VERDICT

Should I use Glg?

Leading Expert Network for Trusted Human Expertise - glg.it

Depends. Buy if you're a consultancy, investment fund, or enterprise needing vetted expert calls and can absorb $25K–$300K+ annual commitments. Skip it if you're a small team or individual — opaque credit pricing and a 2023 data breach make lighter pay-per-call networks smarter.

Confidence

Medium. Based on ~20 public sources: customer and employee reviews, pricing analyses, breach notifications, and GLG's own site. URL pasted (glg.it) had no separate security page; evidence maps to GLG (Gerson Lehrman Group).
