The largest wealth transfer in history is underway — and it will change everything
The numbers are staggering. According to the Altrata World Ultra Wealth Report 2025, the global UHNWI population reached 510,810 individuals in mid-2025, with collective wealth of $59.8 trillion. By 2040, Gen X and Next Gens — millennials and Generation Z — will control 80% of that wealth. BCG and the Altagamma Foundation measured that millennials and Gen Z already accounted for nearly €200 billion in the luxury market in 2022, double the 2016 figure — with that number set to double again. The global luxury market stabilised at approximately €1.44 trillion in 2025, according to the Bain-Altagamma study — and the return to moderate growth expected in 2026 will be driven precisely by this new generation of clients.
This unprecedented wealth transfer is not merely about numbers. It is a revolution in expectations. Concierge services that have not anticipated this shift will find themselves perfectly calibrated for a clientele that is gradually disappearing.
Adopte une Conciergerie has structured its approach around this reality. Here is what we have understood — and what it means concretely.
Who is the ultra-wealthy Gen Z? Portrait of a client who is not who you think
Generation Z designates those born between 1997 and 2012. The oldest are 29 in 2026. A segment of them — heirs to family dynasties, founders of tech startups, content creators who have monetised audiences of tens of millions, or children of family offices who received an early endowment — already have access to significant wealth. The demographic profile shows that women represent 17.2% of Next Gen UHNWIs, versus only 12% across the overall UHNWI population — a strong signal about the evolution of this clientele.
What distinguishes this client from previous generations is not their money. It is how they spend it — and above all, how they decide.
1. Experience over possession
The ultra-wealthy Gen Z spends 15% more than other age groups in the luxury market, but its relationship with objects is fundamentally different. Travel & Hospitality is the leading spending category among younger HNWIs, far ahead of fashion or automobiles. According to the World Luxury Chamber, projected spending on travel and hospitality among UHNWIs averages $135,000, with the top 10% of spenders exceeding $770,000.
This is not inconsequential for a concierge service: this client does not want help booking a five-star palace. They want an experience they could not replicate alone, even with unlimited access to Google. The concierge becomes not an intermediary for booking, but an architect of uniqueness.
2. Authenticity as the primary selection criterion
According to Forbes and Revenue Management Labs research, 90% of Gen Z consumers will pay a premium for a brand they trust — but 81% have changed a purchase decision due to a brand's reputation or actions. Price is no longer a quality signal: it is a proxy for integrity. Gen Z evaluates whether a price is justified — by transparency, personalisation, ethics.
For a concierge, this means that hollow marketing claims — "five-star service", "exclusive access", "unrivalled network" — are perceived as noise. What persuades is concrete proof: a recommendation demonstrating intimate knowledge of the client, an address no one else could find, access that is visibly non-automatable.
3. Digital native but human first
An apparent paradox: the ultra-wealthy Gen Z is digital-first in their behaviours — discovering, comparing, deciding and sharing through digital channels — but they are more likely than any other generation to seek a high-value human interaction. McKinsey notes that aspirational Gen Z consumers are up to twice as likely to seek human styling advice than value-market shoppers. Digital is not a substitute for human: it is the filter that enables arriving at the human faster, and accepting only the best.
A concierge that responds only through chatbot or online form has already lost this client. But a concierge that takes 48 hours for a human response has also lost them. The winning equation: digital reactivity + human depth.
