GOB Shark Tank Update: Is It Still in Business?

Step into any massive stadium concert, a high-intensity spin class, or a bustling city street, and you are immediately hit by a wall of sound. For decades, the solution to protecting our hearing was simple: stuff a cheap, brightly colored piece of petroleum-based foam into our ears. But an estimated 40 billion plastic earplugs are produced and thrown away every single year, ending up in landfills where they will sit for centuries.

Enter Lauryn Menard, an ambitious material innovator who walked onto the Shark Tank stage in Season 17 with an utterly wild proposition. She wanted to replace the global supply of foam earplugs with lab-grown mushroom roots.

The pitch immediately sparked a fiery debate among the Sharks regarding the true definition of an earplug, and it highlighted the massive divide between creating a sustainable product and marketing it to the masses. Did the billionaire investors see the multi-million dollar potential in compostable hearing protection, or did the pitch fall completely on deaf ears?

What is GOB?

GOB (stylized as GOB Earth) is a sustainable wellness brand that has created the world’s first 100% home-compostable, bioengineered earplug. Instead of utilizing traditional polyurethane foam or silicone, GOB earplugs are manufactured entirely out of mycelium, the fibrous, vegetative root structure of mushrooms.

Unlike heavy-duty industrial earplugs designed to block out the world completely, GOB is engineered for acoustic fidelity. The squishy, cylindrical earplugs offer frequency protection ranging from 12 to 25 decibels. This means they are specifically designed to filter and dampen dangerous noise levels while still allowing the wearer to hear music, conversations, or instructions with perfect clarity.

The target audience includes concertgoers, musicians, neurodivergent individuals experiencing sensory overload, and anyone navigating a noisy environment who doesn't want to feel completely isolated. Once the earplugs have reached the end of their usable lifecycle, they can be tossed directly into a backyard compost bin or a garden bed, where they will safely decompose, leaving zero microplastics behind.

Who is the Founder of GOB?

The visionary behind GOB is Lauryn Menard, a San Francisco-based designer, material innovator, and sustainability expert. Prior to launching GOB, Menard built a formidable career working at the intersection of product innovation and circular economics, consulting for massive global retail brands like Target and Herman Miller.

The genesis for GOB was deeply personal. Menard watched her mother suffer from hearing loss, a difficult life change that forced Lauryn to closely examine her own hearing health. Her fiancé is also a musician who frequently plays in loud bands, placing both of them in environments where decibel levels routinely spike into dangerous territory.

Menard quickly realized that the existing market for earplugs was flawed. Traditional foam plugs muffled sound so badly that enjoying a live show became impossible, while high-end, custom-molded silicone plugs were prohibitively expensive and incredibly easy to lose. Furthermore, her background in sustainable design made her acutely aware of the horrific environmental impact of disposable foam.

Spending months locked in research and development, Menard began experimenting with bio-based materials. She eventually discovered that mycelium possessed the exact acoustic dampening properties and squishy tactile feel necessary for a functional earplug. By 2023, she co-founded GOB Earth Inc., determined to prove that sustainable "single-use" products didn't have to sacrifice performance.

GOB Shark Tank Journey & Pitch

In Season 17, Episode 14 (aired in the Spring of 2026), Menard stepped onto the Shark Tank carpet to face a panel featuring Kevin O'Leary, Lori Greiner, Fawn Weaver, Daniel Lubetzky, and Robert Herjavec.

Walking out with high energy and a touch of humor, Menard laid out the environmental catastrophe of single-use plastics and unveiled her mycelium solution. The Sharks initially chuckled at the idea of putting mushrooms in their ears, but they were intrigued by the sustainability angle. She demonstrated how the earplugs easily conform to the ear canal and handed out samples.

Then came the numbers. Menard revealed that the earplugs cost a staggeringly low $0.10 to manufacture, yielding incredible margins on her $9.95 to $24.95 retail packs. Better yet, without spending a single dollar on paid advertising, GOB had generated $40,000 in organic sales within its first two months of launching. She also dropped a massive hint about B2B growth, mentioning a burgeoning partnership with a massive live entertainment company that could easily push the brand into an eight-figure revenue bracket.

However, the pitch quickly derailed when the Sharks actually tested the product. Fawn Weaver, who relies on earplugs to sleep, noted that she could still hear Menard talking clearly. Lori Greiner echoed the sentiment, stating that a good earplug should deliver complete silence. Menard attempted to pivot, explaining the acoustic engineering behind the 12-25 dB reduction, emphasizing that they were designed to let certain frequencies through so concertgoers could still enjoy the music.

The investors fundamentally disagreed with this market positioning. Daniel Lubetzky praised the environmental mission but bluntly stated he didn't like the product, feeling the branding and benefits were too confusing for the average consumer. Robert Herjavec found the physical texture of the mycelium "very weird" and dropped out. Fawn Weaver and Lori Greiner followed suit, unable to get past the fact that the plugs didn't block out all sound.

