GLG

Investment teams at family offices frequently need expert perspective on private companies, industries, or regulatory environments that no public database can provide. GLG, founded in 1998 as Gerson Lehrman Group, built the expert network category and connects clients to a pool of approximately 1.2 million professionals spanning every industry, geography, and seniority level. For investment professionals conducting pre-deal diligence, sector analysis, or portfolio company assessments, GLG offers structured access to former executives, operators, and subject-matter specialists who can speak to first-hand experience rather than aggregated data.

Private equity firms are explicitly listed among GLG’s primary client segments, and the platform’s case studies include deal team support for PE clients evaluating niche assets and competitive landscapes. Family office investment teams conducting similar work would engage GLG through several distinct formats:

• GLG Calls: one-on-one or multiparty conversations with individual experts on a specific topic
• GLG Surveys: quantitative research fielded to targeted B2B expert respondents
• GLG Integrated Insights: managed projects combining expert interviews, market assessments, and competitive analysis
• GLG Qualitative: moderated focus groups and discussion panels
• GLG Library: subscription access to event transcripts and research replays

The myGLG client portal allows users to search the network directly, launch projects, and synthesize findings across past transcripts. GLG also maintains an industry-leading compliance framework with a dedicated global team that manages conflicts of interest and restricts the sharing of confidential information, which matters to investment teams concerned about material non-public information exposure. Pricing is not publicly disclosed, which is typical for engagement-based expert network models. Teams that need ad hoc access rather than ongoing subscription volume may find the cost structure less suited to occasional use.
