Applications in sales and customer experience

Mapping the journey to identify peak and end

Before orchestrating a peak and an end, you must map the customer journey. It's the most overlooked step — and the most profitable.

The 4-step method

1. List every touchpoint between your prospect/customer and you (from the first email to the last post-purchase interaction).
2. Rate the emotional intensity of each touchpoint on a scale from -5 (very negative) to +5 (very positive).
3. Identify the current peak (point of maximum intensity) and the current end (last contact).
4. Audit: are these two points intentional? Intense enough? Distinctive?

Mapping example: a B2B SaaS funnel

Diagnostic: the peak is an unintentional in-app success (so uneven across customers), and the end is a plain renewal email. This journey massively under-leverages the peak-end rule.

Designing a peak moment in sales

The 5 levers of a memorable peak

According to the Heath brothers (The Power of Moments, 2017), a peak moment combines at least one of these levers:

Concrete example: the B2B demo

Standard demo (intensity: +2)

• The sales rep shows the features
• Asks discovery questions
• Proposes a trial

Peak-end optimized demo (intensity: +5 at peak, +4 at end)

• Peak (insight + elevation): before the demo, the rep spent 30 minutes analyzing public data on the prospect's company. He starts with: "I estimated that your churn costs roughly €280K/year in lost CLV. Here's how our tool would have flagged 6 of your last 12 churn cases. Let's look at your data."
• End (connection): he ends by sending a personalized 3-minute Loom recapping the 3 key points discussed and a scanned handwritten note: "Regardless of your decision on our tool, here's an audit you can use freely. Talk soon, [Name]."

Typical result: conversion rate 2x to 3x higher than the standard demo, and lasting memorability even if the prospect doesn't sign immediately.

Designing the end: never let the customer exit on a neutral note

The end is the most overlooked lever in business — and the most profitable, because it conditions:

• The probability of recommendation (NPS)
• The probability of repurchase or renewal
• The probability of a spontaneous testimonial

The 4 critical endings in business

The principle: turn each ending into a doorway

A successful ending isn't a closure, it's an open door to the next cycle:

A demo that ends with a useful gift creates more pipeline than a demo that ends with a forced close.

Use cases: SaaS, agency, and trainer

In B2B SaaS

• Peak: "Time to First Value" feature in less than 5 minutes after signup, with a dynamic message celebrating the moment ("You just analyzed your first dataset — here's what we detected for you")
• End: renewal email co-signed by the founder, with a personalized ROI recap of the past year

In freelance agency

• Peak: surprise deliverable not in the quote (e.g., a bonus mini SEO report on top of the website redesign)
• End: one month after the mission ends, send a "how is it going?" email with a free 15-minute check-in

In training / coaching

• Peak: live "breakthrough" session mid-program where you help each participant unlock their personal problem
• End: certification ceremony with pre-formatted LinkedIn share + optional filmed testimonial

Handling negative peaks: an anti-pattern to neutralize

Every journey potentially contains negative peaks — moments when the customer feels intense frustration. If you let them stay without intervention, they become the memorized peak.

Frequent sources of negative peaks

The golden rule: recovering a negative peak creates a positive peak

This is the service paradox: a customer who experienced a problem well-handled is often more loyal than a customer who never had a problem. The transformed negative peak becomes a more intense positive peak than spontaneous positive peaks.

A well-handled problem isn't a loss. It's an opportunity to create a memorable peak.

Summary

The peak-end rule transforms customer experience strategy: instead of aiming for costly uniform quality, you invest asymmetrically on two moments — the peak and the end. The method runs through honest mapping of the journey, identifying default peaks and ends, then intentionally optimizing them. The levers (elevation, insight, pride, connection, distinction) help you design memorable moments. The end must always be positive and distinctive, never neutral. Well-recovered negative peaks become even more powerful positive peaks. In the next chapter, we'll see how AI lets you industrialize this approach at scale.
