Tech Lead - Sustainable Finance AI Venture

Permanent employee, Full-time · Berlin

What we do

The climate transition demands radical changes in the way we do business, and trillions in new green capital investments. The EU has mobilized sustainable finance regulation to be a key means of driving this green capital into more sustainable business activities. 

Based out of the Berlin AI Campus and backed by Merantix AG, Briink is a team of entrepreneurs, lawyers, data scientists, and sustainability experts. Our mission is to leverage the scale of AI to help businesses and financial institutions make sustainable finance regulation actionable. This will speed up our journey toward a greener future. 

Our first product transforms the EU’s “green taxonomy” for sustainable business activities into a machine learning powered SaaS platform to enhance companies abilities to access green capital and accelerate their climate transitions.
