Seaweed Snacks Move Beyond the Nori Sheet

Startups like 12 Tides, AKUA, and Umaro raised a combined $40M+ in the past 12 months to scale kelp-based snacks. Whole Foods reports seaweed snack category growth of 38% YoY, outpacing the broader salty snack category by 6x.

Seaweed sits at the intersection of three megatrends: regenerative sourcing (kelp sequesters carbon and needs no fresh water), functional nutrition (iodine, fiber, minerals), and clean-label salty snacking. It's one of the rare ingredients with a credible sustainability AND health story.

Expect kelp and dulse to show up in tortilla chips, popcorn seasonings, and even pasta over the next 18 months. Watch for ingredient-supplier consolidation as demand outstrips US kelp farm capacity.

Gen Z shoppers are the heaviest buyers, drawn by the eco-narrative as much as the flavor. Older consumers still need taste-bridges — kelp-and-cheddar or kelp-and-sea-salt formats convert better than pure seaweed.

Brands evaluating salty snack innovation should secure kelp supply contracts now. US capacity is tight and 2027 prices will move.
