Your sales team isn't the problem. The leadership gap is.
You have a VP of Sales running plays. You need a CRO running the system. The difference shows up in your forecast accuracy, your board conversations, and your bank account. The average VP of Sales lasts 18 months - not because they lack talent, but because they were trained on systems built for a buyer who no longer exists, then asked to hit modern targets with outdated physics.
Engagements start with a 3-6 month foundation phase. Not as an advisor on the side - as the person accountable for the revenue number.
If I'm wrong about your situation - if this is a product problem or a market problem instead of a revenue leadership problem - I'll tell you in the first 15 minutes. No deck. No demo. A conversation between two people who take revenue seriously.
