What our investors say
Ralf Sonnenwald
Managing Director ES Kapital
Germany must take a pioneering role in hydrogen technologies and once again demonstrate its ability to innovate in order to remain competitive as a business location.
With our investment in water stuff & sun (WSS), we are supporting a start-up that brings enormous opportunities and disruptive potential to shape the energy transition. The immense versatility of the technology is impressive and we look forward to accompanying WSS in the further
development phases.“
The capital investment company of Kreissparkasse Esslingen-Nürtingen mbH, or “ES KAPITAL” for short, supports mediumsized companies in almost all development phases not only with individual equity solutions, but also with a holistic consulting approach and broad network.
Thomas Beyer und Curt Stoll
Managing Partners BESTO GmbH
As a family business, sustainability and resource conservation have been firmly anchored in our corporate philosophy for decades. For us, therefore, supporting new, climatefriendly technologies is a natural part of our cultural values.
After all, the climate crisis needs comprehensive decarbonization in various areas to ensure that our society remains fit for the future. We firmly believe that the hydrogen battery can make a decisive contribution to this.”
The “family office” of the two Swabian entrepreneurial families Beyer and Stoll – BESTO GmbH – has been successfully investing in highly innovative companies from a wide range of industries, including several technology startups, for many years. Behind the Beyer and Stoll families is, among others, the FESTO corporate group, the world’s leading supplier in the fields of control and automation technology with headquarters in Esslingen, which recently generated sales of around €3 billion.
Bernd Nagel
Managing Director NAGEL Maschinen- und Werkzeugfabrik GmbH
Innovation has been a top priority at NAGEL Maschinen- und Werkzeugfabrik for decades. And this is urgently needed, especially when it comes to energy storage technologies, because we all know: It is high time for a regenerative circular economy.
WSS combines two proven technologies in a unique way so that the problem of storage and application of renewables can be solved in a fundamentally simpler and more costeffective way than it has been done so far. This presents an opportunity to fundamentally change the way green energy is handled for the better – and for us, that’s true innovation.”
NAGEL Maschinen- und Werkzeugfabrik GmbH is the world’s leading specialist in the field of honing and superfinishing technology. In addition to the automotive industry, many other industries use this technology: from compressor and mechanical engineering to hydraulics and pneumatics and medical technology. The internationally operating company is active at 26 locations with over 1,800 employees.
Manfred Korn
Managing Director Comcotec Messtechnik GmbH und Business Angel
Fortunately, the expansion of renewable energies is now being widely discussed and promoted. And the question of how to store and distribute this energy is inherently connected to this – thus, safe and at the same time efficient transport and storage solutions are required to get the energy to where it is needed, namely directly to the consumer.
I’m excited to see the level of commitment and willingness to change in favor of an environmentally conscious lifestyle that the team at WSS is bringing to the development of a promising technology, and I’m very pleased to be a part of it through my investment.”
