Who I work with

Mission-driven organisations that have either hit a funder concentration problem or are proactive about avoiding one.

NGOs, think tanks, climate organisations and development bodies. Sector-agnostic and geography-agnostic, but internationally focused, with the strongest networks in Brussels and the EU institutions, Germany, London and the US.

What I do

  • Funder landscape navigationMapping the realistic field and triaging it, so effort goes where it can actually land.
  • Foundation diversification strategyMoving away from dominant funders into multiple, durable relationships.
  • Geographic expansionOpening new funding markets across the EU institutions, Germany, the UK and the US.
  • Fundraising operations and systemsCRM, donor mapping, pipeline and engagement tracking, stewardship protocols, AI-assisted proposal development.
  • Direct donor engagementRelationship cultivation with named funders, not outsourced list-building.
  • Proposal strength and win ratesSharpening institutional bids and the team habits behind them.

Why me

I started out working directly with refugees and displaced communities in fragile contexts, then spent a decade in institutional fundraising strategy, so I bridge frontline programme reality and funder language.

My Executive MBA, with a Business Mastery Project on ESG benchmarking in the NGO sector, added the private-capital side. Strategic and pragmatic: I execute, not just advise. I understand both public and private donors, and I work globally and remotely.

Engagement model

  • I

    Strategic Advisory

    Advisory input on strategy, funder selection and positioning, at an agreed cadence. Your team runs the work.

  • II

    Embedded Partner

    Working inside the team on the live pipeline: funder mapping, proposals, systems and stewardship.

  • III

    Full Engagement

    End to end ownership of the diversification effort, including direct donor relationships and bid leadership.

Levels differ by intensity and scope. Day rate is discussed directly and scoped to the engagement. Either way you get direct involvement in strategy, execution and relationship-building, not outsourced analysis.
