More leads won't fix a leaking funnel

When the quarter looks short, every revenue leader reaches for the same lever: more demand. More spend, another SDR, a new list, a bigger event. The whole revenue industry is built to serve that reflex; there is always someone happy to sell you more pipeline.

Here's the uncomfortable question first: what happened to the last batch?

The arithmetic of pouring water into a leaking bucket

Run an illustrative number. Say a lead costs you $400 to generate, and your team fully works 60% of what comes in, which is a generous assumption for most sales-led portals. Your real cost per worked lead isn't $400; it's $667, because the unworked 40% paid full price to be ignored. Buy a thousand more leads and you haven't bought a thousand chances. You've bought six hundred chances and four hundred new residents for the dormant pile.

And it compounds. Attention is the constraint, not lead flow. The new leads arrive with urgency and push the aging ones further down the list, which means buying demand into an overloaded team doesn't just waste the unworked share of the new batch. It accelerates the abandonment of the old one. You paid to make your leak worse.

What recovery costs by comparison

The records already in your CRM (the unworked inbound, the stalled deals, the expired "not now"s) have an acquisition cost of zero. You already paid it. Recovering one costs the outreach: a rep's attention, a sequence of well-made touches, a system that knows which records deserve them. In most portals that is a fraction of what the equivalent new pipeline would cost to buy, and the buyers on the other end already know who you are.

None of this makes demand generation wrong. It makes sequencing wrong. Demand spend into a leaking funnel is buying at the top to lose in the middle; the same spend after the leak is measured and worked is what the spend was supposed to be all along.

The order of operations

First, measure the leak: how many owned records are sitting with commercial value attached and nobody working them, counted conservatively. Second, recover what's worth recovering; that's revenue this quarter from spend you made last year. Third, fix the mechanism that leaked it, so the funnel holds. Then buy more demand, with confidence, into a system that keeps what it catches.

If the measurement comes back small (a tight portal, disciplined follow-up, little to recover), buy the leads and don't look back. But that's a number you want to know, not assume. Most leaders who finally look are not comforted by what the filter returns.
