Why Do Deals Fall Apart when the Champion Leaves?
A single-threaded deal rests on one relationship inside the buyer's company, and single-threaded deal risk is what that exposes you to. The reasons for the purchase live in that one person's head. When they leave, the company loses the reasons with them, and whoever is left has nothing to act on.
A resignation email goes out inside the customer's company, and a deal you had forecast for this quarter stops moving.
What Did the Champion Hold That Nobody Else Did?
Your champion held the memory of the deal. Why the problem mattered, what it was costing, which objections had already been answered, who had agreed to what, and their working relationship with you.
James Walsh and Gerardo Ungson, in a 1991 paper in the Academy of Management Review, described the places an organization stores what it knows. Individuals, culture, procedures, roles and structures, the physical workplace, and outside records. A case that has only been argued in meetings and carried by one person is stored in the first place on that list, the individual. Knowledge held by one person leaves the company when that person does.
The deal has a written record in your CRM. Inside the buyer's company, the case may exist only in what the champion remembers.
Why Do Sellers Keep Building Single-Threaded Deals?
The case for building on one relationship is real. It is faster. It is what a rep can build in the time a sales cycle allows. The champion may prefer it, because owning the vendor relationship gives them standing inside their company.
He Peng, in a 2013 survey of 190 knowledge workers in China, found that people who felt a piece of knowledge was their own were more likely to hide it from colleagues, and that territorial feelings carried the effect. The link held for people who felt little ownership of their organization and disappeared for people who felt the organization was theirs too.
A champion who treats what they know about the deal as their own, and feels little ownership of their company, may be more likely to keep the case to themselves.
The cost shows up later. A second relationship takes weeks to build, and a departure can come with a few days' notice, so there may not be time to build one once the champion gives notice.
The champion's preference is the part worth working with. A champion who wants to own the relationship may agree to share the case once it is framed around their own risk. A project that only they can explain stalls when they take a vacation, get promoted, or get pulled onto something urgent. A second person who knows the case keeps their project moving while they are away, and that is a reason they can say yes to.
What Does the Company Remember after the Champion Leaves?
After the champion leaves, the company remembers what was written down, what sits in a shared system, and what a second person can explain.
Marina Fiedler and Isabell Welpe, in a 2010 study of how organizations remember, found that writing things down and sharing them electronically moved knowledge out of individuals and into the organization's other stores. For your deal, that means a business case saved where a successor would find it, and at least one more person inside who has heard it and can repeat it.
Nataliya Galan's 2023 review of research on knowledge lost to turnover found that knowledge held in people's experience and relationships is harder to replace than written knowledge. Much of what a champion knows about your deal is that kind.
Is a Single-Threaded Customer Account a Churn Risk?
Yes. The same thing happens after the signature, on a longer timeline.
A customer account with one active contact has one person who remembers why the company bought, what it replaced, and what it has delivered since. When that person leaves, the renewal gets decided by people who never heard the case and see only a line item. The product may be in daily use, and the account can still be lost, because nobody left can explain what it does for the business.
Joseph Broschak tracked advertising agencies and their clients from 1986 to 1998 for a 2004 study in Administrative Science Quarterly. When managers left the client companies, the agency relationships became more likely to end, and the size of the effect depended on the size of the firm. These were ongoing service relationships, the position a customer account is in after the signature.
From the CSM's seat, it looks like every email thread going to the same address, every QBR attended by the same person, and a health score that stays green because that one person logs in. That account belongs on the risk list, whatever the score says.
What Do Deals That Survive a Departure Have in Common?
They were built so the company could remember them. The case was written in the buyer's language and tied to a metric the department tracks, whoever holds the job. The value was counted in that department's own numbers.
At least two people inside could explain the case, and one of them sat above the champion. And the seller treated a departure as an ordinary event, with a plan for the successor conversation ready before anyone gave notice.
Which of My Deals Would Survive a Departure Today?
Run three questions on each open deal.
- Is the business case written down in the buyer's own words, somewhere a successor would find it?
- Could a second person inside the account explain the case well enough to defend it?
- Has anyone above the champion heard the case from you directly?
Each no is a gap to close before the champion's next job change, and the forecast won't show you which deals have them.
For each deal with a no on question two, ask your champion this week to walk one named colleague through the case.
