Zach Dunn never set out to sell hats. He grew up in a one-stoplight town in rural Georgia, in a family of farmers and entrepreneurs who were never afraid to take a leap of faith and try different ventures.
In his early 20s, about a decade ago, he and his father walked into a bank with a business plan and walked out with a $250,000 loan to start a farm.
鈥淭hat was my experience with starting from the concept of an idea and then bringing it to reality,鈥 Dunn tells 麻豆社 in a new interview.
They farmed cotton and tobacco and did well for a year or two, until one bad year wiped them out and left Dunn in 鈥渁 heap of debt鈥 that he still had to repay. 鈥淚 learned not to grow too fast, to take my time and really think through my decisions,鈥 Dunn says.

He had dropped out of college to start the farm. After the farm collapsed, Dunn went back to school as a business major and sold cars on the side. He worked his way up in car sales, eventually becoming a general manager and then a finance manager at a dealership. He and his future cofounder and college roommate, Chason Rabitaille, were both selling cars and studying when they started seeing Facebook ads for hat companies. 鈥淲e realized that we could also do that,鈥 Dunn recalls.聽
The two started in April 2020 in a spare bedroom, with Dunn putting his entire life savings on the line: $15,000. 鈥淲e bought 15 different hat colors, 40 patches and an industrial sewing machine, and that鈥檚 how we started,鈥 he says. In the beginning, it was just the two of them, with Rabitaille actually sewing and finishing hats in-house, a made-to-order model the company still uses.

Learning to go viral on purpose
Mad Hatter鈥檚 early growth came from Facebook and Instagram ads, especially for vintage-style patch hats. Then Apple鈥檚 iOS 14 privacy changes hit, and ads became 鈥渁 lot less profitable,鈥 Dunn explains. The brand was in 鈥渁 weird position鈥 as it was still figuring out its identity and how to attract customers.
Dunn responded by shifting away from paid advertising and doubling down on organic content. He bet that if the company could consistently go viral, customers would flood its Shopify site.
They focused first on Instagram, learning through painful trial and error. Over time, Dunn says, 鈥渨e learned how to become viral.鈥 The company later realized that attention and cultural conversation were moving to TikTok, so they launched a TikTok page.
The Mad Hatter formula for going viral
For Dunn, virality starts with the product, not the algorithm. 鈥淚t has to be something people really want or something that people connect with or resonate with,鈥 he says.
From there, his team layers in TikTok-optimized essentials: the right audio and sharp captions. They are constantly experimenting with short-form video. 鈥淚t鈥檚 a whole puzzle,鈥 he says. 鈥淲e can鈥檛 just say, ‘Hey, I want to go viral tonight,’ but over time, we definitely will go viral. It鈥檚 just a matter of time.鈥
Dunn says all of these skills are self-taught. He credits years of posting, making mistakes and adapting to platform changes with Mad Hatter鈥檚 virality.
The company鈥檚 real turning point came when Dunn stopped chasing what everyone else was doing. Early on, he wanted to look like other outdoorsy brands, but realized that the market was saturated with deer, bass and athletic logos. Dunn decided to take a different approach with humorous 鈥渨ord track鈥 hats 鈥 simple, culturally-tuned phrases like 鈥淢ama Tried鈥 or 鈥淧ut It On My Husband鈥檚 Tab.鈥
鈥淣obody was doing what we were doing with the funny hats,鈥 Dunn recalls, noting that humorous hats have always existed, but 鈥渘obody was on social media pushing them.鈥
鈥淲e went from following trends to setting them,鈥 he says.
TikTok Shop as a growth engine
By the time TikTok Shop launched in 2023, Mad Hatter had already built an affiliate network and a habit of repetitive short-form posting. When TikTok rolled out its commerce tools, those efforts 鈥渁mplified everything to another level.鈥 Today, Dunn estimates that TikTok Shop is 鈥減robably 65% of our revenue.”
The company leans into affiliates, live selling and ads, embracing almost anything the platform prioritizes in order to stay aligned with its goals. 鈥淚f you do a lot of the little things TikTok wants, these little moments create these major moments,鈥 Dunn says. Mad Hatter is up more than 100% year over year on TikTok, and the growth has triggered real operational growing pains, from production to shipping to customer service.
Mad Hatter now operates out of a 10,000-square-foot warehouse where every hat is finished to order within 24 to 72 hours. 鈥淲e鈥檙e built for TikTok; we鈥檙e built for virality,鈥 Dunn says. Unlike brands that go out of stock during a viral moment and wait 90 days for factory restocks, Mad Hatter holds blank stock and decorates in-house, allowing the team to 鈥渕ake to demand鈥 and fully monetize spikes in attention.
The company has also expanded into clothing, which now represents about half of the business, and Dunn does not see a ceiling on where the brand can go. In five years, he hopes to be in a much larger, more efficient facility, with a community that is 鈥10 times bigger.鈥
Advice for other founders
Despite rapid growth and projected eight-figure revenue this year, Dunn has no interest in scaling at any cost. He advises other founders to chase profitability, not the biggest revenue number possible.
鈥Profitability is super important,鈥 he says, adding that chasing top-line vanity metrics can become a trap where 鈥測ou鈥檙e almost not making money because you want that top line to be so big. Don鈥檛 chase that rabbit down the hole.鈥
Dunn knows firsthand how easy it is to fall into that trap. When he looked at the books last year, he realized that the company was 鈥渂arely breaking even.鈥 In response, Mad Hatter stopped discounting its hats on TikTok, raised discipline around pricing and returned to health this year. Dunn also emphasizes that buying a Mad Hatter hat supports a growing team of roughly 40 to 45 employees across Georgia and Mississippi, many of whom rely on the company for their livelihood.
鈥淲e鈥檙e a small business; we鈥檙e the underdog, and I think our hats represent the underdog in a way,鈥 he says.
