Erwin Hieltjes

As a Principal Consultant in the Data and Learning team, Erwin leads on NPC’s evaluation and learning work with charities. He supports charities to maximise impact and improve learning with an eye for meaningful and proportionate evaluation. As an economist, he lets data analysis guide his decision making and ensures the right structures are in place for data-driven measuring, evaluation, and learning. Through theory of change workshops Erwin can help charities or funders develop their impact-driven thinking. He works on a wide range of topics, such as equal opportunities, gender equality, healthcare, sustainability, and social work.

Erwin has over 10 years of experience in the business and charity sector. He has a Master of Science degree in Economics from the Stockholm School of Economics and started his career as a Strategy Consultant at Booz & Company (now PwC Strategy&). He has since worked with several charities and funders, starting his own social sector impact consultancy in the Netherlands (Impacters) before joining NPC. Among others, he worked on programmes for disadvantaged youth (IMC Charitable Foundation), integration of migrants (Foundation New Home Rotterdam), at-risk single mothers (Mothers of Rotterdam) and the gender pay gap (Salaristijger). He is an experienced DE&I trainer with an expertise in unconscious biases.

Erwin is a trustee of the Healthcare Embassy, a foundation in the Netherlands aiming to unlock the potential of innovation in the healthcare sector.

Why I work at NPC

I use my background as an economist to support non-profits and funders in making better choices based on data-insights. Not just doing good, but doing best.
