The Bottom Line
GLG is the industry's broadest platform. If you need multi-format research (calls + surveys + events + library + placements), global coverage across nearly every sector, and the most established compliance infrastructure in the space, GLG is the default choice for large institutional buyers. The trade-off: it's typically the most expensive option, and the breadth of the platform can feel heavy for teams that just need fast expert calls.
AlphaSights positions itself as the speed and service leader. If your team operates under time pressure (PE deal diligence, fast-moving hedge fund research), AlphaSights' custom-sourcing model and high-touch project management are a core part of their value proposition. Their AI investment (AlphaGPT, AlphaGraph) is aggressive, and the firm has maintained a 70% CAGR since founding. The trade-off: narrower product suite than GLG, and the per-call pricing model can add up for high-volume users.
Some research teams use both — GLG for breadth and AlphaSights for speed. They're complementary more than they are substitutes.
