Your slogan is: Stop boiling water. Why is that important?
Actually it’s Stop Global Boiling. It’s a play on words and I came to think of it as a wake-up call. When we say Stop Global Boiling, we mean two things at once: We must stop the overheating of our planet, and we must provide alternatives that can stop forcing people to burn fuel to make their water safe and hot. Our sun can help us do it and is for free. Energy is not only for power electric grids but is also a source for the most basic human need: clean, warm water at home. There are over 2 billion people without safe water that boils water over open fires — that’s the problem we are about solving.
How did the idea for this approach come about?
It’s was through observations of my mother Petra Wadström who is the inventor of the 10 litre Solvatten-kit and from her feelings for the women particularly in the global south that struggle in their daily life. She had a big frustration that not enough was done to solve their problems. Innovation is a creative process that takes a lot of decision making. It is now 800 000 people using the kits so its a proven solution solving problems every day
What were the main challenges during implementation? Was it more about the technical development itself, or about convincing people and organizations that it actually works?
The main challenge was never the families. Users trusted Solvatten immediately. They could feel the heat with their hands and see that it worked. Adoption was quick and natural. The harder part has been to convince the big international organisations that shape global development policy and their hinking.
Convincing the international organisations remains the toughest part.
David Wadström, Partnerships & Brand Director, Solvatten
There is a real big dissonance between how these institutions and their think tanks define the problem, and the solutions that households would like have. The women and households who owns the problem know exactly what they need: clean water and energy in their home. They judge a solution by whether it works in daily life. But the large multi lateral development institutions often prioritise systems, reports and long processes, which makes it difficult for simple, human centred solutions to break through. The Solvatten solution works and behaviors change. But convincing the international organisations remains the toughest part. That hesitation slowed things down far more than the technical development ever did.
The structure of Solvatten AB consists of a social and purpose-driven company in Sweden, a foundation in Sweden, and a foundation in the U.S. – how do these entities work together?
Solvatten is built as a mission-driven ecosystem and works through a mixed model. The company ensures strong technology and reliable delivery of impact from the projects we develop, including emission reductions (by Gold Standard and SBTI standards), while the foundations connect us to philanthropy, public funding and climate finance. By combining these streams we can move faster, reach more families and make sure that every Solvatten kit produces measurable health and climate results. It is a way to go beyond charity and create long-term value for people and for the planet. Philanthropic capital allows us to reach the places markets and governments do not reach. Each contribution accelerates access for the most vulnerable households and helps us bring safe hot water to communities that live entirely off-grid. Philanthropy is that bridge. The need is enormous, but so is the potential for change.
Revenue is a means to sustain the mission, not the mission itself.
What is a purpose-driven company?
A purpose-driven company is a business that exists to solve a real problem, not just to make a profit. It uses commercial tools, but its main goal is social and environmental impact. Revenue is a means to sustain the mission, not the mission itself. In our case the purpose is clear: to make safe, hot water available to the people who need it most and to reduce climate impact. Every decision, every partnership and every investment is guided by that purpose.
Do you also work with organizations in Switzerland?
We work with Gold Standard in Switzerland, one of the most trusted organisations for measuring real climate and health impact. Their rigorous certification helps ensure that every Solvatten kit delivers verified benefits for families and for the planet. We are also proud to partner with SFS Group AG, a Swiss-based precision engineering company headquartered in Heerbrugg, St. Gallen. Their expertise in high-quality fastening systems and global manufacturing reach adds real value.

What does this collaboration look like?
A good example is SFS Group support us in two ways. They provide high quality, optimised fasteners that strengthen the durability of the Solvatten kits, and they also make an annual financial contribution to help fund projects. Our first joint initiative is in Uganda, where the partnership now helps around 640 families in refugee settlements get access to clean hot water and reduce CO₂ emissions. It is a partnership we value highly.
SFS has many employees, and together we want to build a relationship that can grow and evolve over the years. SFS support Solvatten with both technical components and project funding, but just as important is the human side. We want their teams to feel connected to the impact. More stories from the field, more insight into how families use Solvatten every day, and more moments that make people proud of working for a company that commits to making the world better. It is engineering meeting empathy. And that is the kind of partnership we want to grow with SFS over many years. Solvatten is one of the few proven solutions that improves health, reduces emissions and saves families money at the same time. We invite philanthropists to join us in scaling a solution that works and counteract the warming effects of CO2 emissions on life on our planet.
