Initial assessment recorded
Assessment reviewed 6 Sept 2026
Formerly QDNL Participations. Renamed Ground State Ventures in April 2026; this is the same organization, not a second entry.
What it does. Where it fits.
Specialist venture funding and company-building support
Who should look closer
Early quantum founders seeking a specialist first investor, and readers following the emerging component and infrastructure companies behind the larger hardware platforms.
QubitWire’s editorial assessment of practical fit.Explore the firm and portfolio
The official site describes its investment focus and supplies a contact route for founders. Funding follows investor selection and is not an open-access service.
Check the current access route ↗What has been demonstrated
Rhonexum confirms that QDNL Participations led the equity investment within its $1 million pre-seed financing announced in March 2026. The investor's April announcement confirms the Ground State Ventures rebrand and says its fund had reached $88 million while approaching final close.
What remains unresolved
The cited April update does not confirm a completed final fund close. A funded company or announced portfolio valuation does not establish realized investment returns or delivered technical performance.
The next question to watch
Can new portfolio companies document delivered products and customer adoption, and is a completed final fund close subsequently confirmed by the firm?
A research question, not a promised milestone.QubitWire coverage
