At Challenge Works, we design and run challenge prizes to spark innovation in science, technology and society. Challenge prizes offer a series of incentives in return for solving a defined challenge – creating breakthrough innovations, helping innovators thrive and unlocking systemic change. Since 2012, we’ve run over 100 prizes, awarding more than £250m to global innovators. We partner with governments, philanthropists and businesses to deliver high-impact competitions focused on frontier tech, climate, cities, health and international development. As innovation experts, we combine research, lived experience and sector insights to create real-world change. Challenge Works is part of Nesta, the UK’s innovation agency for social good.
