Haas Impact Investing Network

Haas Impact Investing Network

The Haas Impact Investing Network (HIIN) provides MBA students with first-hand experience in impact investing. HIIN is part of a national network bringing together socially minded MBA students from top business engaged in the process of impact investing. This program is run by MBA Impact Investment Network and Training (MIINT) in partnership with Bridges Ventures, an impact investing firm led by Brian Trelstad, former Chief Investment Officer of the Acumen Fund.

MBA teams will go through the full impact investing process: conducting research on issue areas, sourcing potential social ventures, completing due diligence, and presenting an investment proposal on a company. At the end of the year, Bridges will invest $50,000 in one startup.
