Rhonexum Secures $1 Million Seed Funding to Tackle Quantum Computing Scaling Issues

Rhonexum, an EPFL spin-off, has raised $1 million in a pre-seed funding round led by QDNL Participations, with additional contributions from Venture Kick, FIT, SNF, and EPFL Startup Launchpad. The funding will accelerate product development, expand the design team, and deliver a control solution to customers within the year. Founded in November 2025 in Lausanne, Rhonexum aims to address a critical scaling obstacle in quantum computing by developing chips that operate directly in cryogenic environments while remaining compatible with standard CMOS manufacturing processes.
