Shark Tank’s Season 16 Episode 20 aired on 16th May 2025 and is sadly known as Mark Cuban’s last dance on the show. The episode featured the usual four pitches and an unusual, yet heartfelt farewell of the most magnanimous Shark, Mark Cuban.

The products featured on the episode included a tick-removal mitt, gourmet deviled eggs, seamless invisible underwear, and oversized luxury candles, all of which were vying for deals in the Tank.

Shark Tank Season 16 Episode 20 – The Shark Investors and Entrepreneurs

The range of products featured was very much in the spirit of the Tank, from undergarments that don’t show to candles that burn longer than most. The episode also featured never-before-seen business models of gourmet eggs.

Another standout product from the episode was Tick Mitt, which helps remove ticks for animals and humans in the most eco-friendly and human-friendly way possible.

Since it was both the season finale and Mark Cuban’s final episode, every pitch carried extra weight. Entrepreneurs knew landing him as a partner one last time would be unforgettable.

1. Tick Mitt

Tick Mitt opened the show by presenting a reusable microfiber mitt designed to catch and clear away ticks from pets, people, and clothing before they bite. The venture was led by Steve and Olivia Abrams, a father-daughter duo.

When Olivia was a kid growing up in upstate New York, she got really sick and was eventually diagnosed with Lyme disease. The experience stuck with the family, which led them to create Tick Mitt, a chemical-free mitt that swipes ticks off before they get the chance to bite.

The mitt can be tossed into the provided dryer bag and heated for ten minutes to kill any ticks it picks up.

During the pitch, Barbara Corcoran inquired about how a soft mitt could catch tiny ticks. Steve said they went through 13 prototypes to perfect the microfiber loops for ticks of all sizes.

Mick Tick’s cloth had microfiber loops built to trap ticks of different sizes. They also had a patent on their design, as mentioned by Olivia.

Mark Cuban asked how users could be sure Tick Mitt didn’t miss any ticks. Steve admitted it’s not foolproof but said it removes about 90–95% of loose ticks, which is far better than other options.

Steve also mentioned that their product was named Innovation Product of the Year at the Outdoor Retailer Trade Show. This opened a lot of avenues, as it brought them more than 70 retail chains that were interested.

They have generated $432,000 in sales since launch. Out of which $252,000 had come that year alone at the time of the pitch (May 2025). The company generated over $300,000 in revenue in 2024.

Mark and Daymond John passed on the deal, saying it wasn’t the right fit for them. Lori also declined because of a conflict with her investment in Bug Bite Thing.

Barbara Corcoran, who had a Lyme scare with her young son, offered $250,000 for 30% equity. The founders countered with 20%, but Barbara didn’t budge, and they couldn’t agree.

Kevin O’Leary then offered $250,000 for 20% equity plus a $1 royalty per unit until he recouped $2 million. Steve had no choice but to push back because the royalty would hurt distributor margins. Kevin stuck to his terms, to no avail.

In the end, Steve and Olivia left without a deal.

2. Stringys

Olivia Karina and Elvira Troger took the stage with Stringys on Season 16, Episode 20 of Shark Tank. Their product tackles a problem many women experience but few companies address—by few, we mean next to none.

Stringys makes women’s undergarments that stay in place and remain invisible under clothing. They use a unique bonded material that sets them apart from regular underwear. The company sells mainly online through a direct-to-consumer model.

In just 11 months, the brand generated $180,000 in revenue. Low production costs leave plenty of room for profit. The company also drew early investors and raised an additional $400,000 through a SAFE (Simple Agreement for Future Equity).

Lori Greiner kicked things off by asking about patents. Elvira said one was in progress and shared that it took over 60 prototypes to get the design right. Barbara Corcoran asked how they would use the desired $300,000.

Elvira once again elucidated that it would fund a larger inventory, as they frequently faced a stockout problem (green flag).

Kevin O’Leary had his usual patronizing tone towards the valuation, but still ended up making the first offer. He proposed $300,000 for 3% equity plus a $1 royalty per unit, with no end date.

