Investment thesis
QDNL Participations invests in early-stage quantum technology startups, aiming to become the definitive global investor in quantum. The firm sees the current period as an optimal window for early-stage quantum investment as technologies and markets mature and non-dilutive capital becomes available. It bridges the gap between the grant-giving research phase and the patient-capital venture phase, providing hands-on business and commercial support to help technical founders build category-defining quantum companies across Europe and the US. The firm rejects a generalist or hands-off model, arguing the quantum space is too specialized and requires deep, active, quantum-specific expertise.
