For years, Jean Case and her husband Steve have been invested in impact investing, but in the past twelve months, the CEO of the Case Foundation said at the Milken Global Institute Conference this week, acceleration has been huge. In addition to making a recent personal $50 million impact investing commitment, she joined dozens of other corporations, banks, foundations, and individuals including Prudential, the Omidyar Network, Capricorn Investment Group who collectively announced their commitment to invest nearly $2 billion in new dollars into companies and funds that are generating both positive financial and social returns. Case said that growth is in part because big finance companies like BlackRock and Bain Capital plan to move into the space as well. And while Case explains why mainstream investors have been slow to jump in off of the sidelines, she said that many are starting to jump now, realizing they can both make sound investments and have a positive impact. Case also told us why young tech entrepreneurs are now making huge contributions to impact investing.
