Problems we solve

Turning High-Stakes Questions Into Confident Decisions

The most important business decisions are rarely answered by publicly available information alone. When a private equity firm is deep in diligence on a complex acquisition, when a hedge fund needs to stress-test its thesis before market open, when a management consultant must understand a niche technology from someone who built it, when a law firm needs a credentialed expert witness with real-world standing, when a corporation is navigating a market entry and needs to know what the insiders know — that is when GLG delivers. We solve for the gap between what is widely known and what is actually true, closing it with verified, first-hand expertise from people who have lived and led inside the exact problem our clients are trying to solve. We address the challenge of access: connecting clients to the hardest-to-reach practitioners in the world, at the speed decisions demand. We address the challenge of trust: operating the most rigorous compliance and expert verification framework in the industry, so clients can act on what they hear. We address the challenge of scale: giving global teams the tools to run end-to-end research — from project brief to synthesized findings — without sacrificing the nuance that makes insight actionable. And we address the challenge of time: with 24/7 service coverage, AI-assisted research workflows, and a network of over one million experts, we help clients move faster than the competition without cutting corners.

Expert Calls

Expert Calls are GLG's foundational product and the most direct way to access the intelligence that lives exclusively in the minds of practitioners who have operated at the highest levels of their industries. A 1:1 Expert Call connects clients privately with a current or former executive, scientist, regulator, physician, engineer, or specialist whose specific background is precisely aligned to the question at hand. Calls can be used for industry deep dives, company insights from former employees, technical and specialist knowledge infusion, channel checks, and real-time monitoring of evolving market conditions. GLG's expert sourcing combines 25 years of proprietary network data with AI-powered matching and custom recruitment, meaning that even the most niche or hard-to-reach expert profiles can typically be sourced within hours. Our client-aligned service teams manage the full logistics of each engagement — from scoping and expert selection through scheduling and follow-up — so research teams can focus on the insight, not the coordination. Every Expert Call is conducted within GLG's compliance framework, with full transcription, speaker identification, and configurable data governance available through myGLG.

AI-Moderated Calls

GLG's AI-Moderated Calls bring the depth of a 1:1 expert interview to the scale of a quantitative research program. Rather than requiring a human moderator to be present for each session, GLG's AI Moderator conducts structured expert interviews autonomously — following a client-provided discussion guide, listening to responses in real time, and probing, clarifying, and following up dynamically based on what the expert says. The result is a research methodology that delivers the nuance and first-hand specificity of qualitative calls at the velocity and geographic reach of a survey program. AI-Moderated Calls eliminate the scheduling friction of coordinating human moderators across time zones, allowing clients to run parallel interviews simultaneously in multiple languages without sacrificing response quality. Every call is automatically transcribed with speaker identification and timestamping, and feeds directly into myGLG Synthesis — where AI surfaces themes, patterns, and key insights across the full set of transcripts with full traceability to original expert statements. Compliance teams can configure transcript holds, retention policies, and AI-generated summary replacements to align with firm-specific protocols.

Expert Content Library

The GLG Expert Content Library is one of the largest repositories of original, compliance-cleared expert intelligence available anywhere. Containing tens of thousands of named expert call transcripts, on-demand webcasts, and moderated interview recordings — updated daily — the Library gives research teams immediate access to first-hand perspectives on virtually any industry, company, regulatory environment, or market dynamic, without the lead time of scheduling a new call. Content is fully searchable, with AI-powered tools that surface key passages, generate instant summaries, and connect relevant excerpts to a research objective in seconds. The Library integrates natively with Bloomberg and FactSet, surfacing GLG expert transcripts directly alongside financial data and research tools in the workflows investment professionals already use. On Bloomberg, clients can use ASKB to query GLG Library content together with Bloomberg data, filings, and news in a single conversational interface. Within myGLG, Library transcripts can be pulled directly into research projects and processed through Synthesis alongside a client's own call recordings and third-party materials, creating a unified intelligence workspace for the full research lifecycle.

Our Expert Network

GLG's expert network of approximately 1.2 million professionals is the largest and most rigorously verified source of first-hand business intelligence in the world, with hundreds of new experts recruited every week. The network spans every major industry, function, geography, and seniority level — from Fortune 500 C-suite executives and former heads of state to clinical researchers, field engineers, regulatory specialists, and key opinion leaders operating at the frontier of their disciplines. What distinguishes GLG's network is not just its scale but its quality: every expert is named, verified against their stated credentials, and screened through GLG's proprietary compliance process before participating in any client engagement. When the right expert is not already in the network — and for the most specific or sensitive engagements, that is often the case — GLG's custom recruitment engine finds them. Our teams combine AI-powered profile matching with direct outreach to identify practitioners whose background addresses precisely the question at hand, typically within hours. The network includes more than 225,000 healthcare and life sciences professionals, more than 330,000 technology, media, and telecom specialists, and deep benches across financial services, energy, industrials, consumer goods, and the public sector — giving clients access to authoritative perspectives on virtually any market, anywhere in the world.