Daymond John opted out because he did not agree with the valuation. Lori also stepped back, but she showed support for Kevin’s campaign. Mark Cuban also exited, saying he couldn’t contribute much in this niche.

Then Barbara came sweeping in. She offered $300,000 for 10% equity. The founders pushed back, saying a lower valuation would hurt them since their SAFE notes already convert at a discount. They countered with advisory shares and a smaller royalty.

Kevin was still in the talks and going head-to-head with Barbara. Kevin lowered his royalty to 50 cents, but Barbara plunged further. She suggested 3% equity and a 22-cent royalty per unit. Olivia and Elvira agreed after removing the advisory shares.

And with that, Stringys sealed a deal with Barbara.

Stringys’ net worth in 2025 is estimated to be between $3.3 million and $7.25 million. The brand gained momentum and popularity due to endorsements from A-listers like Emily Ratajkowski and Doja Cat.

3. Deviled Egg Co.

This is the first company in the world to focus on gourmet deviled eggs with flavors inspired by popular foods. The founder, Raechel Van Buskirk, launched the business after a series of kitchen experiments sparked her love for deviled eggs.

Barbara Corcoran showed curiosity and asked about the origins of the business. Raechel explained that the idea started in 2017 and took several years to fully develop.

Daymond John wanted to know where the company operates. Raechel said they’re based in Omaha and Denison, Texas. Barbara also questioned the move from a food trailer to a full restaurant.

Alexi further elucidated that the food truck was a test to gauge interest. Moving into restaurants didn’t yield strong profits, so they switched to a grab-and-go approach.

Lori Greiner wanted to know the numbers, especially of the generated revenue. Alexi reported growth from $60,000 in 2021 to $492,000 in 2023. For the year 2024, they generated $1.3 million in annual revenue.

Lori and Daymond bowed out first, saying they lacked food industry experience. Barbara was interested but wanted to know more about the growth plans. Raechel said they wanted to open two more grab-and-go stores, which required $150,000.

Mr. Wonderful offered $150,000 for 20 percent, prompting Barbara to counter with $150,000 for 15 percent.

Mark Cuban proposed teaming with Barbara, offering $250,000 for 20 percent. In the end, Mark and Barbara joined forces for an offer. Raechel and Alexi accepted $250,000 for 20 percent equity.

This was a special moment for Deviled Egg Co., as this was Mark Cuban’s last deal on the show.

4. Big Ass Luxuries

Trent teamed up with his wife Chloe and her twin sister Kelsey to tackle common candle problems. Their brand creates large, long-lasting candles with intense fragrances.

Trent and Chloe started Big Ass Luxuries in 2021 from their kitchen. They saw a gap in the market for oversized, natural candles that lasted longer and carried stronger scents and set out to capitalize on it. Their candle formula blends eco-friendly soy wax, coconut, and custom fragrance oils.

Once the business ball was rolling, sales were happening mostly through direct-to-consumer via Shopify. The D2C made up for 95% of sales and the remaining revenue came from retail. The company had $5 million in revenue by the end of 2024.

On the Tank, the founders asked for $500,000 in exchange for 5% equity. Daymond John liked the idea but bowed out early since he already owns a candle brand. Mark Cuban and Barbara Corcoran also passed as home decor wasn’t their cup of tea.

Lori Greiner was interested, but competitor pricing was a big concern. Kevin O’Leary’s ears perked up at the mention of the direct-to-consumer model. The founders explained that buying large candles from competitors would cost at least 50% more.

Lori offered $250,000 as a loan and the other $250,000 for 15% equity. This is when Kevin O’Leary stepped in with $500,000 for 20% equity. His prime motivation was rooted in using the brand for his gifting business.

Kevin’s offered deal did not stand, so the founders started negotiating with Lori instead. They countered Lori, asking her to cut equity to 10%. After some back-and-forth, she settled at 13%.

The deal closed at $500,000, with $250,000 as a loan and $250,000 for 13% equity.

Shark Tank Without Mark Cuban

Season 16’s finale felt like the end of a chapter. The pitches were strong, the deals were lively, but the spotlight belonged to Mark Cuban’s goodbye. The deals will go on, the pitches will keep coming, but fans will miss his presence.
