Sea Machines is the self-driving boat company. We are improving the sailor's experience on water by making boating safer and easier. FOR TRADITIONAL MANNED VESSELS Our self-driving technology will be used to increase the safety of boating via autonomous self-navigating systems that keep sailors and their passengers out of harms way. Think of it as a very smart auto-pilot that has full control of the boat while avoiding all charted and dynamic obstacles. FOR THE NEW CLASS OF UNMANNED VESSELS The technology can also be used to control unmanned vessels from a remote location. We give the ability to operate a boat in an unmanned mode via direct joystick remote control or provide drive-by computer autonomy for local or over-the-horizon navigation. We are currently testing our fully driverless solution in Boston Harbor and we're looking for smart, ambitious people to help change a major segment of the transportation industry with cutting edge autonomous technology.

Elroy Air is enabling autonomous air transport anywhere. We are developing autonomous aircraft systems to deliver goods to the world’s most remote places. Building on the powertrain and perception technology enabling the hybrid-electric/autonomous vehicle revolution, our vertical-takeoff-and-landing (VTOL) cargo transport system can operate outside of airport infrastructure and carries 200+ lbs over 300 miles. Immediate aid and relief in disaster and firefighting situations, commercial cargo by air to expand delivery options, and rapid autonomous resupply for troops in the field. Our flight and ground operations make Elroy Air's vehicles a safe, reliable, efficient way to transport cargo by air.
