The breakup of the OFS includes 1,960,000 shares by Promoter Selling Shareholders, 339,700 by the Promoter Group, adn 15,635,046 by Investor Selling Shareholders.

Company profile and leadership

Established in 2003 by technologists with prior experience at the U.S.Department of Defense and Sarnoff Corporation, Tonbo shifted to defence-focused manufacturing in 2012 after a promoter-led buyout. The promoters are Arvind Lakshmikumar, Ankit Kumar and Cecilia D’Souza, who have steered the company for two decades, bringing deep expertise in global defence programs, engineering and capital markets.

Notable backers include Qualcomm Ventures, Artiman, Edelweiss Value, Celesta Capital II LP, HBL Engineering, Tenacity Ventures, India Exim Bank and Florintree.

Position in the defence tech landscape

According to the DRHP, Tonbo is among the fastest-growing defence technology players in India, measured by revenue, EBITDA, and PAT margin growth from FY23 to FY25, and it was the leading producer by sales value of thermal imaging systems supplied to government and defence agencies in the period.

By FY25, the company accounted for about 93% of india’s thermal imaging exports, underscoring its role as a major exporter in this niche.

What Tonbo builds and for whom

Tonbo designs, develops and manufactures sensing, processing, communications and guidance systems that are ITAR-free for surveillance, reconnaissance and targeting.It is evolving from standalone tactical kits to integrated autonomous platform solutions that fuse multiple hardware and software subsystems for battlefield use.

The product range spans from visible to long-wave infrared imaging and multi-sensor suites. It includes thermal imaging cores, weapon sights, handheld thermal imagers, targeting systems, missile seekers, fire-control and missile guidance systems-all aimed at enabling autonomous or semi-autonomous combat capabilities.

Technological edge and manufacturing model

tonbo emphasizes miniaturisation, low size, weight and power, modular payloads and AI-enabled image processing. Its applications cover remote weapon stations, ISR platforms, armoured vehicles and soldier-wearable systems, with a mission to augment, assist or, in some cases, replace human efforts on the battlefield.

The company claims 100% ownership of its IP across optics, software and electronics. It operates an asset-light approach, outsourcing fabrication to EMS partners such as Kaynes Technology India and Avalon Technology and Services, while keeping prototype development, system integration and qualification testing in-house.
