The problem
Your message lives in ten places: website, LinkedIn, proposals, bios, decks. You update one and the other nine quietly drift. Prospects notice the mismatch before you do, and mismatched pages read as carelessness even when the work behind them is sharp.
The outcome
One source of truth for your message, and every page checked against it. Change the message once and you know exactly what else has to move. Everything you show the world stays consistent, because the consistency is the brand.
