GLG (Gerson Lehrman Group)

Founded in 1998, GLG pioneered the expert-network model: giving professionals direct access to people with first-hand experience in specific industries, companies and markets. It is headquartered in New York and operates a global platform serving clients across financial services, private equity, consulting, life sciences, technology, corporations and law firms.

GLG matches clients with experts through direct calls, surveys, bespoke research, events, content and longer-term engagements. Its technology helps identify relevant specialists, while dedicated research and compliance teams screen experts, manage conflicts and structure compliant interactions.

The firm is especially strong in investment research and commercial due diligence, where clients need rapid perspective on markets, competitors, products or operating models. For early-career hires, the work can involve client solutions, research, expert recruitment, compliance, business development, events, or technology and analytics, often with exposure to senior investors, executives and technical specialists.
