Success stories:


Kalray is the pioneer in processors for new smart systems. A real technological discontinuity, “smart” processors have the capability to analyse on the fly and in an intelligent manner, a very large amount of information, and to make decisions and interact in real time with the outside world. These smart processors will be deployed extensively in fast-growing sectors such as new-generation networks (smart data centres) and autonomous vehicles, as well as healthcare equipment, drones and robots. After a Pre-IPO round of €10m early in 2018 backed by Definvest, Kalray raised €47.7m on the Euronext Growth index in June (an all-time record for an IPO on Euronext Growth). By the end of 2018, Kalray entered a partnership with NXP to develop a platform for safe, reliable autonomous driving.


SinterMat is a specialist in spark plasma sintering (powder metallurgy). Backed by Definvest in a seed round of €3m, it aims to quickly become the first industrial provider of spark plasma sintering pieces for the Luxury, Aerospace & Defence industries in Europe.
