Kretz Family Net Worth: a Careful 2026 Estimate Behind The Parisian Agency

Kretz family net worth: the short answer

The Kretz family net worth is not publicly confirmed. There is no audited document that breaks down the private wealth of Olivier, Sandrine, Martin, Valentin, Louis, and Raphaël Kretz, nor a public valuation of each family member’s stake in the agency. What is public is the business: Kretz Real Estate was founded in 2007, operates in luxury property, and became internationally recognizable through The Parisian Agency: Exclusive Properties on Netflix.

Our source-backed editorial view is cautious: a plausible family wealth range of about €20 million to €35 million, centered near €30 million. That range reflects the agency’s luxury positioning, media reach, and reported sales activity, but it should not be treated as an official net-worth disclosure.

A family business at the heart of luxury real estate

Before becoming television personalities, the Kretzes were first a family of real-estate professionals focused on high-end property. Kretz Real Estate operates in a market where discretion, trust, personal relationships, and access to rare properties matter as much as technical sales skills.

That family identity is part of the commercial proposition. Sellers of expensive homes want confidentiality and a strong network; international buyers want personal guidance. The Kretz brand combines family closeness, luxury codes, media storytelling, and a property network. That mix is why the family is often discussed not only as agents, but as a luxury real-estate brand.

What is publicly known about the Kretz business

Kretz Real Estate presents itself as a family-run luxury real-estate agency founded by Sandrine and Olivier Kretz in 2007. Netflix describes The Parisian Agency as a show following the family as they help clients buy and sell exceptional homes in France and abroad.

French press coverage adds useful business context. Capital and Europe 1 reported comments attributed to Martin Kretz that the agency completed around 100 sales in 2022, representing about €250 million in property value sold. Those numbers do not equal personal wealth, but they show the commercial scale the agency reached after the show increased its visibility.

Revenue, commissions, and wealth are different things

Many pages on this topic jump from sales volume to family fortune too quickly. The key calculation often quoted is simple:

That calculation is useful, but incomplete. Gross commission is not net profit, and net profit is not personal wealth. A luxury agency still has staff, marketing, taxes, office costs, commission-sharing arrangements, and possible co-broker splits. The right way to read the figure is as a signal of business scale, not a direct bank balance.

Why Netflix matters to the Kretz brand

Netflix did not create the agency, but it transformed its reach. ELLE notes that the show introduced the public to Sandrine, Olivier, and their four sons, while Capital and Europe 1 emphasize how the series helped attract sellers and buyers from outside the original Paris market.

For a luxury broker, brand trust is commercially valuable. It can help win more exclusive mandates, reassure international clients, and turn a local agency into a recognizable property brand. In a similar celebrity-and-assets context, our David Hallyday fortune profile also separates media value, family assets, and verifiable income.

Where the family’s wealth can come from

The Kretz family’s wealth may come from several connected sources:

• the value of Kretz Real Estate itself;
• commissions on high-end property transactions;
• the visibility created by TMC and Netflix;
• international mandates generated by the show’s reach;
• media, publishing, speaking, and partnership opportunities;
• brand extensions around luxury property and investment.

These factors support the idea of substantial wealth. They do not prove an exact amount for each family member.

A collaborative family approach

One of the Kretz family’s strongest assets is the way the family itself becomes part of the brand. Clients do not simply see an agency; they see a team built around trust, transmission, and complementary generations. In luxury real estate, that can be powerful because reputation and personal relationships often matter as much as the property listing.

Olivier and Sandrine represent the foundation of the company. Their sons bring different profiles: client relationships, development, strategy, media presence, international networking, and a modern understanding of communication. The family structure strengthens the story of the show and gives the agency a recognizable face.

International expansion and diversification

The market targeted by the Kretzes is not limited to Paris. The brand communicates around properties in France and a more international clientele. That matters for wealth estimates: the more an agency can position itself on rare and expensive homes, the higher its potential commissions can be.

Diversification may also include television visibility, books, events, private clubs, partnerships, and content around luxury property. None of these activities proves a precise fortune on its own, but together they strengthen the ecosystem around the Kretz name. That ecosystem, more than a single commission, explains why the family is often associated with substantial wealth.

Who is in the Kretz family?

The public family unit is Olivier Kretz, Sandrine Kretz, and their sons Martin, Valentin, Louis, and Raphaël. The show builds much of its appeal around that family dynamic: client relationships, property visits, negotiations, and internal conversations about the business.

That matters because the Kretz name is more than a brokerage label. It is also a media identity, and that identity helps support the business.

Olivier Kretz

Olivier Kretz is one of the founders and pillars of the agency. His public role is associated with experience, strategy, and the stability of the family company. In the Kretz brand image, he represents continuity and credibility.

Sandrine Kretz

Sandrine Kretz is also central to the story. She contributes to the family identity of the agency and to the image of a business where relationships, taste, and trust matter. Her role helps distinguish Kretz from a more anonymous luxury agency.

