Koch Industries

Throughout his career at Koch Industries, David Koch demonstrated a combination of technical expertise and business acumen. After working as a technical services manager, Koch was promoted to the president of his division, Koch Engineering, in 1979.

Renamed the Chemical Technology Group, the new position allowed him to continue shining within the company as an innovative technician. A legal dispute between Charles and David Koch and their twin brother, Bill, and their father, Frederick, led to Charles and David becoming the majority owners. This move significantly increased his net worth, and by 2010, the brothers owned 42% of Koch Industries, where David served as Executive Vice President until 2018.

 

Philanthropy

Like many other highly successful businessmen, such as Bill Gates, David Koch also invested in philanthropic endeavors. This includes extensive contributions to medical research and development, notably funding research to discover a cure for cancer.

In 2007, he contributed over $100 million and made additional smaller donations to establish the David H. Koch Institute for Integrative Cancer Research. His funding has also been used to develop cures and assist with research into hearing loss and restoration at the House Ear Institute.

Educational initiatives have also received support and funding from David Koch, with a $10 million donation to PBS and the American Museum of Natural History. Koch has also supported the arts in the United States as the longest-serving trustee of the American Ballet Theater and other notable institutions.

In 2008, Koch pledged $100 million to renovate the New York State Theater, which was renamed the David H. Koch Theater in his honor.

Introduction

Robert Herjavec is a Croatian-born Canadian investor, businessman, and television personality with an estimated net worth of $300 Million

 

Before Wealth & Fame

Believe it or not, Robert Herjavec’s career began in the film industry as an assistant director. He worked behind the scenes on numerous productions, including The Return of Billy Jack and Cain and Abel. He also served as a field producer with Global TV for the 1984 Winter Olympic Games in Sarajevo, Bosnia.

A couple of years later, Herjavec learned of an opening at a computer startup called Logquest, which sold IBM mainframe emulation boards. The job paid $30,000 per year, but he was underqualified for the position. Still, Herjavec managed to secure the job by offering to work for free for the first six months. To keep food on the table, he waited tables during the evenings until Logquest paid him a full-time salary. Robert quickly rose to become president of the company, but was fired in 1990.

 

BRAK Systems

Following his dismissal, Robert Herjavec launched his first major company, BRAK Systems, which was one of Canada’s first cybersecurity companies. The company helped Canadian businesses procure and integrate network security solutions, and was operated entirely out of Herjavec’s basement. Ten years later, in 2000, AT&T acquired BRAK Systems for $30.2 million.

 

The Herjavec Group

After AT&T acquired BRAK Systems, Robert Herjavec became the vice president of Ramp Network, though the company was sold to Nokia for $126 million just several months later.

In 2003, now with a substantial amount of money to his name, Robert Herjavec founded the Herjavec Group, which quickly became one of the fastest-growing technology companies in Canada. The business also operates in the cybersecurity industry and has since merged with Fishtech Group and rebranded to Cyderes. The company currently reports annual revenues of $108.4 million and employs 425 people.

Apax Partners acquired a majority stake in The Herjavec Group in 2021, but Robert is believed to still hold a stake in the company. He also continued to serve as the CEO of Cyderes until 2024.

 

Shark Tank

By the time Robert Herjavec joined Shark Tank in its debut season in 2009, he already had a net worth in the tens of millions of dollars. Before Shark Tank began airing, Herjavec had actually been involved in Canada’s Dragon’s Den since 2006. He joined fellow sharks Daymond John, Lori Greiner, Mark Cuban, Barbara Corcoran, and Kevin O’Leary.

Thus far, Herjavec has starred in all seventeen seasons of Shark Tank, appearing in 323 episodes. According to our research, he’s invested approximately $7.58 million in 39 companies that have pitched in the tank. Several reports suggest that Herjavec has invested more than $16 million, but they also include failed post-show negotiations. Not every deal that’s accepted on the show actually gets finalized. Here’s a list of the companies that accepted Herjavec’s offer on the show, but ultimately fell through afterward:

  • Gift Card Rescue
  • Soy-Yer-Dough
  • Mod Mom Furniture
  • Hill Billy Brand
  • Orig Audio
  • You Smell Soap
  • Focus Designs
  • Henry’s Humdingers
  • Oru Kayak
  • Kronos
  • Zero Pollution Motors
  • SynDaver Labs

ZinePak$362,5008.7%S.6 Ep.26
Total$7,580,833

While that’s a lot of investments to cover, here’s a list of every company Herjavec has invested in on Shark Tank. The table above shows that Robert Herjavec has invested in 39 companies, totaling $7.58 million of his own money. Bear in mind that many of these investments were joint deals made with one or more sharks, but we’ve calculated Herjavec’s share of the investment. 

For two of the deals on the list, Herjavec didn’t receive any equity. Herjavec split a $1450,000 investment in Coffee Joulies with Kevin, Lori, and Daymond for the following:

  • Retail royalty – $6 per unit
  • Wholesale royalty – $3 per unit
  • Perpetuity after recouping their investment – $1 per unit

When Herjavec invested $150,000 into Wall Rx in episode 14 of season five, he didn’t want any equity. Instead, he invested the money in exchange for the rights to sell the product internationally.

