Bengaluru-based defense technology firm Tonbo Imaging has raised Rs 175 crore or $21 million in its Series D pre-IPO round from Florintree Advisors, Tenacity Ventures, and the Export-Import Bank of India.
The proceeds will be used to support the company’s development of next-gen infrared sensors and advanced energy weapons, along with expanding its global operations.
Founded by Arvind Lakshmikumar, Tonbo Imaging blends optics, AI, and computer vision to create advanced surveillance and targeting systems that work across land, air, and sea. Its focus is on building lightweight, autonomous platforms that can operate in harsh battlefield conditions.
Tonbo Imaging builds high-tech vision and targeting systems used in military operations worldwide. Its products enhance battlefield awareness and are already used in over 30 countries by forces like the U.S. Navy SEALs, Israeli Defense Forces, NATO, and the Indian Army.
With over Rs 300 crore raised in previous rounds from investors like Qualcomm and Edelweiss, Tonbo is now gearing up for its IPO.
