People: Leadership with Vision and Expertise

At the helm of Atlantic Sea Farms is CEO Briana Warner, whose leadership has been pivotal in the company's expansion. With a background in international relations and economic development, Warner brings a unique blend of expertise to the table. Her experience at the Island Institute, where she worked to diversify incomes for Maine's fishermen, laid the groundwork for her mission at Atlantic Sea Farms. Under her guidance, the company has grown its network of partner farmers to 40, harvesting over 1.3 million pounds of kelp in 2024. Warner is supported by a talented team of seaweed scientists, sustainability experts, and market strategists, all united by a commitment to creating healthy, crave-able products that benefit both people and the planet.


Process: A Vertically Integrated Model for Sustainability

Atlantic Sea Farms operates a vertically integrated business model that ensures quality and sustainability at every step. The company produces kelp seeds in their advanced nursery and distributes them to partner farmers—many of whom are lobstermen seeking additional income during the off-season. Atlantic Sea Farms provides these farmers with free seeds, technical training, and a guaranteed buy-back program, creating a stable market for their harvest. This approach not only supports local economies but also promotes eco-friendly farming practices. Kelp farming requires no arable land, freshwater, or pesticides, and it helps improve ocean health by absorbing carbon and nitrogen. Once harvested, the kelp is processed into innovative products like seaweed salads and kelp cubes within 24 hours, ensuring maximum freshness and quality.


Performance: Financial Growth Rooted in Sustainable Practices

Atlantic Sea Farms’ commitment to sustainability is reflected in its strong financial performance. The company has raised $7.32 million over seven funding rounds, including a $3.14 million Series A in 2021, demonstrating significant investor confidence in its business model. This capital has fueled operational growth, with kelp production soaring to 1.3 million pounds in 2024—up from just 53,500 pounds in 2018. Financially, this expansion has had a tangible impact: in 2024, Atlantic Sea Farms paid over $1 million to its partner farmers, strengthening Maine’s coastal economy. Their products are now available in over 4,000 retailers nationwide, including major chains like Whole Foods and Sprouts, signaling robust revenue potential and market demand. While exact financial statements are not public, the company’s scaling operations and broad distribution suggest a solid foundation for continued growth.

Setting a New Standard for Sustainable Growth

Atlantic Sea Farms is more than a seaweed company—it’s a blueprint for blending financial success with social and environmental responsibility. Through visionary leadership, a sustainable process, and impressive performance, they are redefining aquaculture while delivering value to investors, farmers, and consumers alike. As they grow, Atlantic Sea Farms is proving that profitability and purpose can go hand in hand.
