Water Street is a research and advisory firm devoted to improving the performance of joint ventures and alliances.

Water Street is the world's leading advisory firm on joint ventures and alliances. Our mission is to improve the performance of these businesses - assets that are central to their owners' strategies, but tend to introduce unique issues, challenges, and performance problems due to their shared ownership structure. 

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 are fortunate to have negotiated, restructured, or advised many of the largest and most complicated partnerships in the world. In the last five years, we have advised clients on more than 120 joint venture transactions with a total value of over $470 billion. Senior members of our team have personally advised on more than 600 ventures prior to founding or joining Water Street.
