Gamma Technologies, LLC

Gamma Technologies develops, markets, and sells engineering simulation software called GT-SUITE. With roots in the automotive industry, GT’s software is leveraged by nearly all the world’s leading automotive manufacturers. Our solutions help automotive companies build more fuel-efficient vehicles that get better gas mileage and reduce emissions without sacrificing vehicle performance. The move from traditional internal combustion engines (ICE) powered by gasoline or diesel fuel to electrified vehicles presents an enormous market opportunity for GT as our software allows Electrical Vehicle manufactures and their suppliers to design better vehicles. Regulatory agencies globally have mandated that vehicle manufacturers reduce harmful environmental emission output, or they will face significant financial penalties and GT helps our clients meet these mandates.

In addition to the automotive industry, GT serves the aerospace, HVAC and marine industries.
