See the ‘Shark Tank’ Cast Then and Now

Daymond John: Seasons 1 – present

By the time John joined Shark Tank’s original cast in 2009, he had already established himself as a prominent entrepreneur after founding fashion brand FUBU at just 23 years old and writing the bestselling book The Power of Broke.

One of John (and the show’s) biggest success stories is his investment in Bombas socks, and he also made major deals with Bubba’s-Q Boneless Ribs and Mission Belt.

In 2016, John welcomed a daughter, Minka Jagger, with Heather Taras, whom he proposed to on the set of Shark Tank four months later. They got married in June 2018.

In 2024, John teased that he would likely leave the show someday — but not anytime soon.

“I absolutely will not be on the show forever because I do think there’s time to make room for others,” he told PEOPLE at the time, though he was in no rush to move on. “It is safe to say that I don’t have any plans to leave, but you never know.”

Robert Herjavec: Seasons 1 – present

Robert Herjavec brought an international perspective to the original Shark Tank team. Born in Croatia before moving to Canada, he co-founded internet security firm BRAK Systems, which he later sold to AT&T Canada for more than $30 million in 2000. He then founded another cybersecurity firm, the Herjavec Group, before joining Shark Tank in 2009.

Always honest but empathetic, Herjavec has made some incredible deals on Shark Tank, including Tipsy Elves, an apparel company.

Since first appearing on Shark Tank, Herjavec’s personal life has flourished. After meeting pro dancer Kym Johnson on Dancing with the Stars in 2015, the pair got married in 2016.

“Robert just has so much passion about everything he does which is just so great to be around. He’s just very positive,” Johnson told PEOPLE. “I think that’s why he’s so successful in everything he does.”

The pair also welcomed twins Haven Mae and Hudson Robert Herjavic on April 23, 2018.

Kevin Harrington: Seasons 1 – 2

Kevin Harrington was one of the original Shark Tank sharks, joining the cast in 2009 with a wealth of experience as the inventor of the modern infomercial and cofounder of HSN Direct.

Harrington only spent two seasons on Shark Tank, but he made his mark while he was there, having invested in memorable products like the The Uro Club — a gag gift golf club that doubles as a urinal.

Harrington never gave a reason for leaving the show, and has only had positive things to say about his time on Shark Tank.

“It’s been a phenomenal experience,” he told All Business at the time. “I’ve learned even more about brokering deals in the heat of the moment with other sharks. You think you know what you’re doing, but there’s always more to learn. So, it’s been informative and fun.”

These days, Harrington is still a major voice in venture capital and entrepreneurship. He mentors business owners through his master class, and co-hosts a podcast called SharkPreneur.

According to his website, Harrington has now launched more than 500 products, and has written many books, including Act Now: How I Turn Ideas into Million Dollar Products, Key Person of Influence and Put a Shark in Your Tank.

Kevin O’Leary: Seasons 1 – present

When Shark Tank launched in the U.S. in 2009, Kevin O’Leary a.k.a. “Mr. Wonderful” was already a multimillionaire businessman after co-founding SoftKey Software Products, later known as The Learning Company, in the 1980s. He sold the company to Mattel in a blockbuster deal for more than $4 billion, per his LinkedIn.

Mr. Wonderful was a founding shark, arriving hot off Dragons’ Den with a reputation for being blunt.

“I’m not a tough guy. I just deliver the truth and only the truth,” he said on Facebook in 2022 of his rigid on-screen persona. “If you can’t deal with it, too bad. I’m not trying to make friends, I’m trying to make MONEY.”

In his time on the show, O’Leary has had many major successes, including Wicked Good Cupcakes, Talbott Teas (later acquired by Jamba Juice) and GrooveBook (later acquired by Shutterfly).

Mr. Wonderful has diversified his business since joining the show, including launching his bestselling Cold Hard Truth book series in 2011, creating the O’Leary Financial Group in 2014, establishing O’Leary Ventures in 2023 and even announcing his foray into acting in 2025, per Business Insider.

Barbara Corcoran: Seasons 1 – present

When she began as an original cast member on Shark Tank, Barbara Corcoran was already a New York real estate icon as the founder of The Corcoran Group, which she sold to NRT in 2001 for more than $60 million.

