In this exploration, we delve into the pivotal moments, successes, and lessons learned by Rounderbum since its Shark Tank debut, uncovering the impact of the strategic alliance forged in the tank.

What Is Rounderbum:

Rounderbum is a men’s undergarment company that has revolutionized the industry with its innovative shapewear technology [1]. Rounderbum’s primary focus is to enhance men’s physical appearance. The brand offers a range of padded products designed to give men more rounded and fuller-looking buttocks. This concept is innovative, going against the grain of traditional men’s underwear.

One of the most significant advantages of Rounderbum underwear is the fit. Numerous reviews highlight the snug and comfortable fit of the product. This makes them an excellent option for men who dislike loose underwear.

The Unique Concept

Specializing in crafting underwear that accentuates individual attributes, Rounderbum focuses on giving men’s bottoms a more rounded and enhanced appearance. The undergarments from Rounderbum incorporate a plethora of cutting-edge technologies.

What Is Rounderbum

Among these innovations is compression technology, providing essential support and a flattering slimming effect. Gravity technology ensures a liberating descent for the package, while package technology adds volume to a man’s intimate areas. Additionally, lift technology incorporates bands that uplift saggy bums, and padding technology introduces extra pads to the underwear, contributing to a fuller and rounder look.


Innovative Padded Technology:

Rounderbum’s standout feature is its Padded Technology, aimed at providing a discreet and subtle muscle-enhancing effect. This innovation caters to individuals who desire a more athletic and attractive appearance. The garments are meticulously designed to conform to various body shapes, offering a personalized fit that boosts confidence.

Confidence-Boosting Design:

The primary objective of Rounderbum is to make every man feel and look more confident. By combining seamless design with muscle-lifting and defining technologies, the undergarments contribute to a positive self-image. The garments not only focus on aesthetics but also prioritize comfort, creating a comprehensive package for consumers.

Diverse Product Range:

Rounderbum goes beyond padded briefs, offering a diverse product range that includes shirts, trunks, and boxers. This diversity allows customers to choose from various styles and preferences, making Rounderbum a one-stop shop for body-enhancing undergarments.

Online Presence and Sales Growth:

The decision to launch Rounderbum as an online-only brand proved to be a strategic move. Leveraging social media and Facebook ads, the company quickly gained traction. By 2017, Rounderbum had achieved an impressive milestone, surpassing $ 1 million in sales through its online platform. This success underscores the effectiveness of their digital marketing strategy.

Entrepreneurial Origin Story:

Jonathan Diersing’s journey from a neuroscience graduate with aspirations of becoming a doctor to the founder of Rounderbum adds a compelling narrative to the brand. The unexpected pivot into entrepreneurship, driven by the desire to create confidence-boosting products, reflects the spirit of innovation and determination that defines Rounderbum.

Shark Tank Appearance:

The exposure on this popular entrepreneurial show provided the brand with a platform to showcase its products and vision. The episode, which aired on January 21, 2018, marked a significant moment in Rounderbum’s trajectory.


Niche Market Appeal:

While Rounderbum’s focus on body-enhancing undergarments is a unique selling proposition, it also means that the brand caters to a niche market. The appeal may be limited to individuals specifically seeking such enhancements, potentially excluding a broader customer base.

Price Range:

The price range of Rounderbum’s products, ranging from $ 20 to $ 29 for briefs, may be perceived as relatively high for some consumers. While the innovative technologies and design justify the cost, it could be a barrier for price-sensitive customers.

Limited Retail Presence:

As of 2023, Rounderbum primarily operates online. While this model has proven successful, it limits the accessibility of the products for customers who prefer in-store shopping or those who wish to try on garments before purchasing.

Potential Product Understanding Challenge:

The innovative technologies used by Rounderbum, such as Padded Technology, may require a clear understanding by consumers. Communicating the benefits effectively and dispelling any misconceptions about the purpose of the enhancements could be a potential challenge [2].

About the Founders Of Rounderbum

Jonathan Diersing stands as the driving force behind Rounderbum, the brand he founded with a commitment to excellence [4]. In 2015, Diersing strategically entered into a licensing and manufacturing collaboration with the esteemed Mexican company Round Wear, recognized for producing undergarments under various brand names. This collaboration marked the inception of Rounderbum’s journey into crafting premium undergarments. 

The initial focus was on the production of boxers and briefs tailored not only for men but also extended to include panties designed for women. Demonstrating versatility, Diersing further diversified the product line by introducing compression shirts for men and compression socks, enriching the brand’s offerings with a broader range of choices.

In a bid to enhance accessibility, Rounderbum’s meticulously crafted products found their way onto major online platforms like Amazon and selected small mom-and-pop shops. While acknowledging that the products might come with a premium price tag, Diersing’s unwavering commitment to quality ensures that Rounderbum’s offerings deliver exceptional results.

About the Founders Of Rounderbum

Recognizing the potential for expansion, Diersing strategically positioned Rounderbum for growth beyond online markets. In pursuit of this vision, he sought assistance from the seasoned investors on Shark Tank. His aim was clear – to secure a partnership that would not only provide the necessary support but also facilitate the brand’s expansion into a wider array of retail stores, ushering in a new chapter for Rounderbum.

