Shark Tank's judges have spent the past 11 years doling out fat checks, along with humorous punches and helpful advice to the founders who pitch them. This season, four new guest judges will join their ranks and potentially scoop up new investments

In an announcement on August 28, ABC revealed its newest slate of guest judges who will appear on Season 11 of Shark Tank, set to premiere on September 29. Stitch Fix founder Katrina Lake, Kind Snacks' founder Daniel Lubetzky, tennis star and Sugarpova founder Maria Sharapova, and 23andMe co-founder Anne Wojcicki will join two other guest judges who have appeared on previous seasons: RSE Ventures co-founder Matt Higgins and marketing expert Rohan Oza. You can also expect to see the show's regular Sharks, including Barbara Corcoran, Mark Cuban, Lori Greiner, Robert Herjavec, Daymond John, and Kevin O'Leary.

Here's what you need to know about the new cast of guest judges.

Katrina Lake

In 2011, the Harvard Business School graduate launched her personal shopping startup Stitch Fix, which sends customers clothing based on their style preferences and allows them to return what they don't want. Six years later, when she was 34, she took the company public as the youngest female founder to ever lead an IPO. The San Francisco-based company raised $120 million and she appeared at the Nasdaq platform holding her toddler. 

Stitch Fix, which has been profitable since 2014, has since expanded from selling womenswear to menswear, kids' clothing, plus sizes, and basic items like underwear. It generated $1.2 billion in its 2018 fiscal year and booked $366 million in the first quarter of this year. Lake is also on the board of directors for food delivery site Grubhub and e-commerce beauty site Glossier. 

Daniel Lubetzky

Lubetzky launched the New York City-based Kind Snacks in 2003 and has since built it into a snack-foods empire. Kind's snack bars are made from ingredients like fruits, nuts, and grains and come in a variety of forms, including ones made for children and others packed with extra protein. The company hasn't disclosed revenue figures since 2012, when it noted it booked $125 million in sales, but told Inc. in 2015 that revenue has doubled every year since its founding. 

Lubetzky invested $3 million in 2015 in three women-led food companies: seaweed snack startup GimMe Health Foods, popcorn maker 479 Degrees, and fruit and veggie ice pop business EatPops, which has since shut down. He's also invested in healthy jerky startup Krave and nut butter maker Justin's. 

Maria Sharapova

Perhaps more widely known for winning tennis matches, the 32-year-old Russian athlete is also the founder of the Coral Gables, Florida-based candy company Sugarpova. Growing up, her father would treat her to a chocolate bar or lollipop after a long day of practice, not only encouraging her sweet tooth but giving her inspiration for her first business. She launched Sugarpova in 2012, with her longtime agent Max Eisenbud, who serves as the chief executive. Sugarpova's current revenue is unknown, as the company did not respond to Inc.'s information request prior to publication. However, in 2016, Eisenbud revealed to Forbes that the company expected revenue to reach $20 million by 2018, the year it released its chocolate line.

Sugarpova's offerings include chocolate truffles, sour gummies, and gumballs in the shape of tennis balls and are sold in 22 countries through its website and multiple retailers. In 2014, Sharapova became a co-owner and invested an undisclosed amount in the SPF-protected beauty product line Supergoop, noting that her job demands time in the sun and she was a fan of the products before joining the team. 

Anne Wojcicki

Wojcicki left her career in biotech investing in 2006 to found 23andMe, an at-home genetics and health test kit. Since then, the Mountain View, California, company has won U.S. Food and Drug Administration approval to test consumers' predispositions for diseases like Alzheimer's, Parkinson's, and a variety of cancers. The company is now one of the biggest players in the genetics testing industry, with more than five million customers taking its ancestry and health tests. Additionally, it was reportedly valued at $1.75 billion during a $250 million fundraising round in 2017.

The saliva-testing company booked an estimated $475 million in revenue last year, according to Forbes, but still isn't profitable. The company declined to comment on its annual revenue.

Correction: An earlier version of this story misidentified the type of testing 23andMe conducts.
