This month saw the inaugural Impact Investing Summit in Huntington Beach, Calif., hosted by IMN. The institutional investment conference drew lots of faces familiar to me, and was hailed for bringing some great people together.

In April, Pymwymic Impact days will be held in Amsterdam, featuring many social enterprises and funds with whom I am familiar.

Asia iix, the Asian Impact Investing Forum, will be hosted in Singapore this June. And it has grown to attract people from all over the world.

And, of course, the Impact Investing Workshop hosted by Financial Advisor and Private Wealth magazines will be held in July in Denver.

Sprouting from all these events are deals and, dare I say, friendships.

Just last week I had drinks with two attendees from our July workshop, one of whom received millions of dollars in investments from yet another friend and attendee.

What sews the fabric of any industry is a strong network of professionals. And impact investing has that in spades.

Indeed, networks are powerful, and smart people capitalize on them. They breed good ideas, relationships and business success.

In the face of social media, how can you not belong to a network?

Do you?
