Tonbo Imaging, a leading defense technology firm based in India, has secured ₹175 crore in a Series D pre-IPO funding round. The investment was led by Florintree Advisors, Tenacity Ventures, and the Export-Import Bank of India.
The fresh capital will help the company develop next-generation infrared sensors and expand the use of high-power microwave systems designed to counter emerging threats on the battlefield. It will also support Tonbo’s global expansion and further the progress of its ongoing defense programs.
This funding comes as Tonbo moves closer to launching its initial public offering (IPO). The company sees the IPO as a key part of its broader strategy to grow in the fast-evolving C4ISR sector—Command, Control, Communications, Computers, Intelligence, Surveillance, and Reconnaissance.
Tonbo Imaging, named after the dragonfly—a symbol of visual precision—designs advanced sensing systems to enhance military awareness, targeting, and autonomous operations in combat zones.
To date, the company has raised over ₹300 crore from earlier investors such as Artiman, Qualcomm, Celesta, Edelweiss, and HBL Engineering. Tonbo is now a trusted supplier of defense systems, with its technology used by armed forces in more than 30 countries.
Its clients include major military organizations like the Israeli Defense Forces (IDF), U.S. Navy SEALs, NATO, and the Indian Ministry of Defense. Tonbo’s equipment has been used in several major operations, including India’s 2016 surgical strike in Uri, IDF counterinsurgency missions, and upgrades to India’s Arjun Main Battle Tank.
Commenting on the latest funding, Arvind Lakshmikumar, Founder and CEO of Tonbo Imaging, said,
“Tonbo was started with the goal of making high-end defense technology accessible. As warfare becomes more agile and autonomous, advanced sensors and non-conventional weapons will shape the future. This investment allows us to keep innovating in infrared imaging and directed energy while scaling our operations globally. We remain committed to delivering the best protection and intelligence systems to defense forces around the world.”
Mathew Cyriac, Founder of Florintree Advisors, expressed strong support for the company’s vision.
“Tonbo is a leader in defense technology. Their work in imaging, AI, and autonomous systems positions them well to tackle today’s complex security challenges. We’re proud to support Arvind and his team as they expand and build a global defense tech powerhouse from India.”
Rohit Razdan, Co-founder of Tenacity Ventures, added,
“Tonbo’s mix of high-quality software and hardware is gaining traction both in India and abroad. We believe the company is well-placed to become a global leader in defense technology in the years ahead.”
Tonbo Imaging develops technologies for land, air, and sea-based defense operations. Its mission is to enable greater autonomy on the battlefield by combining real-time data, advanced sensors, and full-spectrum surveillance and targeting platforms. The company aims to equip modern militaries with the tools they need to enhance operational readiness and mission success.
