Fast Company profiles Acumen Fund's Director of Business Development, Sasha Dichter, who talks honestly about the challenges facing impact investing today: finding the right talent, communicating the cause, and rigorously applying impact analysis and metrics.

There is no tradeoff,' he explains, the way there was a generation ago with the screened investment funds of the 1990s that peddled various 'vice-free' stocks. 'A certain amount of results have to be proven,' Dichter adds."
