About us

Rafinex was formed by people who believe that advanced mathematics can bring so much more impact to engineering. By combining best-in-class algorithms and AI-assistance when needed, we are striving to find and provide the world’s most advanced and most appropriate numerical methods for your challenging needs - ready to use and packaged as cloud simulation apps with built-in expert know-how.

Rafinex goes beyond current market tools by accounting for real-life variability using uncertainty quantification methods and by considering manufacturability; allowing safe and profitable usage by everyone in engineering design.

The team

André A. R. Wilmes, PhD
Chief Executive Officer

André Wilmes has developed numerical methods for simulating composite nano-materials at Imperial College London and has given guest seminars at leading research centers including NASA and TU Munich.

He has experience as an R&D project manager in the ceramics and manufacturing industries, where he developed new simulation methods and experimental prototype processes in a variety of material topics ranging from fracture mechanics to optics.

Johannes Neumann, Dr. rer. nat.
Chief Science Officer

Johannes Neumann researched physical simulations with stochastic uncertainties and robust topology optimization at the Weierstrass Institute for Applied Analysis and Stochastics (WIAS) in Berlin.

His focus on accelerating the numerical calculation unlocked the practical applicability of stochastic methods in a business environment. He has a wide network of scientific contacts across Europe in the field of numerical mathematics.

Abeed Visram, PhD
Chief Technology Officer

Abeed Visram specialized in high-performance computation of fluid dynamics (CFD) at Imperial College London. His collaboration with the UK Meteorological Office investigated the numerical stability of long-term weather forecasts in which the smallest numerical inaccuracies distort the forecast.

Subsequently, he worked on simulation automation in the CFD Technology department of McLaren Racing Ltd before joining Spirable Ltd as Head of Innovation and cloud architect.


Rafinex is a spin-out company formed from a project hosted at the Weierstrass Institute for Applied Analysis and Stochastics. The project is funded by the EXIST program of the Federal Ministry of Economic Affairs and Energy and the European Social Fund, with the guidance of the Leibniz Association, under the title rDesign: Robust Topology-Optimization for SMEs in Industry 4.0.
