Manufacturing Startups To Watch: 5 Startups That Caught Our Eye In September

Alteon is a Bengaluru-based aerospace startup developing autonomous aircraft that fly using dynamic soaring, rather than traditional propulsion. These aircraft can stay airborne for extended periods, making them ideal for monitoring oceans, borders, and remote infrastructure. Currently operating in India's UAV market, valued at $470 million in 2025 and projected to reach $1.39 billion by 2030, Alteon's technology is being applied to defense and surveillance use cases.

The company recently completed an offshore flight test, demonstrating its ability to autonomously fly consecutive loops within a meter of the ocean surface. Looking to the future, Alteon aims to develop aircraft that can remain airborne for over a year, enabling continuous monitoring of illegal activities such as fishing and drug trafficking.
