Robotics Startup AquaAirX Secures ₹12.5 Crore Funding from Rainmatter and Others

AquaAirX, a Bengaluru‑based robotics startup that builds amphibious drones, announced a ₹12.5 crore financing round on January 28, 2026.  

The round was led by Rainmatter, the investment arm of Zerodha, and included Prime Venture Partners, Wyser and India Accelerator. 

Funding Details and Investor Participation 

The ₹12.5 crore injection will support AquaAirX’s core technology development and team expansion. Rainmatter highlighted the startup’s systems‑level approach to multi‑domain autonomy, while other investors were attracted by the potential to replace separate air and underwater platforms with a single solution. 

Technology Focus and Product Development 

AquaAirX is creating unmanned platforms capable of transitioning from aerial flight to underwater operation without manual intervention.  

The technology aims to deliver continuous intelligence, surveillance and reconnaissance (ISR) with reduced response time and operational risk.  

In addition to the amphibious drone, the company is developing a Hovering Autonomous Underwater Vehicle (HAUV) for precise inspection and intervention tasks.
