What Tridiagonal Solutions does

Tridiagonal Solutions is a privately held engineering consulting and experimental validation firm founded in 2006 as the first company incubated out of CSIR-National Chemical Laboratory (NCL), Pune, India, under the leadership of Dr. Vivek Ranade. The company delivers advanced modeling and simulation services — primarily Computational Fluid Dynamics (CFD), Finite Element Analysis (FEA), Discrete Element Method (DEM), and coupled multiphysics simulations — to process industry customers, alongside a Technology Validation & Scale-up Centre in Shirwal, India that operates one of Asia's largest integrated experimentation facilities (250,000+ sq.ft) for flow assurance testing, erosion/corrosion studies, and new energy validation from TRL 3 to TRL 9.

The company's core technology stack combines commercial CAE platforms (ANSYS, Star CCM+, LS-Dyna, Siemens Simcenter) with proprietary tools, including a CFD solver for mixing analysis (MixIT, launched 2013) and a simulation knowledge management solution (SimSight, launched 2022). Revenue is generated primarily through professional services engagements (project-based consulting) and software licensing/distribution partnerships, notably as the authorized distributor for GTT-Technologies' FactSage in India and APAC, plus strategic partnerships with Siemens Simcenter, Coreform, and Centers of Excellence with Honeywell, Emerson, Yokogawa, and Aveva. Customer segments span Oil & Gas (primary), Pharma & Medical Devices, Metals/Mining/Cement, Food/Beverages/CPG, Chemicals & Petrochemicals, and Power & Renewables, with 500+ customers globally including Fortune 500 process industry firms and 2,000+ projects delivered since founding.

Go-to-market is enterprise field sales targeting Fortune 500 process industry buyers through direct engagement, Lunch & Learn sessions at client sites, and conference participation (ICERSC, Hannover Messe), with a 150+ consultant team operating from offices in San Antonio (North America HQ), Pune (India HQ), Shirwal (lab facility), and Dubai (UAE). Tridiagonal has bootstrapped growth with minimal external capital (~$455K disclosed across two 2008-2009 funding rounds), launched the Tridiagonal.ai sub-brand in 2025 to pursue industrial AI applications, and rebranded in June 2024 with a new tagline 'Delivering Process Excellence.'
