How do you ensure that product marketers you manage are creating great messaging, and hitting the right milestones?
When the customer nods in agreement with messaging, it's good. When they pull out a credit card or sign the contract, it's great.
Ultimately, a product marketer IC, leader, CMO, or CEO can opine on messaging all they want. None of it matters until it's put in front of a blunt customer or battle tested with dozens of prospects.
