Finding a comfortable, supportive bra is a struggle many women face, especially those with larger cup sizes. Most bras either dig into the skin, lack proper support, or are so uncomfortable that wearing them feels like a punishment. Athena Kasvikis knew this struggle firsthand. As a woman with a larger bust, she was tired of wearing multiple sports bras just to feel supported during physical activities.
This frustration led her to create Behave Bras, a line of wire-free, ultra-supportive bras designed specifically for women with cup sizes DD to I.
Athena appeared on Shark Tank Season 13, seeking $150,000 for 15% equity to grow her business. She impressed the sharks with her innovative Stayz technology, which provides better support than traditional underwire bras. While most sharks hesitated, Kevin O’Leary (Mr. Wonderful) made an immediate offer of $150,000 for 20% equity. After a brief negotiation, Athena accepted, securing a deal that would help expand her brand.
Since Shark Tank, Behave Bras has continued to grow. The company reached over $1 million in sales in 2022, appeared on QVC, and gained recognition from major media outlets. With a strong online presence and a loyal customer base, Behave Bras is proving that comfort and support can go hand in hand, even for larger cup sizes.

Athena Kasvikis Backstory + Their Initial Pitch
Athena Kasvikis didn’t set out to become a bra designer. Her journey began out of pure necessity. As an active woman with a larger bust, she struggled to find bras that offered real support without discomfort. Most bras either had painful underwires or lacked the structure needed to keep everything in place. Even sports bras weren’t enough—she often had to layer multiple bras just to feel secure while playing soccer.
Frustrated by the lack of options, Athena decided to create her own solution. She spent years researching fabrics, designs, and support structures. Her goal was simple: make a bra that was both supportive and comfortable enough to sleep in. After countless prototypes, she developed Stayz technology, a unique internal support system that replaces underwire while providing even better lift and shaping.
When she launched Behave Bras, she focused on direct-to-consumer sales through her website. This allowed her to maintain control over quality and customer experience. Within 18 months, she generated $110,000 in sales—a strong start for a self-funded business. She also filed for a patent to protect her innovative design.
During her Shark Tank pitch, Athena confidently explained her product’s benefits. She even demonstrated how the Stayz technology could be adjusted to change the bra’s silhouette. The sharks were impressed by the quality and the fact that Behave Bras had an exceptionally low return rate—a rare feat in the apparel industry.
Queries + Shark’s Responses, and Final Deal
The sharks had plenty of questions for Athena.
Kevin O’Leary was the first to show real interest. He loved the patent-pending technology and the fact that the bras had such a low return rate. Without waiting for others, he made an immediate offer of $150,000 for 20% equity. This surprised everyone, including Athena.
Mark Cuban was skeptical. He liked the product but wasn’t sure about the scalability. He worried about competing with big lingerie brands and decided to pass.
Lori Greiner, the “Queen of QVC,” saw potential but felt the valuation was too high. She also didn’t like that the company was still in its early stages. She chose not to invest.
Barbara Corcoran agreed with Lori. She thought the bras were well-made, but wasn’t convinced the business could grow fast enough. She also passed.
Daymond John, who has experience in the apparel industry, had concerns about manufacturing costs and profit margins. He didn’t make an offer.
Athena tried to negotiate with Kevin, asking if he would accept 17% equity instead of 20%. But Kevin refused, saying his offer was already fair. He emphasized that his expertise could help her scale the business efficiently.
After a short pause, Athena accepted Kevin’s deal. She knew his connections and business acumen could take Behave Bras to the next level.
