Executive Director

We are seeking an entrepreneurial leader to drive membership growth and strategic direction of the Joint Impact Model (JIM) Foundation. You will lead a lean, globally distributed team to establish JIM as the preferred toolkit for economic, impact and climate risk management for investors and funders. The Executive Director role focuses on four core areas:

• growing and retaining our membership base
• developing a go‑to‑market strategy
• setting organizational direction in partnership with the Supervisory Board
• building a high‑performance team

You will work in close partnership with the Technical Director, who owns model development and technical excellence. This is a fractional leadership role (60‑80% time) with the potential to transition to full‑time based on mutual success.

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 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 toward harmonisation of key indicators to build accountability and steer financing in the US$140tn finance sector.

Key Responsibilities:

• Strategic Leadership and Operations: In partnership with the Supervisory Board, set organizational strategy and provide leadership vision. Develop annual business plans and budgets and maintain accountability for financial performance. Monitor developments in the impact and climate data sector to guide JIM's competitive positioning. Oversee day‑to‑day operations to ensure delivery against strategic goals.
• Membership Growth & Retention: Build, grow, and retain a vibrant membership base of financial institutions, ensuring high satisfaction, strong retention, and measurable improvements in their impact management capabilities. Develop and execute go‑to‑market strategies targeting DFIs, impact investors, commercial banks, and other key segments. Lead member engagement, ensuring responsive support and continuous feedback loops that drive product improvement.
• Fundraising & External Representation: Serve as primary external spokesperson at industry events, stakeholder gatherings, and member forums. Lead fundraising efforts with DFIs, donors, and standard‑setting bodies to diversify revenue and ensure JIM's global alignment and interoperability.
• Team Leadership & Culture: Build a mission‑driven, transparent culture suited to a lean, globally distributed team. Provide coaching and mentorship to staff, particularly commercial and membership teams. Ensure the technical team (led by the Technical Director) has adequate resources and is strategically aligned with business objectives.
• Product Strategy & Prioritisation: In collaboration with the Technical Director, set product roadmap priorities that balance member needs, commercial opportunities, and technical feasibility. Ensure alignment between technical and business objectives.

Requirements:

• Essential: 10+ years of professional experience, with 3+ years in leadership roles. Proven success in membership‑driven, subscription‑based, or platform business models (SaaS, data products, impact measurement tools, or similar). Experience engaging with development finance institutions, impact investors, or organizations focused on emerging and developing economies. Demonstrated P&L accountability, budget oversight, and financial reporting to boards. Proven go‑to‑market success: sales, business development, and/or institutional fundraising in B2B contexts. Strong stakeholder and membership management skills, with ability to build partnerships across commercial, impact, and technical communities. Experience building and leading cross‑functional teams, particularly in distributed or remote settings. Comfortable understanding and discussing technical concepts (e.g. economic modelling, data architecture, software development) – conceptual fluency essential, hands‑on technical execution not required. Entrepreneurial mindset with comfort navigating ambiguity in lean, fast‑paced environments. Fluent in English; additional languages advantageous. Willingness to travel approximately six times per year.
• Desirable: Knowledge of ESG, sustainability, and/or climate data products.

Benefits:

• Fractional contract role (60‑80% FTE) for the first 12 months with annual compensation equivalent to €143,000‑€192,000 FTE; clear pathway to full‑time employment based on mutual success.
• A chance to lead and shape a pioneering organisation in the field of impact measurement and sustainable finance.
• A dynamic, international team, passionate about impact and innovation, supported by an engaged membership network of leading financial institutions.
