SiPearl completed its €130 million Series A funding round. The final closing included a new €32 million tranche. Taiwanese Cathay Venture, EIC Fund, and France 2030 led the investment.
The total €130 million Series A represents the largest in the European fabless semiconductor industry. This funding supports the industrialization of Rhea1, SiPearl's flagship processor. Furthermore, it accelerates research and development for next-generation chips.
Rhea1, Europe's most complex processor, features 80 Arm Neoverse V1 cores. It contains over 61 billion transistors. SiPearl recently taped-out Rhea1, sending it to TSMC in Taiwan for manufacturing. This processor will power JUPITER, Europe's first exascale supercomputer.
Advancing European Chip Sovereignty
SiPearl strengthens Europe's technological sovereignty in supercomputing and AI. The company also fosters ties with Taiwan's semiconductor ecosystem. This strategic collaboration complements European chip independence.
The company, launched in 2020, now employs 200 people across France, Spain, and Italy. It has established sovereign infrastructure, including data centers for semiconductor design. This positions SiPearl to compete with global leaders like NVIDIA and AMD in high-performance computing.
The latest SiPearl Series A funding round prepares the company for its upcoming Series B launch. This investment also targets new market segments, including data centers, AI startups, and enterprises.
Rhea1 will equip the CPU cluster of JUPITER, owned by EuroHPC JU.
