Bridging capital with sustainable impact.
Sustenra helps corporations, philanthropies, and governments design and deliver programmes that last.
Who We Are
Sustenra is a women-led international development advisory firm that transforms funding into measurable progress.
We work across global health, governance, education, gender, and economic resilience. Helping organisations align their resources with credible, sustainable outcomes.
With decades of experience in global health and cross-sector collaboration, we strengthen systems and partnerships so that impact endures well beyond the first investment cycle.
What We Do…
Strategic Development & Philanthropy Advisory
We help corporations, philanthropies, and governments design strategic investments that align with ESG, CSR, and global development priorities to achieve measurable and sustainable outcomes.
Programme Sustainability & Continuity
We revitalise or transition programmes that risk losing momentum, embedding sustainability, local ownership, and resilience into their core design.
Systems Strengthening & Technical Support
Our team provides technical expertise to strengthen institutions, governance, and delivery systems across sectors including health, education, and policy.
Evidence, Learning & Impact Reporting
We build robust monitoring, evaluation, and learning frameworks that demonstrate accountability, credibility, and long-term impact.
Innovation & Resilience
We support partners to anticipate change, integrate innovation, and develop agile approaches that sustain progress in complex environments.
Partnerships & Capacity Development
We strengthen leadership, collaboration, and technical capacity to ensure organisations and local partners can deliver and sustain results independently.
