But don't just take our word for it.

As climate risk becomes an increasingly important consideration, we chose to onboard the Unwritten platform to integrate climate risk assessment more systematically across our investment cycle. The platform enables us to conduct portfolio-specific and fund-level analysis independently, reducing reliance on external consultants and allowing for more timely insights.
