How to Use an Expert Network

Most expert network buyers learn by getting burned on the first three projects. This guide compresses that learning into the fundamentals that matter — how to brief, how to scope, how to spot a bad call early, and how to extract real value from the engagement.

00/TL;DRSkip-friendly summary

The brief is the lever. Bad briefs make bad calls inevitable. Spend 30 minutes on the brief before the first call and you'll cut your dud-call rate in half.

01/What an expert network actually is

An expert network is a marketplace that connects buyers (funds, corporates, consulting firms) with vetted operating professionals (current and ex-employees, specialists, advisors) for paid 1:1 consultations. The network handles sourcing, vetting, scheduling, compliance and payment. Pricing is typically per-call (€500–€1,500) or via subscription/retainer models. The largest players are GLG, AlphaSights, Guidepoint, Third Bridge, Tegus. Boutiques like FieldSignal sit alongside them with different economics and service models.

02/When to use one vs alternatives

Use an expert network when you need direct primary-source insight — operator experience, channel reality, customer perception — that you cannot buy as a packaged report. Don't use one when secondary research will suffice (analyst reports, broker research, public filings), when you need quantitative data at scale (use survey panels), or when the question is so narrow you already know the right person to call (just call them directly).

03/Writing a brief that gets you the right experts

The brief drives expert quality more than any other factor. A weak brief produces weak experts no matter how good the network is. A strong brief includes: the decision being made (not just the topic), the 5-7 specific questions you need answered, the type of expert (role, seniority, geography), the experts to AVOID (former employer X, named competitors), and a kill-criterion that ends the project if certain findings emerge. Spend 30 minutes on this — it's the highest-leverage 30 minutes of the project.

04/Scoping the project correctly

Most first-time buyers over-scope. Five well-prepared expert calls almost always beat fifteen rushed ones. The exception is when you're triangulating noisy or contradictory data — then volume matters. Default: 5–10 calls for a focused question, 15–25 for a market sizing or channel research project, 25+ for full commercial diligence sprints.

05/Compliance — what to know before the first call

Reputable networks all enforce: MNPI exclusion (no discussion of material non-public information), 6-month cooling-off for public-company former employees, NDA disclosure, conflict-of-interest screening and per-call attestation. Read your vendor's compliance framework before procurement signs the MSA — if any of those five elements are missing, escalate. Compliance corners get cut at the cheaper end of the market.

06/What good deliverables look like

If you're paying for white-glove service, expect: an anonymised expert profile delivered before the call (so you can prep), the call itself with the senior researcher dialled in (not just an analyst), notes or a transcript within 48 hours, and a synthesis document if you've bought a project-level engagement. If you're paying per-call only, you handle the synthesis — that's fine, just know what you're buying.

07/Spotting a bad call early

First five minutes are diagnostic. The expert should be able to articulate their direct experience with the topic in under 90 seconds. If they're hedging, citing public sources, or sounding like a consultant explaining the category from analyst reports, end the call politely and ask the network for a replacement. Networks expect this; senior researchers will surface a replacement within 24 hours.

08/Getting real value out of the engagement

The best buyers do three things: (1) read your own internal notes from prior calls before each new one so you don't ask the same opening questions, (2) follow up with the network when you notice patterns across calls — they can target new experts on the emerging hypothesis, and (3) close the loop after the decision — tell the network what you decided and why, so they get smarter about your buying criteria.
