GLG alternatives: 10 best expert networks and platforms in 2026
GLG is the largest traditional expert network, but it is not the only option. Here are 10 alternatives across enterprise networks and modern on-demand platforms, with a comparison table to help you pick.
Looking for a GLG alternative? The best options in 2026 are AlphaSights, Guidepoint, Third Bridge, Tegus, NewtonX, Coleman Research, proSapient, and Atheneum among traditional expert networks, plus modern on-demand platforms like CleverX that give you self-serve access to verified professionals without a retainer. The right choice depends on whether you want relationship-managed enterprise service or fast, pay-as-you-go recruiting.
GLG (Gerson Lehrman Group) is the largest and best-known expert network in the world, and for many use cases it is an excellent choice. But it is not the only choice, and it is not always the right one. This guide describes GLG honestly, then walks through 10 alternatives so you can match a provider to your budget, timeline, and research goals.
What GLG actually is, and why teams look elsewhere
GLG pioneered the modern expert network model. It maintains one of the largest councils of vetted experts in the world and connects investors, consultants, and corporate strategy teams with those experts for phone consultations, surveys, and advisory work. Its strengths are real: enormous scale, deep coverage across industries and geographies, mature compliance infrastructure, and dedicated account teams that manage sourcing for you.
Those same strengths shape the trade-offs. GLG is built for enterprise buyers. Engagements are typically relationship-managed and retainer-oriented, compliance review adds process, and pricing usually sits behind a sales conversation with minimum spend commitments. That model is a great fit for a large investment firm running continuous diligence. It can feel heavy for a product team that needs to talk to eight B2B buyers next week, or a startup that wants a handful of expert conversations without signing an annual contract.
If you want the full landscape before you decide, our complete comparison guide to expert network platforms and this breakdown of how companies connect with industry specialists are good starting points.
How to choose a GLG alternative
Before comparing vendors, get clear on four things:
Use case
Investment diligence, management consulting, and corporate strategy have different needs than product discovery, message testing, or B2B market research. Networks like AlphaSights and Guidepoint index toward finance and consulting. On-demand platforms index toward operators, buyers, and practitioners you can survey or interview at speed. Our guide to expert interviews for investment and consulting research covers the diligence side in depth.
Speed
Traditional networks often deliver an expert in a few business days once a project is scoped, but scoping and compliance add lead time. On-demand platforms compress this because you recruit directly from a live panel.
Commercial model
Retainer and per-call pricing suit teams with continuous, high-volume needs. Pay-as-you-go credits suit teams with spiky or project-based needs who do not want an annual commitment.
Verification and compliance
Every serious provider vets experts, but the depth and transparency vary. If you need documented identity verification, employment checks, or conflict screening, confirm exactly how each vendor handles it.
The 10 best GLG alternatives in 2026
Traditional expert networks
1. AlphaSights. One of the largest global networks, strongest in private equity, hedge fund, and consulting diligence. Known for fast turnaround, high-touch account management, and a large associate team that sources experts to order. A close structural peer to GLG, with the same retainer-and-service model.
2. Guidepoint. A major network with broad industry coverage and a large expert base, popular with investment and corporate research teams. Offers expert calls, surveys, and events, plus data products. Similar commercial posture to GLG and AlphaSights.
3. Third Bridge. Blends expert calls with a library of pre-recorded interview transcripts (its Forum content). Well regarded in private equity and consulting for combining primary calls with ready-made secondary research from prior expert conversations.
4. Tegus. Best known for its enormous searchable library of expert call transcripts, now widely used by public and private market investors. If your main goal is reading existing expert interviews rather than commissioning new ones, Tegus is often the first stop. It also supports scheduling new calls.
5. NewtonX. Positions itself as a B2B-focused, technology-driven network that identifies experts across a wide professional graph rather than a fixed council. Strong fit for B2B market research and harder-to-source commercial roles, with a custom-recruit model per project.
6. Coleman Research. An established mid-sized network offering expert calls, surveys, and advisory connections across healthcare, industrials, technology, and consumer sectors. Often chosen by firms that want a capable network without the largest-vendor overhead.
7. proSapient. A technology-forward network that pairs a sourcing platform with human research management, aimed at private equity and consulting. Emphasizes software workflow and compliance tooling alongside its expert base.
8. Atheneum. A global network with strong coverage in Europe and Asia, serving consulting, corporate, and investment clients. A solid option if regional reach outside North America is a priority.

