What GLG does
GLG (Gerson Lehrman Group, Inc.), founded in 1998 and headquartered in New York, is the world's leading expert network platform. The company connects enterprise clients with a curated network of approximately 1.2 million vetted experts spanning 230+ countries and regions, enabling access to authoritative human expertise for due diligence, investment research, market analysis, and strategic decision-making. GLG's primary customers include major financial institutions (serving 9 of the top 10 global banks), 1,000+ private equity firms, leading management consulting firms, major law firms, large pharmaceutical companies, and large technology companies. The company is privately held, has raised approximately $442 million in private equity across three rounds (Bessemer 2004, Silver Lake 2008, SFW Capital 2015), and currently employs between 1,001 and 5,000 people across 17+ offices globally.
GLG operates a platform-plus-modules architecture. The core asset is the Expert Network, which powers multiple service lines: Expert Calls & Meetings (1-on-1, AI-Moderated, translated, and multi-party engagements), Research (Surveys, Qualitative Research, Strategic Projects), Expert Content (Library and Feed, adding 600+ transcripts and event replays monthly), Events (300+ monthly roundtables, conferences, webcasts, and site tours), and Advisory & Placements (Board Placements, Deal Advisors, Talent on Demand). The recently reimagined myGLG client platform layers AI capabilities onto this network, including Ask (agentic project-building), Match (behavioral-data-driven expert matching), Gather (AI-moderated or live calls), and Synthesize (AI transcript analysis that can compress 10 expert calls into minutes). Underlying proprietary technology includes conversational agentic interfaces, NLP-powered synthesis, real-time speech-to-text moderation, and a content library augmented by AI-generated Q&A. Distribution combines direct enterprise field sales with dedicated 24/7 client teams, the self-serve myGLG portal, and channel integrations with Bloomberg Terminal (ASKB) and FactSet.
Revenue is generated primarily through professional services engagements (expert calls, research projects, advisory placements) priced per consultation based on scope, duration, and expert seniority, complemented by recurring subscription access to the Expert Content Library. Contracts are predominantly multi-year enterprise agreements with no publicly disclosed pricing. Go-to-market is sales-led with enterprise field teams aligned to client workflows across all major geographies. The company's market context is the ~$3 billion expert network industry in which GLG is the dominant player; the firm has continued to expand geographically (new San Francisco office March 2026), broaden its product surface (reimagined myGLG, Bloomberg ASKB integration), and publish original research on emerging enterprise themes such as agentic AI adoption.
