Ornadyne

match 48

Ornadyne builds flapping-wing drones for reconnaissance that look, fly, and sound like birds. Today’s drones are easy to detect acoustically, visually, and electronically. As counter-UAS systems improve, traditional quadcopters and fixed-wing UAS systems are becoming increasingly ineffective for close-range surveillance. Flapping-wing aircraft have existed for years, but have lacked the performance, endurance, and control required for real-world deployment. We’re changing that by engineering a h

Perseus Defense

match 45

Perseus Defense is building a mass-manufactured Counter UAS solution for the Department of Defense and Department of Homeland Security. Current solutions are one-to-one, too dangerous for use on U.S. soil, and orders of magntiude more expensive than the threats they defeat. Our self-guided missile platform is man-portable and multi-domain capable. It senses, engages, and eliminates threats with drastically reduced cost per engagement over existing kinetic solutions. Solving this critical nationa

Arlo Industries

match 43

Arlo Industries is building a network of sensors that precisely tracks stealthy drones and aerial threats better than radars. This capability does not exist yet because traditional radars are built on past war doctrines designed to protect single, centralised assets. Modern warfare, however, demands wide-area, persistent coverage that is both passive and economically scalable. By utilising a mesh architecture, Arlo Industries unlocks unprecedented asymmetric economics. The network is fundamental

Tule

match 36

Tule helps farmers make irrigation decisions. Using UC Davis research-based technology, our hardware sensor provides growers with field-scale crop water use measurements (i.e., actual evapotranspiration), crop water stress measurements, applied irrigation measurements, and irrigation recommendations. Using the latest AI technology and our unprecedented crop water stress dataset, our latest product, Tule Vision, provides growers with the water stress of their plants just by taking a picture with
