About the Deal

Founded in 2019, SiPearl specialises in the development of energy-efficient high-performance computing (HPC) microprocessors. The firm has successfully raised €90 million in this first round of its Series A funding. Participants in the funding round included semiconductor design and silicon IP firm Arm and data and security specialist Atos Group through its Eviden business. The European Innovation Council (EIC) Fund and French Tech Souveraineté also contributed to the funding, which included up to €25 million of convertible debt from the European Investment Bank (EIB).

Rhea’s energy-efficient data processing power is designed to address obstacles in research, security, energy management and many other fields. Funds will also be used to expand SiPearl’s R&D and production capabilities while scaling up its commercial operations, with more investors expected to join the funding round in 2023.