While many of these businesses have since closed their doors or filed for bankruptcy, others have continued to thrive. Which begs the question, which of Herjavec’s Shark Tank investments have been the most successful?

 

Tipsy Elves

Details: $100,000 investment for a 10% stake

After the founders of Tipsy Elves appeared on the fifth season of Shark Tank, they secured a $100,000 investment from Herjavec for 10% of the business. Tipsy Elves launched as an e-commerce business selling Christmas sweatshirts and has since expanded into Halloween costumes, Hawaiian shirts, and other themed clothing.

By 2025, twelve years after appearing on the show and securing investment, Tipsy Elves’ lifetime sales exceeded $317 million. According to Herjavec himself, this was by far his best investment from Shark Tank.

 

Divorce Settlement

In July 2014, after 24 years of marriage and three children together, Herjavec’s relationship with then-wife Diane Plese came to an end, with Plese filing for divorce in March 2015, claiming that Herjavec had been having extramarital affairs with another woman.

The settlement, ruled by an Ontario Supreme Court, was finalized in 2016 and required Herjavec to pay Plese $125,000 a month in spousal and child support with no set termination date, a $2.6 million equalization payment, and an extra $2.5 million once all their assets had been divided and sold, bringing her total settlement from the marriage to $25 million.

Some of their joint assets included a $17.4 million mansion in the Bridal Path area of Toronto, a $4.8 million holiday home on Fisher Island, Florida, as well as top-of-the-line luxury boats and automobiles, including a rare $1.5 million Ferrari, and several other high-end items.

After the settlement, it was reported that Herjavec struggled with suicidal thoughts and depression following their separation, especially over the estrangement from his children. However, he continued with his life, appearing on season 20 of Dancing with the Stars in 2015 and subsequently marrying his co-star, Kym Johnson, a year later in 2016.

David Packouz Net Worth

David Packouz Net Worth
Net Worth:$2.9 Million
Age:44
Born:February 16, 1982
Gender:Male
Height:1.70 m (5 ft 7 in)
Country of Origin:United States of America
Source of Wealth:Arms Dealer
Last Updated:Jul 14, 2026

Introduction

David Packouz is an American former arms dealer, musician, inventor, and entrepreneur with an estimated net worth of $2.9 Million. 

In this profile, we’ll discuss our research into David Packouz’s net worth, income sources, and the legal issues he faced from arms dealing.

 

Quick Facts

  • Secured a $298 million arms contract with the U.S. government in 2007
  • Previously faced 355 years in federal prison for defrauding the government
  • Filed a $5 million lawsuit against his former business partner for unpaid fees
  • Settled the dispute for a small fraction of that figure

 

AEY Inc.

In 2005, at just 23 years old, David Packouz reunited with his childhood friend, Efraim Diveroli, who was 25, to enter the world of arms dealing. Diveroli had already been running AEY, bidding on U.S. government surplus and supply contracts online. However, most of his contracts were small, but he still earned $1.8 million in a single year, enticing Packouz. 

When Packouz and Diveroli partnered with one another, the United States was in the middle of the Afghan war against al-Qaeda and the Taliban. During the war, the government spent $18.6 billion on weapons, vehicles, aircraft, and equipment to arm the Afghan National Defense and Security Forces. To supply much of this equipment, the U.S. government would often offer contracts to third parties, which is where AEY Inc. comes in.

Packouz and Diveroli, barely in their mid-20s, landed a $298 million contract with the U.S. Army in January 2007, to supply the Afghan National Army and Police with millions of rounds of ammunition, specifically 7.62mm ammunition used in AK-47 rifles.

How did such a small company land such a high-value government contract? They lowballed the competition. The crucial stipulation of the contract was that they couldn’t source the ammunition from Communist Chinese military companies. In other words, the ammo couldn’t originate from China in any form.

AEY eventually sourced a substantial portion of the 7.62mm rounds from MEICO, an Albanian state-owned supplier. The rounds had been stored in an Albanian warehouse for decades, but were originally manufactured and packaged in China. AEY repackaged the Chinese ammo, but investigators later found out, largely because Diveroli left a note on his desk that said “Repackage Chinese ammo.”

 

2008 Arrest

In 2008, Packouz, Diveroli, AEY Inc., and two other individuals were indicted by a federal grand jury on charges of conspiracy to defraud the United States and wire fraud.

Packouz was initially facing 355 years in federal prison due to the number of times ammo had been shipped. Each time AEY shipped a load of ammunition by air, they listed the place of origin as Albania, even though it was manufactured in China. Since they repeated the process 71 times, they were facing 71 counts of fraud, not just a single count.

A year later, Packouz pleaded guilty and was fortunate enough to receive just 7 months of home detention and 14 months of probation. Diveroli received a 4-year federal prison sentence.

