Founded by 20-year-old Samay Sanghvi, Alteon is pioneering autonomous aircraft that harvest ocean wind energy to remain airborne for months, backed by $2.5 million in pre-seed funding.
- Alteon raised $2.5 million in a pre-seed round led by solo investor Lachy Groom.
- The aircraft utilizes 'dynamic soaring' to extract energy from ocean wind shear.
- Initial applications focus on persistent maritime surveillance for governments.
- The startup operates a 10,000-sq-ft facility in Bengaluru with a team of 20.
In a bold bet on the future of aviation, prominent investor Lachy Groom has backed Alteon, a Bengaluru-based startup with a vision that sounds like science fiction: keeping an aircraft in the sky for over a year. Founded by the precocious 20-year-old Samay Sanghvi, the company recently secured $2.5 million in pre-seed funding, with participation from the Together Fund, to develop autonomous aircraft that mimic the flight patterns of nature's most efficient gliders.
The core of Alteon's innovation lies in dynamic soaring. Unlike conventional aircraft that rely on finite fuel tanks or heavy batteries, Alteon's fixed-wing autonomous drones are designed to extract energy from wind shear—the difference in wind speed at different altitudes above the ocean. By repeatedly diving and climbing through these layers, the aircraft can maintain speed and altitude indefinitely without traditional propulsion.
Why This Matters
BozokMedia analysis shows that this technology could disrupt the multi-billion dollar surveillance industry. Currently, persistent wide-area surveillance requires a costly rotation of satellites or fuel-hungry UAVs. An aircraft capable of staying aloft for a year would provide governments with an unprecedented, cost-effective, and real-time window into maritime activities, fundamentally altering border security and environmental monitoring.
"Ambitious problems are always going to come with risks, but I believe Samay and the Alteon team are the ones to figure them out." - Lachy Groom
The technical roadmap is aggressive. Alteon is currently building aircraft with a three-meter wingspan. The long-term goal is to integrate propellers that can act as turbines, converting excess wind energy into electricity to recharge onboard batteries, ensuring the aircraft remains powered even during periods of low wind shear.
However, the path to a year-long flight is fraught with engineering hurdles. Experts like Dr. Gabriel Bousquet and Dr. Bharath Swaminathan have noted that while the physics of dynamic soaring is established, the real-world application is treacherous. Operating within one meter of the ocean surface exposes the aircraft to extreme turbulence, salt spray, and unpredictable weather, requiring highly sophisticated sensors and rapid autonomous reactions.
Historical Background: Samay Sanghvi's journey began in 2023, immediately after high school. He spent months in a cycle of building and crashing radio-controlled models to understand the nuances of aerodynamics. This hands-on experimentation led to the formal founding of Alteon in 2025, supported early on by Emergent Ventures and 1517. Today, the team conducts over 200 test flights a month to refine their autonomous flight systems.
| Feature | Conventional UAVs | Alteon Autonomous Aircraft |

| Flight Duration | Limited (Hours/Days) | Extended (Months/Years) |
| Operational Cost | High (Constant Refueling) | Low (Passive Energy Harvesting) |
Frequently Asked Questions
1. Has Alteon proven the aircraft can fly for a year?
Not yet. They have successfully demonstrated autonomous flight cycles over the Bay of Bengal, but the next milestone is achieving 'energy-neutral' soaring where propulsion is entirely switched off.
The primary focus is maritime surveillance, providing real-time visibility into ocean activities for government agencies.
