GLG alternatives include expert networks such as AlphaSights, Guidepoint, Third Bridge, Dialectica, Coleman Research and Nextyn, the Tegus transcript library from AlphaSense, and NewtonX for B2B surveys and interviews. The right choice depends on whether you need new expert calls, existing transcripts or survey data, and on the regions and sectors your questions cover.
GLG alternatives fall into three groups
The firms buyers compare with GLG do different jobs, so it helps to sort them first.
- Other expert networks such as AlphaSights, Guidepoint, Third Bridge, Dialectica, Coleman Research and Nextyn recruit experts to your question and arrange one to one calls.
- Transcript libraries such as Tegus, and the libraries inside Guidepoint, Third Bridge and AlphaSights, give you access to calls already held, so you can read before you book.
- B2B research firms such as NewtonX recruit and verify professionals for surveys and interviews.
GLG's website covers all three groups, so a comparison works format by format.
What GLG offers, from its own website
GLG presents itself as a platform for trusted human expertise. Its How We Help pages cover expert calls and meetings, expert content, research, events, and advisory and placements.
Expert calls and meetings include private conversations, AI moderated calls and in person meetings. Expert content is a library of transcripts, including interviews, rapid insights from many experts and roundtables. Research covers surveys, expert led studies and sample sourcing. Advisory and placements covers deal advisors, board directors, fractional placements and expert witnesses.
Clients work through myGLG, and GLG says its calls run inside expert verification processes and built in compliance frameworks. Its website lists private equity firms, hedge funds, investment banks, consulting firms, corporations and law firms, and shows offices in the Americas, EMEA and Asia Pacific. It does not publish pricing; the route in is a Get started form.
Companies like GLG, compared side by side
The table summarises each firm from what it says on its own website. Where a site does not say something, the table does not either.

GLG vs Tegus: expert calls against a transcript library
GLG vs Tegus is a comparison of two models more than two competitors. GLG's core offer is access to experts for new calls, with a transcript library called Expert Content alongside. Tegus is built around a library of transcripts from past expert calls, and its website states that Tegus is now part of AlphaSense.
With a library, you search, read and compare calls already held, and you can start without waiting for a booking. With a new call, you choose the expert and put your own questions to them. A library suits a question that earlier calls may already answer, and a new call suits a question specific to your thesis.
The two overlap. Tegus lists expert call services next to its library, and GLG offers transcripts next to its calls. Read as Tegus vs GLG, the comparison is the same. Our guide to expert call transcript libraries compares the libraries in more detail.
GLG vs NewtonX: expert calls against B2B surveys and recruitment
GLG vs NewtonX is a comparison between an expert network with a research arm and a research firm built around recruitment. NewtonX describes itself as a B2B market research company. Its website lists surveys, interviews, AI moderated research and custom recruitment, and says participants are identity verified.
For B2B executive surveys, both firms field surveys to professionals. GLG describes a survey it designs and fields, an expert led study it runs from design to report, and sample sourcing for teams with their own survey. NewtonX describes a process that runs from strategy through execution and analysis to reporting.
For in depth interviews, NewtonX describes phone consultations, video interviews, focus groups and advisory boards recruited to your criteria. GLG offers private expert calls and can custom recruit experts when a question requires it. Ask which one your quote covers and how each participant is screened.
Alternatives to GLG for private equity
A private equity team comparing alternatives to GLG is usually weighing three things: calls inside a short diligence window, transcripts the team can reread, and a screening record an investment committee can review. Most of the firms in the table name private equity or institutional investors among their clients.
Because every expert network in the table runs expert calls, the differences for a deal team are sector coverage, speed to first profiles, the screening record and any surveys or library. Our guides to expert networks for private equity and senior advisor networks for private equity go further, and our private equity page explains how Nextyn works with deal teams.
How to compare a GLG alternative
Run the same short brief with two or three firms and compare the results.
- Coverage: whether the firm can reach the seats and countries your question needs.
- Speed: how soon after a brief you see the first expert profiles.
- Screening: how experts are checked for conflicts and confidential information, and the record you receive.
- Format: whether you need new calls, a library, surveys or all three.
- Pricing model: whether you pay per call, under a subscription or against a prepaid agreement.
None of the firms in the table publishes rates, so ask each how it charges and what moves the price: seniority, how rare the profile is, the format, the geography and compliance requirements. Our guides to expert network pricing and expert network compliance cover both, and our overview of expert networks lists the main firms.
