Kevin O'Leary

O'Leary is famous for royalty deals. On Shark Tank, he frequently offers founders a deal where he gets a royalty per unit sold rather than (or in addition to) equity.

His logic: royalties start paying immediately, do not depend on an exit event, and give him guaranteed cash flow regardless of whether the company gets acquired. He also invests in ETFs and dividend-paying equities through his O'Shares brand.

He is very publicly diversified — he does not concentrate bets. He likes to say he treats every dollar as a soldier that goes out and brings back more soldiers.

Robert Herjavec

Herjavec invests in people first, businesses second. On Shark Tank, he consistently picks founders he believes in personally — even when the numbers are shaky.

His real investing is in cybersecurity, where he has deep domain expertise. Through Herjavec Group, he has built a massive managed services business that benefits from every new data breach headline.

His personal investments tend toward tech, consumer products, and businesses where he can add operational value. He is less aggressive on valuation than Cuban or O'Leary — he would rather take a smaller stake in a founder he trusts.

Kevin O'Leary

Every dollar is a soldier. Send it out to bring back more soldiers.

O'Leary's philosophy is entirely about cash flow and capital efficiency. He wants money working for him at all times.

He is against speculative investments that do not produce income. He is famously anti-debt for personal use but comfortable with leverage in business when the numbers work.

His mother taught him to save 10% of everything — he still follows that rule.

Robert Herjavec

Work harder than everyone else. Then work smarter.

Herjavec's philosophy is straightforward: success is earned through relentless effort, and immigrants who come from nothing often have an advantage because they know what losing everything actually feels like. He believes fear of returning to poverty is a more powerful motivator than the desire for wealth.

Kevin O'Leary

O'Leary caps any single position at 5% of his total portfolio. When something appreciates beyond that, he trims.

He never lets conviction turn into concentration. His royalty deal preference on Shark Tank is itself a risk management tool — royalties pay regardless of whether the company ever gets acquired or goes public, while equity only pays on an exit that may never come.

He has said the single biggest mistake retail investors make is falling in love with a stock and watching a 5% position quietly become 40% of their net worth before they notice.

Robert Herjavec

Herjavec fled Yugoslavia as a child with his family and $20. He knows exactly what it means to lose everything, which gives him a risk framework most Shark Tank investors don't have.

He is not cavalier with capital. He passes on deals with structural problems even when he genuinely likes the founders — he protects downside before he chases upside.

His professional life is itself built around risk: Herjavec Group exists to help companies manage cybersecurity risk, which means he understands risk assessment frameworks at a technical level. He brings that rigor to his personal investing.

O'Leary is flashy on camera — he wears a signature watch, talks about wine and luxury — but has spoken about being more measured in private. He collects fine wine and has a wine brand (O'Leary Fine Wines).

He runs every financial decision through a "what does this dollar do for me" filter. He has said he wakes up early, spends mornings on markets and email, and treats content creation and Shark Tank as businesses in themselves.

Herjavec is a car enthusiast — he owns Ferraris, Porsches, and races competitively in the Ferrari Challenge Series. He trains for races seriously.

He also won season 20 of Dancing with the Stars (where he met his second wife, dancer Kym Johnson). He wakes up early, exercises daily, and is known for being one of the most disciplined and personable people in the Shark Tank orbit.

Selling SoftKey / The Learning Company to Mattel for $4.2 billion. The fact that Mattel destroyed most of that value after the acquisition does not change the outcome for O'Leary — he negotiated the sale, collected his share, and moved on.

The deal remains one of the largest educational technology exits in history.

Herjavec Group. He founded it in 2003 with essentially a desk and a phone after selling BRAK Systems.

He grew it into one of the largest privately held cybersecurity companies in North America, with offices in multiple countries and over $200 million in annual revenue. As cybersecurity spending exploded globally, Herjavec Group was perfectly positioned.

Kevin O'Leary

The SoftKey-Mattel deal is simultaneously his biggest win and his most controversial chapter. Critics have argued that the company was aggressively managed for the sale rather than for long-term health — and that the $3.6 billion write-down at Mattel was foreseeable.

O'Leary disputes this and says the operational problems were Mattel's responsibility after the acquisition.

Robert Herjavec

He has been candid about his first marriage ending during the period when he was building Herjavec Group. He threw himself into work at the expense of his personal life and has spoken about the cost of that imbalance publicly.

On the business side, some of his earlier Shark Tank investments did not pan out — a pattern common to all the sharks, but Herjavec's empathetic investing style means he occasionally backs founders whose stories are stronger than their businesses.

Kevin O'Leary

Kevin O'Leary was born in Montreal in 1954 to an Irish-Canadian father and a Lebanese mother. His mother taught him about money early — she literally forced him to save a portion of every dollar he ever received.

He studied environmental science and then got an MBA from Western University (Ivey Business School). He co-founded SoftKey International in 1986, an educational software company.

Through aggressive acquisitions — buying The Learning Company, Broderbund, and others — SoftKey became the dominant educational software company in North America. It was sold to Mattel in 1999 for $4.2 billion.

Mattel subsequently wrote down $3.6 billion of that purchase price, calling it one of the worst acquisitions in corporate history. O'Leary was already cashed out.

He moved into TV, joining Canada's Dragon's Den in 2006 and Shark Tank in 2009. He also launched O'Leary Funds (mutual funds and ETFs), O'Shares ETFs, and various venture investments.

Robert Herjavec

Robert Herjavec was born in Varazdin, Croatia (then Yugoslavia) in 1962. His family fled communist Yugoslavia and arrived in Halifax, Canada in 1970.

They had almost nothing. His father worked in a factory for 22 years.

Young Robert delivered newspapers, worked at a gas station, and waited tables through school. He got into the tech industry by essentially talking his way into a sales role at Logiquest, a technology company.

He then founded BRAK Systems, an internet security firm, and sold it to AT&T Canada in 2000 for $30 million. In 2003, he founded Herjavec Group, a managed IT security company that grew to over $200 million in annual revenue.

He joined Canada's Dragon's Den in 2009, then Shark Tank in 2015, becoming one of the show's most popular and investor-friendly sharks.
