The world's most desirable brands spend decades building desire, then disappear at the exact moment a customer is most emotionally engaged. This is a three-month investigation into why, and what a PM would build to fix it.

🔍 This is a self-initiated research project. I have no affiliation with LVMH Group or any of the six brands studied. All six brands are real. All publicly available facts, founding dates, acquisition prices, revenue figures are cited from public sources. All performance metrics, NPS scores, repeat purchase rates, and financial projections are hypothetical scenarios constructed to illustrate the product argument. They are not actual company data. This document represents my independent analytical and product thinking, not reported outcomes.

📋 TL;DR - What this case study argues
LVMH Group operates 75 brands generating ~$86B in annual revenue. I spent three months studying the post-purchase experience across six of these brands, purchasing one item from each, documenting every communication received in the 30 days after delivery, and interviewing 36 luxury customers. The finding was consistent: in the 48 hours after a purchase arrives, the window of highest emotional customer engagement, every brand went completely silent. This case study diagnoses why that silence exists, quantifies the loyalty gap it creates using public data and hypothetical modelling, and proposes a three-module post-purchase platform called Après that would close it.

| What I did | Purchased one item from each of 6 LVMH brands. Documented all post-purchase communications in 30 days. Audited the digital post-purchase experience end to end. Interviewed 36 luxury customers across 4 segments. Built a hypothetical business case using public LVMH financial data. |
|---|---|
| What I found | Every brand went silent in the 48-hour window after delivery. No brand narrative. No product care guidance. No personalized re-engagement. The moment of highest emotional engagement was completely unmanaged. |
| What the data suggests | Using LVMH's publicly reported data and luxury industry benchmarks from McKinsey and Bain, I modelled the LTV gap created by post-purchase silence. The gap between current repeat purchase performance and luxury industry benchmark is meaningful and entirely addressable. |
| What I propose | Après (French for 'after'): a three-module post-purchase platform. Story (brand narrative at 48hrs after delivery) · Care (product maintenance intelligence at Day 7) · Return (personalized re-engagement at Day 14). Shared group infrastructure with fully sovereign brand experience layer. |
| What this is not | This is not a report of shipped outcomes. It is a structured product argument built on independent research, public data, and hypothetical modelling. No metrics reflect actual LVMH performance. |

💬 "I purchased a Dior fragrance and a Celine wallet in the same month. Both brands disappeared after the sale. The Dior fragrance arrived in beautiful packaging with a small card that said 'thank you for your purchase.' No story about the fragrance. No guidance on caring for a perfume. No invitation to explore the house's archive. A $280 fragrance from one of the world's most storied fashion houses, and the entire post-purchase relationship consisted of a shipping confirmation and a delivery notification."

I started asking other luxury customers whether they had experienced the same thing. The answer was universal. I decided to investigate it systematically, across six brands, over three months, with real purchases and structured customer research.

⚡ The research question: Is the post-purchase silence a deliberate brand choice, a capability gap, an organizational structure problem, or a measurement failure? And what would a PM build to close it?
</aside>
I chose to focus on LVMH brands for three reasons: LVMH is the world's largest luxury conglomerate making the multi-brand platform argument more coherent; all six brands operate e-commerce channels with publicly observable post-purchase flows; and the range across fashion, jewelry, watchmaking, and cosmetics let me test whether the silence was category-specific or universal.
| Brand | Founded | What I Purchased | Communications in 30 Days | What Was Missing |
|---|---|---|---|---|
| Christian Dior | 1946 | Sauvage EDP ($280) | Order confirmation, Shipping, Delivery. 1 promo email Day 22. Total: 4 | Zero brand storytelling. Zero care guidance. |
| Louis Vuitton | 1854 | Monogram canvas key holder ($280) | Order confirmation, Shipping, Delivery. Total: 3 | The world's most valuable luxury brand. Three transactional emails. Then silence. |
| Tiffany & Co. | 1837 | T wire bracelet ($375) | Order confirmation, Shipping, Delivery. 1-question NPS survey Day 8. Total: 4 | The NPS survey was the most substantive contact any brand made and it was one question. |
| TAG Heuer | 1860 | Aquaracer strap ($185) | Order confirmation, Shipping, Delivery. 1 promo email Day 28. Total: 4 | A brand whose entire value proposition is precision and craftsmanship sent zero content about either. |
| Celine | 1945 | Card holder ($350) | Order confirmation, Shipping, Delivery. Total: 3 | The fastest-growing LVMH fashion brand. Digital-native customer base. Most minimal experience of all six. |
| Givenchy | 1952 | L'Interdit EDP ($135) | Order confirmation, Shipping, Delivery. 1 promo email Day 18. Total: 4 | The house of the little black dress. Zero reference to heritage or product story. |

🚨 What every brand had in common: Not a single brand sent any content about the product the customer had just purchased. Every brand followed an identical pattern: order confirmation → shipping → delivery → silence → eventually, a generic promotional email. This was not a coincidence. It was a structural gap, the post-purchase window was not owned by anyone with a mandate to make it a customer experience.
