Buttercloth Men’s Shirts Update | Shark Tank Season 10

Danh Tran spent years designing clothes but hated how stiff and scratchy dress shirts always felt, especially after long hours at work. He came up with Buttercloth, a dress shirt that’s soft like a T-shirt but still looks clean and professional. Will the sharks get excited about what Buttercloth brings to the table? Let’s dive into our Buttercloth update and pitch recap to find out.

  • Ask:  $250,000 for 10% equity

Danh and his business partner, Gary, entered Shark Tank to pitch their ultra-soft dress shirt, Buttercloth.

Behind them, a sign read “the world’s most comfortable shirt,” setting the tone for their presentation.

Gary then explained that Buttercloth used 100% natural, sustainable, long fiber cotton.

To demonstrate the product’s quality, they brought in their “long-fiber cotton scientist,” Metta World Peace.

Metta wore a Buttercloth shirt, dunked a basketball, and highlighted that the shirts stayed breathable, stretchy, and professional-looking even during physical activity.

Following the demonstration, each shark received a sample tailored to their size. Robert Herjavec immediately complimented their strong business model.

Danh said the shirts sold for $98 to $118 and cost $20 to $25 to make. Gary clarified that this was the landed cost after shipping.

Buttercloth is sold exclusively online and marketed through Facebook and Instagram ads.

In the seven months leading up to their appearance on Shark Tank, they had generated $500,000 in sales.

To get the company to this point, Danh took significant personal risks. He liquidated his retirement fund, sold his house, and quit his job to invest $240,000 into Buttercloth.

However, not everything was perfect. Danh admitted their customer acquisition cost stood at $40 per customer, which raised concerns.

Robert asked how they planned to use the investment. Gary responded that two-thirds would fund inventory purchases, while the rest would boost marketing.

Kevin O’Leary pointed out that bringing down customer acquisition costs would be expensive. He didn’t see enough margin and went out.

Mark Cuban agreed with Kevin. He believed they should focus more on marketing rather than increasing inventory. He also decided not to invest.

Similarly, Lori Greiner exited next. She explained that she was already fully committed to her own clothing brand and didn’t want to stretch herself too thin.

Guest shark Charles Barkley followed. He admitted that he found the clothing industry too stressful and was unwilling to take on the risk, even with Metta’s support.

At this point, Robert decided to make them an offer of $250,000 for 25% equity. Danh hesitated and countered with 20% equity.

However, Robert stood firm. Eventually, Danh accepted Robert’s offer and looked genuinely happy with the outcome.

Let’s now take a closer look at our Buttercloth update and see how the company has performed since appearing on Shark Tank.

Shark Tank Buttercloth Update

Our Buttercloth update found that the deal with Robert Herjavec successfully closed after the company appeared on Shark Tank Season 10.

Following the episode, the brand saw a major boost in website traffic, sales, and social media engagement.

This exposure helped Buttercloth grow quickly, expanding beyond men’s shirts into women’s shirts, sweaters, and jackets.

In 2019, our Buttercloth update found that they introduced Icy Cotton, a patented fabric made with organic mint fibers designed for cooling comfort.

Metta World Peace continued to endorse the company, and Jay Leno became a brand ambassador in 2022, helping promote the Icy Cotton collection.

The company also launched the “Robert Herjavec Collection,” featuring styles curated by the shark himself. More recently, Buttercloth partnered with Steve Harvey.

At the time of this writing, Buttercloth has grown to around $5–6 million in annual revenue.

If you’d like to buy a shirt, you can find them on the Buttercloth website.
