About and Portfolio

I work with people and organizations to strengthen how they finance, measure, and improve their social impact.

Bio

At the University of Oxford, I lead the Impact Measurement Programme at Saïd Business School, enabling leaders to navigate the complexity of measuring and managing social impact, and teach in executive programmes on impact investing and innovative finance.

As a Senior Advisor at Impact Frontiers and IMM Lead at the Innovative Finance Initiative, I design knowledge initiatives and learning programs across multiple regions on fundamental frameworks, innovative models, and emerging practices for investors and practitioners.

As an independent advisor at Evalysis, I help organizations design strategies and structures for deploying impact investments and philanthropy, develop credible approaches to describe and evaluate social impact, and enhance organizational capabilities and learning.

My work is informed by two decades of global experience across sectors, regions, and organization types; board and advisory roles spanning nonprofit, investment, and field-building organizations; and a PhD from the University of Oxford.

Experienced in the work. Invested in the field.

I have worked at the intersection of impact measurement, impact investing, evaluation, and philanthropy for over two decades. The first decade was grounded in Canada — ranging from community economic development and social enterprise through to workforce development and the social finance sector in its formative phase. I co-founded Purpose Capital (now Rally Assets), which became Canada’s leading impact investment advisory firm, and contributed to the early stages of market-building through research, advisory, and national capacity initiatives.

The last decade has been more global — focused on consulting, teaching, and field-building across North America, Europe, Africa, GCC, and beyond. I grew up in Kenya, and have worked or presented in over 20 countries. Across this work, I have engaged with organizations across the capital spectrum: ventures, impact funds, impact investors, government agencies, and industry / sector networks across a variety of sectors. Today, this takes the form of a “portfolio career” that allows me to tap into global trends, regional models, and local innovations.

How I Work

Advisory, teaching, collaboration, and governance inform one another. I often work independently — as an advisor, evaluator, and researcher — but much of what I value most involves working with and through others: co-designing programmes, curating spaces for learning, and contributing to collective efforts.

Advisory

Impact Advisory

At Evalysis, I work with organizations, investors, and other actors seeking to strengthen how they finance, measure, and improve social impact. I typically engage when the work is innovative, complex, or contested — with the goal for impact claims to be credible, useful, and worth standing behind.

This often includes sharpening impact goals and strategies, strengthening measurement approaches and systems, building internal skills and capabilities, and supporting learning and knowledge. I push for rigour and impact integrity without losing sight of what is practical and useful.

Teaching

Executive Education & Practitioner Learning

Through Oxford and other settings, I teach impact measurement, impact investing, and related topics — and I design spaces where practitioners can come together to learn from each other, work through shared challenges, and build on what they know.

I lead the Oxford Impact Measurement Programme at the Saïd Business School, and teach on the Oxford Impact Investing Programme and Oxford Impact Finance Innovations Programme. I also design learning programmes for investors and practitioners through Impact Frontiers and the Innovative Finance Initiative.

Collaboration

Research & Field-Building

A significant part of the portfolio involves collaborative and field-facing work: contributing to frameworks, shared tools, practitioner initiatives, and newer efforts intended to strengthen how the field understands and approaches impact.

Currently I am a Senior Advisor to Rockefeller Philanthropy Advisors, developing new frameworks on systems thinking for impact investing, and I contribute to practitioner initiatives and field-level efforts through Impact Frontiers, the Innovative Finance Initiative, and field-building convenings.

Projects
Governance

Board & Field Governance

I have served in formal governance roles across different organizations. I’m currently on the Board (and Vice Chair) of CanadaHelps, Canada’s largest online charitable donations platform, and previously as an independent Non-Executive Director of the Arisaig Next Generation Fund (Article 9 ICAV) and on the Supervisory Board of the Impact-Linked Finance Fund Foundation.

I have also contributed to governance for field-building initiatives, including as Co-Chair of Ontario’s Impact Measurement Task Force, member of the G8 Impact Measurement Working Group, and co-founder of the Social Finance Topical Interest Group at the American Evaluation Association.
