What The Garrigan Lyman Group does

The Garrigan Lyman Group data block is mismatched to the bulk of the evidence, which describes GLG (legal name: Gerson Lehrman Group, Inc.), the world's largest expert network platform. GLG was founded in 1995 by Mark Gerson and Alexander Lehrman and is privately held, headquartered in New York, with 2,500+ employees across 13+ global offices spanning the Americas, EMEA, MENA, and APAC (including London, Singapore, Dubai, Mumbai, Tokyo, Seoul, Shanghai, Hong Kong, Sydney, Dublin, Austin, and San Francisco). The company connects decision-makers at financial institutions, private equity firms, consulting firms, law firms, and corporations with vetted subject-matter experts through its proprietary expert network.

GLG's product surface spans Expert Calls & Meetings, AI-Moderated Calls, Surveys, an Expert Content Library and Feed, Board Placements, and Deal Advisors. The myGLG platform serves as the central AI-powered hub, combining four AI-driven workflow tools — Ask (an agentic, conversational project builder), Match (expert matching), Gather (scheduling and AI moderation), and Synthesize (insight extraction from transcripts). The Bloomberg ASKB integration, announced in 2025, extends GLG's expert content into the Bloomberg Terminal's agentic AI interface. The company monetizes primarily through annual subscription contracts with quote-based pricing, supported by a sales-led enterprise GTM with dedicated account management and business development teams across global hubs, plus inside sales for mid-market and a self-service platform layer for existing clients. The company does not publicly disclose revenue or pricing specifics.
