About us

Culgi B.V. is an international IT software services company, specializing in computational chemistry. Culgi B.V.’s tools are used to calculate formulation processes and to develop specialty chemicals. The company is also active in the areas of drug development and drug design.

Culgi B.V. employs computational scientists, physical chemists, and software engineers, working from Leiden, The Netherlands. The company commands a vast network of application scientists from all over the world to provide international support and consultancy services. 

The company was founded in 2004 and has since then been sponsored by chemical industry, oil industry, personal and home care industries and pharma companies. The company also participates in national and international (EU) government-sponsored projects.

The founder and Chief Science Advisor of CULGI, professor Johannes (Hans) Fraaije, invented the first mesoscale dynamics code for polymer blends phase formation in 1990 (now known as Mesodyn), while working at the Department of Applied Mathematics at Akzo Nobel R&D. Since that early contribution, professor Fraaije has been instrumental in defining industrial applications of computational chemistry, in a myriad of projects, both in academic and commercial roles. His current interest is in the broader aspects of digitalization of chemical R&D, in particular, the position of computational chemistry as an add-in to IP protection.

Dr. Jan-Willem Handgraaf is Chief Operating Officer of CULGI and serves to manage all aspects of operations and project definitions. Dr. Handgraaf has a Ph.D. in computational chemistry from the University of Amsterdam and has been involved with CULGI since its inception.

“The Culgi framework has become an essential tool for the teams atomistic, molecular and mesoscale simulations. The Fraunhofer Institute for Manufacturing Technology and Advanced Materials (IFAM, Bremen) conducts industrial research in the fields of adhesive bonding, coating and surface technology as well as in composite materials.”
