Hey so I use GLG calls very regularly as part of my work
Not a scam at all
It’s a safe bet, just ask them to mask any personally identifiable information, and do not reveal anything that only you would know
Most experts end up only revealing metrics that are public, and I don’t necessarily expect to get insider information either. It’s more about learning stuff like - who are the users, how do they decide to buy the product, what GTM tactics ended up working, thoughts on white spaces that you see in the segment etc.
They pay really well for the calls :)
