Finally chased down a prospect (let's call him Mr. D) who'd asked us for a fair amount of upfront analysis (my mistake) to see if our data would work for his purposes (after which he'd promptly disappeared for five months). We chatted amiably, weather and business and such. He explained that they'd gone ahead and done the work themselves, but might like to use our data now to corroborate their findings.
"Great!" I said. "Can you send us your findings?"
Unfortunately, no, he couldn't, he had to check with somebody else internally who "owned" the data.
"Great!" I said. "So you'll check with her, then send us the data?"
"Yes," he said. And paused. And continued: "But if you don't hear from us, that means we're not interested."
Um... OK, Mr. D. Thanks for the call.
And thanks, too, for the reminder of what always comes from giving away work for (here comes the F-word) free: Not a sale, not gratitude, not even common courtesy (would it be so hard to send an email saying, "No, thanks?") Just expectation of more free stuff.
If you don't hear from us again, Mr. D., that means that we're not interested, either.
