Lachy Groom, the Notion co-founder known for backing ambitious moonshots, has invested in an Indian startup with a premise that sounds like science fiction: an aircraft that stays aloft for an entire year without landing. The funding round propels a small team chasing a category that has defeated better-capitalized programs before.
The company is developing high-altitude, solar-electric platforms designed to cruise in the stratosphere, where sunlight is near-constant and weather systems pass below. The goal is endurance measured in seasons rather than hours: aircraft that function as reusable satellites-in-waiting, carrying communications relays, imaging sensors or climate instruments. Persistent flight, the founders argue, offers a satellite's reach with an aircraft's repairability - a vehicle can be guided home, serviced and reflown.
Perpetual flight is an old dream with a graveyard behind it. Solar prototypes have crossed oceans and set multi-day records, but year-long continuous operation remains unsolved, demanding breakthroughs in energy storage, lightweight structures and autonomous flight control that tolerates months without human intervention. India's angle is cost: the startup claims its engineering approach and local manufacturing could deliver endurance platforms at a fraction of aerospace incumbents' budgets.
Groom's involvement reflects a broader investor drift toward physical-world moonshots - stratospheric communications, persistent surveillance and disaster response all map to defense and enterprise demand. The startup says it will use the fresh capital to extend flight tests toward its first hundred-day mission, a milestone that would separate serious contenders from slide decks. A full year in the air, on the other hand, may take the decade to prove.
