We believe finance is the key to accelerating the shift toward a sustainable future. The challenge ahead is massive: by 2050, the world needs to invest €150 trillion () to reach climate neutrality. 65% of this investment will need to be financed through loans.Our mission is to channel capital into the sustainable economy — to accelerate the transition and make the world greener.What we do:We work closely with installers of climate hardware such as solar systems, energy storage, and heat pumps — enabling their customers to finance installations easily through monthly installments. Our platform provides the technical and financial foundation to make this happen. In doing so, we're actively accelerating the energy transition — for households, for our partners, and for the planet.We've recently secured €500 million in funding commitments to green 25,000 households over the next two years. Prior to that, we raised two funding rounds backed by several renowned VCs — and we've been growing rapidly ever since.
