The Bottom Line
GLG is the broadest platform in the expert network space. With ~1.2 million experts, multi-format research (calls, surveys, events, library, placements), and deep compliance infrastructure, GLG is the default for large institutions that need scale and breadth across every sector. The trade-off is cost — GLG is typically the most expensive option — and the platform's breadth can overwhelm teams with simpler needs.
Third Bridge differentiates through content. Its Library (formerly Forum — pre-published interview transcripts covering 65,000+ companies) and Connections product give research teams asynchronous access to expert insights without scheduling calls. For buy-side investors who want to scan industries quickly before committing to live consultations, Third Bridge's library-first model is distinctive. Third Bridge claims 1.5M+ experts — comparable to GLG's ~1.2M — but with a narrower service scope focused on content and calls rather than GLG's multi-format breadth.
Teams that prioritize breadth, scale, and multi-format research lean toward GLG. Teams that value pre-built content libraries and efficient desk research lean toward Third Bridge. Many institutional investors use both.
