Who’s Involved
The Flush Forward Challenge is delivered by Challenge Works, in partnership with Bluechain Consulting and Cranfield University and is funded by the Gates Foundation.

At Challenge Works, we design and run challenge prizes to spark innovation in science, technology and society. We are part of Nesta, the research and innovation foundation. Our challenge prizes offer a series of incentives in return for solving a defined challenge, creating breakthrough innovations, helping innovators thrive, and unlocking systemic change. We are innovation experts, embedded in science, technology and entrepreneurship. We are problem-centred, drawing on insights from lived experience and sector experts to create positive change. We are thought leaders in using innovation to drive impact. We have run over 100 challenge prizes awarding over £370m on behalf of public, private and philanthropic funders around the world.
