7 Engagement Types Inside Modern Expert Networks: A Buy-Side Buyer's Map

The expert-network category is still discussed as if it were a single product: the one-hour phone consultation, billed in credits, scheduled through a relationship manager. In practice the engagement menu has fanned out, and procurement teams at hedge funds, private equity firms, and corporates increasingly need a taxonomy to match research questions to the right contract structure. This piece maps seven distinct engagement types that buy-side firms buy today, each with the providers known to offer it, the typical pricing structure, and the research question it best answers.

1. The Classic One-Hour Phone Consultation

The one-hour moderated call is still the volume backbone of the category and the product most analysts mean when they say expert network. A research analyst submits a project brief, the network recruits and compliance-screens experts (typically former operators, channel participants, or domain specialists), and a 60-minute call is scheduled, often within 48 hours. Pricing on the buy side typically lands in the USD 1,000 to 1,500 per hour range, billed either as credits drawn from a subscription pool or against a transactional rate card. Providers operating at scale in this format include GLG, Guidepoint, AlphaSights, Third Bridge, Coleman Research, and Dialectica.

The research question this format answers best is narrow and targeted: a specific diligence question on a named company, a channel check during earnings season, an ex-employee perspective on a product roadmap, or a single-thread question on pricing dynamics in a regional market. It is poorly suited to anything that requires N greater than a handful, or to broad market sizing, where one expert's view is one data point.

2. Moderated Custom Surveys and Quantitative Panels

When the research question is statistical (market sizing, pricing studies, NPS benchmarking, share-of-wallet work), the one-hour call format breaks down. Networks have responded with moderated survey products that recruit qualified respondents from the same expert pool, then field a structured questionnaire, often with a quantitative panel of 30 to several hundred respondents. Examples include Third Bridge Forum survey work, GLG Qual/Quant, AlphaSights' survey offering, and Guidepoint Qsight-style products in healthcare.

Pricing here is project-based rather than per-hour, scoped against panel size, screening criteria, and turnaround. The research question this fits: how many independent pharmacies in the US Midwest currently stock product X, what is the average reorder cycle, and what would shift them to a competitor. A single one-hour call cannot answer that. Thirty screened pharmacists on a structured survey can.

3. In-Person and Site-Visit Engagements

A subset of diligence work cannot be done over Zoom. Factory tours, clinic visits, dealer ride-alongs, retail mystery-shop programs, and on-site operator walkthroughs all require physical presence, often with travel logistics handled by the network. Coleman Research, Dialectica, and AlphaSights are among the firms that arrange this kind of work, and it shows up most often in private equity commercial due diligence, deep-dive industrials coverage, and healthcare provider research.

Pricing is materially higher than a phone call (travel, expert day-rates, and coordination time all sit on top of the underlying expert fee), and engagements are typically scoped as projects rather than billed per hour. The research question this fits: validating throughput claims at a manufacturing site before signing an LOI, observing patient flow inside an ASC before underwriting a roll-up, or sitting in a dealer's back office during a typical sales week to see what the CRM data does not capture.

4. Pre-Recorded Interview Libraries

The most structural change to the category over the last five years has been the rise of on-demand transcript libraries: a flat-subscription product where the buyer reads expert interviews that have already been conducted and compliance-cleared, rather than commissioning a new call. Tegus pioneered this model with a buy-side analyst audience, and AlphaSense acquired Tegus in 2024, with the combined library now exceeding 150,000 expert call transcripts inside AlphaSense Expert Insights.

Pricing is a flat seat-based subscription with no per-call charge, which inverts the economics of the live-call model. The research question this fits sits at the top of the funnel: idea generation, fast onboarding to a new sector, pre-read before commissioning a live call, and pattern-matching across multiple operators' views on the same topic. Analysts who lean on libraries tend to use the live-call format more selectively afterwards, because the obvious questions have already been answered in transcripts.

5. Long-Term Advisor and Retained-Expert Arrangements

Not every expert engagement is a one-shot. GLG Council Member retainers and Guidepoint Advisors are examples of multi-month arrangements where a single expert is engaged on an ongoing basis, typically with defined deliverables: board observer roles inside a PE portfolio company, fractional CTO support during a technology integration, ongoing advisory on a consulting project, or recurring monthly check-ins through the life of an investment.

Pricing is monthly rather than hourly, and contracts often include a deliverable schedule (briefing memos, periodic written updates, attendance at board or operating reviews). The research question this fits is rarely a research question at all in the buy-side sense. It is operational support: a private equity firm needs continuous expert oversight on a portfolio company's commercial transformation, and the expert network is the cleanest way to source and contract for that expertise without bringing it in-house.

6. Project-Based and Consulting-Style Engagements

The boundary between expert networks and management consultancies has narrowed. Guidepoint Qsight in healthcare data, GLG Research, Dialectica's commercial due diligence teams, and newer entrants such as Bridgetown Research with AI-augmented strategy work are all scoped and sold as projects, not as per-call inventory. A typical engagement is a five- or six-figure project with a defined scope (market sizing, competitive landscape, customer voice study, pricing strategy review), a project team, and a written deliverable.

Pricing is project-based and the buyer is often a corporate strategy team, a PE deal team, or a hedge fund PM funding a deeper-than-usual piece of pre-trade work. The research question this fits: a 6 to 10 week piece of work that would otherwise have been bid out to a Tier 2 consultancy, where the expert network's advantage is faster access to operators and a lower hourly economics base.

7. MCP and API Access for AI Agents

The newest engagement type, and the one most likely to reshape 2026 procurement conversations, is direct programmatic access to transcript libraries for AI agents and internal research tooling. Guidepoint launched an MCP server on Claude with access to more than 100,000 transcripts in late 2025 and early 2026, GLG content has been integrated into Bloomberg ASKB, and AlphaSense Assistant exposes the combined AlphaSense and Tegus corpus to agentic workflows.

Pricing is structured as enterprise data access (annual contract, seat or query-based licensing, distinct from per-call expert spend) and the buyer is increasingly a head of research or a head of data rather than the analyst commissioning a single call. The research question this fits is everything an analyst would otherwise have asked of a junior researcher: pull every transcript where operators discussed pricing power in the freight brokerage segment, summarise the bear case across five recent calls on a single ticker, surface dissenting views from former employees on a named company. The economics, governance model, and procurement workflow for this layer all differ from the human-call inventory it sits next to, which is why it is showing up as a separate line item in 2026 budgets rather than being bundled into existing subscriptions.

How to Use the Map

The seven engagement types are not substitutes for each other. They are different products that answer different research questions, and the most sophisticated buy-side teams use four or five of them in combination: libraries for top-of-funnel, live calls for targeted diligence, surveys when N matters, site visits when physical presence matters, retainers when the engagement is operational rather than analytical, project work when the scope exceeds what calls can deliver, and MCP access when the analyst wants the library inside their own tooling rather than inside the vendor's UI.
