There is a number every B2B revenue leader should know about their installed base and almost none do.

The number is: how many of the people who bought, championed, or used your product in the last 24 months are still in the same role at the same company.

For most companies, the answer is around 70%. Which means about 30% of your customer champions are somewhere else right now. Different company. Different role. Same problem to solve. Same predisposition to buy your category. Probably with budget.

That cohort of people is the highest-conversion outbound list you will ever have, and most companies have it sitting in their CRM as stale contact records that bounce when the BDR tries to email them.

This is what champion mobility costs you when you don't track it. It is also one of the most fixable problems in modern GTM, because the data exists, the motion is well-understood, and the math is exceptional. Here is the thesis, the evidence, and the playbook.

What is champion mobility?

Champion mobility is the rate at which the humans who matter to your business (buyers, users, internal advocates) change jobs, roles, or companies over time.

The cohort of "humans who matter" is bigger than most teams think. It includes:

• The buyers who signed the contract.
• The technical champions who internally advocated for you.
• The end users who actually loved the product.
• The buying-committee members who were nominally part of the decision.
• The customer success counterparts at the customer.
• The procurement and finance contacts (yes, even them).

Each of these humans, when they move, generates a signal. The signals are individually small and collectively enormous.

A typical 200-employee B2B company with 500 active customer relationships will see roughly 750-1500 humans change jobs across that customer base every year. If even 30% of those moves are to other companies inside your ICP, that is 225-450 warm pipeline opportunities a year. That you didn't have to pay for. That convert at multiples of cold.

Almost no one captures this systematically. The data is right there. The instrumentation isn't.

The Narvar number

We talk about Narvar's $17 million in champion-mobility pipeline because it is a concrete example, not because it is unusual.

Narvar is a post-purchase experience platform serving retail and e-commerce. Their installed base is exactly the kind of customer cohort where champions move regularly: digital, marketing, and e-commerce operators who change jobs every 2-3 years and tend to bring their tooling preferences with them.

What Narvar did:

1. Identified, across their installed base, the humans who had advocated for, championed, or extensively used the product.
2. Instrumented job-change detection on that cohort so they got notified within days when someone moved.
3. Triggered a warm-intro motion the moment the move was detected, before the new employer had a chance to build a competitive RFP.
4. Routed the intro through the original Narvar relationship (the customer success counterpart, the original AE, or the original technical contact), so the outreach came from someone the champion already trusted.

Outcome: $17 million in pipeline in one year, from people who already loved them, landing at new companies that already needed them.

The interesting question is not "how did Narvar get this number." The interesting question is why most companies, with similar installed bases, get a number near zero.

The answer is operational, not strategic. Almost every revenue team agrees champion mobility is valuable in principle. Almost none have built the four operational pieces (cohort definition, mobility detection, intro routing, attribution) to capture it.

Why this works better than almost any other outbound motion

Three reasons, in increasing order of importance.

One. The relationship is pre-warm. When a champion moves to a new company and you reach out, the reply rate is not the 1-3% of cold outbound. It is 60-80%. The champion already knows you. They liked working with you. The bar to a first meeting is "are you free Tuesday."

Two. The buying need usually exists at the new company. People bring their tooling preferences with them. A VP of Marketing who loved your product at Company A and just landed at Company B is, statistically, going to bring up your product within their first 90 days. The only question is whether you reach out first or whether they have to remember to email you.

Three. The competitive dynamic is fundamentally different. When a champion lands at a new company, your competitor doesn't know the move happened. You do. You have a 30-90 day window where the buying decision can be steered by an inside advocate before any RFP gets written. That window closes fast. Most categories' competitive races are won or lost in those 90 days, not in the formal procurement.

The combination of pre-warm relationship, latent demand, and competitive timing is what makes champion-mobility pipeline the highest-quality outbound channel that exists for most B2B companies.

Why most companies don't capture it

Five reasons, each fixable.

One. Job-change detection is unreliable in CRMs. Salesforce contact records do not auto-update when someone moves. The contact's email bounces, the name stays, and the record gets quietly stale. Most CRMs don't fire any signal at all when a contact changes companies. The change goes invisible.

Two. The cohort is undefined. Who counts as a "champion" worth tracking? Most teams don't have an explicit definition. Without a definition, the data team can't filter the cohort, and the GTM team can't act on it.

Three. The intro motion is unowned. When a champion does move, whose job is it to reach out? The original AE? The CSM? Customer marketing? Most companies don't decide, so nobody does it, so the moment passes.

