SiPearl is a European semiconductor company focused on designing high-performance, energy-efficient processors for supercomputing and Artificial Intelligence (AI). Founded by Philippe Notton in June 2019, the company is bringing to life the European Processor Initiative (EPI) project with the goal of fostering European technological sovereignty in critical sectors like defense, security, health, energy, and climate. Their processors are designed to be backdoor-free and kill switch-free, contributing to a reduced carbon footprint. SiPearl's strategy involves close collaboration with over 30 partners from the EPI consortium, which includes scientific communities, supercomputing centers, and leading IT, electronics, and automotive companies. The company's first-generation processor, Rhea1, is based on the Arm Neoverse V1 platform and targets the EuroHPC Joint Undertaking ecosystem, aiming to enable European supercomputers to reach exascale power. SiPearl has secured significant funding, including a Series A round of €90m to launch Rhea1, with investors such as Arm, Atos Group (Eviden), the European Innovation Council (EIC) Fund, and the French State. They have also established key technological partnerships with Arm, Siemens Digital Industries Software, and Ansys, and manufacturing agreements with TSMC. SiPearl's first major customer contract is to equip the JUPITER exascale supercomputer.
