Watch our partners describe our firm:


The world’s leading advisory firm on governance, joint ventures and transactions.

Water Street Partners advises clients on transactions and governance. Our transaction work specializes in joint ventures and other non-M&A partnerships, both in new deal formation and restructuring. On governance, we advise clients on corporate and joint venture governance, working with boards, management teams, and individual shareholders. We support clients around the world and across industries. 

Our work focuses on negotiating and structuring transactions, managing the launch and integration process, and supporting owners, Boards, and management teams on improving and, if needed, restructuring these businesses. We also work with companies managing portfolios of partnerships that are interested in deepening their capabilities in structuring and managing them.

We have built our firm around giving our clients access to the most experienced advisors, the most comprehensive database of practices and benchmarks, the best proprietary tools, and the widest network of practitioners in the world.

Based in Washington, D.C., our work spans industries and geographies. We are fortunate to have negotiated, restructured, or advised many of the largest and most complicated partnerships in the world. Since our founding in 2008, we have advised on 150+ JV transactions valued at $500 billion, and supported the shareholders, boards, or management teams in more than 300 existing joint ventures. Roughly 70% of our work is outside the U.S.