Modern on-demand platforms
The second category is not a smaller version of GLG. It is a different model built for self-serve speed, verified panels, and pay-as-you-go access. These platforms suit product, growth, UX, and market research teams as much as investors.
9. CleverX. An on-demand B2B research platform and a modern alternative to traditional expert networks. Instead of routing every request through an account team, you recruit directly from a panel of 8M+ verified professionals, each validated by work email and LinkedIn, across 150+ countries. You launch interviews or surveys yourself, typical delivery runs about 2 to 5 days, and pricing is pay-as-you-go with credits and no retainer. AI Interview Agents can run and transcribe qualitative interviews at scale, so a small team can gather structured insight quickly. It is the strongest fit when you want speed, verified respondents, and control without an enterprise contract.
10. Specialist and DIY panels. Beyond named networks, many teams combine a modern platform with their own recruiting. Our guides on how to recruit B2B research participants and how to recruit C-level executives for research cover the DIY route, which can complement any of the platforms above when you need very specific roles.

Traditional network or on-demand platform?
The honest answer is that both models earn their place, and many teams use both.
Choose a traditional expert network when you run continuous, high-stakes diligence, need dedicated account management, want the deepest possible coverage of niche senior experts, and have the budget for a retainer. GLG, AlphaSights, Guidepoint, and Third Bridge are hard to beat here. If your work is investment or consulting research, that service layer is often worth the premium, and our piece on expert interviews for investment and consulting research explains why.
Choose a modern on-demand platform when speed, cost control, and self-serve access matter more than white-glove handling. If you are testing a product concept, validating messaging, sizing a market, or interviewing buyers, you often need verified professionals in days, not a scoped enterprise engagement. That is where a platform like CleverX fits: verified panel, direct recruiting, AI Interview Agents, and pay-as-you-go pricing. Our walkthrough of expert network services for researchers and professionals compares the workflows side by side.
Many teams end up running a hybrid: a traditional network for deep senior diligence, and an on-demand platform for the high-volume, fast-turnaround research that would be slow or expensive to route through a retainer.
Where CleverX fits
If GLG feels too heavy for your day-to-day research, CleverX is built for the opposite problem. It is an on-demand B2B research platform where you recruit from 8M+ verified professionals across 150+ countries, each verified through work email and LinkedIn, then run interviews or surveys yourself. Typical delivery is about 2 to 5 days, AI Interview Agents help you scale qualitative conversations, and credits mean you pay for what you use with no retainer.
That model suits product managers, UX researchers, growth teams, and market researchers who need reliable primary insight fast. For method guidance, our market research methodology guide and this walkthrough on turning product research into better product decisions pair well with an on-demand recruiting workflow. If your work is heavier on expert interviewing, our overview of B2B market research expert interview methods covers the interviewing craft itself.
Standards bodies like the Insights Association publish research ethics and compliance guidance that applies whichever provider you pick, so verification and consent should be table stakes on any platform you evaluate.

Frequently asked questions
What is the best alternative to GLG?
It depends on your use case. For investment and consulting diligence, AlphaSights, Guidepoint, and Third Bridge are the closest traditional peers. For fast, on-demand access to verified B2B professionals without a retainer, modern platforms like CleverX are a strong fit. Tegus is best if you mainly want expert call transcripts.
Why do companies look for GLG alternatives?
The most common reasons are cost and retainer commitments, slower relationship-managed sourcing, minimum spend requirements, and a preference for self-serve, on-demand access. Some teams also want broader coverage of specific regions, industries, or hard-to-reach professional roles.
Are expert networks worth it?
Yes, when you need primary insight from people who actually do the work, such as buyers, operators, or executives in a specific market. Expert networks and on-demand platforms compress weeks of cold outreach into days by handling sourcing, screening, and compliance for you.
How much do expert networks cost?
Traditional networks typically use annual retainers or per-call pricing, often with minimum spend commitments, and pricing is usually quoted after a sales conversation. Modern on-demand platforms tend to use pay-as-you-go credits, so you pay per completed interview or survey response without an annual contract.
What is the difference between GLG and CleverX?
GLG is a large, relationship-managed enterprise expert network built around retainers and dedicated account teams. CleverX is a self-serve, on-demand B2B research platform where you recruit from a panel of verified professionals, launch interviews or surveys yourself, and pay per response with credits.
Can I switch expert networks without disrupting a project?
Yes. Most teams run a small pilot with a new provider on a single project before moving more spend over. On-demand platforms make this especially easy because there is no annual commitment, so you can test sourcing speed and expert quality on one study first.
