The Global Family Office Report 2017 (GFOR) shows that more than a quarter of family offices (28%) report being engaged in impact investing, and two-fifths plan to increase their allocations in 2018. This investment method is now being practised across nearly every asset class, with 63% partaking in direct private investment, 57% in private equity funds, and 38% in venture capital. According to the GFOR, some family offices have trouble understanding how to source and implement impact investments. Environmental and social analytics providers can help by providing data-driven analysis for a practical measurement of impact. The rising influence of socially-conscious millennials in wealthy families means impact investing is only set to skyrocket. Family offices should get ready to be swept into the mainstream.
