Praruh Technologies is an ICT system integrator that builds and maintains the hidden digital backbone - the routers, switches and fibre-optic links - that keeps India’s metro trains running and its public telecom networks connected. It was born as a private company in Noida and listed on the BSE’s SME platform in October 2025, after more than five years of executing complex infrastructure projects for government clients. The recurring approach is simple: win multi-year, milestone-based contracts from large public-sector customers, stitch together equipment from premier OEMs like Cisco and Nokia, and earn revenue at every stage - from design and supply through installation, testing and long-term maintenance. # Business segments A single project-based integration business serving India’s public-sector transport and telecom operators - every contract follows the same design-supply-install-maintain rhythm, just at different scales and locations. ## 1. Telecom & network integration: the digital plumbing for India’s public infrastructure **Praruh wins multi-year contracts to design, build and maintain the networking backbone for government metro and telecom operators, getting paid at every project milestone and then quarterly for years of upkeep.** - **Built on Cisco and Nokia gear** - the company integrates OEM technology from its premier partners, such as Nokia 7750 SR routers, into its customers’ existing networks, which means it does not need to invent its own hardware but instead earns fees for making proven equipment work together inside complex public systems. - **Paid as the project progresses** - contracts are structured so that cash arrives in stages: a percentage on successful installation and site testing, another on provisional acceptance, and the final slice on full handover, with supply-only items paid 100% on delivery and inspection. That milestone rhythm reduces the cash gap between spending and earning. - **Maintenance creates a recurring tail** - beyond the initial build, the company holds annual maintenance contracts (AMCs) that are billed quarterly, so a single project win can generate revenue for up to eight years after the installation is complete. - **Two anchor customers, many sites** - the business revolves around RailTel Corporation and Delhi Metro Rail Corporation, both government-owned, and the company is an empanelled partner of RailTel and Bharat Electronics Limited. Projects are deployed across West Bengal, Delhi, Telangana and Maharashtra, with one recent contract spanning 286 locations nationwide. - **The DMRC migration proves the technical ceiling** - the company migrated the signalling backbone of the Delhi Metro from legacy technology to IP MPLS (a modern networking standard that carries voice, video and data on one pipe) and upgraded the Airport Line stations, a reference job that demonstrates it can handle mission-critical public transport networks without disrupting live operations.
