Chennai-based underwater robotics startup Planys Technologies has raised ₹100 crore in a new funding round to fast-track its foray into defence, industrial inspection, and global offshore markets. The latest capital infusion assumes significance as the deep-tech company has gradually grown from an academic project to one of India’s most promising players in subsea robotics and asset integrity management.
Founded by alumni of the Indian Institute of Technology Madras and incubated at its incubation ecosystem, Planys has expertise in designing and deploying Remotely Operated Vehicles and Autonomous Underwater Vehicles that can perform inspection, maintenance, and other advanced marine operations. Since inception, the startup has earned a name for its homegrown technology that can operate in adverse underwater environments such as murky waters, deep-sea structures, and low-visibility industrial zones where human divers face extreme risks.
The newly raised ₹100 crore will be directed towards three strategic objectives:
It involves scaling manufacturing, deepening R&D, and expanding into defense-grade underwater systems. With geopolitical tensions around the world fuelling investments in maritime security, unmanned underwater systems for surveillance, mine detection, and infrastructure monitoring top the priority list of countries. Planys aims to leverage this momentum.
A key element of the company’s roadmap is to build an ultra-modern production and testing facility for underwater robotics. The facility will enable Planys to scale up its production manifold, necessary since demand is increasing from ports, oil and gas companies, power plants, desalination facilities, and naval agencies. Currently, the startup has deployments across more than 100 sites and has completed thousands of underwater inspection projects-encompassing dams, bridges, pipelines, and offshore platforms.
The indigenous line-up of ROVs from Planys is compact, modular, and capable of AI-assisted underwater inspections. Further, unlike traditional ROVs, which are bulky and expensive to maintain and operate, the company builds systems particularly suited for the conditions that prevail in India and emerging markets. These include low-visibility imaging, cloud-enabled reporting, swift mobility, and endurance suited to long-duration missions.
With defense becoming a key focus area, the startup plans to develop next-generation underwater drones capable of:
surveillance and reconnaissance,
hull and port inspections,
mine countermeasures,
environmental and seabed mapping, and
Communication-restricted navigation using advanced sonars and autonomy models.
The funding will also step up the development of industrial-grade AUVs, its vision of the next frontier in subsea tech. AUVs allow for long-range fully autonomous missions, which are ideal to be applied to such large, complex underwater infrastructures as offshore wind farms, river-crossing pipelines, and deep-sea renewable energy systems. As demand for clean energy grows, so does the demand for reliable underwater robotics that can help with constructing, monitoring, and maintenance.
India’s fast infrastructure development, especially in the cases of ports, bridges, hydro-power reservoirs, and coastal energy grids, has turned the country into a big market for underwater inspection solutions. Conventionally, such projects depend on imported foreign technology which is very expensive. Planys positions itself as a cost-effective, high-performance alternative, backed by indigenous innovation and domain expertise.
The company is also aiming for global expansion, mainly in the Middle East, Southeast Asia, and Europe. These regions represent huge opportunities in offshore oil and gas, sub-sea construction, and general naval operations. In addition, Planys’ focus on customization, quick deployment, and data-rich reporting places it in a very advantageous position in international markets dominated by far more expensive Western alternatives. Growth at Planys reflects the broader rise of India’s deep-tech ecosystem, where robotics, AI, and advanced manufacturing startups are accelerating from lab innovations to real-world applications. Amid the growing pressure on governments and industries to modernize underwater infrastructure and maritime security, companies like Planys emerge as strategic partners. With ₹100 crore of new capital, an expanding product suite and rising global demand, Planys Technologies is positioned to be a big name in the underwater robotics landscape, driving India’s technological leadership beneath the surface.
