In early 2025, Harrison Rider LLC developed a concept of operations and go-to-market strategy for Echo — a lightweight, drone-mounted SIGINT system designed for front-line deployment. Built in partnership with Vannevar Labs, Echo brings tactical RF sensing to denied and degraded environments by integrating commercial drones, off-the-shelf SDR payloads, and AI-driven signal classification software. The engagement included CONOPS development, government customer mapping, and field deployment planning across INDOPACOM and CJADC2 networks. Echo is now positioned for $5M in DoD fielding opportunities and alignment with Army and Air Force procurement pathways.
