About SiPearl

SiPearl is the European fabless designer of sovereign secure high‑performance energy‑efficient CPUs for HPC, AI and data centres. These CPUs help address strategic challenges in security, defence, medical research, energy, climate and engineering with a reduced environmental footprint. In June 2025 the company completed the design of the most complex CPU ever designed in Europe, Rhea1, featuring 80 Arm Neoverse V1 cores and 61 billion transistors, currently in production at TSMC. SiPearl CPUs will equip the two first European exascale supercomputers of EuroHPC JU: Rhea1 in the JUPITER machine in Germany and Rhea2 in Alice Recoque in France. Incubated within the European Processor Initiative consortium and seed‑funded by the European Union, SiPearl employs almost 200 people in France (Maisons‑Laffitte, Grenoble, Massy, Sophia Antipolis), Spain (Barcelona) and Italy (Bologna). Following a €130 million Series A, the company launched its Series B round.
