About us

We help innovators solve some of the world’s most pressing societal problems

Who we are

Everyday, across the world, innovation helps to solve problems and improve lives, but with some issues new ideas just aren’t being acted on fast enough.

We are challengers. 
We are innovators. 
We are game changers.

We understand the most pressing of these, shine a spotlight where it matters and incentivise people to solve them.

Our challenges pinpoint a problem and offer a prize for the first or best solution.

We are independent and inspire the best placed, most diverse group of people to find solutions; support the boldest and bravest ideas to become real, and seed long term change to advance society and build a better future.

Check out the steps to running an effective challenge prize in our new Practice Guide.

We are challengers and we are innovators, but we never work alone. We are part of the innovation foundation Nesta, and we work with governments, NGOs and businesses all over the world, as both advisory and delivery partners – helping them reach ideas far beyond their own boundaries.

Together we can be game changers.
