I've found that sometimes the existing gap in the team could be positioning, messaging, or just a basic onboarding process--you would expect those things to disappear around a Series A raise but it's just wishful thinking in my experience and companies are not vacuums.
Finding a solid performance marketer is probably easier than nailing those things. To your point, if you've got traction, deep expertise, and the foundation for marketing set then performance is the focus next. Appreciate the B2B perspective!
