About us

Our Mission

Our mission is to make social impact measurement accessible and cost-efficient through our software solutions and services, in order to enable organizations to manage and report about their impact consistently and maximize their value.

Why measure impact?

An increasing amount of social purpose organizations (NGO’s, non-profits, charities and social enterprises), funders/investors (both public as private) and multinationals are united by a common goal: creating social, including environmental, value.

In order to reach that goal and further amplify it, it is crucial to know which approaches work best and why. This is where social impact measurement comes into play.

Measuring and managing social impact helps you involve your stakeholders, understand what changes and value what matters. Impact measurement furthermore enables you to be accountable for the changes created by your organization. Lastly, measuring impact will provide you with insights into where and for whom you are creating impact and how you can maximize this.

How we can help you

We support social investors and mission driven organisations in measuring, managing and maximizing their impact.

Our team of impact consultants and software developers enables us to offer:

  • Consultancy, training and support services for impact measurement
  • Impact management software with a selection of standardized frameworks and metrics or customized to your specific needs

Kellie Liket

Researcher Erasmus University Rotterdam

Dr. Kellie Liket completed a PhD at the Erasmus School of Economics, Rotterdam, with a focus on the role of impact evaluations in strategic decision making. Her work has been published in various academic journals, including the American Journal of Evaluation. With her work she aims to advance the ability of corporations, governments, financial institutions and philanthropic organizations to use the results from impact evaluations to perform analyses that allow them to maximize their impact.


It all started at the fireplace in the office of Paul Baan. After his successful career at The Baan Corporation and their IPO he founded Noaber Foundation, in which he invest (parts of) his capital with the aim to create social impact. This was a new investment approach at that time, where philanthropy meets venture capital techniques. This new paradigm needed an approach to measure social impact in order to manage investments effectively and report about the performance. The concept of Blended Value and Social Return on Investment, founded by Jed Emerson, fitted this need. After consultation with other family offices, Noaber foundation (under the direction of Pieter Oostlander), d.o.b foundation (under the direction of Tera Terpstra) and Peter Scholten (a Dutch SROI expert) decided to develop an online tool for impact measurement: Social E-valuator.

Social E-valuator was launched in 2008 and started off as a solution for foundations across Europe. It did not take long however, before Social E-valuator started offering training, consultancy and other services to embed impact measurement for a broad variety of organisations around the globe.

In 2012 our main asset, software, was ready for an update after four years of maintenance of the first version. After a business reset under new management and investors we teamed up with a software development team in India and together we built a brand new software platform for measuring impact: Sinzer. Late 2014 we launched Sinzer with VSB foundation, Cordaid Investments, ABN Amro and Ecorys as launching customers.
