Sheet 01 - Defence · Maritime · Industrial
16 years of systems that can't afford to fail - from Naval Simulators and Underwater Acoustics to the platforms that run Training Institutes, Repair fleets, Temples and School transport.
Sheet 02 - Products
Not concepts. Working systems with years at sea, in classrooms and on plant floors - and where something isn't in service yet, the card says so.
PRD-01 · SIMULATION
Action Speed Tactical Trainer
Scenario-driven tactical training for operators, watchkeepers and command teams. Radar, ESM/EW, passive and active sonar, fire control, AIS and configurable weather — deployable on-premise, on private cloud, or fully air-gapped.
In service
View system →PRD-02 · COMPLIANCE
Maritime Training Management
Course scheduling, certification tracking and audit-ready DG Shipping and STCW compliance records. Handles over 10,000 candidates and 3,000 courses annually, and has run inside India's largest maritime training institutions for over a decade.

View system →PRD-03 · ACOUSTICS
Paging that works where radio doesn't
Acoustic call-and-locate for metal-dense environments — ships, hospitals and industrial plants — where RF-based systems fail. Built on the same through-metal ultrasonic work that carries data across sealed bulkheads at up to 5 Mbps.

Beyond deep-tech, we build the AI-enabled ERPs and operations systems organisations live on daily - across domains most vendors would never attempt in one lifetime.
OPS / TRG
The platform behind NAMAC's maritime training operations — courses, candidates and certification records — running the compliance backbone of a national training body.

OPS / SVC
Aithertech ServiceOps: call intake to engineer-on-site for consumer electronics repair — scheduling, dispatch, parts and closure across five operational roles.
Read the case study →
OPS / COM
A Math's community platform and temple seva booking system — devotee records, bookings and offerings for an institution centuries older than software.

OPS / LOG
ArcaTrips: warehouse and school transportation management — routes, vehicles, and the daily accountability parents and operators depend on.

Sheet 04 - Capabilities
CAP / SIM
Physics-real maritime and multi-domain simulation: sonar and radar detection models, ship dynamics, HLA/DIS theatre-level wargames and scenario engines built from first principles.
CAP / GEO
PostGIS and TimescaleDB planning, tracking and analysis on real hydrographic and terrain data — fusing AIS, ADS-B, radar and IoT feeds. Open-source throughout, and deployable on closed networks.
Read more →
CAP / CTY
Utility and asset registries, transport planning, flood modelling and command-centre dashboards — the civil application of the same geospatial core, on the city's own hardware.
Read more →
CAP / IND
PLC, HMI and SCADA control, custom embedded hardware from PCB to enclosure, and industrial IoT with predictive maintenance — OT/IT-segmented, on the operator's own network.
Read more →
CAP / RF
FPGA signal processing, pressure-rated enclosures to 60 bar, custom antennas, and acoustic communication straight through steel at up to 5 Mbps.
CAP / AI
Retrieval-augmented generation over your own documents, LLM integration and fine-tuning, and document intelligence — running air-gapped, with no data leaving your perimeter.
Read more →
CAP / SW
Custom ERPs and operations platforms — HRMS, training, finance, field service — API-first, role-driven, AI-enabled where it earns its keep, and deployable on-premise or in your own private cloud.
Sheet 05 - Geospatial
Our geospatial work runs on open-source foundations - which is precisely what lets it run on a network with no route to the internet. The charts, tints and terrain above are real output from systems we built and run.
GEO / OSS
PostGIS, GDAL, QGIS, GeoServer, MapProxy and OpenLayers — the same stack national mapping agencies run on. No per-seat licences, no vendor lock-in, and source you can audit line by line. That auditability is not an ideological preference: it is the precondition for putting a system on a network nobody outside can reach.
GEO / AIR
Our GIS deployments carry their own basemaps, tiles and elevation data — GEBCO bathymetry, SRTM terrain, S-57 charts — served from inside your perimeter. Nothing calls a tile server on the public internet, because on a closed network there isn't one to call.
GEO / DAP
A shared, web-based common operating picture that fuses AIS, radar, ADS-B and sensor feeds into one plot, with combat and mission planning tools over the top. One source of truth across maritime, air, land and coastal domains.
GEO / CTY
The same geospatial core underpins urban work: utility and asset registries, transport and route planning, drainage and flood modelling, and command-centre dashboards that fuse municipal feeds. We are currently in discussion on smart city work for Ahmedabad, and we build this class of system to the customer's data and the customer's network.
Sheet 06 - From the founder
“We started Varuni in 2010 with one belief: hard problems deserve engineers who won't outsource the difficult parts. 16 years later, the Navy trains on our simulators, institutes certify on our platforms, and clients from our first years are still with us.”- Chaitanya · Director & Technical Lead
Start here
That's usually where we start. Write to us with the problem — not a spec — and we'll tell you honestly whether we can build it, how, and what a prototype would take. You'll hear back from an engineer, not a sales team, within two working days.
