Planys Technologies is a technology company.
Planys Technologies specializes in submersible robotic solutions for critical underwater infrastructure inspection and survey. The company deploys Remotely Operated Vehicles (ROVs) with advanced non-destructive testing capabilities like HD videography and ultrasonic thickness gauging. This technology ensures precise data acquisition, enabling safer and more accurate evaluations of submerged assets for various industrial applications.
Co-founded in 2015 by Tanuj Jhunjhunwala, Prabhu Rajagopal, and Vineet Upadhyay, Planys originated from the insight that traditional underwater inspections were risky and imprecise. Leveraging their technical backgrounds, the founders aimed to apply robotics and AI, creating safer, more efficient methods for critical marine infrastructure assessment where human intervention is challenging or dangerous.
Planys' solutions serve operators of ports, terminals, and marine infrastructure. The company transforms asset management through a data-driven approach, providing comprehensive analytical dashboards for visualizing defects and informing maintenance strategies. Their vision is to establish new benchmarks for underwater asset integrity through continuous robotic and data intelligence.

Planys Technologies is an Indian deep‑tech company that builds underwater robotic platforms, non‑destructive evaluation (NDE) tools and AI analytics to perform remote inspection, monitoring and mapping of submerged infrastructure for industrial and defence customers[1][3].
High‑Level Overview
Planys develops compact remotely operated vehicles (ROVs), autonomous underwater vehicles (AUVs), an Internet‑of‑Underwater‑Things stack and an AI‑enabled dashboard to deliver underwater inspections, surveys and condition‑monitoring as a service to ports, oil & gas, power/dams, rail/bridges, shipping and defence customers[1][3][2].The company’s value proposition is to replace risky, slow and often incomplete diver‑based inspections with unmanned, repeatable and digitally documented inspections that reduce downtime, improve safety and enable predictive maintenance for high‑value submerged assets[1][3].Planys has completed hundreds of projects and thousands of inspection hours globally, and it positions itself as one of India’s pioneer underwater robotics firms incubated at IIT Madras[1][3][2].
Origin Story
Planys was founded out of research at IIT Madras (incubated there) by team members including IIT alumni Tanuj Jhunjhunwala and Vineet Upadhyay with roots in projects beginning around 2012 and formal company registration in 2015[2][3].The idea emerged to address the lack of reliable underwater diagnostic capability—where manual diver inspections were unsafe or inadequate—by combining marine robotics, advanced NDE sensors and analytics to produce actionable inspection reports; early traction included pilot inspections for industrial customers and successive productization of ROVs, AUVs and software[3][1].
Core Differentiators
Role in the Broader Tech Landscape
Planys rides the trends of robotics/autonomy, industrial IoT and digital twins for infrastructure—areas gaining traction as operators seek condition‑based maintenance and remote asset visibility to cut costs and risk[1][3].Timing matters because aging infrastructure, tighter safety/regulatory expectations, and heightened focus on domestic defence capabilities create demand for reliable underwater inspection tech, especially in markets that historically lacked local suppliers[3][1].Market forces in their favor include increasing capex for ports/energy, rising adoption of predictive maintenance, and national initiatives to indigenize critical defence and maritime technologies[3][2].By building an end‑to‑end ecosystem (robotics + NDE + analytics), Planys helps professionalize underwater inspection practices and raises standards for data‑driven asset management across sectors[1][3].
Quick Take & Future Outlook
Planys is likely to keep expanding across civil, energy and defence verticals while deepening software and analytics monetization (subscription or service contracts) and scaling exports as credibility grows from case studies and IP[3][1].Key trends that will shape its path are broader adoption of autonomy in marine operations, tighter regulatory emphasis on asset integrity, and defence modernization programs that prioritize indigenous systems—which together create sizable market opportunity but also invite competition from established marine‑robotics players[3][1][4].If Planys sustains product reliability, service quality and international certifications, it can strengthen its role as a regional leader in underwater inspection and contribute to shifting industry practice from ad‑hoc diver checks to continuous, data‑driven monitoring[1][3].
