First into the tank is Jonathan Diersing of Rounderbum, seeking $150,000 for 10 percent equity.

Key Takeaways:

  • Product: Men’s body-enhancing underwear to boost confidence.
  • Investment Ask: $150,000 for 10% equity.
  • Shark Response: Kevin O’Leary offered $150,000 for a $2 per unit royalty until $300,000 is recouped, plus 5% equity, which was accepted.
  • Post-Show Success: Rounderbum has grown its customer base and expanded its product line, continuing to sell successfully in the men’s fashion market.
  • Latest Update: Rounderbum continues to thrive, offering a variety of body-enhancing undergarments for men and expanding into new retail markets. The brand’s unique value proposition continues to attract a dedicated following.

Latest Update:

Rounderbum is a line of men’s underwear that features “body enhancing” elements. According to their website, their “commitment is to make garments that make every man feel and look better, more masculine and confident” with shaping undergarments. The products include “padded,” “package” and “lift” technologies, which add volume and definition to the buttocks. A variety of styles, colors and accessories are available, in addition to anatomic and compression options.

In the last year, they have done $700,000 in sales. With an investment from a shark, Diersing hopes to hire a marketing team to create viral videos. They are projected to do $1 million this year.

What Did the Sharks Think About the Pitch

Daymond John doesn’t understand the “enhancing” clothing and goes out. Kevin O’Leary, however, likes the business and offers $150,000 with a $2 royalty until $300,000 is recouped with five percent equity. Since Mark Cuban goes “commando,” he goes out followed by Lori Greiner.

Robert Herjavec likes the product and offers $150,000 for 20 percent. Diersing counters 15 percent, which Herjavec declines. He counters again at $300,000 for 20 percent, which he declines.

Ultimately, he accepts O’Leary’s offer.
