SeaChange “makes markets” by carefully connecting parties within our network – one to one or in group convenings – when we see that they have complementary goals.


We convene groups around topics of common interest that seem likely to lead to transactions. These convenings have included nonprofit mergers and collaboration (Boston, 2009), Social Impact Bonds (New York, 2010), Charter School Consolidation (Washington, 2010), funding mergers and collaboration (Los Angeles, 2014), high-impact credit (2015) and risk management (2016).


Board Leader Roundtables

SeaChange regularly convenes roundtable lunches for board leaders in New York City to address specific and timely issues critical to New York City nonprofit board governance. Topics have included nonprofit M&A, HHS Accelerator, changes related to the change in Mayoral administration, the bankruptcy of FEGS, a conversation with the Chief of the Charities Bureau, the movement to value-based payments, etc.


Greater NY Cross-Sector Partnerships

Greater NY was founded in 2008 by Cheryl Cohen Effron and Jamie S. Rubin as a private sector response to the financial crisis. From 2009-2014 GreaterNY operated as a public-private venture of the Mayor’s Fund to Advance New York City. Since 2015 Greater NY has been an independent nonprofit housed at SeaChange. Through Greater NY, senior corporate executives and law partners have the opportunity to be matched with a nonprofit CEO for a unique high-impact engagement to address critical nonprofit business issues including growth, restructuring, talent, brand, core capacities, board transformation, and social enterprise.
