Zeus Numerix

What Zeus Numerix does

Zeus Numerix Private Limited is an India-based computer-aided engineering (CAE) company founded in 2004 as a spin-off from the Aerospace Department of IIT Bombay and headquartered in Pune, Maharashtra. The company develops proprietary simulation software and delivers engineering services across computational fluid dynamics (CFD), finite element analysis (FEA), computational electromagnetics including Radar Cross Section (RCS) analysis, system modeling, scientific visualization, and machine learning applied to engineering problems. Its in-house software portfolio spans CFDExpert-Missile, CEMExpert, FanZ (axial fan design), GridZ (structured meshing), and ViewZ (post-processing visualization), as well as a WebAssembly/Emscripten-based browser platform for OS-independent CAE tool access.

The company operates in a vertical-focused B2B model, with primary customers being Indian defense and aerospace agencies (DRDO laboratories, ADA, the Indian Navy, the Indian Air Force) along with industrial manufacturers in fluid machinery, HVAC, heavy equipment, and ship classification. Revenue is generated through four streams: contract research and engineering services for defense labs, custom engineering software development, proprietary software products (including cloud-based tools through its Innovation Labs portal), and a growing line of build-to-specification defense products such as the FRP composite seawater pump, the SATEEK precision guidance kit, and the SLAM UAV weaponization kit. The company has CEMILAC certification for military airworthiness and participates in DRDO's Technology Development Fund scheme, and was selected to develop indigenous RCS software for India's Advanced Medium Combat Aircraft (AMCA) programme.

Go-to-market is enterprise field sales with direct engagement of government and industrial customers, supplemented by thought leadership through industry events (DefExpo, FICCI webinars) and an Innovation Labs web portal offering free online tools. Reported scale signals include 51-100 employees, 150+ clients served, 600+ projects delivered, and 35+ proprietary software tools developed and validated in cooperation with customers over a 20+ year history. The customer base remains concentrated in Indian defense accounts, with minor international engagements in the Republic of Korea and North America.
