Mammoth Brands Upcoming IPO: CPG group behind Harry's could go public in H2 2026

If at first you don't go public… rebrand, make an acquisition and try, try again? That seems to be the case for Mammoth Brands.

In March 2024, under its former name Harry's (parent company of the eponymous razor/personal care brand), the company reportedly confidentially filed for an IPO.³

A little over a year later, Harry's rebranded as Mammoth Brands, reflecting how the company has been growing and its ambitions evolving from just the Harry's brand to several other CPG brands (particularly personal care ones) through a mix of internal development and acquisitions.²

Around the time of the rebrand, co-founder Andy Katz-Mayfield told the New York Times that an IPO was likely someday, but the company wasn't in a rush. The Times also noted that he said "the company was profitable and could finance its growth."⁵

A few months after that, in October 2025, Mammoth Brands reached a deal to acquire Coterie, a premium diaper/baby care brand.⁶

Then, in January 2026, Bloomberg reported that Mammoth Brands was again considering an IPO, which could happen as soon as the second half of 2026. JPMorgan Chase, Goldman Sachs, Barclays and Wells Fargo are reportedly working with Mammoth Brands on the IPO.¹

Those are the same banks that were reportedly tapped by Harry's in 2024,³ indicating that there's a through line from the initial reported filing.

Still, as Bloomberg noted, talks are ongoing, and the details, such as the IPO timing, could change.¹ For now, Mammoth Brands remains a private company. Interested accredited investors may be able to access pre-IPO Mammoth Brands shares through a private marketplace such as Forge, subject to availability and eligibility.

Mammoth Brands: Company background

Mammoth Brands originated as Harry's Inc., a brand founded in 2012⁷ by Jeff Raider and Andy Katz-Mayfield. The two had been friends since childhood and also worked together at Bain & Company.⁸

Raider was also the co-founder of Warby Parker, a direct-to-consumer (DTC) glasses company. After Katz-Mayfield reportedly had a bad customer experience buying shaving supplies at a pharmacy, he teamed up with Raider to start Harry's, leveraging some of the learnings from Warby Parker to try to create a better DTC shaving brand geared toward men. That included buying a nearly 100-year-old German razor blade factory shortly after launching the brand.⁹

Using learnings from building out Harry's brand, the company launched an M&A and incubation arm, Harry's Labs (now Mammoth Labs), in 2018. That same year, Harry's launched Flamingo, a shaving/hair removal brand geared toward women.

Since then, Harry's has funded, built and acquired several other modern DTC brands, across areas such as cat food, hair care and deodorant.^10,11,12 The company rebranded to Mammoth Brands in 2025 to reflect its expansion from Harry's.² That said, it sold its cat food brand and wound down a haircare brand, but the company reportedly wants to keep adding "everyday care and wellness" brands.¹³

"Create things people like more"

Mammoth Brands' mission is to "Create Things People Like More",¹⁰ which reflects how the company builds and acquires CPG brands that have some modern, innovative angles, but for the most part, these are brands that improve upon consumer staples. These brands typically have a strong DTC presence with some select in-store availability, too, especially as they scale. And there can be some synergies from bringing these brands together under one house.

For example, in 2021, Mammoth (then Harry's) acquired Lume, a whole-body deodorant brand focused on women. After that, in 2022, Mando launched a similar version for men under the brand Mando,¹⁰ leveraging Lume's founder, OBGYN Dr. Shannon Klingman, M.D., to develop Mando's whole body deodorant.¹⁴

But before Mammoth got too deep into building its own CPG conglomerate, it almost joined forces with another major one. In 2019, Edgewell Personal Care, a publicly traded company that owns brands like Schick, a popular name in razors, agreed to combine with Harry's in a deal that would have valued Harry's at $1.37 billion.¹⁵ But the FTC filed suit in 2020 to block the deal, due to its allegedly anti-competitive nature, which led to Edgewell walking away from the deal.¹⁶

Since then, Harry's/Mammoth has grown substantially. In 2024, before the rebrand, Harry's had $835 million in revenue, almost $100 million in adjusted EBITDA, 20%+ revenue CAGR over the preceding five years, across the Harry's, Flamingo, Lume and Mando brands.² Each of those brands was reportedly generating at least $100 million in annual sales, with Lume bringing in over $300 million.⁵

In late 2025, after rebranding to Mammoth, the company then bought diaper/baby care brand Coterie. At that time, Coterie had reached over $200 million in net revenue over the previous year, which was almost a 60% annual increase.⁶

Mammoth Brands IPO outlook

While there has been speculation about an upcoming Mammoth Brands IPO, no IPO details have been confirmed by the company. Mammoth Brands has not publicly filed an S-1 or announced a listing date.

That said, in March 2024, under its former Harry's name, the company reportedly filed confidentially for an IPO, according to Reuters.³ In January 2026, Bloomberg reported that Mammoth Brands could go public as soon as the second half of 2026, with JPMorgan Chase, Goldman Sachs, Barclays and Wells Fargo reportedly working on the offering — the same banks Reuters reported that Harry's had tapped.¹

However, those plans could still shift. Bloomberg noted that talks were ongoing and that details such as timing could change,¹ and the gap since the reported 2024 filing indicates that the company is not rushing toward the public market. Moreover, now that the second half of 2026 is underway and no additional IPO plans have been announced or clearly reported, it's possible that an IPO could take longer, if it even comes at all. When CNBC asked Katz-Mayfield in June 2026 about that Bloomberg report, he deflected specifics, saying that he didn't know where the report came from. He added that the company is able to use some of its cash flow now, but does want additional access to capital, either through the private or public market.¹³ So, the IPO outlook remains unclear.

Mammoth Brands funding history and private market valuation

Data on Mammoth Brands' funding history is somewhat limited, but publicly available information indicates that its most recent primary funding round came in November 2025, raising $146.08 million at a $2.36 billion valuation from undisclosed investors. That was a slight down round: the $2.36 billion valuation came in below the $2.55 billion valuation from a 2022 financing that raised $140 million from undisclosed investors.⁴

Prior to that, in March 2021, the company raised $155 million in a Series E round co-led by Bain Capital and Macquarie Capital, valuing the company at about $1.7 billion.¹⁷

How to invest in Mammoth Brands before its IPO

Mammoth Brands has not gone public, and as such, its shares are not available to trade via traditional brokerages.

Instead, accredited investors may be able to access shares of some pre-IPO companies like Mammoth Brands through secondary market transactions on private marketplaces like Forge, through which existing shareholders such as employees or early investors may sell their holdings. An accredited investor is a person or entity that meets income or net-worth thresholds, or professional criteria, as set by the SEC.¹⁸

However, private market access can come with constraints. Share availability is not guaranteed, and companies often impose transfer restrictions, including a Right of First Refusal (ROFR) that lets the company or existing investors buy shares before an outside buyer can when an existing shareholder tries to sell. Private company shares are also typically illiquid, especially compared to public market securities, and valuations can be uncertain.
