What buyer win-loss interviews reveal about the sales execution gap

Your sellers know the product. They’ve done the learning. They can recite the value prop. Yet they’re still losing deals they should win.

That’s the execution gap — and it’s one of the most expensive problems in sales. Without connected systems, even strong sellers lose deals to operational chaos. Up to 30% of revenue potential is lost to inconsistent execution across the revenue team. Not because the strategy was wrong, but because the moment the seller was in didn’t match the playbook they were given.

Most revenue teams try to diagnose that problem internally — reviewing CRM data, replaying call recordings, running pipeline analysis. But the one perspective that would change the picture most is the one they rarely hear: the buyer’s.

We sat down with Spencer Dent, co-founder and co-CEO of Clozd — a win-loss analysis platform and service that interviews buyers to uncover the real reasons deals are won, lost, or stalled. After thousands of those conversations, Spencer has a view of the execution gap that most revenue leaders never get: what it looks like from the other side of the table.

What most revenue teams get wrong

Q: You hear from buyers after every deal. What’s the most common gap between what the revenue team believes happened and what the buyer says actually happened?

Spencer: The biggest gap is often much simpler than people expect: Companies think they know why they won or lost a deal, but they usually don’t.

Every one of our longest-tenured customers has a story about winning back a deal they thought was dead. In some cases, a single win-back has paid for their entire win-loss program. Those opportunities were always there — they just didn’t see them.

The specific blind spots vary from company to company. Sometimes the issue is product-market fit. Sometimes it’s sales execution. Sometimes buyers couldn’t clearly see the business value or ROI. But there’s almost always a gap between what the company believes happened and what their buyers say actually happened.

One of the reasons is that internal systems aren’t nearly as reliable as most organizations assume. In our research, roughly 85% of CRM loss reasons don’t match what buyers tell us actually drove their decision. Sellers are required to log a loss reason even when they don’t really know it, so they make their best guess.

There’s another layer to it. Buyers don’t tell sales reps everything they’re thinking. They have internal debates, executive conversations, and discussions with competitors that never make it into the sales process. When we compare buyer interviews with call recordings, we find that 77% of the factors that ultimately influenced the decision never came up during the sales conversations.

That’s why independent buyer feedback is so valuable — you’re uncovering the parts of the buying journey your team never had visibility into.

Confidence vs. regret in deal outcomes

Q: Across the buyer interviews you and your team at Clozd have conducted, what separates the deals where the buyer felt confident in their decision from the ones where they had regret or hesitation?

Spencer: The confident decisions almost always start with deep discovery.

Buyers consistently tell us they felt understood. The seller took the time to understand their business, asked thoughtful questions, and focused on solving the right problem instead of rushing into a product pitch.

They connect their capabilities to the customer’s specific priorities, reinforce those claims with relevant customer stories, and provide the case studies, references, and proof points buyers need to build internal consensus. By the time a confident buyer signs the contract, they know how they’re going to champion that decision inside their own organization.

Feedback without follow-through

Q: Most revenue organizations say they want to hear from their buyers. But when they actually do, what’s the most common reaction, and how often does it lead to action?

Spencer: It really comes down to culture and sharing the insights with the right people.

Organizations with strong executive sponsorship tend to embrace customer feedback — even when it’s uncomfortable. They see it as an opportunity to improve rather than something to defend against.

Others struggle. They don’t share the insights broadly, the data is siloed or filed away, and very little changes. That’s one of the most frustrating things we see, because the real value of win-loss feedback comes through acting on it, not just collecting it.

One of our longest-tenured customers, Avalara, has been running a win-loss program with us for nearly eight years. They attribute much of their success to what they call “the humility of our culture and the willingness to hear hard things and act on them.”

That’s exactly the mindset that turns customer feedback into competitive advantage.

The biggest misconception about buyers

Q: What’s one assumption organizations consistently make about their buyers that your data proves wrong?

Spencer: That wins and losses are permanent.

CRM systems tend to treat every opportunity as final — won or lost — but buyers don’t think that way. We’ve found that around 10% of closed-won customers are already at risk by the time we interview them. They’re experiencing implementation challenges or questioning whether they chose the right solution. If nobody uncovers those concerns early, they often resurface at renewal.

The opposite is true for many lost deals.

Depending on the company, we’ve seen as many as 40% of closed-lost opportunities remain viable. Maybe the evaluation was paused or the competitor didn’t work out. Maybe the customer simply wasn’t ready to move forward.

The point is that buyers rarely see these decisions as permanent — and neither should you.

Where preparation meets execution

Q: A lot of AI investment in sales is going toward preparation — research, talking points, content suggestions. But execution happens live, in the room, under pressure. From what buyers tell you, is better preparation actually translating to better meetings?

Spencer: Sometimes. The best salespeople are using AI to eliminate administrative work so they can spend more time preparing thoughtfully for customer conversations. When that happens, buyers notice.

But we’ve also started hearing that more buyers describe meetings as polished but impersonal. The rep knows the company, has read the annual report, and covers all the right talking points — but when the conversation shifts or the buyer raises an unexpected concern, they struggle to adapt.

AI can absolutely make sellers more prepared, but it can’t replace curiosity, active listening, or the ability to have a meaningful conversation.

The best sales conversations still happen in the moment, and the seller’s skills determine what happens next.

The execution gap buyers see — and you don’t

A thread runs through everything Spencer describes — from “polished but impersonal” meetings to buyers who regret choosing the seller who rushed past discovery. The knowledge was there. But the way they executed didn’t fit the room they were in.

A medical device rep who knows the clinical evidence but can’t navigate four new members of the value analysis committee. A building materials seller with the right spec sheet who can’t adapt when priorities shifted overnight because of a tariff change. A beverage rep who prepared for the meeting they expected — not the one they showed up to.

That’s the execution gap most organizations can’t track — because they focused on communicating the strategy, not checking whether it was actionable in the field. The buyers from Clozd interviews see it clearly. The question is whether your team is set up to hear it.
