At CAST we know that technology can revolutionise how we address social problems.

So we developed Fuse. The world's only nonprofit technology accelerator. Fuse works with established nonprofits to build scalable, user-centred, digital services.

Thanks to the support of Big Lottery Fund, we're expanding the reach of Fuse and are looking to recruit six nonprofit partners in 2017 and six more in 2018.

Applications for 2017 are now closed, but do sign up to our newsletter (at the bottom of this page) for updates on our next intake.

How it works


Digital Team

We wrap an expert digital team around the nonprofit staff who join the Fuse programme


Tested Service

Over a 3 month period we prototype, test and develop a digital product or service that supports the social mission of the nonprofit



At the end of the 3 months, there's not just a tested digital product, but a roadmap for its future development



Fuse avoids silos - throughout the 3 month development process, other teams from the nonprofit are integrated into the product and service development to support its growth



Nonprofit staff participating in Fuse gain hands-on training in digital product development and a strong digital network. This means they're skilled and empowered to continue the work
