Sliimey Honey, a unique slime business founded by Mark Lin in 2018, gained popularity for its scented and creatively designed slimes. Each slime was designed to resemble various foods, and they were packaged in small plastic cups. The business was initially established on Etsy, where it garnered a positive response. However, Mark had bigger aspirations which led him to appear on Shark Tank in Season 14, Episode 8.

Sliimey Honey’s Offer on Shark Tank
When Mark Lin entered the Shark Tank, he was seeking a $150,000 investment in exchange for a 10% equity stake in Sliimey Honey, valuing the company at $1.5 million. Mark presented his slime products to the sharks, emphasizing their unique scents and designs.
The pitch highlighted that the slimes could be sticky and deflated, but with the addition of a special activator (a mixture of warm water and Borax), they regained their sticky texture. Slime ingredients included glue, Borax, scents, and essential oils. For added texture, items like bubble pop were incorporated, providing a satisfying crunch when played with.
Mark also shared that they used various scents in their different slime products, making them smell delightful. However, he emphasized that these slimes were not edible and should be kept away from children, pets, and surfaces such as clothes and furniture. Those with allergies to glue, Borax, fragrance oil, or food colouring were cautioned against using the product.
Sliimey Honey’s slimes were priced between $10 to $15 and were exclusively available through the company’s website. While their products could not be found on Amazon, the website offered a variety of different slimes.
Mark Lin: The Entrepreneur Behind Sliimey Honey
Mark Lin was not your typical entrepreneur when he started Sliimey Honey; he was a teenager with a passion for creating and selling slimes. In 2018, Mark launched the business while still in his teenage years, initially selling his products on Etsy. Over time, he transitioned to his own e-commerce website, and his savvy marketing strategies on social media platforms like Instagram and TikTok helped him gain a substantial following.
Mark would upload videos showcasing his slime products on Instagram and TikTok, and many of these videos went viral. His “sliimeyhoneyshop” TikTok account accumulated over 900,000 followers, and his Instagram account had more than 69,000 followers. Mark’s slime products were shipped worldwide, although customers had to wait approximately two months for their orders. The business had a no-refund and no-cancellation policy once a product was sold.
To manage the growing demand, Mark enlisted the help of about 11 of his high school friends. They worked diligently to package and ship products from Monday to Friday. The cost of making one slime ranged from $2 to $4, and the shipping cost for a single slime was between $5 to $6.
Sliimey Honey’s Impressive Sales and Profits
Sliimey Honey’s sales were nothing short of remarkable for a business run by a teenager. By the time Mark Lin appeared on Shark Tank, the company had achieved lifetime sales of $1.2 million.

In 2020, they recorded $50,000 in sales, resulting in a profit of $13,000. The following year, in 2021, sales surged to $580,000, with profits reaching $300,000.

Shark Tank Offers and Negotiations
The sharks evaluated Mark’s business proposition and made their offers. Daniel Lubetzky felt that the slime business wasn’t aligned with his expertise and opted out. Kevin O’Leary extended an offer of $150,000 in exchange for a 30% equity stake in Sliimey Honey.
Lori Greiner expressed her admiration for the slime business but ultimately decided it wasn’t the right fit for her and declined to invest. Mark Cuban believed in the potential of the business but advised against taking an investment at that moment. Consequently, he chose not to invest.
Daymond John offered $150,000 for a 25% equity stake in the business, which prompted a counteroffer from Mark Lin. He proposed $300,000 for a 25% equity stake, which Daymond John declined.
