"The fastest money in any business is sitting in the customers who already said yes. Most companies never go back for it."
Years ago at Prizeo, I sat in a leadership meeting and pitched two ideas that nearly got me run out of the room.
They were two low-touch, low-ticket additions that bookended the point of purchase: a small optional ask right as someone was checking out, and a second offer that landed right after they'd already bought. I put the revenue projections on the screen. I walked through the model. And the response, from almost everyone in that room, was that I had lost my mind.
The founding team pushed back. My fellow senior leaders pushed back. It went all the way down to the product manager and the customer-facing teams. The objection was always the same, and it was always delivered with total confidence: this will tank conversion. Customers will flee. You introduce friction at the worst possible moment, right when someone is about to pay, and they'll abandon the whole thing. One version of the feedback was, more or less, "Michael, this is a pipe dream. These numbers don't reflect reality." People were bracing for Armageddon.
I had a sliver of buy-in. The CEO, to his credit, eventually landed on "okay, fine, I trust you, go ahead." So we shipped it.
Conversion did not tank. There was no measurable effect. If there was a dip at all it was a rounding error, a percentage point at most, the kind of thing that disappears into the noise of a normal week. And average order value went up like someone had poured rocket fuel on it. The revenue came in almost exactly where my projection said it would. Down to the dollar.
I'm not telling you this to take a victory lap. I'm telling you because the interesting part isn't that I was right. The interesting part is that a room full of smart, experienced, senior people were so sure I was wrong. The money was right there. It was real, it was sitting in plain sight, and the people closest to the business were the most certain it didn't exist.
That gap is the whole subject of this piece. Because it's not a Prizeo thing. I've watched it happen at almost every company I've operated inside. The money hiding in your existing customers is usually the cheapest, fastest revenue available to you, and most companies never go back for it. The question I find genuinely interesting is why.
It's not because the money is hard to find. It's because going back for it asks something of you that's harder than analysis.
The first reason is that you literally can't see it.
Not because you're not smart. Because you're buried. When you're running a company, your attention is fully consumed by the thing in front of you: shipping the product, making payroll, putting out the fire that started this morning. Your bandwidth is spent, and spent attention has a strange side effect. It makes you blind to things that are right in your field of vision.
There's a famous experiment that captures this perfectly. In 1999, two researchers, Daniel Simons and Christopher Chabris, asked people to watch a short video of students passing basketballs and to count the number of passes made by the team in white shirts. It's a real task, it takes focus, you're tracking the ball. Partway through the video, a person in a full gorilla costume walks into the middle of the frame, stops, beats their chest, and walks off. They're on screen for nine seconds. When the researchers asked viewers afterward whether they'd noticed anything unusual, roughly half of them had no idea there'd been a gorilla at all. They were so locked onto counting passes that a person in an ape suit walked through the middle of the screen and they never saw it.
That's what running a company does to revenue that's sitting in plain sight. You're counting passes. The gorilla, the obvious, recurring money in your existing customer base, walks right through the frame, and you don't see it, because all of your attention is allocated somewhere else.
This is the honest reason an outside operator finds this stuff fast, and I'll just say it plainly because it's true: it's not that I'm smarter than the people running the company. It's that I'm not counting their passes. I walk in with my attention pointed at exactly one question. Where are customers already interacting with us, already saying yes, that we can lean into? I break the customer journey into its component parts and I look for the places where someone has already pulled out their wallet, because that's where the cheapest revenue lives. Fresh eyes aren't magic. They're just unallocated.
The second reason is fear, and it's the one nobody says out loud.
When a founder won't go back to ask a customer for more, it usually traces to one of two things, and often both. The first is that they're not anchored in their own value. Somewhere underneath the confident exterior is a quiet worry that the price is already a stretch, that customers are doing them a favor by paying at all, and that asking for more will expose the whole thing as overpriced. So the second ask never gets made, not because the customer would say no, but because the founder is afraid of what a no would mean about the value of what they've built.
The second is a quiet mistrust of the customer. The belief that the relationship is fragile, that customers are looking for a reason to leave, and that every additional ask is a withdrawal from an account that's already running low. So the company tiptoes. We can't push them. We have to walk on eggshells.
Both of these are scarcity talking. And here's what the eggshells crowd misses: in a healthy relationship, the second ask usually isn't a tax, it's a gift. The customer who just bought from you is, in that exact moment, the most engaged they will ever be. They've already decided you're worth it. Offering them something else they actually want, at the moment they're most receptive, isn't an imposition. It's service. The optional ask at checkout on Prizeo wasn't extracting something from people. It was giving people who clearly cared about the cause an easy way to do a little more. They took it, in droves, because we finally asked.
The third reason is that the customer-facing surface feels too precious to touch.
This one I have real sympathy for. The checkout flow, the moment of purchase, the post-sale experience, these feel sacred, because they're where the money actually changes hands. And so there's a deep reluctance to put anything there that might be clunky, or imperfect, or that might not work on the first try. Nobody wants to be the person who introduced friction into the one part of the business that's currently working.
But "it might be clunky" is not a reason to never test it. It's a reason to test it carefully. The unwillingness to run an experiment that might fail is, functionally, a decision to leave the money on the table forever. At Prizeo, the entire downside everyone feared, the conversion collapse, was a testable hypothesis. We could have argued about it in that conference room for another year. Instead we shipped it, watched the numbers, and had our answer in a couple of weeks. The fear was real. The risk, once you actually measured it, was almost nothing.
So those are the three: you can't see it because you're buried, you won't ask for it because you're afraid, and you won't test for it because it feels too precious to touch. Notice what all three have in common. None of them is analytical. Nobody in that Prizeo meeting had run the numbers and concluded the revenue wasn't there. They'd felt their way to "no." The money stays buried not because it's hard to find but because going back for it takes a kind of nerve most companies haven't built yet.
(There's actually a fourth reason, and it's the one structural exception to all this. It has to do with how companies organize themselves — almost everyone is built and incentivized around acquiring new customers, so nobody actually owns the job of going back to the existing ones. That one's worth its own discussion, and I get into it in "Acquisition is the expensive way to grow.")
Here's what I'd do with this, if you're a founder reading it.
This week, before you spend another dollar trying to find a new customer, go look at the customers you already have. Map the places where someone has already said yes to you, the moment of purchase, the renewal, the first successful outcome, and then ask yourself an honest question at each one: have I ever gone back and asked for more here? Not in a way that takes from them. In a way that offers them the next thing they'd actually want.
Most companies, when they do this exercise honestly, find a gorilla in the frame. The money was never hidden. They were just counting passes.
Ask once and you've built a transaction. Ask again, at the right moment, in the right way, and you've started building something worth a lot more than that. The customers who already said yes are telling you something. Most companies just never go back to listen.
