As mentioned, Nana Hats was founded by Sean Adler. Sean Adler had always been inclined toward creating something unique, and his idea for Nana Hats stemmed from a humorous observation about a common household issue: the rapid ripening of bananas.
While Nana Hats is the very first big venture that Adler set out to explore, he previously worked in product development, which further helped him shape his career as an entrepreneur.
Sometimes, the simplest ideas make the most impact and that’s exactly what Adler achieved with Nana Hats.
Nana Hats was founded on a simple yet effective idea: slowing down the ripening process of bananas. Adler’s idea was to design a product that could effectively reduce the release of Ethylene gas to prevent the quicker ripening of the banana.
The result was Nana Hats — a silicone cap that fits over the top of a bunch of bananas. These caps come with tiny, replaceable hats (such as those resembling animals, sports items, and other fun designs) that cover the silicone base.
Nana Hats works by attaching a small, reusable disc to the banana stem, which is designed to limit the amount of ethylene gas exposure and extend the bananas’ freshness by a few days.
Nana Hats gained significant attention when Sean Adler appeared on ABC’s Shark Tank during Season 14. Sean pitched his idea to the panel of investors where he asked for $150,000 in exchange for 10% equity in Nana Hats, valuing the company at $1.5 million.
One of the Sharks, Mark Cuban, was particularly intrigued by the combination of the product’s functionality and fun factor. After some negotiation, Adler struck a deal with Cuban, securing the $150,000 investment for a slightly higher equity share.
The Shark Tank appearance was a turning point for Nana Hats. The exposure from the show, coupled with the investment from Mark Cuban, allowed the company to grow rapidly. After the episode aired, Nana Hats experienced a spike in sales, with many viewers purchasing the product out of curiosity and for its practical use in preserving bananas.
Not just that, Adler’s partnership with Cuban opened up a network of opportunities, further helping him promote his product and gain more traction. Now, Nana Hats is available on major online platforms like Amazon and physical stores.
Yes, Nana Hats is still in business and continues to grow. Following the boost from Shark Tank, the company has maintained a steady presence in the market. Nana Hats has expanded its product line to include new designs and accessories, catering to different customer preferences. As of 2024, it is said that the company’s current valuation is at $2 million.
