Springtide Seaweed

Springtide Seaweed is a Downeast Maine seaweed farm and processor founded by Sarah Redmond, a long-time seaweed farmer and aquaculture educator. The company works out of Gouldsboro and Sorrento, growing and processing USDA organic seaweeds from Maine waters for food, seed, research, and wholesale uses.

The ownership record is clear. Springtide’s own company page identifies Sarah Redmond as founder and describes the business as woman and minority owned and operated. The Maine Seaweed Council lists Springtide among Maine seaweed companies and points to the same Gulf of Maine seaweed ecosystem: edible sea vegetables, powders, extracts, animal and plant uses, and ingredient supply. We found no acquisition record, corporate parent, or exclusion-list match.

Springtide is more technical than the average pantry brand. The company says it operates the largest seaweed nursery in the U.S., produces seed for more than seven seaweed species, runs a registered processing facility, and sells organic powders, flakes, seed, and consulting. That makes the shop useful for home cooks, but also for chefs, researchers, and other seaweed businesses that need traceable supply.

The clean-directory fit is the combination of ownership, place, and process. Springtide is not repackaging anonymous imported kelp under a coastal label. It ties its products to Frenchman Bay, solar drying, USDA organic handling, and a founder who has been building seaweed farming infrastructure since 2010.

For everyday buyers, the best entry point is simple: organic kelp, dulse, and other seaweed powders or flakes from a Maine grower with visible leadership. Check individual product pages for species, format, and intended use, because Springtide sells both food and industry-facing materials.

One caution: this is not a polished snack brand with flavor-first copy. Some products are ingredient-grade and some are meant for growers or processors. That specificity is useful. It tells you Springtide is doing real seaweed work, not just selling a trend.
