Job Description

Summary
We are seeking an entrepreneurial leader to drive membership growth and strategic direction of the Joint Impact Model (JIM) Foundation. You'll lead a lean, globally distributed team to establish JIM as the preferred toolkit for economic, impact and climate risk management for investors and funders.
As Executive Director, you'll focus on four core areas: growing and retaining our membership base, developing go-to-market strategy, setting organizational direction in partnership with the Supervisory Board, and building a high-performance team. You'll work in close partnership with the Technical Director, who owns model development and technical excellence.
This role is a fractional leadership role (50-80% time) with potential to transition to full-time based on mutual success. While we cannot guarantee specific outcomes or timelines, we are exploring hybrid models that could create meaningful upside for entrepreneurial leaders who help us scale.
The Joint Impact Model Foundation
The Joint Impact Model Foundation is a non-profit organization that provides credible oversight for the development of the Joint Impact Model (JIM). The JIM enables its members (primarily financial institutions - including development finance and commercial finance actors) to estimate the impact of their investments by tracing financial flows through the economy. This analysis captures the resulting economic (value added), social (employment), and environmental (greenhouse gas emissions) impacts.
Launched by FMO and other international finance institutions in 2021, the foundation works towards harmonisation of key indicators to build accountability and steer financing in the US$140tn finance sector.
To further develop and grow the organization, JIM is now recruiting for an Executive Director.
