Longacre Square Partners, an advisory firm specializing in contested and special situations, corporate relations, and crisis management, has announced a strategic partnership with AI-Powered InvestorSight. This collaboration aims to further integrate analytics and insights into Longacre’s operations, expanding its advisory offerings for contested and special situations.
Under the terms of the agreement, Longacre’s client base will gain preferred access to new data and insights. These resources are designed to support a range of governance, financial, and mission-critical decisions. Longacre has also made an initial investment in InvestorSight, signaling a long-term, integrated partnership. Concurrently, Mark DesJardine, co-founder of InvestorSight, has joined Longacre’s advisory board.
InvestorSight employs advanced AI tools and models, developed from over a decade of scientific research, to deliver predictive intelligence and accuracy in critical decision-making processes. Its applications include proxy contests, hostile mergers and acquisitions, board refreshment, corporate governance, and shareholder litigation. Currently, InvestorSight’s models analyze more than 250 variables and can predict shareholder engagement outcomes with over 80% accuracy.
Dan Zacchei, a Managing Partner at Longacre, stated, “Greg and I believe that there is no partner in the AI space better positioned to help evolve the level of advice and breadth of services we provide our clients than InvestorSight. Mark and his colleagues have built something that uniquely sits at the intersection of contested situations, corporate governance and machine learning – making them an ideal complement to our areas of expertise. We look forward to working with InvestorSight to deepen the insights we offer clients and further integrate AI across our own firm.”
Mark DesJardine added, “It’s clear that Longacre’s subject matter expertise, commitment to investing in the next generation of technology and focus on client outcomes differentiates it from the pack. Our team is excited to collaborate on how we can build out the applications of our products for both boards of directors and investors, while continuing to add new verticals and offerings.”
Mr. DesJardine is the Paul E. Raether T’73 Faculty Fellow at Dartmouth College’s Tuck School of Business and a senior fellow at The Wharton School. He is recognized for his expertise in corporate governance and extensive publications on shareholder activism. His research involves utilizing large datasets and econometric tools to develop applied models that inform various aspects of shareholder engagements, including corporate vulnerability to activism and proxy vote outcomes. He serves as an associate editor at Management Science and a senior editor at Organization Science, and is also the Treasurer and a director on the board of the Alliance for Research on Corporate Sustainability and a CFA Charterholder.
