expertOS vs GLG
The largest traditional expert network — a vast roster of advisors you book and pay for by the hour.
A fair read on GLG.
GLG (Gerson Lehrman Group) pioneered the expert-network model: a huge, recruited council of professionals that clients pay to consult, usually through a subscription or retainer plus per-call fees. A research manager matches you to experts, schedules the calls, and you take it from there.
Where GLG is strong
- Enormous, deeply specialised expert roster across nearly every industry and geography.
- Mature compliance program and account management trusted by large enterprises and investors.
- Strong for hard-to-reach, niche human sources when you already know what to ask.
- Decades of brand trust with the largest buyers of primary research.
Where it leaves gaps
- Priced for the enterprise — subscriptions, retainers, and per-call minimums add up fast.
- You still do the synthesis: GLG connects you to people, it doesn’t hand you a sourced answer.
- A call is the default unit of work, even when a quick verified fact would have done.
- No AI research layer that tells you where a call is actually worth making.
- Scheduling and routing run through account managers, not a self-serve agent.
The answer — not just access.
An agent that knows when a call is worth making
expertOS researches first, answers from verified sources, and only routes you to a paid expert for the gaps it genuinely can’t close — so you’re not booking a call for something a citation could settle.
Pay only for the knowledge you’re missing
No subscription, retainer, or per-call minimum. You spend on the specific expertise you actually need — positioned roughly 70% below legacy networks.
Honest by default
Every claim is tagged verified, inferred, or unknown. You see exactly what’s grounded and what still needs a human — instead of a transcript you have to vet yourself.
AI-moderated calls + synthesis
When a call does happen, an AI moderator can run it on your discussion guide and hand back a transcript plus a one-click synthesis across every expert.
Every answer is tagged for how well it’s grounded.
Grounded in primary sources you can check.
A reasoned read — flagged so you know where to dig.
Not yet known — where a routed expert call earns its keep.
The same three-signal honesty runs through every expertOS answer — and into the call when one is needed.
Quick answers when GLG comes up.
GLG sells you access to people. expertOS sells you the answer — and a call only when it’s the cheapest way to get one.
