What's your impact thesis — your theory of how you'll change the world for the better? A trusted advisor to makers and funders of change, Tamsin will help you define and measure the success of your impact thesis. Tamsin has partnered with 25+ foundations, high-net-worth individuals and families, nonprofit executives, and corporate teams on a wide variety of projects, including: philanthropic due diligence; monitoring, evaluation, and learning (MEL) capacity building; cost-effectiveness analysis; product strategy for impact measurement and management (IMM) solutions; theory of change workshops; and monetary impact valuation (impact accounting). As a methodologist, she created the blueprint for rating 2K+ charities on their cost-effectiveness at Charity Navigator (previously ImpactMatters) and developed global standards for valuing trillions of dollars in corporate social externalities at the International Foundation for Valuing Impacts. With experience at three nonprofit startups shaping the impact data ecosystem, she offers practical insight into overcoming the systemic barriers that keep changemakers and funders from finding and partnering with each other. Her work is grounded in hands-on experience with poverty alleviation programs in Haiti and cultural competence gained from living in Singapore, Australia, Taiwan, and the U.S. Send a message to Impact Thesis to learn more!
