About The Synergist

The Synergist is a social venture that addresses a growing need to collectively face societal issues by addressing broken or inefficient systems and accelerating societal (co-)impact. 

With globalization, the digital age, and increased mobility, we now collectively have more knowledge, capability, and capacity to solve the world’s most challenging social issues. But complex issues can’t be solved in isolation. The sheer number, variety, and interests of stakeholders on any given topic make it challenging to focus everyone’s expertise and resources on a shared goal. 

The Synergist is an independent, neutral backbone and incubator for societal issues. It brings together the right people, organizations, and institutions to focus on solving societal issues both personally and with technology tools. We foster an organized and collaborative environment that enables collective impact by co-defining a shared vision, goals, and strategies with members; bringing on board relevant partners; establishing and maintaining a transparent and balanced governance structure; coordinating and driving activities, and bringing to life concrete projects and solutions that have been shaped with and complemented by members.

The Synergist is a globally focused organization based in Brussels, Belgium.
