What Halper Sadeh does
Halper Sadeh LLC is a New York-based investor rights law firm founded in 2015 by Zachary Halper and Daniel Sadeh, both Georgetown University Law Center graduates. The firm specializes in representing investors who have fallen victim to securities fraud and corporate misconduct, with a practice focused on securities class actions, shareholder derivative lawsuits, and investigations into the fairness of proposed M&A transactions and breaches of fiduciary duty by officers and directors. Notable matters include recoveries of $20 million in In re Galena Biopharma, $23.5 million in Thomas v. Magnachip Semiconductor, $24 million in Beck v. Walter Investment Management, and $7.25 million in In re Montage Technology Group. The firm operates on a contingency fee basis, advancing all costs and expenses and collecting typically 20-35% of settlement recoveries, with no upfront fees to clients.
The firm acquires clients through a low-cost, top-of-funnel distribution model that relies on press releases distributed via PR Newswire, GlobeNewswire, BusinessWire, and Financial Content, alongside a dedicated website (halpersadeh.com) that lists active cases, attorney profiles, and a free portfolio monitoring service. Its core service lines include shareholder rights legal representation, contingency-fee legal representation, M&A and transaction fairness investigations, derivative suit investigation services, and free portfolio monitoring to identify recoverable losses. The firm is privately held as an LLC, with no institutional investors, parent company, or disclosed funding, and operates from a single headquarters at One World Trade Center in New York with a headcount of 1-10 employees.
The firm's competitive positioning rests on the founders' combined credentials at prominent defense and securities class action firms, the federal judiciary, and the Office of the Attorney General for the District of Columbia, as well as a stated willingness to take cases to trial rather than settle early—a posture the firm claims enables higher recovery percentages for clients. The firm states it serves investors globally, accepts contact 24/7, and pursues its mission of maximizing recoveries, increasing corporate transparency, improving governance, and holding wrongdoers accountable. No AI/ML technology, proprietary platforms, or technology integrations are evidenced in the available data.
