Gerson Lehrman Group is a private professional services firm founded in 1998 that operates an expert network connecting freelance subject-matter experts with institutional clients for primary research, advisory services, and consulting. The firm grew from a boutique matchmaking operation into a global platform with offices in major financial centers and presence across markets, industries, and policy domains. Its model intermediates expertise for Goldman Sachs, McKinsey & Company, Morgan Stanley, BlackRock and other investors, law firms, corporations, and non-governmental organizations.
GLG was founded in 1998 by Mark Gerson, Thomas Lehrman, and Alexander Saint-Amand amid rising demand for specialized industry intelligence during the late-1990s technology boom. Early work involved connecting investors active in Nasdaq-listed technology firms with former executives and analysts from Intel Corporation, Cisco Systems, and Microsoft. During the 2000s the firm expanded alongside growth in private equity and hedge funds, recruiting experts from Procter & Gamble, General Electric, Johnson & Johnson, and regulatory agencies such as the U.S. Securities and Exchange Commission. GLG opened offices in London, Hong Kong, and San Francisco while diversifying into healthcare by linking clients with clinicians from Mayo Clinic, Johns Hopkins Hospital, and biotech executives from Amgen and Genentech. The company scaled through the 2010s, competing with networks like AlphaSights and Third Bridge, and navigated scrutiny following regulatory investigations involving interactions between experts and clients during high-profile events such as the 2016 United States presidential election and the 2010s financial reforms.
GLG operates an expert network model that sources independent consultants, former executives, academics, and practitioners for paid consultations, advisory projects, and bespoke research. Typical engagements include one-on-one consultations, surveys, advisory boards, and on-site workshops involving experts from Harvard University, Stanford University, Yale University, and industry leaders from Pfizer, Boeing, ExxonMobil, and Toyota Motor Corporation. Clients—ranging from investment firms like Bridgewater Associates to legal practices such as Skadden, Arps, Slate, Meagher & Flom—pay fees per interaction or retainer fees for projects. The firm employs compliance protocols referencing standards from bodies like the U.S. Department of Justice and collaborates with law firms, corporate legal departments, and compliance teams at Citigroup and Barclays to mitigate material nonpublic information risks. Revenue streams include subscription services, hourly consulting fees, and long-term advisory arrangements with multinational corporations such as Siemens and Unilever.
GLG serves capital markets, management consulting, corporate strategy, legal discovery, and nonprofit clients across sectors including technology, healthcare, energy, consumer goods, and industrials. Institutional clients include asset managers like Vanguard Group, hedge funds such as Citadel LLC, and private equity firms including The Carlyle Group and KKR. Corporate strategy teams from Microsoft Corporation and Apple Inc. have used expert networks for competitive intelligence, while law firms engaged in litigation involving Merck & Co. or GlaxoSmithKline have retained experts for testimony and analysis. Nonprofit and policy clients have sought specialists affiliated with Brookings Institution, RAND Corporation, and Chatham House for advisory input on regulatory trends and geopolitical risk across regions including European Union, China, and India.
GLG’s corporate structure comprises a central management team overseeing global operations, compliance, recruitment, and client services, with regional offices led by country managers in hubs like New York City, London, and Hong Kong. Senior leadership has included executives drawn from firms such as McKinsey & Company, Goldman Sachs, and Accenture; board members and advisors have featured figures connected to Harvard Business School, Columbia Business School, and former government officials from U.S. Treasury Department and diplomatic posts. The company has pursued private equity investment and explored strategic partnerships with firms in Silicon Valley and Tokyo while maintaining private ownership and executive-led governance.
Expert networks, including GLG, have faced controversy over potential misuse of insider information, prompting investigations and settlements involving regulatory authorities like the U.S. Securities and Exchange Commission and scrutiny from members of United States Congress during probes into analyst conduct and information flows. High-profile cases have highlighted risks when experts with prior ties to corporations such as Enron or WorldCom provide sensitive commentary to hedge funds, leading to tightened compliance measures and litigation in civil courts. Media outlets including The Wall Street Journal, The New York Times, and Financial Times reported on instances where network calls overlapped with corporate earnings cycles or regulatory inquiries, spurring industry-wide reforms in disclosure and screening practices influenced by guidelines from Federal Bureau of Investigation investigations and corporate governance reforms.
GLG and associated executives have engaged in philanthropic activities, supporting educational and medical institutions including Harvard University, Yale School of Medicine, and Mount Sinai Health System, as well as arts organizations such as Museum of Modern Art and Lincoln Center. Corporate responsibility initiatives have emphasized pro bono consulting for nonprofits like Doctors Without Borders and Oxfam and partnerships with civic groups focused on workforce development and diversity, working alongside organizations such as Catalyst and United Way. Compliance and ethical frameworks align with standards promoted by industry associations and nonprofit policy centers including Transparency International and Center for Strategic and International Studies.