Martin Kretz

Martin Kretz is one of the most visible faces of the new generation. He is often cited in press coverage about the agency’s activity, including the reported 2022 sales figures. His media presence strengthens the link between the property business and the television exposure.

Valentin Kretz

Valentin Kretz contributes to the agency’s family-business dynamic. In the show, he helps illustrate the reality of the job: property visits, negotiations, client relations, and the balance between personal and professional life.

Louis Kretz

Louis Kretz also represents generational transmission. His presence shows that the agency is not only built around the founders, but around a broader family team able to carry the brand forward.

Raphaël Kretz

Raphaël Kretz, the youngest son in the public family image, completes the multi-generation story. His presence in the series supports the idea of a business designed as a family adventure over time.

Kretz Club

The Kretz Club shows the desire to extend the brand beyond a simple property transaction. A club or community around prestige real estate can create value through access to opportunities, investor networking, exclusivity, and long-term client relationships.

Still, caution is required. The existence of a club does not prove an exact fortune. It is better understood as a sign of diversification and brand elevation. In a net-worth estimate, this kind of initiative is a qualitative signal, not a hard accounting proof.

The Kretz family: origin, religion, and private life

Searches around the Kretz family often include origin, religion, spouses, divorce rumors, or private-life questions. Those topics may attract attention, but they need careful handling. Geneanet has published genealogical research on the family name and origins, but genealogy is not evidence of wealth.

Likewise, unsourced claims about religion, divorce, spouses, or individual fortunes should not be used as financial evidence. For this page, the reliable ground is the observable business: agency history, sales activity, commissions, media exposure, and brand expansion.

Origin of the Kretz name

The Kretz name is sometimes searched to understand the family’s background. That can be interesting historically, but it does not explain the current fortune. The family’s wealth should be linked to recent economic activity: luxury real estate, brand development, and media exposure.

Religion of the Kretz family

The family’s religion is a frequent search query, but it has no verified connection with the wealth estimate. Unless a reliable public source makes it relevant, this belongs to private life and should not be used to build a financial analysis.

Kretz family salary

There is no public salary table for each Kretz family member. Income may come from commissions, agency ownership, internal roles, media activity, or side projects. Here again, it is important to distinguish professional income, company profit, personal net worth, and brand value.

Our 2026 estimate

Taking into account the agency’s age, its luxury positioning, the reported 2022 sales figures, the Netflix effect, and the visible international brand, our cautious estimate remains:

Plausible family economic wealth: about €20 million to €35 million, with no official confirmation.

The often cited €29 million figure fits inside that range, but it should be read as a rough estimate rather than a verified fact. The Kretz family has probably built significant wealth through luxury real estate and media exposure; the exact family net worth remains private.

Bottom line

The Kretz family is a useful example of modern wealth built at the intersection of luxury real estate, television, and personal branding. The agency can generate large commissions, the show has strengthened international awareness, and the Kretz ecosystem appears broader than a conventional brokerage.

But caution remains essential. No public source certifies an exact family net worth. The best answer is therefore not a sensational number presented as certain, but a framed estimate: multi-million-euro wealth is plausible, with a cautious range of €20 million to €35 million, and €29 million as a frequently cited but unofficial order of magnitude.

Frequently asked questions

What is the Kretz family net worth?

Lama Fortune uses a cautious editorial range of roughly €20 million to €35 million for the family’s plausible economic wealth. It is not an official figure because the family has not published a consolidated personal net-worth statement.

Is the €29 million Kretz family fortune confirmed?

No. €29 million is best read as a media-style estimate within a plausible range, not as an audited or officially declared net worth.

Where does the Kretz family fortune come from?

It probably comes from a mix of luxury real-estate brokerage, commissions on high-value transactions, the value of the Kretz brand, media exposure from The Parisian Agency, and related international or luxury-property initiatives.

Where does the Kretz family live?

The family is strongly associated with Boulogne-Billancourt and the western Paris area in the show’s public image. Exact private-residence details should be treated carefully because they belong to private life.

Are the Kretzes Jewish?

This question concerns private life and is not useful for estimating the family’s wealth. Unless a reliable public source makes it relevant, Lama Fortune does not use it as part of the financial analysis.

How much does the Kretz agency make on a sale?

Press coverage often mentions commissions around 4%. On a luxury property, that can be a large amount, but gross commission still needs to cover splits, overhead, taxes, staff, and agency costs.

The most visible members are Olivier, Sandrine, Martin, Valentin, Louis, and Raphaël Kretz. The show also highlights the broader family dimension that forms part of the agency’s identity.

Which books or projects increased the family’s visibility?

The family’s visibility mainly comes from The Parisian Agency, but it may also be reinforced by public appearances, content, books, club projects, or luxury-property initiatives. These elements support the brand without proving an exact fortune.

Where can you follow the Kretz family?

You can follow their world through The Parisian Agency: Exclusive Properties, Netflix or TMC-related platforms, the Kretz Real Estate website, and the public channels of the agency or family members.