Finally, Kevin "Mr. Wonderful" O'Leary took aim at the valuation. Menard was asking for $250,000 in exchange for just 5% of her company, implying a massive $5 million valuation. O'Leary argued that the valuation was entirely unproven for a company that had only been selling for two months, especially in a market flooded with cheap alternatives. Holding her ground on the value of her patented bio-material and upcoming B2B contracts, Menard refused to back down, leaving the Tank without a deal.

What Happened to GOB After Shark Tank?

Walking away empty-handed from Shark Tank is often a death knell for young startups, but for GOB, it simply served as a massive, free commercial. The "Shark Tank Effect" triggered a tremendous spike in website traffic immediately following the broadcast.

Viewers who frequently attend music festivals, work in noisy hospitality environments, or suffer from sensory processing disorders flooded the company's social media, deeply validating Menard's argument that not everyone wants an earplug that induces total deafness.

Post-show, Menard aggressively leaned into her B2B strategy. While the Sharks struggled to understand the direct-to-consumer appeal, event organizers immediately saw the value. Venue operators are constantly looking for ways to improve the guest experience and reduce the massive cleanup costs associated with plastic waste.

By the time their episode aired, GOB had already proven the Sharks wrong on several fronts. They had officially partnered with AEG Live and Bowery Presents. GOB earplugs were now stocked at massive US concert venues, including Forest Hills Stadium in New York and Under the K Bridge in Brooklyn. This strategic move placed the product exactly where the target demographic needed it most, at the point of sale just before the opening act took the stage.

What is the Valuation & Net Worth of GOB?

Because GOB Earth Inc. remains a privately held company and did not secure a heavily publicized venture capital round on national television, an exact 2026 revenue figure is not publicly disclosed. However, we can extrapolate based on the facts provided during the Shark Tank pitch and their subsequent growth.

Menard walked into the Tank demanding a $5 million valuation based purely on a $40,000, two-month proof-of-concept and pending venue contracts. While Kevin O'Leary laughed at that figure, the successful execution of her AEG Live and Bowery Presents partnerships likely means that valuation is no longer a stretch.

With manufacturing costs sitting at just $0.10 per unit and retail prices hitting up to $24.95 per pack, GOB enjoys astronomical profit margins rarely seen in consumer goods.

Industry analysts estimate that with their current venue penetration and direct-to-consumer digital sales, GOB's current 2026 valuation sits comfortably between $3 million and $5 million. The estimated net worth of the business is growing rapidly as they transition from a niche internet brand into a staple amenity at major American concert halls.

Where to Buy GOB Earplugs in 2026?

If you are looking to ditch the plastic and try out mycelium for yourself, the easiest place to purchase GOB earplugs is directly through their official website at gob.earth. They offer several purchasing tiers, from a 4-pair "Quad Pack" for $9.95 to a 12-pair "Core Pack" for $24.95. Shipping is available throughout the United States.

Additionally, if you frequently attend live music events, you can now purchase GOB earplugs directly at the merchandise or concession stands of several major US concert venues affiliated with AEG Live and Bowery Presents.

Are GOB Earplugs Reviews Good?

The reviews for GOB are highly polarizing, precisely reflecting the debate that occurred inside the Shark Tank. Customers who purchase the product expecting traditional, total-silence earplugs for sleeping next to a snoring partner frequently leave lower ratings, noting that the 12-25 decibel reduction is not enough to block out sharp noises.

Conversely, the reviews from live music fans, bartenders, construction workers, and neurodivergent users are overwhelmingly positive. These demographics consistently praise the earplugs for their comfort, noting that the squishy mycelium does not cause the painful inner-ear pressure associated with expanding foam.

They also rave about the acoustic fidelity, confirming that the earplugs successfully eliminate the painful ringing in the ears after a heavy metal concert without ruining the sound mixing of the band.

GOB Earplugs Alternatives

While GOB holds a unique monopoly on the home-compostable, mushroom-root market, they face steep competition in the acoustic filtering space.

• Vibes: Another Shark Tank alum, Vibes offers high-fidelity earplugs designed specifically for live music. However, Vibes are made from synthetic plastics and silicone, entirely lacking the environmental benefits of GOB.
• Loop Earplugs: Currently dominating the social media market, Loop offers stylish, ring-shaped silicone earplugs that provide varying levels of decibel reduction. While highly fashionable and reusable, they are significantly more expensive upfront and are not biodegradable.
• Eargasm: A heavyweight in the festival scene, Eargasm provides excellent acoustic filtering using silicone and metallic filters. Like Loop and Vibes, they are entirely reliant on traditional, non-sustainable manufacturing materials.
