Shark Tank: meet the partners of Kevin O'Leary, Barbara Corcoran, and more

Kevin O'Leary, 71, just made his acting debut in one of the films of awards season. He starred alongside Timothée Chalamet and Gwyneth Paltrow in Marty Supreme. On screen, Kevin is one of the toughest Sharks on the show, but out of the spotlight, he's been married to wife Linda since 1990.

"We've been married a long time and I always tell people it's not a destination, marriage is a journey — and I think you have to have a lot of respect for your spouse or your significant other, no question," Kevin told Closer Weekly in 2019.

Like Mr. Wonderful, Linda is a businesswoman and served as the VP of marketing for O'Leary Wines. Together they're parents to two children, Trevor and Savannah.

Real estate mogul Barbara Corcoran, 76, has been happily married to former FBI agent Bill Higgins for 38 years. In a post celebrating their 33rd wedding anniversary, the Shark wrote to Instagram: "What I thought I wanted when I married Bill 35 years ago was an exciting, sexy guy to travel the world with! Now long into our marriage, I realize I've got the important stuff. A rock solid guy, a close friend, and a great father to our children."

In 1994, the couple welcomed their first child, a son named Tom, via in vitro fertilization with the help of her sister Florence, who donated an egg. They later adopted another child, a daughter named Kate.

FUBU founder Daymond John, 56, is married to Heather Taras. In 2016, after dating for several years, the couple welcomed a daughter named Minka Jagger. 

Of his proposal to Heather, Daymond told Harry Connick Jr. on his eponymous daytime talk show: "I was nervous I was proposing on set, but, really because, you know, my fiancée, we've been together for many years, and she knows all the Sharks. So I saw Kevin in the corner whispering to [Heather] about royalties and all kind of stuff when I proposed." 

Two years later, they tied the knot in an intimate ceremony in New York. Daymond is also a dad to two adult daughters, Yasmeen and Destiny, from his first marriage.

Croatian-born tech investor Robert Herjavec, 63, met his wife, the ballroom dancer Kym Johnson, 49, back in 2015 when he was partnered with her on Dancing with the Stars. While there was speculation at the time that his relationship with Kym had overlap with his ex-wife, Diane Plese, the Shark had ended his 24-year marriage in 2014.

Robert and Kym tied the knot in 2016 and two years later, they welcomed twins, a boy named Hudson and a girl named Haven.

"I never thought my heart could feel so full. We're so in love with our little angels," Kym wrote on Instagram after the twins were born. This wasn't Robert's first foray into fatherhood. He shares three kids – Skye, Brendan, and Caprice – with Diane.

The "Queen of QVC" Lori Greiner, 56, has been married to her husband Dan Greiner for 16 years. The two met at a Chicago bar in the 1990s. The two are more than just husband and wife, they are business partners.

Dan invested in Lori's first big invention –  a jewelry organizer. "He's cautious – not at all the type to push the envelope," the Shark wrote in her book Invent it, Sell it, Bank it!: Make Your Million-Dollar Idea into a Reality. "And yet, in this instance he was on board from the minute I told him about my idea."

To this day, the two still work together and have patented more than 100 products. According to Lori: "Dan is a numbers guy; I'm the inventor. That's why we're a perfect team."

Daniel Lubetzky was promoted to full-time Shark in 2024 after five years as guest Shark. The 57-year-old KIND LLC founder gained much of his wealth in 2020 after he sold his majority stake in the business to Mars for about $5 billion.

Outside of work, Daniel is married to Michelle Lynn Lieberman. The two tied the knot in 2008 and went on to welcome four children together. While there is not much known about Michelle, she is a nephrologist – a doctor specializing in kidney health – in Austin, Texas.
