ESI Group
The Company

ESI is a pioneer and a major player at the global level in virtual prototyping that takes into account the physics of materials.

ESI has developed an integrated suite of coherent, industry-oriented applications that make it possible to realistically simulate a product’s behavior during testing, fine-tune manufacturing processes in accordance with the desired product performance, and evaluate the impact of the environment on product use. ESI’s solutions fit into a single collaborative and open environment for end-to-end virtual prototyping, so that physical prototypes can gradually be phased out during the product’s development phase.

With a presence in over 30 countries, ESI employs over 750 high-level specialists across its global network. The company generated revenue of €109.3 million and net income of €2.4 million in 2013.

ESI Group is listed on the C segment of NYSE Euronext Paris.
