When you think about really big companies, names like Apple, Google, or Microsoft might pop into your head. These companies are owned by lots and lots of people (stockholders) and are traded on the stock market. But did you know that some of the biggest and wealthiest companies in the world are still owned and often run by the same families who started them, sometimes over 100 years ago?

These are often called family owned companies, and they are like giant family businesses that never stopped growing! Instead of selling pieces of their company to anyone who wants to buy them on the stock market, the founding family (or their descendants) keeps most or all of the ownership. This often means the family has a strong say in how the company is run, sticking to values and ideas passed down through generations.

Finding the absolute richest family owned companies in the world is a bit tricky because, unlike public companies, they don’t have to share all their financial information. But we can look at the ones that make huge amounts of money (revenue), own valuable things (assets), and whose owning families are among the wealthiest business families globally because of these companies.

Learning about these largest family businesses in the world is fascinating. It shows how a good idea, hard work, and keeping things in the family can build incredibly successful businesses that last for a very long time. Let’s explore some of these impressive famous family empires and see how they got started and what they do!

1. Growing the World’s Food: Cargill

Cargill is a name many people haven’t heard of, but it’s one of the biggest companies in the world, and it’s owned almost entirely by the descendants of William W. Cargill, who started it in 1865. Think about all the food the world needs! Cargill is involved in almost every part of getting food from farms to your table. They buy, trade, and distribute grain and other farm products, make animal feed, process food ingredients, and much more.

They started right after the American Civil War with one grain storage flat house. Over more than 150 years, the Cargill and MacMillan families (descendants of the founder) grew it into a massive global business. Their success comes from being experts in agriculture and managing the complex process of feeding the planet. Because it’s private, the value isn’t public, but its sheer size and revenue make it one of the most significant and richest family owned companies globally, a true giant among largest family businesses in the world.

2. Fueling Industry: Koch Industries

Koch Industries is another giant company in the United States that is privately owned, mostly by the Koch family. It was built by Fred C. Koch, who developed a new way to refine crude oil in the 1920s and 1930s. Today, Koch Industries is involved in many different things – oil refineries, pipelines, making chemicals, manufacturing, even making things like Stainmaster carpet and Brawny paper towels!

Brothers Charles and David Koch expanded the company hugely over the decades. It’s one of the most diversified largest family businesses in the world. Like Cargill, because it’s not publicly traded, its exact wealth is private. But its massive revenues from its many different businesses make the Koch family one of the wealthiest business families, firmly placing Koch Industries among the richest family owned companies. Their history of successful family businesses is one of constant expansion into new areas.

3. Sweet Treats and Pet Needs: Mars, Incorporated

Who doesn’t love M&M’s, Snickers, or Skittles? Or maybe you have a pet that eats Pedigree or Whiskas food? All these famous brands come from one company: Mars, Incorporated. Started by Frank C. Mars in his kitchen in 1911, it’s still owned by the Mars family.

Frank started by making butter cream candy in Tacoma, Washington. His son, Forrest Mars Sr., later expanded the business significantly, introducing famous products like M&M’s and branching into pet care. The company is known for being very private about its operations. Despite this secrecy, the global popularity of its candies, chocolates, and pet foods generates enormous revenue, making Mars one of the most recognizable and most valuable family owned companies (though privately valued). It’s a sweet example of how a focus on popular consumer goods built one of the richest family owned companies.

4. Driving Luxury and Performance: BMW

When you see a sleek BMW car, you’re looking at a product from a company where one family still has a very strong influence: the Quandt family. BMW (Bayerische Motoren Werke AG) is a German company known for making luxury vehicles and motorcycles. While parts of BMW are owned by public shareholders, the Quandt family owns a large percentage of the voting stock, giving them significant control over the company’s direction.

The family’s involvement began in the early 20th century, but Herbert Quandt is credited with saving BMW in the late 1950s and investing heavily to turn it into the successful luxury brand it is today. The Quandt family’s continued major ownership means BMW, while publicly listed, operates with the significant influence of a wealthiest business families. Their stake in this global automotive giant makes BMW a fascinating example on a list of top family owned companies with a unique ownership structure among the richest family owned companies.

5. Discount Retail Giants: Schwarz Group (Lidl, Kaufland)

If you shop at Lidl or Kaufland supermarkets in Europe or other parts of the world, you’re buying from the Schwarz Group, a massive German retail company owned by the Schwarz family. Josef Schwarz initially became a partner in a fruit wholesale business in 1930, and his son Dieter Schwarz later built the business into the retail powerhouse it is today, particularly by creating the Lidl discount store chain in the 1970s.

