# Distributed Spectrum

> Distributed Spectrum builds AI-powered radio-frequency sensors and software that automatically detect, classify, and locate signals - drones, jammers, tactical radios, GPS spoofers - in real time. Founded by three Harvard engineers, the company packs commercial hardware and edge AI into sub-one-pound sensors that give soldiers and analysts persistent spectrum awareness without specialist RF expertise. It raised a $25M Series A in March 2025 and has fielded systems with US military branches and partners in Ukraine.

- **Founded:** 2020
- **Headquarters:** New York, New York, United States
- **Founders:** Alex Wulff (Co-Founder & CEO), Ben Harpe (Co-Founder), Isaac Struhl (Co-Founder)
- **Team size:** ~38 employees
- **Products:** AI RF Sensor Network, Edge AI Signal Detection Software, Soldier-Portable Detection Devices, Fixed-Site Spectrum Monitoring
- **Notable:** Raised an oversubscribed $25M Series A in March 2025, Secured ~$7M in DoD and intelligence-agency contracts in a single year, Won a $150,000 Indo-Pacific electronic-warfare competition

## Products & services

- **AI RF Sensor Network** — A mesh of small, ruggedized, sub-one-pound RF sensors built from commercial software-defined radios and Nvidia Jetson edge computers that autonomously detect, classify, and geolocate radio signals in real time.
- **Edge AI Signal Detection Software** — Machine-learning software that runs locally on each sensor to identify communications, jamming, drone-control, and GPS-interference signals and push real-time alerts without a human RF expert in the loop.
- **Soldier-Portable Detection Devices** — Handheld/wearable units that alert dismounted soldiers to approaching drones or nearby enemy cellular and radio activity.
- **Fixed-Site Spectrum Monitoring** — Stationary systems that continuously monitor the radio environment around military bases and critical sites for anomalies and threats.

## Achievements

- Raised an oversubscribed $25M Series A in March 2025
