Expert Networks for Consulting Firms
How management consultancies use expert networks — and which providers are best suited for client engagements, market sizing, competitive analysis, and industry research.
How consulting firms use expert networks
Management consulting firms are among the largest buyers of expert network services. Unlike investors who use experts primarily for due diligence, consultancies integrate expert calls across the full engagement lifecycle — from proposal development and market sizing through to recommendation validation and implementation support.
Key requirements for consulting teams include:
- Volume and breadth — Large strategy firms may run hundreds of expert calls per month across dozens of concurrent engagements.
- Global coverage — Client engagements span geographies. Providers with strong international expert networks are essential.
- Industry depth — Consultancies need experts across every sector, from healthcare and technology to industrials and consumer goods.
- Surveys — Quantitative expert surveys complement qualitative calls for market sizing and hypothesis validation.
- Cost management — At high volumes, per-call costs matter. Enterprise pricing and annual agreements are common.

Choosing the right provider for your firm
The right expert network for a consulting firm depends on firm size, engagement mix, and research workflow:
- Large strategy firms (MBB, Big Four) typically use GLG as a primary provider for breadth and scale, supplemented by AlphaSights for speed-sensitive work and specialized providers for niche sectors.
- Mid-tier firms often prefer Guidepoint or Atheneum for competitive pricing and flexible engagement models without large annual commitments.
- Boutique consultancies benefit from per-project pricing and may find value in newer technology-first platforms that offer lower cost per call.
