Interest in impact investing is growing among high-net-worth individuals, particularly those who generated assets through entrepreneurship, according to this article in the Financial times.

"In a report last year, JP Morgan concluded that businesses aiming to deliver just five socially desirable goals - housing, rural water delivery, maternal health, primary education and financial services - for people earning under $3,000 annually, has the potential to attract anywhere from $400m to $1,000bn over the next 10 years. More than that, it offers potential profits of $183bn to $667bn.

"Andrew Haigh, managing partner at Coutts' Entrepreneurs Client Group, said that a number of its clients wanted to invest in precisely such channels. Many, he said, were entrepreneurs who may have recently become wealthy through the sale of a business and found themselves looking for places to invest not just cash but ideas and energy, as well. 'Early-stage investment is already on their radar screens,' Haigh says. 'Often, there is also a desire to give something back.'"
