Mammoth Brands, the consumer packaged goods (CPG) company behind Harry’s, Flamingo, Lume, and Mando, has announced that it has signed a definitive agreement to acquire Coterie, a fast-growing premium baby care and diapering brand known for its high-performance, clean, and safe products for babies.
This acquisition marks a significant milestone for Mammoth Brands, which continues to grow its portfolio of category-defining, mission-driven brands that blend thoughtful design, product innovation, and consumer trust.
Founded in 2019, Coterie has built a passionate, loyal customer base by prioritizing premium performance, safety, and sustainability. The company has sold over 700 million diapers and achieved over $200 million in net revenue in the past twelve months, representing nearly 60% year-over-year growth. Beloved by parents and endorsed by pediatricians, Coterie leads its category in customer satisfaction with the #1 Net Promoter Score among diaper brands.
Under the terms of the acquisition, Coterie will continue to operate independently within the Mammoth Brands family. CEO Jess Frenchman Jacobs and President Grace Weingard will remain in their leadership roles alongside the existing executive team, including SVP of Growth Ankur Goyal, SVP of Brand Marketing and Partnerships Lindsey Kling, and SVP of People Katherine Donner. They will collaborate closely with Mammoth Brands Co-Founders and Co-CEOs Jeff Raider and Andy Katz-Mayfield to accelerate innovation and scale the company’s impact.
Mammoth Brands, which pioneered its online-to-omnichannel business model with men’s grooming brand Harry’s, plans to apply its proven approach to help Coterie expand product innovation, distribution, and customer engagement while preserving its distinct brand identity and uncompromising quality standards.
The acquisition also represents the second deal led by Mammoth Labs, the company’s dedicated mergers and acquisitions arm. Mammoth’s previous acquisition of Lume in 2021 more than doubled the brand’s size within two years, demonstrating the firm’s ability to grow and scale emerging leaders in consumer health and wellness.
The transaction is expected to close by the end of 2025, pending customary regulatory and closing conditions. Once finalized, Coterie will join Mammoth’s expanding portfolio of category disruptors and strengthen its position as one of the largest and most dynamic CPG companies built in the past two decades.
