Who we are

WTT is a non-profit foundation created to connect innovators and technology developers with opportunities for social, environmental and economic impact.

What we do

We create room for the experimentation of technological, social and business-model innovations in communities and contexts where they can have a positive impact. We accelerate the development of a new generation of technologies designed to solve critical social and environmental challenges.


How to connect innovative solutions to the most critical social challenges?

We connect communities and local NGOs to innovators, creating room for experimenting with technological, social or business-model innovations in the field. In this process we instigate innovators to consider the social and environmental potential of their solutions, and create opportunities for deploying them in real-world contexts where they can have a positive impact.


How to support impact inventors and innovators to cross the "innovation valley of death" and take their solutions to market?

WTT identifies and supports innovative technologies with the potential to promote large-scale impact. We provide a wide range of support, including funding, strategic planning, project management and networking. WTT helps entrepreneurs and inventors cross the "innovation valley of death", whilst directing their efforts towards the development of products or services aimed at solving the great social and environmental challenges of the 21st century.


How to foster a culture of innovation in low-income communities?

Community Innovation Centers are places where community members can access the tools and support they need to develop technological solutions or new business models that allow them to overcome their own challenges.
