Planys Technologies, a Chennai-based deep-tech startup, has raised ₹100 crore in primary funding led by marquee investors Ashish Kacholia and Lashit Sanghvi, with participation from existing investors including Pratithi Investment, Samarthya Investment Advisors, 3i Partners, Letsventure and angel investors.
The round also enabled exits for Planys’ earliest supporters, reflecting strong value creation since inception.
The fresh funds raised will be used to scale its industrial inspection business across global markets and accelerate its fast-growing defence technology roadmap through its newly created subsidiary, Planys Ark.
Founded in 2015 by Tanuj Jhunjhunwala and Vineet Upadhyay, Planys Technologies is an Indian deep tech company specializing in marine robotics and underwater inspection solutions.
Its proprietary platforms are engineered for environments that have historically remained inaccessible, from ultra‑turbid water to complex structural testing applications in marine and industrial structures.
Planys holds 21 granted patents with an additional 15 patents filed, highlighting its strong innovation and deep IP portfolio.
The company uses Remotely Operated Vehicles (ROVs) and intelligent data analytics to inspect and maintain submerged assets. Planys is headquartered in Chennai, India, and has offices in other countries.
Planys is advancing a new generation of underwater robotic systems, using hybrid ROVs and robotic crawlers, as well as an AI‑powered 3D Inspection Twin for advanced testing of critical infrastructure.
Planys’ product portfolio covers a wide range of ROVs and AUVs, including micro AUVs for expendable use cases. Planys has also developed indigenous propulsion systems that power its product lines, reducing future dependence on foreign OEMs for mission‑critical applications such as mine countermeasures, ISR, and expendable missions.
Planys’ upcoming internationally certified, explosion‑proof ROV TankRover enables in‑service inspection of hydrocarbon storage tanks, boosting safety, increasing inspection frequency, and cutting downtime and costs.
With more than 25,000 hours of successful operational deployment across 500 sites in 10+ countries serving 150+ users, Planys has built a robust global track record across Singapore, Brunei, Saudi Arabia, the UAE, Qatar, Oman, and the Netherlands.
The company’s clientele includes industry leaders such as Reliance Industries, IOCL, BPCL, MSRDC, Indian Railways, ExxonMobil, Shell, Saudi Aramco, and SABIC. Planys raised ₹43 crore in April 2024 in an equity infusion led by Ashish Kacholia.
Planys is expanding its international footprint through strategic partnerships. Its collaboration with Applus Velosi in Qatar unlocks high‑value industrial clients, while HUB71’s global deep‑tech cohort in Abu Dhabi links pathways to the regional and global ecosystem.
Tanuj Jhunjhunwala, CEO & Co‑Founder, Planys, said, “This capital infusion marks a pivotal step in Planys’ journey. This enables us to enhance our solutions for some of the world’s largest organisations, while concurrently developing India’s next generation of unmanned underwater systems. Through our defence arm – Planys Ark, we are intensifying our focus on high-impact defence opportunities.”
Vineet Upadhyay, CTO & Co‑Founder, Planys, said, “With Planys Ark, we are fast-tracking a new generation of indigenous underwater systems designed to elevate India’s defence capability to global standards. Our fully India-built technologies enable mission-ready, customisable UUV solutions for complex and evolving operational scenarios. To support this expansion, we intend to build a state‑of‑the‑art unmanned underwater vehicle (UUV) production facility in South Chennai, featuring advanced fabrication and underwater testing infrastructure.”
Lead investor Ashish Kacholia, who has doubled down with a fresh investment, said, “Planys has demonstrated exceptional technology depth and strong commercial traction. Its in-house platforms uniquely position the company to lead across industrial and defence applications.”
