Increasingly charities, social enterprises, companies and social investors such as funds and municipalities want to show and validate the impact of their work. It is crucial to know what works and what does not work.

Measuring impact plays an important role in this. We measure what matters. Involving stakeholders to understand what changes from their perspective is crucial. It ensures that organizations are accountable for the change that is caused by them, both intentionally and unintentionally.Sinzer offers tailor-made advice, always with goals that are both practical and ambitious.

The consistent measurement and reporting of impact enables organizations to:

  • make improvements that maximize impact

  • make better and informed decisions

  • attract new funding

  • Be accountability to stakeholders (such as financiers)

  • Communicate better about the change they are making