The Pitch Of Rounderbum At Shark Tank

In the Shark Tank arena, Jonathan, the founder of Rounderbum, introduces himself and swiftly puts forth his funding request. Seeking $ 150,000 in exchange for a 10% stake in his company, he sets the stage for his pitch by emphasizing the importance of self-confidence [5]. Acknowledging the universal desire to “look good and feel good,” he engages the sharks with a rhetorical question about the common struggle with ill-fitting jeans, humorously demonstrated by a model beside him.

Positioning Rounderbum as a pioneer in body-shaping technology, Jonathan describes it as a brand that is “redefining the underwear market”. He details the various technologies integrated into their products, emphasizing their commitment to helping wearers feel confident. From traditional compression shapewear to innovations enhancing desired areas of the body, Rounderbum aims to provide a comprehensive solution.

The founder directs the sharks’ attention to his model, showcasing the padded trunks and muscle shirts for comfort and discretion. He underlines the invisibility of the products and their natural feel. The “before and after” visuals, coupled with product samples, further illustrate the transformative impact of Rounderbum’s offerings.

Sharks inquire about the motivation behind wanting a bigger butt, and Jonathan explains it aligns with the desire to look better. Addressing a comparison with Spanx for Men, he highlights Rounderbum’s focus on shaping rather than compression. The question of price arises, and the founder confidently states their $ 25 pricing is competitive.

Revealing impressive sales figures, Jonathan shares that Rounderbum achieved $ 1 million in sales since its 2015 website launch, with $ 700,000 in the past twelve months. All sales have been online, primarily driven by Facebook ads. The profitability stands at 25% to 30%, with a confirmation of $ 200,000 in the previous year.

The Pitch Of Rounderbum At Shark Tank

Jonathan outlines his need for $ 150,000 to hire a marketing team, invest in viral videos, and expand Facebook advertising. He mentions a new brick-and-mortar store in West Hollywood as part of a strategy to reduce fulfillment costs. Despite skepticism from the sharks regarding the cost-effectiveness of a physical store, Jonathan anticipates $ 1 million in sales for the year, aiming for $ 1.5 million the following year.

Daymond questions the urgency of rapid growth, prompting Jonathan to reveal his non-business background and initial pursuit of medicine due to his mother’s multiple sclerosis. His shift to sales eventually led to the creation of Rounderbum. Impressed yet finding it challenging to understand the product, Daymond withdraws. Mark expresses doubts and drops out.

Kevin, acknowledging Jonathan’s achievements, offers $ 150,000 for a 5% stake with a $ 2 royalty until $ 300,000 is recouped. Jonathan seeks assurance for major retail placement, and Kevin affirms. Mark, Lori, and Robert subsequently drop out. Jonathan turns to Robert for a counteroffer, but Robert offers $ 150,000 for 20% equity.

Negotiating unsuccessfully for 15%, Jonathan ultimately agrees to Kevin’s offer, sealing the deal for a 5% stake and a $ 2 royalty until $ 300,000 is fulfilled. The episode concludes with a handshake and hug between Jonathan and Kevin.

Rounderbum After The Shark Tank

Following the show, the deal brokered between Kevin and Rounderbum materialized, marking a significant milestone in the brand’s journey. The exposure on Shark Tank played a pivotal role in generating public interest in Rounderbum, propelling it into the spotlight. Kevin O’Leary, serving as a staunch supporter of Jonathan, not only assisted in brand building and marketing but also leveraged his influential social platforms to promote Rounderbum.

Kevin’s endorsement added a compelling dimension to Rounderbum’s marketing strategy. He openly shared his switch from his old underwear to Rounderbum, becoming a strong influencer in attracting customers. This testimonial not only reflected Kevin’s confidence in the brand but also served as a powerful endorsement for potential customers.

During the pitch, Rounderbum had initially presented a valuation of $ 1,000,000. However, the deal selected by Jonathan resulted in a reevaluation, elevating the company’s worth to $ 3,000,000, accompanied by a $ 2 royalty until $ 300,000 was recouped. This strategic decision showcased Jonathan’s negotiation acumen and set the stage for Rounderbum’s post-show success.

The post-show journey was marked by significant achievements and growth for Rounderbum, attributed to the invaluable expertise and support provided by Kevin O’Leary. The collaboration extended beyond Shark Tank, with Rounderbum making appearances on various popular shows. Notably, their most significant sale occurred on Aftermath, and the brand secured the fourth position on the best-selling underwear list on Amazon, a testament to their growing popularity.

Rounderbum, positioned at the intersection of muscle-focused apparel, t-shirts, and underwear, offers products in the price range of $ 35 to $ 42, as stated on its official website [6]. The brand introduced new additions, including the Stelaeath lift trunk priced at $ 35 and the Chromatic lift boxer at $ 29. To incentivize customers, Rounderbum provides a 10% discount on the first purchase made through its website, enhancing the appeal for potential buyers.

Rounderbum continues to thrive in the market, showcasing sustained success. The brand achieved its most significant sale during the Aftermath show and currently holds a notable position as the fourth-best-selling underwear on Amazon. Additionally, Rounderbum has expanded its product offerings with a few innovative additions.

The brand’s commitment to innovation, marketing, and strategic partnerships has propelled it into the forefront of the men’s undergarment market, marking Rounderbum as a notable success story in the business world.
