Overview
Mammoth Brands (formerly Harry’s Inc.) is the modern CPG company behind brands Harry’s, Flamingo, Lume, Mando, and Coterie. We’re building a new model—and home—brands, founders, and talent looking to solve unmet needs, improve peoples’ lives, and ultimately challenge the status quo. Our mission is to “Create Things People Like More.” Everything we do should be better than what already exists. This guides everything from product experiences to making Mammoth Brands a great place to work and giving back to our community.
We started in 2013 with Harry’s. We built a brand differently—online first and customer relationships—and created a playbook and platform to help other brands grow. Today, Mammoth Brands is a growing portfolio of brands and the largest CPG company built in the last 20 years. We maintain a small, scrappy, entrepreneurial culture that serves customers, employees, and the community. We have donated over $20 million to nonprofit partners to date.
