GLG vs Catalant: Expert Networks Compared for SMBs (2026)
GLG costs $750–$1,500/hr with enterprise minimums. Catalant takes 20–30% commission. Here's what that means for SMBs.
GLG charges the equivalent of $750–$1,500 per hour for expert calls, accessed through an annual membership starting at $25,000+. Catalant takes a 20–30% commission on every consulting engagement. Both are built for enterprise teams with procurement budgets to match. If you're an SMB or growth-stage company, you're largely shut out of both.
This guide breaks down exactly what GLG and Catalant cost, what they're actually good for, and when an AI-matched alternative is the smarter call.
The Short Answer

|---|---|---|---|
| Primary use case | Expert calls for due diligence & research | Project-based consulting engagements | Fractional executives & specialized consultants |
| Cost model | $25K–$100K+/yr membership | 20–30% platform commission on consultant fees | No minimum, no client commission |
| Expert call rate | $750–$1,500/hr equivalent | N/A (project-based) | $175–$375/hr (transparent, direct) |
| SMB-accessible? | No | Marginally | Yes |
| Time to first match | 24–48 hours (once contracted) | 3–10 days | Minutes (AI-matched) |
GLG: What It Actually Costs
GLG (Gerson Lehrman Group) is the world's largest expert network by revenue. It's the default tool for hedge funds, private equity firms, and corporate strategy teams running primary research. The business model:
- Annual enterprise membership ($25,000–$500,000+/year)
- A credit system that governs expert access — credits refresh with contract renewal
- Expert calls typically 30–60 minutes; per-call value in the $750–$1,500+ range
- Mandatory expert compliance training to manage inside information risks
For the right buyer — a PE firm doing 200+ expert calls per year across investment theses — GLG is worth the cost. The breadth of their expert network (1M+ professionals) is genuinely hard to replicate.
For anyone else: the economics don't work. GLG doesn't offer pay-per-call access. If you need three expert calls for a strategic project, you're not the customer they've built for.
Catalant: Understanding the Commission Model
Catalant is a project-based consulting marketplace connecting enterprises with independent consultants — primarily former McKinsey, Bain, BCG, and Big Four professionals. The key pricing mechanics:
- Consultant rates: $150–$450/hr depending on specialty and seniority
- Platform commission: Catalant takes approximately 20–30% of engagement value, built into the rate consultants quote
- Typical project size: $15,000–$100,000+ for meaningful engagements
- No annual contract required — projects are on-demand
The practical implication: a project that costs you $30,000 might involve a consultant who's netting $21,000–$24,000 after Catalant's take. You're paying a premium for the marketplace infrastructure — vetting, proposal management, contracts, enterprise procurement tooling.
Catalant is a legitimate option for a well-scoped strategic project if your budget supports it. It becomes impractical when your need is ongoing (fractional executive), when your budget is under $10,000, or when you need speed over polish.
Head-to-Head: When Each Platform Wins
| Scenario | Better Choice | Why |
|---|---|---|
| Investment due diligence: 10 expert calls in 2 weeks | GLG | Unmatched expert breadth, compliance controls, speed |
| 6-week market entry strategy project | Catalant | Project-scoped work with ex-Big 3 methodology |
| Ongoing fractional CFO, 15 hrs/month | ExpertStackHub | No commission, no minimums, AI-matched to your stage |
| SMB needing specialist for a $5K project | ExpertStackHub | Neither GLG nor Catalant serve this budget |
| Enterprise running 50+ expert calls/year | GLG | Annual membership is cost-efficient at volume |
| Corporate development, post-merger integration | Catalant | Strong ex-MBB talent for defined deliverable work |
Who Should NOT Use GLG
If you're in any of these situations, GLG is almost certainly the wrong tool:
- You need fewer than 20 expert calls per year
- Your annual consulting/research budget is under $50,000
- You're looking for someone to do work, not answer questions on a 45-minute call
- Your company is pre-Series A or under $5M ARR
- Your need is a fractional executive, not a research informant
For these scenarios, the GLG annual contract cost exceeds the value you'd extract by a significant margin.
Who Should NOT Use Catalant
- Your project budget is under $8,000–$10,000
- You need ongoing advisory (retainer/fractional) rather than a discrete project
- You're pre-product and still defining the problem — Catalant's model requires a clear scope
- You're a startup that can't afford the ex-MBB premium and needs domain expertise over consulting methodology
The SMB Case for AI-Matched Expert Access
Both GLG and Catalant were built for enterprise buyers. They're structurally not optimized for SMBs — their pricing, minimum commitments, and procurement complexity all skew toward Fortune 500 procurement teams.