The Schwarz Group is now one of the largest retailers globally by revenue. They are known for their efficient operations and competitive pricing. Dieter Schwarz is very private, and the company shares little public information. However, the sheer scale of their operations and global presence makes the Schwarz Group one of the largest family businesses in the world and undoubtedly one of the richest family owned companies, demonstrating how family businesses stay rich through scale and efficiency in essential industries like retail.

6. Hazelnut Heaven: Ferrero Group

Think Nutella, Ferrero Rocher, Kinder Surprise! These delicious treats come from the Italian company Ferrero Group, started by Pietro Ferrero in 1946. He was a pastry maker who created a hazelnut spread because chocolate was rationed after World War II. His son Michele Ferrero turned it into the global phenomenon it is today, creating many of the famous products.

The company is still owned and run by the Ferrero family, currently led by Giovanni Ferrero. They are known for their secrecy and dedication to quality. By focusing on beloved, high-quality confectionery products that are popular worldwide, the Ferrero Group generates massive sales. Their focus on specific, successful products over generations makes them a prime example on a list of top family owned companies and one of the most valuable family owned companies in the food industry, a sweet addition to the famous family empires.

7. Luxury Craftsmanship: Hermès

For centuries, the name Hermès has been associated with exquisite luxury goods, particularly leather items like the famous Birkin and Kelly bags, silks, and perfumes. The company was founded in Paris in 1837 by Thierry Hermès, originally as a workshop creating high-quality harnesses and bridles for horses.

Over six generations, the family expanded into saddles, then luggage, and eventually handbags, scarves, and other luxury items, always focusing on incredible craftsmanship and quality. Today, the Hermès family still owns a significant portion of the company and maintains a strong influence, even though it is publicly listed. This dedication to heritage, quality, and family control over generations has kept Hermès at the very top of the luxury world, making it one of the most prestigious and most valuable family owned companies with deep roots in the history of successful family businesses.

8. India’s Industrial Giant: Tata Group

The Tata Group is one of India’s largest and most respected conglomerates, involved in everything from cars (Tata Motors) and steel (Tata Steel) to software (TCS) and tea (Tata Tea). It was founded by Jamsetji Tata in the mid-19th century. While the ownership structure is complex, involving trusts that support charitable causes, the Tata family name and descendants have historically held key leadership positions and maintained significant influence over the vast empire.

Often referred to as a “family conglomerate,” the Tata Group’s sheer scale and diverse businesses make it incredibly valuable. Its long history of industrial development in India highlights a significant history of successful family businesses on a global scale. While not owned directly by one family in the same way as some others, the Tata family’s legacy and control mechanisms place the Tata Group firmly in the conversation of largest family businesses in the world and contribute significantly to the wealth of the wider Tata family influence, making it a unique entry on a list of top family owned companies.

9. Beauty Powerhouse: L’Oréal

L’Oréal is the world’s largest cosmetics company, with countless brands covering makeup, skincare, haircare, and perfume. It was founded by Eugène Schueller in 1909, a chemist who developed a new hair dye formula. His daughter, Liliane Bettencourt, inherited his wealth and stake, and today her descendants, the Bettencourt Meyers family, are still major shareholders in the company.

While L’Oréal is a publicly traded company, the Bettencourt Meyers family owns a very large percentage of the shares, giving them significant control and making them one of the wealthiest business families in the world based on this ownership. Their continued stake in this global beauty giant ensures family influence remains strong. L’Oréal’s century-long history of innovation and marketing in the beauty industry makes it a powerful and enduring example on a list of top family owned companies with significant family involvement, highlighting how family businesses stay rich by dominating consumer markets.

10. Discount Grocery Empire: Aldi

Aldi is another German discount supermarket chain that is famously family-owned and incredibly successful. It was started by brothers Karl and Theo Albrecht after World War II, taking over their mother’s small grocery store. They built it into a large chain focusing on a limited range of products at very low prices. Eventually, the brothers split the company into two separate groups, Aldi Nord and Aldi Süd, due to a disagreement over selling cigarettes, but both remain privately owned by the Albrecht family’s descendants.

Like the Schwarz Group, Aldi is known for its efficiency and secretive nature. Despite being split, both Aldi Nord and Aldi Süd are massive retail operations with stores across Europe, North America, and Australia. Their success demonstrates how family businesses stay rich by mastering a specific business model (discount retail) and expanding it globally. The Albrecht family’s ownership of these two retail giants makes them one of the wealthiest business families and places Aldi firmly on the list of top family owned companies that dominate their industry.

From agriculture and industry to candy, cars, and cosmetics, these largest family businesses in the world have built enduring legacies. Their history of successful family businesses is filled with stories of innovation, hard work, and families working together (or sometimes splitting apart!) to build something great that lasts for generations. They offer fascinating insights into how family businesses stay rich by focusing on their core strengths and maintaining control over their destiny.
