GLG (Gerson Lehrman Group)
GLG is the largest expert network by revenue, primarily serving hedge funds, private equity firms, and enterprise strategy teams. They have 1M+ experts on their network and specialize in short expert calls (1 hour) for primary research and due diligence.
For small business: GLG's annual subscription model (typically $25K–$100K+) is designed for institutional buyers. An SMB needing occasional consulting advice will find the cost structure impractical.
Catalant
Catalant focuses on project-based consulting for mid-market companies and enterprise teams that want independent consultants over Big Four firms. Projects typically run $10,000–$100,000+.
For small business: Catalant's consultants are credentialed and experienced, but the platform is oriented toward larger projects. Smaller engagements ($5K–$15K) are possible but not the primary use case.
Toptal
Toptal curates the top 3% of freelancers across engineering, design, and finance. It's the best network for technical talent (developers, designers) and financial modeling specialists who work on a project or part-time basis.
For small business: Strong fit if your need is technical. Less suited for operational consulting, fractional executive roles, or domain-specific expertise outside engineering and finance.
Expert360
Expert360 focuses on strategy, operations, and transformation consultants across Australia, APAC, and increasingly North America. The platform is project-oriented with vetted consultants.
For small business: Good option if your consulting need is clearly scoped as a project. Less infrastructure for fractional ongoing relationships.
ExpertStackHub
ExpertStackHub is built specifically for SMBs and growth-stage companies that need fractional executives (CFO, CTO, CMO, CHRO) and specialized consultants — without enterprise minimums or long procurement cycles. The AI matching system identifies experts based on company stage, business model, and specific outcomes needed (not just seniority level).
For small business: The most direct fit for SMBs hiring fractional executives or specialized consultants on an ongoing basis.
How to Choose the Right Network
- Need an expert call for research or due diligence? GLG is the industry standard, but expect enterprise pricing.
- Need a defined consulting project? Catalant or Expert360.
- Need technical freelancers? Toptal.
- Need a fractional executive or ongoing specialized consultant? ExpertStackHub.
Pro tip: For most SMBs, the most cost-effective approach is to start with a scoped engagement (defined outcome, defined hours) rather than an open-ended retainer. Use our AI Expert Match to define your need before approaching any network.
Frequently Asked Questions
What is an expert network?
An expert network is a platform that connects businesses with independent consultants, fractional executives, or subject-matter experts for project work, advisory calls, or ongoing engagements. Networks vet experts, handle contracts, and sometimes provide matching services.
Are expert networks worth it for small businesses?
Yes, if you need specialized expertise you can't hire full-time. Expert networks give you access to senior talent — CFOs, CMOs, cybersecurity experts — at fractional cost. Enterprise-focused networks often have high minimums that make them impractical for SMBs; SMB-friendly networks have lower entry points.
How much do expert networks charge?
Expert networks typically charge experts a platform fee (15–30%) and sometimes charge companies a subscription or per-engagement fee. Hourly expert rates range from $150–$500+ depending on the network and expert seniority.
