He also chairs the Foundation’s Now Generation Network, bringing younger African perspectives into conversations about governance, leadership and the continent’s future.

That intergenerational instinct runs through much of his work: helping boards and leadership teams recognise the perspectives they are missing, think through moments of transition, and create the conditions for more informed decision-making.

Ways he can help:

• Strategic and governance counsel
• Leadership transition support
• Facilitated conversations at moments when an institution needs to reconsider what comes next

Through Synergos and his membership of the Next Generation Giving Pledge, he has worked across environments where funders, civil society, business and public leadership need to understand one another better if resources are to reach the places where they can have lasting value.

His interest is not simply in giving, but in the architecture around it: how families and organisations decide what they want their resources to do, how values become funding choices, how relationships are built across generations, and how funders understand the communities and contexts they enter.

Ways he can help:

• Identifying organisations and initiatives aligned with a family’s or institution’s purpose
• Connecting capital with local leadership, knowledge and networks
• Helping funders understand the cultural and institutional context in which they want to work

That experience gave him a practical understanding of what institutional ambition requires once it meets real conditions: systems, partnerships, operational discipline and the capacity to adapt without losing sight of purpose.

That experience now sits alongside his role on Sesame Workshop’s Global Advisory Board and his work with Africa CDC. In 2026, Africa CDC invited him to join the African High-Level Ministerial Committee on Global Health Architecture Reform as a Key African Strategic Voice. He has also participated in Africa CDC and WHO AFRO coordination around the response to the Bundibugyo Ebola outbreak in the Democratic Republic of the Congo and Uganda.

Across these roles, his focus is on the relationship between institutional ambition and practical delivery: how health and human development initiatives are shaped by local knowledge, how partnerships are built, and how programmes reach the people they are intended to serve.

Hosh’s work across human rights, civic space and culture includes current service with the Fund for Global Human Rights and Outright International, alongside earlier roles with the Sigrid Rausing Trust and The Africa Center. His support of the arts in the UK grounds his commitment to culture, human rights and the exchange between Africa and its diaspora.

Across these institutions runs a recurring concern: organisations working across countries and communities need more than good intentions. They need cultural knowledge, trusted relationships and enough contextual understanding to recognise what they do not yet know.

Maximising progress and joy through tolerance, respect, cultural diversity, exceptionalism and wisdom.

Ways he can help:

• Country and regional briefings
• Connecting institutions with trusted local expertise
• Advising on cultural and contextual entry into new geographies
• Reviewing programmes, partnerships and communications for local relevance
