The Kretz family’s net worth is estimated at €30 million in 2026. The stars of The Parisian Agency: Exclusive Properties have turned spectacular home tours, family arguments and the sound of a closing gong into a luxury real estate brand with international reach. Behind the Netflix success are Olivier and Sandrine Kretz and their four sons, building a business that began long before the cameras arrived.
Their latest chapter is bigger than another glamorous listing. A new Paris flagship, an overseas franchise program and Kretz Club are extending the family’s influence beyond the houses they sell. More than €500 million in customer property transactions was reported for 2025. Those homes belong to the clients; the Kretzes earn brokerage fees and build value in the business that brings buyers and sellers together.

Kretz family net worth: a €30 million family success story
The €30 million estimate is the family’s combined wealth, expressed in euros. It reflects the careers and business interests of the parents and their four sons together. Their rise brings together nearly two decades of property brokerage, the value of a recognizable brand and assets accumulated along the way.
For US viewers discovering the family through Netflix, the appeal is immediate: remarkable French homes, demanding clients and relatives who cannot quite leave work at the office. For a seller, that same familiarity has a commercial purpose. A homeowner considering an agent may already recognize Martin’s approach to a negotiation or Sandrine’s eye for a room.
That connection gives the Kretzes a memorable introduction to potential clients. The next step is still intensely practical: secure a listing, present it well, find the right buyer and close the sale. Their family fortune grows around that repeatable business, with television giving the agency a much larger audience.

Olivier and Sandrine Kretz: the career change that started it all
Olivier Kretz spent more than 25 years in business before moving into real estate. In an interview with Focus, he described a career that included Procter & Gamble, Nielsen and technology company Prosodie. His sales and marketing background gave him experience finding customers, developing relationships and explaining the value of a product.
Sandrine was a schoolteacher, with a strong interest in decorating and the way people live in their homes. Her contribution was different but complementary: seeing what made an interior attractive and understanding the emotional side of moving. Together, the couple brought commercial experience and a personal approach to their new venture.
Buying their own distinctive house helped trigger the change. The Boulogne-Billancourt property, associated with French writer André Malraux, became central to their family story. It also offered a setting where professional life could grow alongside the household, instead of taking place in a conventional storefront office.
They founded the agency in 2007. That meant launching just as the financial crisis was beginning to unsettle property markets. The business grew through relationships and a focus on unusual homes, with the family identity becoming an advantage they could carry into every listing.

How much money does the Kretz agency make?
The family operates in a market where a single successful sale can generate a substantial fee. Its Kretz & Partners 2023 company accounts provide concrete business figures: a revenue reference of approximately €7.21 million, €324,623 in net profit and roughly €1.63 million in shareholders’ equity. Gross payroll for that company was close to €1.60 million.
Those numbers reveal the organization behind the glamorous showings. A luxury brokerage needs agents, support, photography, marketing and the time to keep difficult transactions moving. The spectacular closing is the last scene of a much longer commercial process.
By 2025, the group reported more than €500 million in completed property transactions. This is the total value of properties changing hands through its work. The agency’s revenue comes from the fees attached to those transactions, alongside its other professional activities.
Kretz Real Estate commissions: 5%, 6% or 7%
The published 2025 fee schedule, still displayed on the agency’s website, sets out the following charges for sales mandates:
| Property category | Published sales fee |
|---|---|
| Apartments, houses and private mansions in Paris and Île-de-France | 5% including VAT |
| Apartments, houses and private mansions outside Paris and Île-de-France | 6% including VAT |
| Castles and manor houses | 7% including VAT |
At a 5% fee, a €3 million sale produces €150,000 in agency fees including VAT. The seller receives the proceeds from selling the property, while the agency’s fee pays for the brokerage service. The listed rates vary by location and property type, so there is no single percentage that describes every Kretz deal.
For an American audience, TTC on the French schedule means that VAT is included. And an hôtel particulier is a private urban mansion, a recurring star of the series. It is one of the distinctive property categories that helps give this Parisian business its character.

How the brothers share commissions
The family has described sharing commissions and bonuses rather than treating every sale as a contest between siblings. One brother may bring in the seller, another may lead the showing and a third may find the buyer. The shared approach rewards the group’s result.
It also makes room for different responsibilities. A brother building connections in another country cannot spend every day closing Paris transactions. Pooling rewards helps the family support that work while keeping the main business running.
For viewers, the arrangement explains why the dinner table can double as a strategy meeting. The brothers have individual ambitions, yet the outcome of a difficult deal belongs to a wider team. That tension supplies both a business structure and some of the show’s most entertaining conversations.
The Parisian Agency: what Netflix changed
The French program, L’Agence: l’immobilier de luxe en famille, began in 2020. International viewers know it as The Parisian Agency: Exclusive Properties, the title used by Netflix. It follows the same family as they help clients buy and sell exceptional homes in France and abroad.
The agency now presents a series spanning six seasons and 140 countries. That reach creates an extraordinary introduction to the Kretz name. A buyer living far from Paris can become familiar with the people behind the business before making an inquiry.
The show has two attractions working together. The properties deliver the spectacle: terraces, swimming pools, historic architecture and views that could fill a travel magazine. The family supplies continuity, with work disagreements, milestones and plans for the future running across episodes.
Netflix’s commercial value to the agency extends beyond a particular broadcast week. A viewer can discover an older season and later contact the company about a property. The family has turned a television audience into a continuing source of recognition for a business founded years earlier.

