# Nine Fives

> Nine Fives builds modern radio-frequency (RF) test equipment for manufacturers of wireless devices in cellphones, drones, and satellites. Founded by two former SpaceX engineers, the company replaces slow, driver-heavy legacy instruments with driverless, touchscreen, network-connected modules that share a single machine-readable API (REST and SCPI) and ship AI-readable documentation. The pitch: get RF test off the critical path and cut a hardware team's production-readiness timeline from months to minutes.

- **Founded:** 2025
- **Headquarters:** San Francisco, California, United States
- **Founders:** Noah Levy (Founder & CEO), Andrew Kurtz (Founder & COO)
- **Team size:** 2
- **Products:** POE-ATTEN-6G Programmable Attenuator, POE-SWITCH-6G SPDT RF Switch, Rack-mountable data & power backplane, NineVue web app, skill.md AI documentation
- **Notable:** Founders collectively spent about a decade at SpaceX designing RF hardware and test systems., Noah Levy was a six-time award winner at SpaceX and responsible engineer for the Falcon 9 Radar Altimeter and Dragon 2 S-Band Transceiver, and designed GPS and S-Band radios on Starship., Calibrated the largest phased array in SpaceX history.

## Products & services

- **POE-ATTEN-6G Programmable Attenuator** — A network-connected, touchscreen RF attenuator with an integrated display and a single machine-readable API (REST and SCPI). No vendor drivers required.
- **POE-SWITCH-6G SPDT RF Switch** — A driverless, networked SPDT RF switch with an integrated touchscreen, controllable over the same unified API as the rest of the Nine Fives line.
- **Rack-mountable data & power backplane** — Optional backplane that lets standalone modules snap into a shared power and data rack, enabling coordinated multi-instrument test setups.
- **NineVue web app** — A web application for generating easy-to-maintain, machine-readable rack configurations for a Nine Fives test setup.
- **skill.md AI documentation** — Machine-readable documentation shipped with the equipment so AI agents can understand the test system and write test software against it.
