GLG

GLG is an expert-network firm, the kind of provider through which buyside investors pay for calls with industry experts. It appears as a tag on a May 2021 post by Matt Slotnick criticizing the expert-call industry: $1,500-an-hour conversations in which buyside people question “dubiously qualified but bored middle managers” and cannot sustain a dialogue beyond their script.