Season six: famous clients and a wider world
Season six premiered on France’s TMC on November 20, 2025. The official TF1 program announcement included a wooden house listed by entrepreneur Marc Simoncini, a rental search for Adriana Karembeu and a Mallorca villa search for designer Agatha Ruiz de la Prada. Destinations included South Africa, Portofino and Mykonos.
The announcement also featured a padel outing with Tony Parker. His world of sport and investment makes him a natural fit for the agency’s network; our profile of Tony Parker’s NBA earnings and business interests follows that wider career.
Produced by Réservoir Prod and Story Nation Productions within Mediawan, the series keeps pairing professional ambition with family life. The varied destinations show why international relationships matter to the brokerage: the same client can be interested in a Paris residence, a Mediterranean vacation home and a rental abroad.
A €1 million Paris flagship on Rue du Bac
On January 30, 2026, Kretz opened its first Paris flagship at 100 Rue du Bac, in the 7th arrondissement. The premises cover 320 square meters, with a reported €1 million investment and three and a half months of work, according to Immomatin.
The design turns the family’s story into a place to meet clients. Six spaces reflect the tastes and interests of different relatives, including Sandrine’s attachment to Brazil and Olivier’s to Trouville. Properties are presented on tablets instead of covering the windows with conventional listing cards.
The setting gives clients a taste of the atmosphere they recognize from the program. Comfortable rooms invite a conversation about how someone wants to live, while the address provides a base for a much larger professional network.
The office attracted English-language design coverage from Wallpaper, which described the contribution of Sophie Darriere of Label Experience. The result is a tangible next step for a business that built its reputation around digital presentation and a family home.

The luxury homes behind the Kretz reputation
The family’s specialty is presenting properties with a story. A Paris mansion, an Alpine chalet and a contemporary villa each demand a different conversation about architecture, location and daily life. Their selling style brings those details into view instead of reducing the house to a bedroom count.
One documented example is the €8 million sale of a house in La Muette, covered by AD in October 2023. Built around 1900, the approximately 300-square-meter home stood in a private lane facing the Ranelagh gardens. A 30-square-meter terrace added outdoor space in a sought-after part of western Paris.
Other properties made headlines through their asking prices. A 2022 Forbes Monaco feature described an Avenue Foch mansion listed at €80 million. At that level, the buyer pool is narrow and the ability to reach the right international contacts becomes especially valuable.
The Hallyday villa is another recognizable name in the agency’s property story. Celebrity homes bring an extra layer of attention to an already unusual listing, linking architecture with the lives of people viewers know. The broader Hallyday family story also features in our account of David Hallyday’s music career and fortune.

These homes are properties marketed for their owners. The Kretzes’ professional achievement lies in winning the mandate, presenting the residence and connecting it with a buyer. Their name becomes more valuable as that record of work expands.
Real estate offers several routes to wealth. Luc Poirier’s career in development and investment illustrates the project-building side of the industry. The Kretz family made brokerage, client relationships and property presentation the core of its business.
Four Kretz brothers, four different paths
The sons did more than step into identical jobs. Their backgrounds in business, engineering, international property and hospitality helped the agency develop a broader set of skills. Each brought something that the founders could use as the company grew.

Martin Kretz: negotiating and building the next business
Martin, the eldest brother, studied business in Montpellier and lived in Chile and Mexico. His international experience preceded his prominent role in the family agency. On the show, he often brings the energy of a salesperson eager to get a deal moving.
His work also extends to Kretz Club, which he cofounded. That project takes the relationship-building skills used in property transactions into a community of entrepreneurs and investors. The common thread is bringing people together around an opportunity.
Martin’s path captures the ambitions of the second generation. Managing the parents’ existing business is one responsibility; developing services that give the family a new source of activity is another. The club makes that expansion especially visible.
Valentin Kretz: engineering and international real estate
Valentin trained as an engineer and gained experience overseas. In his Forbes Monaco interview, he described working in residential real estate in New York and office property in the Philippines. He returned to Paris in 2014, helped his parents and ultimately stayed in the family company.
That background is useful when an international client approaches a French property search. Familiarity with other markets helps him understand different expectations and organize relationships that cross borders. His interest in technology also fits the agency’s emphasis on digital communication.
Alongside Martin, Valentin is a leading figure in Kretz Club. Together, their work shows how the brothers are adding activities to the original brokerage while drawing on the same network and reputation.
Louis Kretz: hospitality experience and the move to Spain
Louis worked in hospitality before joining the agency in 2017. Service experience translates naturally into high-end property: clients expect attention, responsiveness and someone who notices the details that matter to them.
He later became a co-leader of Kretz Spain with his wife, Adriana Pinos. In an October 2025 Cinco Días interview, the Spanish operation reported €1.3 million in revenue and 18 sales for 2024. Madrid, Barcelona, the Costa del Sol and the Balearic Islands give the business access to several different luxury markets.
Louis lives in Barcelona. In a March 2026 El País interview, he described cooking, spending time with family, swimming and playing padel. Those details give a more personal view of the Spanish chapter: an expanding professional role alongside a home life in a city he considers his own.
Raphaël Kretz: the youngest brother moves into expansion
Raphaël now works in the business, following real estate studies combined with experience at the family agency. The October 2025 Cinco Días interview identifies him as head of international development.
That marks a significant change from the early seasons, when viewers knew him as the youngest son still finding his direction. He is now part of the agency’s effort to establish itself in additional markets.
His progress adds another stage to the family’s business story. The parents started the company, the older brothers developed their specialties, and the youngest has moved into a role connected to its next phase of growth.

