Robert Herjavec: Biography, Cyderes, Shark Tank Role and Net Worth Facts

Robert Herjavec is a Croatian-born Canadian entrepreneur who is best known to television audiences as one of the investors on ABC’s Shark Tank, although most of his wealth and reputation come from a long career in cybersecurity. People who search for his name usually want to know who he is, how he built his companies, whether he still runs Cyderes, how much he is worth, and who he is married to. This guide answers those questions using company announcements, major news outlets and public biographies, and it flags the places where online pages disagree or repeat claims that nobody has confirmed.

Quick Facts

From Croatia to Toronto: The Early Years

Herjavec spent his early childhood in the small village of Zbjeg, where his grandmother helped raise him, and the family left the country in 1970 when he was eight years old. By his own account, repeated in many profiles, his father had been jailed for criticizing the communist government; the figure of 22 arrests that he often quotes is his personal recollection rather than a documented count. The family arrived in Halifax, Nova Scotia, with very little money, and the Toronto Star has reported that they landed with only about $20 before eventually settling in Toronto.

Life in Toronto started out hard, since the family lived in the basement of a family friend’s home for about 18 months and Herjavec did not speak English when he arrived. To help support the household, he later worked a series of low-paid jobs that included waiting tables, delivering newspapers, retail sales and debt collection. In the mid-1980s he also took film and television work, including time as a third assistant director and a field producer for Global TV at the 1984 Winter Olympics in Sarajevo, according to Inc. magazine.

How Robert Herjavec Built His Business Career

His break into technology came when he applied for a sales job at Logiquest, a company selling IBM mainframe emulation boards, even though he was not qualified for the role. He offered to work unpaid for six months and waited tables at night to cover his rent, and he eventually rose to general manager before being fired in 1990. Later that year he founded BRAK Systems, an internet security integrator, from the basement of his home, and he sold it to AT&T Canada in March 2000 for a reported $30.2 million.

After that sale he joined Ramp Network as vice president of sales, and the company was later bought by Nokia for a reported $225 million, which was the price paid for the company rather than a figure that went to him personally. In 2003 he started The Herjavec Group, a security reseller and managed services provider that, by his own company’s description, grew from three employees and roughly $400,000 in sales to more than $200 million in annual revenue. Apax Partners bought a majority stake in 2021 while Herjavec stayed on as CEO, and in June 2022 the firm merged with Fishtech Group to form Cyderes.

Cyderes announced on September 24, 2024 that Chris Schueler would take over as chief executive. In that public statement, the company said its founder would remain a significant investor and board member, and Herjavec described Cyderes as his core business focus even as he spends more time on family and other investments. One of those outside interests was announced in March 2025, when the data company Zetaris named him an executive director in a press release.

Robert Herjavec on Shark Tank, Dragons’ Den and Investing

Before American audiences knew him, Herjavec appeared on the Canadian show Dragons’ Den, which uses the same format as Shark Tank. He then became one of the long-running investors on the American version, and he is also credited as an executive producer of the show in several official biographies. Sources disagree on exactly when he started: some profiles place his arrival in the first season in 2009, while episode listings clearly show him on the panel for all nine episodes of season 2 in 2011, and a number of low-quality pages claim he joined in 2013 or 2015, which does not match the episode records.

For the 2026 season, ABC announced that Robert Herjavec is returning as a permanent shark alongside Barbara Corcoran, Lori Greiner, Daymond John, Daniel Lubetzky and Kevin O’Leary, while Kendra Scott and Rashaun Williams have been promoted to permanent seats. Mark Cuban, who left after season 16, is not part of the panel.

Two of his deals come up often in coverage. Tipsy Elves, a novelty sweater company in which he took a 10% stake for $100,000, is frequently called his most successful Shark Tank investment, although that ranking is not backed by a solid published source. He also backed the herbal sparkling water brand Aura Bora, with media reports in January 2021 describing a $200,000 investment.

Robert Herjavec Net Worth: What Is Confirmed and What Is Not

No audited or officially published figure exists for Robert Herjavec’s personal wealth, and the pages that rank for this topic are a good example of why caution is needed. Many of them look auto-generated or copied from one another, and they contradict themselves on basic facts such as the year he joined Shark Tank. The most common estimate is about $200 million, another profile lists roughly $310 million, and some low-quality pages claim figures in the billions, none of which comes with a verifiable breakdown.

Part of the confusion comes from mixing up company numbers with personal ones. The $200 million figure often attached to his name was described as annual revenue for his security company, which is not the same as what he personally owns, and the sale prices of BRAK Systems and Ramp Network describe what buyers paid for those businesses. Claims about a per-episode Shark Tank salary also circulate online without any source, and I did not find a publicly confirmed price for the Apax Partners stake purchase, so any exact net worth should be treated as an estimate rather than a fact.

Family and Personal Life

The entrepreneur married optometrist Diane Plese in 1990, and the couple separated in 2014 before divorcing in early 2016. They have three children together. He has spoken publicly about struggling with depression and suicidal thoughts after the marriage ended, which makes his later story a candid one about recovery rather than only about business success.

His second marriage began with a television appearance, since he competed in season 20 of Dancing with the Stars in 2015 and was partnered with Australian professional dancer Kym Johnson. The pair finished in sixth place that May, confirmed their relationship in September 2015, got engaged in February 2016 and married in Los Angeles on July 31, 2016. Their twins, a boy and a girl, were born on April 23, 2018, which brings Robert Herjavec’s total to five children.

A 2017 Legal Dispute and How It Ended

In 2017, a former girlfriend filed a lawsuit against him containing serious allegations, shortly after he had sued her over what he described as an extortion attempt. Media reports from mid-2018 say both lawsuits were dismissed, that the allegations against him were withdrawn without any financial settlement, and that she apologized to him and his family. These details come from news coverage rather than court records that I could review, and the matter should be read as concluded rather than as an open accusation.

Homes and Hobbies

He owns a large home in the Bridle Path area of Toronto, which the Toronto Star reported he bought for $7.5 million and which has appeared on MTV Cribs, and he also has a home in Newport Beach, California. That second home led to an odd news moment in December 2023, when Canadian reporters met his private jet at Toronto’s airport because of rumors that it was carrying baseball star Shohei Ohtani, according to the Wall Street Journal. Ohtani was not on board and soon announced he was joining the Los Angeles Dodgers. Away from work, Herjavec is an avid golfer and runner who has completed marathons in Miami and New York, and he is also a certified scuba diver who owns several Ducati motorcycles.
