Nexus Expert Research vs GLG: Which Expert Network Fits Your Brief?

GLG is the default choice for large institutional buyers who need a multi-format research platform with broad coverage across nearly every industry. Nexus Expert Research is the better fit for teams running niche or technical due diligence who need experts custom-recruited for their specific brief, not matched from a 25-year-old membership pool.

The core tradeoff is straightforward: GLG offers scale and breadth; Nexus offers sourcing precision and niche depth. Which one is right depends entirely on what your brief requires and how your team buys research.

If your engagement needs a specialist that a generalist database is unlikely to surface, such as a Big 4 director with sector-specific transaction history, a former regulator in a narrow jurisdiction, or a technical lead with operational experience in a hard-to-reach vertical, Nexus is built for that brief. If you need multi-format research at high volume with an established institutional platform, GLG is the category standard.

How Nexus and GLG Source Experts Differently

The sourcing model is the most consequential difference between these two firms. It shapes expert quality, shortlist relevance, and how well the network performs under a difficult brief.

GLG’s Approach: Matching from a Standing Database

GLG operates a pre-built membership network of approximately 1.2 million professionals who have opted in to the platform over more than two decades. When a client submits a brief, GLG’s team, now assisted by agentic AI tools introduced in the May 2026 myGLG relaunch, searches that existing pool and surfaces relevant profiles.

For topics with dense database coverage, this model is fast and efficient. The problem is structural: the same senior profiles get recycled across many client engagements. A frequently-called industry expert may have spoken with dozens of funds on similar topics, which creates both a relevance problem and, in sensitive diligence contexts, a confidentiality risk.

For niche, technical, or emerging-market briefs, the database depth thins noticeably. GLG’s network was built over 25 years through passive opt-in, which means coverage skews toward well-represented industries and seniority levels rather than hard-to-find specialists.

Nexus’s Approach: Recruiting from Scratch

Nexus recruits every expert from scratch against each specific brief. There is no standing membership pool. When a brief comes in, the team actively identifies, vets, and recruits the right individual for that engagement.

This matters most when the brief requires profiles that a standing database is structurally unlikely to surface:

• A Big 4 director with sector-specific transaction history in a narrow vertical
• A former regulator with jurisdiction-specific enforcement experience
• A technical lead with direct operational experience in an emerging technology category
• A senior operator from a geography where passive opt-in networks have thin coverage

Custom recruiting takes more time upfront than database matching. The payoff is a shortlist where every entry is genuinely relevant to the brief, not a best-available match from a pool built for different purposes.

The Tradeoff

GLG is faster for broad, well-covered topics where the database has depth and speed matters more than precision.

Nexus is more precise for narrow, specialist, or sensitive briefs where recycled profiles create relevance risk or where the right expert simply is not in any standing network.

Pricing and Commercial Structure

Pricing is one of the most common reasons teams evaluate alternatives to GLG. Both firms keep rates off their public websites, but third-party benchmarks give a reliable picture of what clients actually pay.

GLG Pricing

GLG does not publish rates. Independent benchmarks from expert network comparison sources put effective per-call rates between $1,000 and $2,500 per hour once credit multipliers and platform fees are included. The range reflects seniority, topic, and account structure, but even the lower end is a significant cost per engagement.

Most clients are onboarded via annual retainers or pre-purchased credit packs, often in the tens to hundreds of thousands of dollars. Credits expire if unused, creating a “use it or lose it” dynamic that penalizes teams with variable or project-specific research volumes. For a hedge fund running continuous thematic research, this structure is workable. For a PE deal team running diligence on a single transaction, it is often oversized.

GLG’s content library (20,000+ transcripts as of late 2023, with around 500 new items per month) partially offsets the per-call cost for teams that can reuse existing research, but the underlying commitment structure remains the same.

Nexus Pricing

Nexus operates on a per-project model. Expert calls are priced between $700 and $1,000 per hour, billed per engagement. There is no minimum annual commitment and no credit block that expires at year-end.

The practical difference: teams with variable research volumes, those running one or two expert engagements per quarter rather than dozens per month, pay only for what they use. There is no overhead from unused retainer capacity and no pressure to run additional calls to justify a sunk commitment.

Which Platform Fits Which Engagement?

The honest answer is that GLG and Nexus are not direct substitutes. They solve different problems for different buyer profiles. Here is how to think about the decision.

Choose GLG When

• You need multi-format research: calls, surveys, events, qualitative sessions, and a reusable content library in one platform.
• Your team runs high-volume, broad-coverage research and can justify an annual commitment or large credit block.
• You are at a large hedge fund, global consulting firm, or law firm with established GLG procurement relationships.
• Your brief covers a topic well-represented in a generalist database: consumer markets, broad financial services, large-cap healthcare.
• Platform integration matters: GLG’s content is available through Bloomberg Terminal and FactSet, which may matter for how your team accesses research.

Choose Nexus When

• Your brief requires a genuinely niche or hard-to-find expert profile that a standing database is structurally unlikely to surface.
• You need a Big 4 director with specific transaction history, a former regulator in a defined jurisdiction, or a technical lead with direct operational experience in a narrow vertical.
• You are running due diligence on a compressed timeline and cannot afford irrelevant shortlist entries burning time on screening calls.
• You want per-project pricing with no annual commitment, no expiring credits, and no overhead from unused retainer capacity.
• You want senior-level attention on your engagement, not routing through a large associate workforce.
• Your research volume is variable or project-specific rather than continuous throughout the year.

Frequently Asked Questions

Is Nexus Expert Research cheaper than GLG?

On a per-engagement basis, Nexus is typically more cost-efficient for teams with variable or project-specific research needs. GLG’s effective per-call rates run between $1,500 and $2,500 per hour based on third-party benchmarks, and most clients are onboarded via annual retainers or credit packs. Nexus charges per project with no minimum commitment, so teams pay only for what they use.

Does Nexus have the same compliance standards as GLG?

Nexus screens every expert against the specific engagement before any call takes place. GLG operates a mature, audited compliance infrastructure built over 25 years, which is a genuine advantage for highly regulated clients such as public-markets hedge funds. Teams with strict MNPI or insider-trading compliance requirements should evaluate both frameworks directly against their internal policies.

Can Nexus handle the same volume as GLG?

Nexus is purpose-built for quality over volume. GLG is the right choice for teams running dozens of expert calls per month across multiple simultaneous mandates. Nexus is better suited for teams that prioritize shortlist precision and senior-level project management over raw throughput. If your team needs both, some buyers use GLG for high-volume generalist coverage and a specialist firm like Nexus for the briefs that require genuine recruiting effort.

What types of experts does Nexus specialize in?

Nexus specializes in profiles that standing databases are unlikely to surface: Big 4 directors with specific transaction or sector history, former regulators in defined jurisdictions, technical leads with direct operational experience in narrow verticals, and senior operators in geographies where passive opt-in networks have limited coverage.

How long does it take Nexus to source an expert?

Timeline depends on the complexity of the brief. For well-defined profiles in accessible markets, Nexus typically delivers an initial shortlist within a few business days. For genuinely hard-to-find specialists, the recruiting process takes longer than a database match but produces higher relevance. Nexus confirms expected timelines at the brief stage before any engagement begins.