Who owns the Kretz family business?
The 2023 Kretz & Partners accounts list Sandrine and Olivier with 27.5% each, while Martin, Valentin, Louis and Raphaël held 11.25% each. The six family members together owned all the shares in that company at that date.
Their involvement therefore goes beyond appearing on television or working as agents. They have an ownership interest in the company they are helping develop. A successful family enterprise can create wealth through business profits and the value of those shares.
Operational roles remain distinct. Client relationships, negotiations, international development and new services require different kinds of attention. Alexandre Bruneau joined as chief executive in 2023, helping structure the wider organization around the founding family.
International franchises: taking the Kretz name abroad
In March 2026, the group described a franchise program with initial locations in Brussels and Mauritius and a goal of three more openings during the year. The idea is to combine the Kretz brand with entrepreneurs who understand their own local luxury markets.
According to Bruneau’s interview with Immomatin, the entry fee starts at €50,000 per city. The network royalty is 11% of the franchisee’s revenue, including 3% for communications. Those are fees for operating within the branded network and receiving its services.
The official franchise presentation emphasizes training and support, along with physical offices reflecting the family’s recognizable style: Art Deco influences, family photographs, a gong and a swing. It brings the atmosphere of the series into places where a member of the family may not lead every showing.
This is the practical test of expansion: turn personal reputation into a consistently good experience delivered by a wider team. A related French business story appears in our profile of Stéphane Plaza and his real estate network, another example of television recognition meeting property brokerage.

Kretz Club: membership, networking and investment opportunities
Kretz Club connects entrepreneurs, executives and investors interested in prestige real estate. In September 2026, the club’s website lists annual membership at €2,000 including VAT, with access to its community, events and opportunities presented by partners.
The launch partnership with ClubFunding mentioned investments starting at €1,000 for certain operations. That was an investment amount for a project, separate from the annual membership fee. Crowdfunding operations are offered and run by the approved partners, including ClubFunding and Baltis.
For Martin and Valentin, the club extends the network they developed through brokerage. A professional event or introduction can begin a relationship that later leads to a property conversation. The activity gives the Kretz name a role beyond a single purchase or sale.
It also broadens the way clients engage with the family. Some will first encounter the Kretzes through a television episode, others through an agent, and others through a club event. Real estate remains the common interest tying those relationships together.
The Kretz family house, Brazil and life away from a showing
The 1930s Art Deco home in Boulogne-Billancourt, just west of Paris, is one of the most recognizable settings in the family’s story. Olivier and Sandrine bought it before founding the agency. It later served as both a workplace and the center of family life.
That mix gives the program much of its warmth. A conversation about a listing can turn into a discussion between parents and sons without anyone leaving the room. The house feels lived in, which distinguishes it from the immaculate properties the family visits professionally.

Brazil also has a place in Olivier and Sandrine’s life. French coverage has featured the second home they acquired there. Their connection to the country appears again in the design of the Paris flagship, linking a personal attachment with the agency’s public identity.
For Louis, home life now includes Barcelona. For the family together, travel, meals, sporting events and time between assignments continue to provide the quieter scenes around the luxury listings. Those ordinary moments help explain why viewers become attached to the people as much as the houses.
Bienvenue à L’Agence: the family story becomes a book
The Kretzes also brought their story to bookstores with Bienvenue à L’Agence, published by Fayard on March 27, 2024. The 320-page book brings together the voices of the parents, their sons and Majo, the grandmother familiar to viewers.
Its French title means “Welcome to the Agency.” The book explores the business’s beginnings, the family’s relationships and the disagreements that come with working together. It gives readers more space with the personalities whose lives appear in fragments during the television series.
Publishing adds another chapter to a brand built across real estate, television and digital media. With a combined fortune estimated at €30 million, the family’s strongest commercial idea remains remarkably personal: make the Kretz name a reason for clients to open a conversation, then turn that relationship into lasting business.
