Hardt Hyperloop secures US-led funding for Americas push after bankruptcy

Rotterdam-based Hardt Hyperloop has secured a multimillion-euro investment led by US-based Green Rock, giving the transport technology developer fresh capital after bankruptcy proceedings at one of its entities and a partner for expansion across the Americas.

The round, reported by EU-Startups on November 4, also included existing investors and shareholders Perpetuum Ventures and Urban Impact Ventures. Its exact size was not disclosed. Alongside the investment, Hardt signed a strategic collaboration agreement with Green Rock to jointly develop hyperloop projects in North, Central and South America.

The agreement creates a transatlantic project-development partnership, rather than establishing a confirmed US operating footprint. The report identifies no American route, customer, office, construction schedule or deployment budget. For now, the US connection is an investor and development partner with ambitions across a much broader region.

Fresh capital after a financing crisis

The funding follows a period in which Hardt’s ability to continue depended on securing new money. According to EU-Startups, bankruptcy was declared in early March 2026, after an annual statement warned that survival was contingent on fresh capital and that available funds extended only through January.

The report describes the proceedings as involving one of Hardt’s entities but does not detail the legal structure of the recovery or the treatment of earlier liabilities. The new investment supports continued technology development, preparation for planned European hyperloop projects and the development of projects in additional markets.

“This investment marks a new chapter for Hardt Hyperloop after a challenging period, and enables us to continue with the development and deployment of our technologies,” co-founder Tim Houter said. He added that the collaboration with Green Rock opens up new hyperloop projects.

European engineering as the foundation

Founded in 2017 by a group of Delft University of Technology students, Hardt develops systems for fast, energy-efficient passenger and freight transport. Its engineering work includes magnetic levitation, propulsion and high-speed lane switching, with autonomous vehicles designed for speeds of up to 700 kilometres per hour. That design capability should not be read as an achieved operating speed.

Hardt’s European track record includes collaboration with Schiphol Airport on a hyperloop route plan and testing at the 420-metre European Hyperloop Centre in Veendam, the Netherlands. The facility has provided a setting to test and demonstrate core technologies; the source does not identify a commercial passenger or freight service.

The company also develops components including hybrid electromagnets, air-gap control sensors, silicon carbide-based magnet drivers and steel track sets. Its services extend to application engineering and route development, giving the Green Rock partnership a technical offering that spans components and project planning.

A development partner, not yet a US deployment

Green Rock describes its focus as strategic infrastructure and technology investment and project development. That combination matters for Hardt: the agreement links fresh financing with a partner intended to help turn its engineering work into projects outside Europe, while allowing European preparations to continue.

“We see real demand in the Americas for fast links between cities, and we want a technology partner that has built, tested and demonstrated the core technologies. Hardt is that partner,” Green Rock founder Cindy Huang said.

That demand assessment remains the investor’s view, rather than evidence of contracted routes. For Hardt’s American ambitions, the next meaningful milestones will be named projects, local counterparties and deployment plans. The financing provides a basis to pursue them, but the announcement does not yet establish where—or when—the technology will enter service.
