Company Background
Tonbo Imaging India Ltd. was incorporated in 2003 as "Sarnoff Innovative Technologies Private Limited", based in Bengaluru. After working for over 20 years in the market, this company evolved from a private company to a publicly listed company in September 2025.
The company has transitioned from a specialized research entity to a global Original Equipment Manufacturer (OEM). Tonbo Imaging India Ltd.'s name and technology are inspired by the dragonfly's sophisticated vision system. Over the years, it has built a reputation for developing an independent intellectual property (IP), which allows it to compete effectively on the global stage.
Operations & Product Range
Tonbo Imaging India Limited builds high-tech cameras and imaging systems for defense and industrial use. They operate in a diverse range of products, from thermal binoculars to missile seekers, that are built to be compact and energy-efficient (Low-SWaP). As their technology is exempt from US export regulations (ITAR), it is easy to sell and ship their advanced tools to global customers.
Facilities & Capacity
Tonbo Imaging India Limited follows an "asset-light" model, focusing mainly on research and design. While their Bengaluru facility focuses on development, they outsource mass manufacturing to specialized partners. This approach helps them grow quickly without bearing too much cost in factories. They are currently expanding their testing facilities to handle a growing order book of over ₹266 crore.
Brands & Market Presence
The "Tonbo" brand is synonymous with high-end thermal imaging and sensor fusion. The company has a significant domestic and international footprint, having deployed over 20,000 systems across 24 countries, including the USA, Israel, and several NATO nations.
In India, it is a leading supplier to the government and defense agencies. Notably, the company accounted for approximately 93% of India's thermal imaging export volumes by units in Fiscal 2024 and 2025. This strong market presence is backed by various certifications and its role in critical national security missions.
Revenue Streams & Business Model
Tonbo Imaging India Limited earns money by selling systems directly to militaries, supplying parts to large manufacturers, and making components for global brands. Their revenue grew significantly from ₹96.83 crore in FY23 to ₹469.08 crore in FY25. While most of their sales come from exports, they have also achieved important contracts within India.
Management & Shareholding
Promoters & Shareholding
The promoters of the company are: Mr. Arvind Kondangi Lakshmikumar, Mr. Ankit Kumar, and Ms. Cecilia D'Souza. Mr. Arvind Lakshmikumar, the MD and CEO, holds a doctoral degree from Carnegie Mellon University and has over two decades of experience in imaging technologies.
Both Mr. Ankit Kumar (CBO) and Ms. Cecilia D'Souza (CCO) have 20 years of experience in their respective domains of research and finance.
Before the Tonbo Imaging India Limited IPO, the promoters and early investors held the majority of the equity, with the current OFS providing a partial exit for several venture capital backers.
Board & Key Management
The team is supported by a structured Board of Directors of visionary leaders. Ms. Sonal Shrivastava serves as the Chairman, while the board also includes Nominee Directors from key investor groups like Artiman Partners and independent directors who provide oversight on corporate governance.
