A decade ago, no one had heard of AirBnB, Uber, Spotify, Instagram or Snap. Or “impact investing.”

The term was coined, or at least adopted, at a 2007 gathering hosted by the Rockefeller Foundation at their Bellagio retreat center on Lake Como in the Italian alps. There was a follow-on Bellagio gathering in 2008 as well, so we’re straddling 2017 and 2018 for the 10-year anniversary.

But while those post-2007 sharing-economy and social-network startups have gone on to become proverbial “unicorns,” impact investing remains a largely boutique or marginal part of the worldwide financial markets, ever on the cusp of a tipping point.
