In a statement Sophis says its founder and CEO Hervé Vinciguerra retains a "significant stake" in the company and will hold a non-executive role on the supervisory board.

Commenting on the new investment Vinciguerra says: "The arrival of a financial partner for Sophis at a key moment in its history will allow the company to accelerate its international expansion, especially in North America, where sales and professional services teams will be significantly strengthened."
