About us

You don’t want an ordinary job. You want to build something that truly matters. Be part of shaping it from day one, move fast and feel your impact. In a startup that doesn’t ask if something is possible – but how fast. Then you’ve come to the right place! 

At Bees & Bears, we’re a Climate FinTech on a mission to unlock capital for the energy transition. 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.
