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.

Frequently Asked Questions

What is the main difference between GLG and Catalant?
GLG is a research platform for expert calls — you get 30–60 minute access to industry veterans to extract knowledge. Catalant is a consulting marketplace — you hire ex-MBB consultants to execute strategy projects over weeks or months. GLG = knowledge; Catalant = deliverables.
Can a startup use GLG or Catalant?
Startups can use Catalant with a scoped project budget. GLG's annual enterprise contracts ($50K+ minimum) make it impractical for most startups. For primary research needs, startups are better served by Catalant one-off advisory calls or alternative expert network options with lower entry points.
Do institutional investors use GLG or Catalant more?
GLG dominates for institutional investor use cases, particularly PE and hedge fund due diligence. The MNPI compliance infrastructure is essential for regulated investment activity. Catalant is used more by corporate strategy teams and consultancies that need project execution rather than primary research calls.
Are GLG and Catalant competitors or complementary?
Primarily complementary. Many institutional teams use GLG for the research phase (expert calls to gather market intelligence) and then hire via Catalant for the execution phase (building the strategy based on that intelligence). The workflows are different enough that using both makes sense for complex initiatives.
How does GLG compare to Catalant on expert quality?
Different dimensions. GLG's quality is breadth — 1M+ experts with compliance screening, best for finding someone who held a specific role in a specific industry at a specific time. Catalant's quality is depth — a smaller network of ex-MBB consultants who are expert at structured problem-solving and project delivery. GLG wins on scale; Catalant wins on strategy execution pedigree.
