When philanthropists give, says Halton, they need to give well. That’s why Philanthropy in Action’s ‘particular specialism’ is incubating new models for ‘the giving of time and the giving of money’. Philanthropy isn’t easy: ‘I think people get frustrated because very often they want to give, and they give money in a very generous, but slightly scattergun way.’ Donors need the right tools, as well as the contacts and philosophies, to create positive change. This led to her setting up Social Venture Partners, where a group of HNWs gets together to talk about how to give effectively and to investigate the causes they’ll support on their ‘philanthropic journey’; they then learn how to check that their money is reaping its intended crop. It creates ‘maximum knowledge’ for time-poor but generous Londoners.
