GLG

GLG, the Gerson Lehrman Group, operates as the veteran of expert networks, having built its platform over more than twenty years into a global system that matches institutional clients with domain-specific expertise. The company's core value proposition is straightforward: decision-makers need access to the thinking of practitioners who have spent years in the trenches of their industries, and GLG maintains the infrastructure to make those connections reliable and compliant.

The platform connects clients across financial services, corporate strategy, life sciences, technology, law, and consulting sectors. On the expert side, GLG recruits from across those same industries, building a roster of senior professionals who can speak with authority on their specializations. The company maintains offices spanning the Americas, Europe, India, the Middle East, and Asia-Pacific, which gives the network geographic breadth and helps match experts to clients across time zones and regions.

The engagement models GLG offers to experts are varied enough that different professionals at different career stages can find something that fits. The most common engagement is the expert call, a conversation where a client calls in with a specific question or research need and you spend thirty minutes to an hour on the phone answering it. Beyond calls, GLG also arranges in-person meetings, where you might sit down with a team from a consulting firm or investment bank to work through a problem in real time. Surveys offer another lighter-touch format, letting you contribute written input on a topic within your domain. The network also offers event participation, where you might speak on a panel, lead a roundtable, or host a client tour of your facility or market.

For professionals who want deeper engagement, GLG brokers advisory and placement roles. These are higher-stakes arrangements where you might serve as a deal advisor to a private equity firm, take a board seat at a portfolio company, work on a fractional basis as an embedded expert for a period, provide expert witness testimony, or command a speaking slot at a major industry conference. These roles typically command higher fees and longer commitments than a single call, and they're the entry point for experts who have either the executive standing or the specialized knowledge that makes them valuable as ongoing advisors rather than one-off consultants.

The recruitment process at GLG emphasizes rigor. The platform applies a screening process that examines your relevant experience, pulls proprietary behavioral data, and cross-references third-party sources to confirm the expertise you claim. The vetting is thorough, which matters because GLG's reputation with institutional clients depends on the quality of the experts it puts forward. That same screening process also means the platform won't register you if it can't confirm your background, but it also means when you do get matched to a project, the client has already determined you're credible.

A central appeal of GLG for expert consultants is autonomy in pricing. Rather than the platform setting rates, you establish your own hourly rate based on what you think your expertise is worth and what you see the market bearing. This contrasts with some other expert networks where either the platform negotiates rates project by project or sets them centrally. At GLG, if you think your deep experience in biotech manufacturing or emerging market hedge fund strategy is worth $500 per hour, you set that rate. Clients see it, and project managers assess whether the budget fits. You're paid upon project completion, which means you don't have to wait for a quarterly settlement or chase payments through a convoluted process.

The practical experience of working with GLG involves flexibility balanced against reliability. The platform provides a mobile app that lets you review opportunities as they come in, and responsiveness matters. Experts who respond quickly to project invitations get selected more often than those who let opportunities sit in their inbox. There's no minimum engagement commitment, no exclusive arrangements that prevent you from working with other consultants or expert networks, and no penalty for declining a project that doesn't fit your schedule or expertise. You're a sole proprietor setting your own schedule, and GLG acts as the intermediary connecting you to demand.

Conflict management is a component of the GLG infrastructure that becomes important as you work more. The platform maintains a conflicts and compliance system that screens engagements to ensure you don't find yourself advising a client on a deal involving your employer, a competitor, or a company where you hold a board seat or own significant equity. These barriers exist to protect your employer's interests (consultations are usually permitted under employer policies, but competitive conflicts can be thorny), and they also protect the client from advice colored by undisclosed conflicts. GLG handles the vetting, but you're responsible for being upfront about your affiliations when you set up your profile.

The platform's scale reinforces the opportunity flow. GLG's institutional client base includes some of the world's most sophisticated firms, asset managers, and corporations, which means there's consistent demand for expert input. If your expertise aligns with active research questions, you can field multiple opportunities a month. If your specialty is more niche, you might get calls infrequently, but when they come they tend to be high-value engagements with serious clients who are willing to pay premium rates for genuine expertise.

One practical consideration is that GLG's model rewards specialization. You don't need to be a household name or a published author, but you do need to have real experience and a clear story about why you know your domain. An operations executive who spent twelve years at a major manufacturer, then moved to a consulting role, has a more compelling profile than a generalist who touches everything. You're selling your specific knowledge, not your general business acumen.

The network's longevity in the industry also means the platform has refined its processes over time. The approval and payment systems are stable, compliance protocols are established, and the platform has learned how to match clients and experts effectively. You're not betting on an early-stage startup whose infrastructure might fail or whose terms might shift; you're working with a platform that has been doing this for decades and refined the model repeatedly.

GLG appeals most to senior professionals who have built genuine expertise over years in their industry, have time available for consulting engagements outside their full-time role (or are entrepreneurial enough to make consulting a significant part of their income), and value the freedom to set their own rates and choose their own projects. It works less well if you're early in your career, still building expertise, or require a guaranteed flow of income rather than an on-demand consulting model.
