Most founders have two of these working against them:
Clarity
Do prospects immediately understand your core value, or are you spending the first ten minutes of every meeting clearing up confusion?
Differentiation
If you stripped the logos off your site and your closest competitor's, could a buyer actually tell the difference?
Audience Fit
Is your story accidentally optimised for technical peers instead of the economic buyers who control the budget?
Commercial Intent
Do investors and prospects call your idea fascinating, then disappear when it's time to sign or commit funds?
Consistency
Is your sales team, your marketing, and your product team all describing your company differently?
