Revenue model

1. Software Licensing (GT-SUITE / Exothermia Suite): Simulation software sold as part of the GT-SUITE platform under Gamma Technologies. Exothermia Suite provides exhaust aftertreatment system simulation capabilities as a specialized module within the broader GT-SUITE product ecosystem. Revenue is generated through software licenses to automotive, marine, and industrial engineering companies.
2. Engineering Services and R&D: Exothermia provides specialized engineering consulting and R&D services, including model-based design and optimization of exhaust aftertreatment systems, battery systems, and powertrain electrification. Services are co-funded through EU/Greek government innovation programs (ERDF, EEA Grants, Research-Create-Innovate), which partially subsidize development costs.

Core offering

Exothermia develops physics-based simulation software for exhaust aftertreatment systems and battery technologies, sold as the 'exothermia suite' module within Gamma Technologies' GT-SUITE platform. The software models catalytic reactions, heat and mass transfer, particulate filtration, and multi-scale battery behavior for automotive, marine, and industrial OEM/engine manufacturers. The company also delivers specialized engineering consulting and co-funded R&D services covering emissions control, powertrain electrification, thermal management, and fleet electrification analysis.

Product overview

Exothermia Suite is a single unified exhaust aftertreatment system simulation product offered as part of Gamma Technologies' GT-SUITE portfolio. It provides industry-proven solutions including catalytic reactions, heat and mass transfer, filtration modelling, and comprehensive E.A.T. engineering tools spanning from early concept phase to mass production.

Broad incumbents

• Gamma Technologies: Gamma Technologies develops GT-SUITE, the multi-physics CAE platform within which Exothermia Suite is sold. While formally a distribution partner, GT is the most directly comparable firm — same customer base (automotive, marine, industrial OEMs), same simulation domain (powertrain, aftertreatment, battery, thermal), but at vastly greater scale and with a broader product portfolio.
• Siemens Digital Industries Software (Simcenter): Siemens' Simcenter portfolio (including former CD-adapco STAR-CCM+) covers combustion, emissions, aftertreatment, and battery thermal simulation across automotive, marine, and industrial markets — a broader incumbent offering overlapping with Exothermia's core domains.
• ANSYS: ANSYS provides multiphysics simulation (Fluent, Maxwell, Mechanical) widely used for exhaust aftertreatment, thermal management, and battery analysis at OEMs and Tier-1s. Its scale and horizontal CAE footprint make it a competing alternative for the same engineering budgets Exothermia targets.
• Dassault Systèmes (SIMULIA): Dassault's SIMULIA Abaqus/CST/SIMPACK suite addresses structural, thermal, and multiphysics simulation at automotive OEMs, including powertrain electrification and battery applications — a broad incumbent whose customer footprint overlaps substantially with Exothermia's.
• Altair Engineering: Altair provides CAE software (HyperWorks, MotionSolve, ultraFluidX) used across automotive and industrial simulation workflows, with growing presence in EV battery and thermal management — addressing the same OEM engineering teams as Exothermia.

Direct peers

• AVL: AVL is the leading independent powertrain and vehicle simulation company (CRUISE M, FIRE M, EXCITE), directly competing with Exothermia in exhaust aftertreatment, powertrain electrification, and battery simulation for OEMs. AVL's larger scale and in-house test-cell infrastructure make it the most direct strategic competitor.
• Convergent Science: Convergent Science's CONVERGE CFD software is widely used for combustion and emissions-aftertreatment simulation in automotive and marine engines, addressing the same customer workflows (DOC/SCR/DPF modeling, virtual calibration) that Exothermia targets.
• MathWorks: MathWorks' MATLAB/Simulink is the dominant engineering simulation environment at automotive OEMs and overlaps with Exothermia's xiL integration and model-based control development offerings. Customers frequently evaluate MATLAB-based toolchains against Exothermia's GT-SUITE module.
• Ricardo: Ricardo (including its IGNITE simulation suite) provides powertrain, vehicle, and aftertreatment simulation services and software to OEMs, directly comparable to Exothermia's combination of physics-based simulation tools and engineering services.

Others

• Emisia SA: Emisia SA is a Greek fleet emissions and electrification analytics firm that co-developed the HealthyFleet solution with Exothermia. While not a direct simulation competitor, Emisia is a closely adjacent peer in fleet-level transport decarbonization analytics and a co-development partner.