Already a TV personality who often appeared on programs like Today, she leaned into her reputation as a kind-hearted investor and mentor on Shark Tank.

She became known for choosing to work with people she connected with and believed in, even if they weren’t as established as other sharks would prefer. That attitude brought her major success through brands like The Comfy, Cousins Maine Lobster and Pipcorn.

While Corcoran admits she only makes money off about 10% of her Shark Tank investments, she’s proud to invest in the people over the products.

“The No. 1 trait I’m looking for [is] ambition,” she told CNBC in 2023. “Someone who envisions where they’re going, and I fall for it when they tell me they’re going there.”

Since she began appearing on the show, Corcoran has written several bestselling books and appeared on season 25 of Dancing with the Stars.

Mark Cuban: Seasons 2 – 16

Mark Cuban was the first non-original shark to join the cast in season 3 after guest-starring in season 2. When he came to Shark Tank, he had started and sold a few businesses, but the big one was AudioNet, which he co-founded in 1995 and sold to Yahoo! in 1999 for nearly $6 billion, making him the wealthiest shark.

While on the show, Cuban had a reputation for being tough but fair, with a disdain for scammers and a soft spot for young entrepreneurs. Some of his major investments from the show included Tower Paddle Boards, Nuts ‘n More, Beatbox Beverages and Dude Wipes.

Cuban’s influence has only grown since becoming a fan-favorite on the ABC hit show. He’s launched ventures like Sharesleuth, 2929 Entertainment and his affordable pharmaceutical venture, Mark Cuban Cost Plus Drugs.

In 2023, Cuban sold majority ownership of the Dallas Mavericks to become a minority owner, according to Sports Illustrated. Around the same time, he announced he would be leaving Shark Tank to “commit that time to my family and Cost Plus Drugs” instead.

Lori Greiner: Seasons 4 – present

When Lori Greiner first joined Shark Tank as a guest shark in season 3, she was already known as the “Queen of QVC,” thanks to the success of her long-running show Clever & Unique Creations.

She also had a reputation as a top-tier inventor and entrepreneur with more than 100 products to her name and over 100 patents under her belt.

Though she was comfortable on TV, Shark Tank was her first major mainstream television show outside of the TV shopping world, and she quickly made a name for herself on the cast after joining full-time in season 4, thanks to her consumer product and retail experience.

“I have relationships with most of my entrepreneurs. I love them,” she told PEOPLE in October 2024. “So they enrich my heart first and my soul first, and then we do good business together, and then we help other people, and we have a humanitarian bent usually, a give-back, and we make money. … We make money because we do all those other things.”

She hit it big with deals like Squatty Potty, Bantam Bagels and Scrub Daddy — the latter of which is one of the show’s biggest successes ever with more than $1 billion in sales, founder Aaron Krause told Philly Mag in April 2025.

The deal was enriching for Greiner in more ways than one.

“Not only am I super close to him and his family, I’ve gone on vacations with them, I have had holidays with them, they’ve enriched my life by who they are and that friendship,” she said of Krause and his family.

Today, Greiner is still a fan-favorite shark who has turned that success into many other business opportunities, including her bestselling book Invent It, Sell It, Bank It!, published in 2014. She now boasts over 1,000 products and over 120 patents, according to her website.

Daniel Lubetzky: Season 16 – present

Daniel Lubetzky first joined Shark Tank in 2019 as a guest for season 11. He is best known as the founder and executive chairman of the snack company Kind.

Lubetzky became the first shark to join the show full-time in over a decade when it was announced he would be one of the core sharks beginning in season 16.

“I’m much more comfortable now,” he told Decider in October 2024 after officially joining the regular cast. “I also negotiate a little bit harder with the sharks. As a guest shark, I didn’t want to cross certain lines. I was always worried that I was interrupting the other sharks, but I’ve since gotten over that.”

He often chooses to work with entrepreneurs who have a positive mission or an inspiring backstory.

“I want them to have integrity,” he told Decider. “I want them to have hustle. I want them to have grit.”

Some of his most successful investments on the show have included Yellow Leaf Hammocks, Quevos, Tandm Surf and HummViewer.

Since Shark Tank fans first met Lubetzky, he’s sold a controlling stake in his Kind business to Mars in a multi-billion-dollar deal in 2020, according to Forbes.
