SURSUM-MI S.R.L.

Politecnico di Milano has been for decades one of Europe's leading research centers in mechanical and thermodynamic engineering. Sursum-MI is the spin-off that chose to bring outside the university's laboratories twenty-five years of specialization in the development of 1D codes and CFD (Computational Fluid Dynamics) models for internal combustion engines and fluid machinery — deep technical expertise with concrete applications in the automotive, aerospace, and industrial machinery sectors. 1D codes and CFD models are simulation tools that allow the behavior of engines and fluid systems to be analyzed computationally, reducing the need for costly physical prototypes and accelerating development cycles. In a sector like automotive, where the optimization of powertrains — both thermal and hybrid — requires ever-faster development cycles, access to accurate and validated simulation models is a concrete competitive advantage. Sursum-MI operates in a technically specialized niche market, with clients typically including major automotive OEMs, first-tier suppliers, and aerospace companies that need accurate simulations for the development of their products. The B2B model focused on custom solutions reflects the nature of the work: every simulation is built on the specific requirements of the client's problem, and the technical expertise of the team is the primary asset. The energy transition in the automotive sector — with the progressive electrification of vehicles — does not make Sursum-MI's expertise obsolete: hybrid architectures still require optimized management of the thermal engine, and industrial fluid machinery remains central in sectors that will not electrify easily. The knowledge base accumulated over decades of applied research represents a defensible advantage in a market where the learning curve is very steep.
