Set up in 2005, Prism has over a decade of experience administering the giving of high net-worth individuals, groups of donors and established foundations. 

We offer three unique services with the aim of streamlining and minimizing the administration around charitable giving.

Firstly, we provide Donor Advised Funds (DAFs) for high net worth individuals which act as an alternative to setting up your own grant making foundation. It’s simple; you tell us where you want to donate and we take care of the rest. We focus on a personal, flexible and swift operation ensuring any tax benefits are also utilised.

Secondly, we operate Collective Funds for groups who are starting their fundraising journey in the UK. Instead of the time and cost of setting up an operational charity, you can create an account at Prism.

Thirdly, we also provide Foundation Administration to other registered charities – both operational charities and grant making foundations – that benefit from outsourcing their board support and financial administration to save on time and costs. 

We are not strategists, we are administrators, and this helps our donors feel secure in the knowledge that we are experts in our field. We believe that the effective running of an operation’s infrastructure can significantly increase its impact, regardless of whether you are a high new worth donor, a fundraising group or a trustee.

Prism the Gift Fund's Impact

By combining the UN’s Sustainable Development Goals and the UK’s Charitable Purposes, Prism has formed nine main areas to help us measure our impact across the sector and around the world.

Starting from the beginning of our financial year, 2016/17, we will be categorising the work that we carry out. We want to know the impact that we have and what our clients have around the world. We are aiming to create yearly impact reports that will analyse how much Prism donates, and what cause the funds are being spent on.
