🟢 Updated May 2026Quick Overview

Consulting marketplaces (Catalant, Expert360) sit between — blending access to ex-consulting talent with project execution capabilities. Choosing the right category before comparing individual platforms will save you weeks of research.

Platform Summaries
GLG (Gerson Lehrman Group)
GLG is the world's largest expert network, with over 1 million professionals available for 30–60 minute phone consultations. Founded in 1998, it has become the default choice for investment firms, consultancies, and Fortune 500 strategy teams conducting due diligence, market entry analysis, and competitive intelligence. The platform operates exclusively on annual enterprise contracts, with no pay-per-call or SMB-accessible pricing. Its strength is depth of expertise across niche sectors — you can reach a former regulator, a retired pharma exec, or a factory floor manager within hours. The annual commitment and compliance-grade expert vetting are non-negotiable for clients who need confidentiality.
AlphaSights
AlphaSights differentiates from GLG through a client service model that emphasizes speed and sector depth. With around 75,000 active experts, it focuses on connecting knowledge-seeking clients with professionals who have recent, hands-on experience in specific industries. The platform is particularly strong in Asia-Pacific and Middle Eastern markets, where its global coverage and local expertise networks outpace competitors. Annual contracts start lower than GLG's, making AlphaSights a viable step-in for mid-market companies that need research-grade expert access without GLG's $50K+ minimums.
Guidepoint
Guidepoint is a research-focused expert network with 100,000+ experts, emphasizing expert quality and client service. It competes directly with AlphaSights in the mid-enterprise tier, offering similar annual contract models with slightly lower entry points. Guidepoint's network includes former executives, sector specialists, and technical practitioners — with particular strength in healthcare, technology, and financial services. The platform also offers Advisory Services, which go beyond one-off calls to provide structured research engagements and advisory boards of multiple experts.
Toptal
Toptal is a talent marketplace, not a research network — the distinction matters. You hire Toptal professionals to execute work: build software, design a product, model financial projections, or serve as a fractional CFO. Toptal's ~3% acceptance rate screens for top-tier talent, and clients get a two-week trial with a money-back guarantee before committing to longer engagements. Rates range from $60/hour for junior developers to $350/hour for senior finance experts. There is no annual contract requirement — you pay per engagement. Best for companies that know what they need built and need a vetted expert to build it.
Catalant
Catalant occupies the space between research networks and full-service consultancies. Its network of 30,000+ includes ex-McKinsey, Bain, and BCG consultants who take on project-based work — strategy, operational transformation, financial modeling, and market entry planning. The platform offers flexible pricing: per-project, hourly, or subscription models with lower entry points than GLG. Catalant's differentiator is the quality of talent relative to cost versus traditional consulting firms, with engagements typically running weeks to months. Suitable for mid-market companies that need strategic work executed by people who've done it before at top firms.
Expert360
Expert360 is the leading expert network in Asia-Pacific, with 15,000+ transformation and operations specialists. Originally focused on Australia and New Zealand, it has expanded across APAC and competes globally in specific verticals: digital transformation, supply chain, HR transformation, and operational excellence. Expert360's experts tend to be former operators — people who have run functions, not just advised on them. Pricing is flexible, with per-project and hourly options that are more accessible to SMBs than GLG's enterprise contracts. Best for companies with APAC operations or transformation needs in sectors where Expert360's network is deepest.
