Descriptiontext

Atlantic Sea Farms is a US-based regenerative ocean farming company headquartered in Biddeford, Maine. Founded in 2009, the company cultivates and harvests kelp (seaweed) at commercial scale using regenerative ocean farming techniques, achieving a record 1.3 million-pound harvest during the 2024 season in Maine coastal waters. The company's core technology centers on large-scale kelp cultivation across ocean farming leases, with operations concentrated along the Maine coast and a workforce of 11-50 employees.

Atlantic Sea Farms sells into a horizontal set of use cases rather than a single vertical. Its primary customer segment is the food industry, supplying sustainable seaweed ingredients for food products. Secondary segments include agriculture (biofertilizers and agricultural applications), biomaterials (raw materials for biomaterials production), and climate-focused supply chains (carbon sequestration and environmental sustainability solutions). Pricing is not publicly disclosed, and revenue mechanics are not detailed in available sources.

The company is privately held and has raised equity capital across multiple rounds, most recently $3.8 million in January 2025 from Builders Bridge, Third Nature Ventures, and True Wealth Ventures. The company has no parent company, no subsidiaries, and no publicly disclosed customer logos or enterprise contracts. In January 2025, Mikel Durham became interim CEO after Briana Warner transitioned to a strategic advisory role.
