One tool for enablement, customer education, and implementation handoffs, so context moves across the customer journey instead of being rebuilt at each stage.
The expensive loss in revenue teams is not effort, it is context. What was promised loosely, who the internal blocker is, why they bought at all: none of that fits in a CRM field, and it degrades every time it is retold.
Recording it once at the moment you have it means the next team watches before the call, and whoever inherits the account in month six gets the original rather than a summary of a summary.
Customer-facing walkthroughs are fine as public links. Handoffs contain pricing, contract terms and risk notes: keep those private to the workspace or grant them to specific people, with an expiry where the access is temporary.
