As a Climate FinTech, we at Bees & Bears believe that capital is the key to accelerating the transition to clean energy.

The challenge we face is enormous: By 2050, €150 trillion must be invested worldwide to achieve climate neutrality. 65% of these investments need to be financed through loans.

Having recently secured a €500 million financing line, Bees & Bears is on a mission to inject this capital into the sustainable economy to accelerate the transformation and make the world greener.

We work closely with installers of green hardware such as energy storage systems, solar panels and heat pumps to enable their customers to pay a small monthly fee instead of investing tens of thousands of euros upfront.

Our software helps make financing as easy as buying a smartphone with a few clicks. This way, we massively accelerate the transition to renewable energy, strengthen the skilled trades sector and make green energy accessible to those who would otherwise be priced out by high upfront investment costs.
