About Arcani
Arcani is building next-generation passive sensing systems for modern defence environments. Our flagship platform, HARK (Hostile Acoustic Recognition Kit), is a low-cost, omnidirectional acoustic drone detection system designed to detect and classify drones in contested environments, including RF-silent and autonomous threats. Our systems integrate with platforms such as ATAK, Lattice, and emerging NATO interoperability standards including SAPIENT. Arcani is currently working alongside defence partners, NATO programmes, and operational end users across the globe.
