Lachy Groom backs Indian startup aiming to keep aircraft aloft for a year

Prominent solo investor Lachy Groom has backed a Bengaluru startup attempting an ambitious feat: keeping an aircraft in the sky for more than a year by harvesting energy from ocean winds. Alteon, founded by 20-year-old Samay Sanghvi, announced Tuesday that it raised $2.5 million in a pre-seed round led by Groom, with participation from Together Fund, to develop autonomous aircraft inspired by dynamic soaring, a technique albatrosses use to extract energy from the wind.
