Trusts, foundations and other partners play a vital role in realising the potential of digital technology to improve lives.

We work with funders to build stronger tech for good programmes and connections - and support grantees with practical training in user-centred, digital service design.

We are open to hearing from any funders or partners interested in working together on long-term programmes or short-term consultancy projects: we can offer modular support on project management, ways of working, MEL (monitoring, evaluation and learning), user-centred research and design, co-production, service delivery - and more.

Please contact us at [email protected] and we will be in touch!

Funder +

Funder+ programmes combine funding with support for maximum impact. We work with grantees to embed digital in their organisational strategy, culture and services. We provide hands-on support and leverage our network of trusted partners to help nonprofits supercharge their progress within a funding period.

Find out more about our successful programmes with Deloitte and Sport England, as well as our Tech for Good work with Comic Relief and Paul Hamlyn Foundation.

GrantAdvisor UK

GrantAdvisor UK is a free platform designed to facilitate dialogue between grantseekers and grantmakers. Funders are invited to add their organisation to the GrantAdvisor UK site, in order to gather insights that will help refine their systems in line with applicants’ needs.

We communicate directly with funders to help them navigate the GrantAdvisor platform and make the most of the insights and feedback available. We also collaborate with organisations such as IVAR to synthesise key themes and needs - and ensure that the latest best practice advice is made available to funders.

AI for grantmakers - peer group

An opportunity for funders of all sizes to come together and explore the opportunities and challenges of AI. The group - which began meeting in December 2023 - now consists of more than 70 Trusts and Foundations, and is open to all UK funders, of any size. The next meeting will take place on 20th June (1pm-3pm) - to join this and / or future events throughout 2024, please contact [email protected]

Open IP and Reuse

Reuse is where one organisation uses a tool, service, process, asset or standard (or something else) developed by another organisation.  We’re particularly championing reuse of elements that are ethically produced and sector-owned. Where we can align reuse, we save money individually and collectively; speed up social innovation and can create better impact.

CAST works in collaboration with Catalyst on the Open IP and Reuse for Funders initiative, which supports funders to implement open IP standards within their work, and to encourage reuse amongst the charities they support. The initiative is open to all UK grantmakers, free of charge; please contact [email protected] to become involved.

One output from this ongoing work is a set of best practice guidance for grantmakers, comprising internal and external policies for Open IP, and best practice Terms and Conditions for grant agreements. These are open for all funders to access via this Google Drive Open IP and grantmaking guidance folder.


We provide a range of bespoke consultancy services which include modular support on project management, ways of working, MEL (monitoring, evaluation and learning), user-centred research and design, co-production, service delivery - and much more.

We also have extensive experience helping funders in assessing and supporting digital projects and applying digital technology to improve their assessment, monitoring and management of grants.

Testimonials from funders

CAST is a key agency operating in the ‘Tech for Good’ sector and has worked with Comic Relief in supporting not-for-profit organisations that we fund, enabling them to explore how to transform their services using digital technology. The CAST team are friendly, efficient, and responsive. They bring rich experience of building the digital capacity of hundreds of social enterprises, supporting them to embed digital and user-centred design into their strategy, culture, and services. Billy Dann, Head of Influence, Impact & Investment Directorate, Comic Relief

We worked with CAST to design a tool that would give applicants a more realistic understanding of what we would and would not fund. We were encouraged to build and test it with our users – doing this alongside applicants wasn’t always comfortable, and forced us to put ourselves in their shoes. So far we’ve cut applications by a third, meaning almost 1,000 organisations have saved time that would otherwise have been wasted.
