Zaiger Linden Roberti & Pepe LLC

What Zaiger Linden Roberti & Pepe LLC does

Zaiger Linden Roberti & Pepe LLC (ZLRP) is a privately-held national boutique litigation law firm operating from offices in Stamford, Connecticut; New York, New York; and Washington D.C. The firm was reconstituted in April 2025 from the prior Zaiger LLC (founded 2019) through the addition of co-founding partners Judd A. Linden, John Roberti, and Douglas J. Pepe alongside founder Jeffrey H. Zaiger, and now comprises approximately 13 professionals: four co-founding partners, two lateral partners, three counsel, one associate, and two paralegals. ZLRP represents corporate, institutional, and high-net-worth individual clients in high-stakes matters including complex commercial litigation, antitrust and competition law, class and mass actions, financial services litigation, legal malpractice and professional liability defense, insurance disputes, and representation of high-profile individuals. Its anchor client relationship is Black Diamond Capital Management, for which it has served as special litigation counsel since 2019, realizing hundreds of millions of dollars in recoveries while defending massive-liability cases.

The firm does not develop technology products; its core offering is professional legal services delivered by senior partners and counsel, with a notable specialized practice in blockchain and cryptocurrency law anchored by Douglas J. Pepe's patented cryptographic cold storage system. The firm's marketing emphasizes thought leadership through partner publications in Law360, ABA publications, Competition Policy International, and academic law reviews, alongside speaking engagements at Harvard Law, Fordham Competition Law Institute, and ABA Antitrust Section events. Revenue is generated through billable hours and alternative fee arrangements — including contingency, flat, and hybrid structures — with the firm explicitly positioning flexible fee alignment as a differentiator from traditional Big Law hourly billing.

ZLRP's go-to-market is enterprise field sales via partner-led client relationships, reputation, referrals, and content marketing rather than technology distribution channels. The firm competes on the basis of partner credentials (Chambers USA, Legal 500, Lawdragon 500, Benchmark Litigation, Super Lawyers recognitions across the partner roster), marquee case results, and a lean overhead structure that it markets as superior to large law firm alternatives for high-stakes matters.
