Hades Mining, a deep-tech startup focused on unlocking ultra-deep geothermal energy and critical mineral deposits, has announced the successful close of a €5.5 million pre-seed funding round. The funding round was led by Project A, with Jack Wang at the helm, supported by Anton Waitz, Uwe Horstmann, and Jannic Meyer. Visionaries Tomorrow also participated, led by Thong Le Hoang, alongside Sebastian Pollok and Iris ten Have, PhD. Founders Factory and the Viessmann Generations Group joined the round, with participation from Jack Kennedy and Anna Stella Wahl (Fetha), respectively.
A distinguished group of angel investors added further support, including Florian Seibel, Moritz von der Linden, Roman Hölzl, Daniel Wiegand, Hélène Huby, Chris O’Connor, and Dr. Nicolas Burkardt. Existing backers, Interface Capital and FounderLake, also reaffirmed their support.
Founded by Dr. Max Werner, Björn Dressler, and Dan Gengenbach, Hades Mining is developing proprietary drilling and subsurface access systems designed to reach previously inaccessible depths. The company’s approach combines in-situ recovery (ISR)—a fluid-based mineral extraction technique—with ultra-deep geothermal access, enabling energy and resource production with minimal surface disruption.
With Europe importing over 90% of its critical minerals and more than half of its energy, Hades Mining positions itself as a strategic solution to growing geopolitical and environmental pressures. The company’s vertically integrated model—from licensing to production—aims to deliver scalable, sustainable access to the building blocks of modern society.
By accessing ultra-deep and stable heat reservoirs beneath the Earth’s crust, the company is unlocking geothermal energy at a new scale. This builds a foundation for energy abundance and global resilience.
And the company’s technology advances in-situ recovery (ISR), a low-impact technique that uses fluid circulation to extract minerals from deep rock formations without open-pit excavation.
This funding round sets the stage for Hades Mining to accelerate the development and deployment of its breakthrough technologies, reshaping how Europe powers its future.
