Platform Overview
GLG (Gerson Lehrman Group)
GLG is the market leader in expert networks — a category it largely invented. Founded in 1998, the platform connects institutional buyers (PE firms, hedge funds, management consultancies, and corporate strategy teams) to its network of 1M+ practitioners, former executives, academics, and regulators. The core product is the expert call: a structured 30–60 minute session where the client asks questions and the expert answers based on domain experience.
GLG's compliance infrastructure is a key differentiator for investment contexts. The platform screens for material non-public information (MNPI), manages wall-crossing protocols, and provides audit trails required by regulated financial institutions. This compliance layer is why GLG remains dominant in PE/VC due diligence despite competition from newer entrants.
Catalant
Catalant (formerly HourlyNerd, founded 2013) is a consulting talent marketplace built around ex-MBB independent consultants. The fundamental pitch: get McKinsey-quality strategy work at boutique prices, by accessing former McKinsey principals working independently. The platform moved upmarket over time and now serves primarily Fortune 500 companies and growth-stage firms with complex strategy needs.
Unlike GLG, Catalant experts deliver work product — strategy decks, market analyses, integration plans, organizational assessments. The engagement isn't a call; it's a project with deliverables, milestones, and a defined scope. This execution orientation is what differentiates it from research-focused platforms.

Vetting Approach
How GLG vets experts
GLG's vetting is compliance-first, not skill-first. Before joining the network, experts verify their credentials, employment history, and confirm they are not in possession of MNPI that would make consulting illegal. The platform runs ongoing MNPI screening and requires experts to complete compliance training. For investment research use cases, this compliance infrastructure is more important than any skill assessment.
How Catalant vets consultants
Catalant's vetting centers on credentials and track record: confirmed ex-MBB or top strategy firm employment, verification of specific projects and outcomes, and an initial platform orientation. Catalant also facilitates client reviews and builds consultant reputations over time. The implicit quality signal is the pedigree — a former McKinsey Engagement Manager who worked there for 5 years carries a built-in baseline of capability. That said, there is no live problem-solving assessment like Toptal's.
