$5,000 per hour

That's what one hour is worth to a Buyer with a $10,000,000 annual responsibility ($10,000,000 / 2,000 work hours per year.) That's $83.33 per minute. Cadence spammers steal half that with each hated email. Asking for a 15 minute "quick chat" is a request for a $1,250 spend.

When buying, ruling out an Apparently Inferior Option is at least two hours, or $10,000 in time value.

Engaging in a full cycle buying journey costs at least $50,000 in time. Because it takes on average five one-hour meetings, plus five hours administration, for the Buyer to qualify the Clearly Superior Alternative and decide to purchase it.