 

Lawsuit

Bear in mind that while AEY, Inc. was shipping ammunition to the military forces in Afghanistan, David Packouz wasn’t being paid. Diveroli held out on paying him until the contract was fulfilled in its entirety. Packouz claimed that Diveroli owed him $5 million and filed a lawsuit against his former partner after Diveroli’s release from prison.

Unfortunately, evidence went missing, and money was hidden, so Packouz ultimately settled for “a small fraction of what he owed me.” When asked how much? Packouz replied with “I’d rather not say. It’s too painful.” Diveroli allegedly earned $15 million from the contract.

 

War Dogs

Given his eventful past, a film titled War Dogs was released in 2016, based on David Packouz’s life, starring Jonah Hill and Miles Teller. Since the story was based on his life, Warner Bros. acquired his life rights to make the film.

Recently, in 2025, David revealed in an interview with VladTV that he was paid a modest sum for the rights. He also joked that Teller, who played him in the film, earned substantially more than he did.

 

Real Estate

The film shows Packouz purchasing a penthouse in Miami, Florida, but in real life, this apparently wasn’t the case. He actually rented out a townhouse with his business partner, Efraim Diveroli, in Miami Beach. According to Zillow, this property is currently valued at $5.77 million. Packouz still resides in Miami, though it’s not clear exactly where.

Introduction 

Alain Wertheimer is a French businessman and investor with an estimated net worth of $45 Billion.

Wertheimer’s grandfather, Pierre Wertheimer, co-founded Chanel with Gabrielle “Coco” Chanel in 1910. More than a century later, Chanel, one of the world’s largest luxury brands, remains 100% privately owned, which is impressive in and of itself.

Alain Wertheimer is believed to be a 50/50 owner with his brother Gérard of a company that now has 38,000 employees, generating more than $19 billion in revenue and $4.7 billion in annual profits.

This profile outlines our research into Alain Wertheimer’s net worth history, income sources, and real estate investments.

 

Quick Facts

  • Debuted on the Forbes Billionaires Index in 2001
  • Joint net worth of $5 billion with his brother at the time
  • Holds a 50% stake in the luxury fashion brand Chanel
  • The business is 100% privately owned by the Wertheimer family
  • Received $7 billion in dividends between 2019 and 2024

 

Net Worth History

YearNet Worth
2016$11 Billion
2017$11.8 Billion
2018$13 Billion
2019$14.6 Billion
2020$17.1 Billion
2021$34.5 Billion
2022$31.2 Billion
2023$31.6 Billion
2024$36.8 Billion
2025$30 Billion

As we briefly mentioned above, Alain Wertheimer debuted on the Forbes Billionaires Index in 2001, in a joint listing shared with Gérard. After their father, Jacques Wertheimer, died in 1996, the brothers inherited control, and five years later, held a combined net worth of $5 billion. Perhaps what’s still most impressive is that the company remained family-owned, despite its size and longstanding history.

The brothers remained on Forbes in a joint listing for several years thereafter, reaching a combined net worth of $10 billion in 2007. 

By the mid-2010s, they received separate listings, and in 2017, Alain was worth an estimated $11.8 billion. For the remainder of the decade, his fortune grew by between $1 billion and $2 billion per year, reaching approximately $17.1 billion in 2020.

However, the situation rapidly changed between 2020 and 2021, when Chanel’s annual revenues skyrocketed in the year following the COVID-19 pandemic. For the year ended 31 December 2021, the company reported revenues of $15.6 billion, an increase of 49.6% versus 2020. More importantly, Chanel’s operating profits reached $5.46 billion, a 170.6% increase over the prior year.

Additionally, Chanel began publishing financial statements in the UK during this time, providing the public with much more information. As a result of this growth and increased information, Forbes revalued the company and updated its estimate of Alain’s net worth to $34.5 billion, more than double the 2020 estimate. By this point, the Wertheimers’ fortunes weren’t derived solely from Chanel’s valuation. They were also receiving substantial annual dividend payments.

Since then, Alain and Gerard’s individual net worths have hovered between $31 billion and $37 billion; however, at the time of writing, Alain currently has an estimated fortune of $39.4 billion.

 

Chanel Dividends

Thanks to the new financial statements that Chanel began publishing in the United Kingdom in the late 2010s, we can see some significant dividend payouts to the brothers. These payments are listed as company-wide dividends, but since Alain and Gerard each hold a 50% stake, you would assume the same applies to any dividends.

Between 2019 and 2024, Chanel reported dividend payouts as follows:

  • 2019 – $1.7 billion
  • 2020 – $0
  • 2021 – $5 billion
  • 2022 – $1.7 billion
  • 2023 – $5.7 billion
  • 2024 – $0

Thus, we can see that the total dividends paid to the brothers during the period amount to $14.1 billion. In theory, this would have provided Alain with a little more than $7 billion over six years.

 

Real Estate

Alain Wertheimer previously owned a 62-acre estate in Washington, Connecticut. The home on the land comprises 6,932 square feet and has five bedrooms and eight bathrooms. Reports on the property’s transaction are limited, but according to Realtor.com, it sold for just $35,000 in January 1997, which we believe was when Wertheimer acquired it. Sources suggest that he sold this home for $3 million in October 2003.