Four. The attribution is fuzzy. When pipeline does come in from a champion who moved, it shows up as "inbound from existing contact" or just "new opportunity." The fact that it came from a tracked champion mobility event is rarely captured. So no one can build a business case to invest more in the motion.

Five. The motion looks small until you do the math. A single champion move generates one opportunity. The instinct is "that's nice, not worth building a program for." The actual math, across 500 champions and 25% mobility, is in the hundreds of opportunities and millions in pipeline a year. The unit economics only look right at scale, and you only see the scale once you've instrumented it.

The playbook

Six moves. None of them are conceptual. All of them require an explicit owner.

1. Define your champion cohort

Write down, in clear criteria, who counts as a champion worth tracking when they move. The pattern that works:

• Anyone who signed or renewed a contract.
• Anyone who was the primary internal advocate during the original sales cycle (look at deal records).
• Anyone with a NPS score above 8 who used the product weekly for 6+ months.
• Anyone who served as a reference, spoke at a customer event, or appeared in a case study.
• Anyone who logged 50+ hours of product usage and was identified by their CSM as a power user.

Cast wide. The cohort can be 2,000-10,000 humans for a mid-market company. The economics work because mobility detection and intro drafting are cheap once instrumented.

2. Instrument job-change detection

This is the technical step most teams skip. You need a system that, for every human in your cohort, monitors LinkedIn, email signatures, public web mentions, and (if possible) verified third-party data, and fires a signal within days of a real job change.

Off-the-shelf tools (Boomerang, Connect The Dots, The Swarm, and others) do this. You can also build a basic version in-house against LinkedIn data plus periodic email validation. The point is to know within days, not within quarters.

3. Route the intro through the original relationship

When a move is detected, the outreach should come from the human at your company who knew the champion best, not from a generic BDR.

The pattern:

"Hey Jamie, just saw you moved to Glossier as VP CX. Congrats. We loved working with you at Sephora. If it's helpful as you ramp up, happy to share what worked at Sephora and would love to introduce you to the team here. No pressure."

This is a 60-second email. It works because the relationship pre-exists. It does not work if a stranger sends it. The routing is the entire game.

4. Build a 90-day playbook around the move

Most champions don't make buying decisions in their first week at a new role. They make them in their first 60-90 days, after they've assessed the existing stack and identified what's broken.

Your motion should map to that window:

• Days 0-14: Congratulations, light touch, share helpful resources from their previous work with you.
• Days 15-45: Open a thread about what they're building at the new company, ask if they want to share notes on what worked at the previous one.
• Days 46-90: Move toward a clear conversation about whether your product fits the new environment.

Most teams either rush this (a sales pitch in week 1, which kills the relationship) or miss it entirely (no contact until 6 months later, by which point the buying decision has been made).

5. Tag and attribute every opportunity

Every opportunity that comes from a tracked champion mobility event should be tagged in your CRM with a specific source: "champion mobility / customer X / champion Y / move detected Z."

This is the only way you'll build a defensible business case for the program. After 12 months, you should be able to pull a single report that shows: X champions moved, Y opportunities generated, Z pipeline created, W revenue closed, all attributed cleanly.

6. Make a single human own it

The biggest reason most champion-mobility programs fail is that the work falls between functions. The CSM thinks it's the AE's job. The AE thinks it's customer marketing's job. Customer marketing thinks it's the sales development team's job. So no one does it.

Pick one person. It can be a customer marketing lead, a customer-led-growth manager, a revenue operations specialist. The title matters less than the explicit ownership. They run the program. They report on it monthly. They are accountable for the pipeline number.

The thesis

Most companies' installed bases are quietly the largest underused pipeline source they have.

The math: 25-30% of your champions change jobs each year. Half of those moves are to ICP companies. The conversion rate from "tracked move + warm reach-out" to first meeting is 60-80%. The conversion from first meeting to opportunity is well above your average outbound. The competitive timing window is 30-90 days from the move.

Multiply that out for any installed base above 200 customers and you get a pipeline number in the seven figures, easily. For installed bases above 1000, you get the Narvar number. For installed bases above 10,000, you get a number that is competitive with your entire outbound program.

The reason almost no one captures this is operational, not strategic. The technology to detect moves exists. The motion to route the intro works. The math is straightforward.

The companies who instrument this in the next 18 months are going to have a structurally cheaper, higher-quality pipeline channel than companies who don't, and the gap will compound.
