What Longacre Square Partners does

Longacre Square Partners is a private, full-service communications and special situations advisory firm founded in 2022 and headquartered in New York, with additional offices in Tampa, Dallas, Washington D.C., Toronto, and London. The firm serves corporate boards, management teams, founders, and institutional investors on high-stakes matters spanning five interconnected practice areas: Corporate Positioning and Investor Relations, Corporate Governance and Shareholder Activism, M&A and Transactions, Crisis and Special Situations, and Financial Institutions and Investment Funds Advisory. Longacre Square is differentiated by a senior-led, high-touch model where approximately 40 practitioners work directly with clients on transformative events, transactions, capital raises, crises, and contested situations.

The firm operates a professional services revenue model, with fees structured as bespoke advisory engagements that are quote-based and not publicly disclosed. There are no products, software, or platforms sold; revenue derives entirely from senior practitioner time on client mandates. The firm has been ranked #1 Overall Global IR/PR Advisor on Bloomberg's Global Activism League Tables for four consecutive years, with 129 contested matters handled in 2024 and more than 100 representations in 2025. Notable clients span issuers and investors across sectors including healthcare (CVS Health, Steward Healthcare), media (Disney), technology (Figure AI, Vizgen), financial services (AmeriServ Financial, MoneyGram, GoldenTree), and apparel (Gildan Activewear).

Founders Greg Marose and Dan Zacchei lead a partnership that has been built through aggressive lateral hiring from premier institutions — BlackRock Investment Stewardship, ISS, Sloane & Company, FGS Global, DGA Global, Kirkland & Ellis, Brunswick Group, and Edelman. The firm does not have external institutional backing or parent company ownership and is privately held by its founding and senior partners. In October 2025, Longacre Square entered a strategic partnership with AI startup InvestorSight to embed investor behavior analytics and modeling capabilities into its client work.
