Nine Fives: RF test equipment (YC Spring 2026), Skoor 40

Scoring basis: Skoor 40 from n=4 signals, confidence 0.8. All four signals come from the YC directory and were observed at the same time. [source]

What they built

Nine Fives makes RF test equipment for spacecraft, drones and cellphones. [source]

The company says it combines modern electronics, "AI ready test automation" and strategic supply chains so customers can cut time to market in half. [source]

Its GitHub org describes the product as "Simple, Networked, RF Test Equipment." [source]

Product specs, frequency range and pricing: not in the evidence.

Record

Measured signals (n=4):

In the YC Spring 2026 batch, status Active, stage Early. [source]

Team of 3, based in San Francisco, CA. [source]

Listed as hiring. [source] No specific roles appear in the evidence.

GitHub org created 2026-02-10. It shows 2 public repos, but no repo contents were captured. The org is unverified. [source]

Not in the evidence: founder names and backgrounds, funding, revenue, and customers.

Why now

The company frames the market as a $130B test equipment industry. [source] This is the company's figure, not an independent one.

Inference: demand for RF testing may be growing as spacecraft and drone production grows. No evidence here measures that.

Inference: the dataset tags this company as defense, but the YC listing tags only Aerospace, Telecommunications and Hard Tech. [source] No defense customer or program appears in the evidence.

Unknowns

Who the founders are and whether they have RF hardware experience.
Whether a working instrument exists, and at what performance level.
Whether any customer has paid or run a pilot.
What "strategic supply chains" means in practice.
What the 2 public repos contain.
What roles they are hiring for.

Questions for the room

You claim customers can cut time to market in half. Which customer measured that, on what test workflow, and against which incumbent instrument?
You list spacecraft, drones and cellphones. Which of the three has a paying or piloting customer today? Is any of them a defense program?
What specifically is "AI ready" about your test automation? Is it running on shipped hardware or still planned, and what is in the two public GitHub repos?

What would move the Skoor

Raises it: founder RF or test-instrument track records, named paying customers or defense pilots, and measured performance against incumbent equipment.
Lowers it: no working hardware, no customer conversations past demos, or a founding team without RF hardware experience.
