Comparing Arbolus and GLG as an expert? Here's an honest look at how they differ.
Arbolus vs. GLG: how they compare for experts
GLG (Gerson Lehrman Group) is one of the oldest and largest expert networks in the world, with a huge pool of experts and a well-established reputation among institutional clients. Arbolus is a newer, more focused platform built specifically around B2B technology and software markets. Both are legitimate, and both can be worthwhile, depending on what you're looking for.
GLG | Arbolus | |
|---|---|---|
Scale | Extremely large network, broad industry coverage | Smaller, more focused network, concentrated in B2B tech and software |
Cost to experts | Free to join | Free to join |
How you get matched | Network sources and invites you to relevant projects | Network invites you to relevant projects, and you can also browse and apply to open projects yourself |
Project types | Primarily one-on-one calls, plus surveys and events | Expert calls, video questionnaires (Canopy), surveys and software reviews |
Payment model | Per-call or per-project, rate typically set per engagement | Per-project, plus ongoing payouts for software reviews |
Ongoing earnings | Paid per engagement, no ongoing component | Experts can qualify for the Rewards Programme and earn per software review |
Best suited to | Experts with broad, cross-industry experience wanting high call volume | Experts with specific B2B software or tech experience |
Where GLG has the edge
Scale is GLG's biggest advantage. With one of the largest expert pools in the industry, it tends to generate a high volume of project invitations across a very wide range of sectors, which suits experts who want frequent opportunities regardless of specific niche. Its size also means broader brand recognition among clients, which can translate into a steadier stream of work.
Where Arbolus has the edge
Arbolus gives experts more agency in how they find work. Arbolus experts can qualify for the Rewards Programme by submitting reviews, meaning a review can keep earning you money each time a client views it, without any extra outreach or negotiation on your part. It's also worth noting that rather than waiting entirely to be selected, you can actively browse and apply to open projects that match your background, which suits experts who prefer not to sit passively in a pool.
The honest takeaway
If your expertise spans broad industries and you want maximum call volume with minimal setup, GLG's scale is hard to match. If your background is specifically in B2B software or technology, and you'd value more say in which projects you pursue plus a built-in route to ongoing income, Arbolus is for you, but joining both isn't mutually exclusive.
