Tonbo Imaging, a global leader in advanced defense technologies, has successfully raised ₹175 crore in its Series D pre-IPO funding round. The investment, led by Florintree Advisors, Tenacity Ventures, and Export-Import Bank of India, will support the development of next-generation infrared sensors and the commercial rollout of high-power microwave technologies for countering modern battlefield threats. The funds will also aid in scaling the company’s global operations and advancing ongoing programs.
This funding comes as Tonbo prepares for its upcoming IPO, marking a pivotal step in its strategy to capitalize on both organic and inorganic opportunities within the dynamic and rapidly growing C4ISR (Command, Control, Communications, Computers, Intelligence, Surveillance, and Reconnaissance) market. Tonbo Imaging, inspired by nature’s most efficient visual predator—the Dragonfly—designs cutting-edge sensing and processing systems to improve situational awareness, targeting precision, and autonomous battlefield operations.
Tonbo has previously secured over ₹300 crore from investors like Artiman, Qualcomm, Celesta, Edelweiss, and HBL Engineering. The company is now a trusted supplier of battle-tested systems, deployed by defense forces in more than 30 countries.
These include elite units such as the Israeli Defense Forces (IDF), U.S. Navy SEALs, NATO, Indian Ministry of Defense, and others. Tonbo’s technologies have supported major combat missions, including India’s URI surgical strike, IDF counterinsurgency operations, and the modernization of the Arjun Main Battle Tank.
Arvind Lakshmikumar, Founder and CEO of Tonbo Imaging, expressed his excitement about the funding: “Tonbo was founded with the vision of making high-end defense technology accessible. As the battlefield becomes more autonomous and agile, advanced sensors and non-conventional munitions will be the key technologies. This investment allows us to continue pushing the envelope on infrared imaging and directed energy solutions while scaling our global presence. Our goal remains to deliver state-of-the-art intelligence and protection systems to defense forces worldwide.”
Mathew Cyriac, Founder of Florintree Advisors, highlighted Tonbo’s potential, saying, “Tonbo Imaging is at the forefront of defense technology. Their expertise in imaging, artificial intelligence, and autonomous systems positions them well to tackle emerging global security challenges. We are thrilled to support Arvind and his team as they scale the business and build a world-class defense technology company from India.”
Rohit Razdan, co-founder of Tenacity Ventures, emphasized the importance of this investment: “Tonbo’s products, combining superior software with high-quality hardware, are gaining strong traction both domestically and globally. We believe Tonbo is poised to become a global leader in defense technology from India in the coming years.”
Tonbo Imaging specializes in advanced technologies that address the full spectrum of defense needs across land, air, and sea. The company’s vision is to enable battlefield autonomy through the integration of better sensors, real-time data, and comprehensive surveillance, reconnaissance, and targeting platforms. Tonbo’s products provide militaries worldwide with essential access to cutting-edge technologies, enhancing their operational capabilities.
