Cryogenic electronics startup Rhonexum, a Venture Kick alumnus, has secured USD 1 million in pre-seed investment, led by QDNL Participations. The round also includes support from Venture Kick and grant funding from Swiss innovation programs. The capital will accelerate product development and bring Rhonexum’s first industrial-grade cryogenic electronics product to early customers.
Rhonexum specializes in electronics capable of operating at cryogenic temperatures near absolute zero, a critical requirement for quantum computing. Conventional electronics fail under these extreme conditions, creating a significant bottleneck for scaling quantum systems. Rhonexum’s proprietary models and software enable electronics fabricated with standard semiconductor processes to function directly within cryogenic environments, overcoming a key obstacle in quantum technology development.
Founded in November 2025 as a spin-out from AQUA Lab at the École Polytechnique Fédérale de Lausanne, Rhonexum is led by Vicente Carbon and Dr. Hung-Chi Han. Dr. Han, an expert in cryogenic semiconductor physics and transistor modeling, previously worked at semiconductor giant TSMC. Vicente Carbon brings experience in robotics and systems engineering, focusing on translating deep-tech research into industrial applications.
In addition to QDNL Participations, Rhonexum has received early-stage support from Venture Kick, as well as non-dilutive funding from EPFL Startup Launchpad, Fondation pour l’Innovation Technologique (FIT), and the Swiss National Science Foundation (SNSF).
The newly secured funding will be directed toward expanding Rhonexum’s design team, accelerating product development, and delivering the company’s first cryogenic electronics solution to a select group of early customers later this year.
