Grayslake Advisors

What Grayslake Advisors does

Grayslake Advisors LLC is a private business consulting firm founded in 2010 that provides expert witness testimony and litigation support services in economics, finance, accounting, and real estate. The firm operates from offices in Los Angeles (headquarters) and New York City with approximately 10 professionals on staff. Its clients are concentrated in large multinational law firms including Kirkland & Ellis, Quinn Emanuel, Skadden, and Latham & Watkins, alongside Fortune 500 corporations such as Goldman Sachs, and federal agencies including the SEC, FBI, and U.S. Attorney's Office.

The firm's service offering spans five practice areas: forensic accounting, damages assessment, real estate litigation support, securities litigation, and valuation and financial analysis. Principal and Founder Paul Habibi anchors the practice through a UCLA faculty appointment and a personal track record of more than 250 expert witness engagements. The bench is supported by PhD-level economists, CFA charterholders, and affiliated experts such as Joshua Stein, a prominent commercial real estate legal authority. The model depends on credentialed human expertise and academic credibility rather than proprietary technology platforms, with no disclosed AI or software product.

Grayslake generates revenue on a fee-for-service professional consulting basis, billing by engagement or billable hours at rates typical of senior expert witnesses in complex commercial litigation. The go-to-market relies on outside-counsel referrals, the founder's professional and academic network, and government contracting channels unlocked by federal contractor status. With roughly ten professionals and no disclosed revenue figures, the firm operates as a niche boutique competing against larger litigation consultancies such as Cornerstone Research and Berkeley Research Group.
