The European fabless designer of sovereign high-performance energy-efficient processors for HPC, AI and data centres

About us

SiPearl is the European fabless designer of sovereign high-performance energy-efficient processors for HPC, AI and data centres. These processors will help address strategic dual-use challenges in the fields of security, defence, medical research, energy, climate and engineering with a reduced environmental footprint. In June 2025, SiPearl completed the design of the most complex processor ever designed in Europe, Rhea1. Featuring 80 Arm Neoverse V1 cores, with 61 billion transistors, it is currently in production at TSMC in Taïwan and will be available for sampling in early 2026. Rhea1 processors will equip JUPITER, the first European exascale supercomputer owned by the EuroHPC JU and operated by the Jülich Supercomputing Centre in Germany. Incubated within the European Processor Initiative (EPI) consortium and seed-funded by the European Union, SiPearl employs 200 people in France, Spain and Italy. Following a successful €130 million Series A, the company is launching its Series B round.
