.94, plus three NASA grants totalling $8,763,972. The SAM record (mirrored) gives a start date of 5 November 2019. The FCC granted three special temporary authorities for radar operation at 55 to 75 kft from 8 to 30 September 2026.

Ask on the first call

1. 01Per USAspending, AFRL funds the four NASA Ames task orders. Who is the sponsor inside AFRL, and is there a path to a production or programme-of-record buy?
2. 02What happened on the September 2026 stratospheric flight covered by the three FCC authorities: which platform, how long aloft, and did SAR, InSAR and MTI perform to specification?
3. 03The August 2026 FCC exhibits show a custom Aloft transceiver with an EMAG Technologies antenna. What does Aloft own in the hardware stack, and at what unit cost?
4. 04The SAM record gives a November 2019 start and USAspending awards begin in January 2022. Is the company seeking outside capital, and what would it be used for?

Risks

• –All funding found is federal (about $14.6M). No non-government customer appears in any source, and the 2026 FCC exhibits say the imagery and data will not be sold commercially.
• –The radar depends on stratospheric platforms built by others (BAE's PHASA-35, Aerostar's Thunderhead balloon, airships), so demand is tied to third-party HALE programmes reaching operational use.
• –Small team (LinkedIn lists 2 to 10 employees) and no equity round found since 2019. It may not want venture capital or may be run as a contract R&D business.

Could not confirm

• ?A search summary attributes an Andreessen Horowitz seed and Series A to Aloft Sensing. No page opened supports it, and it most likely refers to a different Aloft.
• ?NASA says the instrument was validated aboard an airship at 65,000 feet and on small stratospheric balloons, but gives no dates, platform names or results. Not independently confirmed.
• ?The company claims micron-level localization and picosecond timing on its site and LinkedIn page. No independent test result was found.
